Ladies and gentlemen, thank you for standing by and welcome to TransAlta Corporation Third Quarter 2019 Results Conference Call. [Operator Instructions] I would now like to hand the conference over to your speaker today, Chiara Valentini, Manager, Investor Relations. Thank you. Please go ahead.
Chiara Valentini -- Manager, Investor Relations
Thank you, Chantal. Good morning, everyone, and welcome to TransAlta's third quarter 2019 conference call. With me today are Dawn Farrell, President and Chief Executive Officer; Todd Stack, Chief Financial Officer; John Kousinioris, Chief Operating Officer; and Brett Gellner, Chief Development Officer.
Today's call is webcast, and I invite those listening on the phone lines to view the supporting slides that are currently available on our website. A replay of the call will be available later today and the transcript will be posted to our website shortly thereafter.
As usual, all of the information provided during this conference call is subject to the forward-looking statements qualification set out here on Slide two. Detailed in our MD&A and also incorporated in full for the purposes of today's call. All amounts referenced during the call are in Canadian currency unless otherwise noted. Non-IFRS terminology used, including comparable EBITDA, funds from operations and free cash flow are also reconciled in the MD&A for your reference.
On today's call, John and Todd will review the quarterly and year-to-date results and expectations for the remainder of the year. In addition, we'll provide commentary on our recent announcements and how these advance our clean energy investment plan and growth strategy that we outlined at our Investor Day back in September. After these prepared remarks, we will open the call for questions.
And with that, let me turn the call over to Dawn.
Dawn Farrell -- Corporation Chief Executive Officer and Corporate Director
Okay. Thanks, Chiara and welcome everyone to the call today. We're pretty excited to be here announcing our third quarter results. We did have a strong third quarter and we're pleased with the results across results across all of our businesses. And, of course, strengthen in the third quarter has given us strong performance year-to-date and it's increased our expectations for annual performance. Now, overall, our operational and financial performance is tracking to deliver a strong year, our clean energy investment plan and growth strategy is on track and through the quarter, we had key milestones, which I think has been very impressive in terms of what the team has done.
And finally, we successfully concluded the final leg of our Sundance PPA arbitration and collected an additional one-time payment of CAD56 million from the balancing pool, which is great news, because that has added to our cash flow for the year.
So I'm going to just start with a couple of overall comments on our financial performance and, of course, Todd will get into more of the detail. We earned a total of CAD305 million of comparable EBITDA in the quarter due to strong performance at our Canadian and US coal businesses, our energy-marketing segment -- from the efforts and the work that's been done across the Company to reduce our OM&A costs and, of course, because of the one-time PPA payment. Now, if you take out the one-time PPA payment, our EBITDA was flat for the quarter relative to last year. Now, what's important here is that, the Mississauga and Poplar Creek contract changes that occurred at the end of 2018 were expected to reduce our EBITDA in the quarter by approximately CAD30 million. So, to be able to deliver flat year-over-year EBITDA with these changes, shows that we've been able to increase performance in our remaining key business segments. We see this increased performance as sustainable for a number of reasons, and we'll talk with you about that through the call.
In total, we've now received CAD213 million from the balancing related to the termination of the Sundance PPAs. I'm especially proud of our team, they held a strong view that the mining assets were part of the PPA, and I believe that the final payout was a very principal decision.
Overall, our free cash flow results for the quarter are also trending ahead of 2018 and the results are -- for the quarter were in the following areas. Now, first of all, strong availability -- we saw strong availability across the fleet with some of the strongest availability results that we've seen. The entire fleet had availability of 95.2% for the quarter compared to a pretty high availability in last year in 2018 of 93.7%. This was due to fewer unplanned outage hours and fewer derates at both the Centralia and the Sundance unit.
Now, although the Alberta market saw weaker prices in Q3 relative to 2018, we continue to maintain high realized prices for Alberta coal fleet with an over 40% premium to the pool price. Our fuel and carbon costs per megawatt hour were lower due to the availability of -- due to the ability of the Alberta coal units to co-fire with the Pioneer pipeline gas, which did come on line four months ahead of plan, which was just excellent results by the team. Overall, comparable gross margins at Canadian Coal have improved, primarily due to the benefits of co-firing, we expect to realize further co-firing benefits as we reach from throughput of approximately 130 MMcf per day of natural gas commencing this month.
Centralia delivered a strong quarter despite lower pricing in the Pac Northwest, due to their higher availability from fewer planned outages, and strong performance in Q3 enabled us to partially recover some of the loss that they experienced in the first quarter. And, of course, we continue to deliver OM&A reductions as we transition the fleet. Year-to-date, we're tracking to 7% reduced OM&A compared to last year.
As we look forward to the balance of 2019, we continue to expect strong performance from our businesses. Year-to-date results combined with our forecasts, provide us with the confidence to both revised and tighten the free cash flow range CAD300 million to CAD340 million for the full-year.
So let me turn now to talk about our strategy. Just before I talk more about the milestones we achieved, I do want to briefly comment on the care program that the government of Alberta announced last week. In short and simply put, it was exactly what we expected. The carbon levy will remain at CAD30 a ton, with a performance standards for our business, which is at 0.37 which is about (ph) gas. This standard will be reviewed every five years. We finally have clarity on the credits that we'll receive across our extent of renewable suite in Alberta. All of our Alberta wind and hydro assets will receive Green credits for their generation based off the previously mentioned performance standard. We expect these credits to be worth approximately CAD30 million annually at the current carbon prices. The clarity on this policy and renewable credits are yet another step in the right direction that support this strategy that we've laid out for you here in Alberta.
So let me now turn to our strategy. We are very pleased with the progress we made through the quarter on our clean energy investment plan. Last week, we move forward with the acquisition of two 230 megawatt Siemens F class gas turbines and related equipment by buying the Kineticor business. TransAlta will redeploy these assets to its Sundance site as part of its strategy to repower Sundance Unit 5 to a highly efficient combined cycle unit, by integrating these gas turbines into the existing steam turbines.
The acquisition also results in the Company assuming a long-term non-unit contingent power arrangement starting in 2023 with Shell. A strong investment-grade company that is also committed to providing more and cleaner energy for Albertans. This advances our coal-to-gas conversion project by three to six months.
Our initial plans discussed at Investor Day included possible repowering options at both Sundance Unit 5 and Keephills Unit 1 for combined cost of about CAD1 billion and total megawatts of 1,180. Changing the plan slightly and installing the two F class turbines together at Sun 5 will provide 730 megawatts of capacity earlier than expected at a cost of approximately CAD760 million.
We like that this plan allows us to have more flexibility in dispatching with two units and it gets us to the market with cleaner energy sooner. We do retain an option to repower Keephills 1 to have the conversion in 2022 as an interim step. And, as you all know, the carbon levy here in Alberta has a quick payback, which provides a clear incentive for us to really consider this decision.
In the meantime, we will also continue to permit Keephills 1 as a combined cycle and we -- and continue to execute the project to meet the financial targets that were outlined at Investor Day as we move into a fully deregulated market.
For the remaining coal fleet, the boiler conversions are well under way. In early July, we issued final notice to proceed on our Sundance Unit 6 and are planning to complete the conversion of that unit in the second half of 2020. We have also -- we have since also issued limited notice to proceed for the Keephills Unit 2 coal-to-gas boiler conversion.
Our onsite generation strategy -- on our onsite generation strategy, we told you at Investor Day that we were expecting to potentially announce a project, which we did. We executed an agreement with SemCAMS Midstream to construct and operate a new cogeneration facility. Subject to the satisfaction of certain conditions, SemCAMS will purchase 50% of the product COD and detailed construction activities have commenced and COD is targeted for mid-2021. Our investments in renewable energy projects under construction are also progressing to plan. All the tariffs and turbines are now fully erect at both sites, Antrim and Big Level big level are on track to deliver COD by later this year in 2019.
Windrise execution has also commenced, we were excited and actually surprised, but very excited to receive AUC approval for the Windrise project ahead of schedule, providing schedule providing further opportunity to optimize the construction costs and integration, and Windrise is targeted still for a 2021 COD date.
Turning to Slide seven. You can see how these growth projects will lift our future EBITDA. We expect to see the benefits of Big Level and Antrim later this year and next year we'll start to see some of the benefits from Skookumchuck as it comes into service sometime mid-year. By 2022, we expect to have approximately CAD60 million of EBITDA added to our run rate. And over the next three years, we will have commissioned six projects which required a capital investment of approximately CAD890 million.
So, I'll now turn the call over to Todd to walk you through a greater detail on our financial results in the quarter and year-to-date.
Todd Stack -- Chief Financial Officer
Thank you, Dawn, and welcome to everyone on the call. Before I jump into the financial and operational results, I would like to start by reviewing the Alberta and Mid-C power price trends and what we're expecting for the remainder of the year. In Alberta, power price during the quarter was weaker when compared to last year, primarily due to a cooler than normal summer in the province, which reduced the number of high load days. The average price in the third quarter was CAD47 a megawatt hour compared to CAD55 per megawatt hour in 2018. Even with the lower average market price, our merchant coal assets performed well and we are able to realize the power price significantly higher than the average pool price.
For the remainder of 2019, forward curve is in the CAD58 per megawatt hour range. However, we are highly hedged with approximately 85% of our expected production in Alberta hedged for Q4. For the full-year 2019, we expect power prices to average approximately CAD57. As we look at 2020, the final year where Alberta assets will be under their PPAs, the forward curve is around CAD55 per megawatt hour, which is supportive of our merchant fleet in the province.
The Mid-C price in the Pacific Northwest settled at $28 per megawatt hour for the third quarter compared to $46 per megawatt hour in 2018. Pricing in 2019 represents a more normalized level, whereas 2018 was positively impacted by a very strong demand in the US West region. For the balance of 2019, production of our Centralia facility is about 85% hedged.
Slide nine breaks down the performance of our Canadian Coal fleet and helps highlight the benefits we are seeing from decisions made in 2018. While overall revenues and productions were lower in Q3 compared to 2018. Comparable gross margin improved from CAD103 million to CAD106 million in 2019.
On a per megawatt hour basis, gross margin in Q3 improved year-over-year by 13%. Excluding the one-time CAD56 million PPA settlement received in Q3, comparable comparable EBITDA increased by CAD6 million from CAD73 million last year to CAD79 million in 2019.
EBITDA margins increased by CAD5 per megawatt hour from CAD21 per megawatt hour to CAD26 per megawatt hour in 2019. This represents an approximate 24% improvement to EBITDA margins driven by both higher realized price and lower fuel and carbon costs.
In Q3, our average realized price per megawatt hour was CAD67 versus the average coal price of CAD47. Higher realized prices are driven by ongoing hedging, revenue from ancillary services sales and effectively dispatching our plants during high-priced periods.
We continue to see lower fuel carbon costs and purchase power due to the increase in coal firing during the quarter where we benefited from additional gas provided from the Pioneer pipeline. Co-firing, not only lowers the cost associated with the missions, but due to the low AECO gas price which averaged around CAD1 per GJ during the quarter. Co-firing greatly reduce the input cost to generate the power. The firm contract in the power Pioneer pipeline began November 1st, which will further increase our ability to operate on gas. For the nine months ended September 30th, the trend is similar.
Excluding the PPA settlements, EBITDA Canadian Coal increased from CAD184 million in 2018 to CAD208 million in 2019, a 13% increase. EBITDA margins improved from CAD17 a megawatt hour to CAD22 per megawatt hour nearly a 30% improvement in margins.
Our overall results for the third quarter were strong and modestly above our expectations. Comparable EBITDA, excluding the PPA settlements, was similar compared to 2018, with free cash flow increasing by CAD20 million to CAD114 million in 2019 versus CAD94 million in 2018. This was a result of strong performance from our business and lower sustaining capital spend in the quarter. Keep in mind that these numbers include the loss of Mississauga and the Poplar Creek contract changes, which previously provided about CAD30 million of EBITDA in the third quarter of 2018.
On Slide 10, we've bridged our year-to-date EBITDA and segment cash flows for 2019 versus 2018 and we've shown the impact of the contract changes to our results. Excluding the impact of these known changes -- these known contract changes, we delivered EBITDA and segment cash flows higher than last year and in line with our expectations for the three and nine months ended September 30th.
Similar to last year, our energy marketing team generated strong cash flows of CAD30 million in the third quarter. For the nine months ended September 30th, cash flows from the energy marketing business have delivered CAD51 million better than 2018. Energy marketing continues to deliver strong cash flow, primarily due to the gain they experienced in the Pacific Northwest in Q1, as well as their ability to capitalize on high levels of volatility across North American power markets. The results come from real-time and day ahead trading in the Western market and have a positive impact on cash in 2019 without increasing the overall risk profile of the Energy Marketing business segment.
In the Canadian Gas segment, excluding the impact of contract changes, EBITDA improved by CAD3 million in the quarter and CAD14 million for the nine months ended September 30th, when compared to 2018. The improvement was primarily due to lower OM&A compared to the prior year and lower fuel costs at Sarnia due to less steam demand from customer planned outages.
Our hydro business delivered good results, generating EBITDA of CAD28 million in the quarter and CAD92 million for the nine months. When compared to last year, hydro for the third quarter of 2019 had higher generation due to higher water resources. However, total gross revenue decreased slightly due to unfavorable power and ancillary pricing in the quarter. After net payments relating to the Alberta hydro PPA, comparable EBITDA for the three and nine months ended September 30th was consistent with the same periods in 2018.
As described on Slide 9, Canadian Coal delivered significantly higher EBITDA in the third quarter and nine months versus 2018. However, this improvement was offset by lower results at US coal due to the unplanned outage in Q1. Coal segment cash flows were also negatively impacted by the additional planned maintenance at Sundance Unit 4 and on Keephills Unit 1. There were no planned outages in 2018 in our Canadian Coal business.
On Slide 11, we're again showing the buildup of our hydro PPA EBITDA to help illustrate the upside of the hydro assets once the PPA expires at the end of 2020. For the nine months ended September 30th, our hydro assets generated CAD92 million in EBITDA. However, they would have generated CAD202 million if the current PPA obligation payments did not exist.
Lastly, I'd like to provide updates on a few other points. As most of you would have seen from our press release this morning, we have revised our free cash flow outlook range upwards for the full-year 2019. Our prior range of CAD270 million to CAD330 million has been shifted to the new range of CAD300 million to CAD340 million based on the continuing strong performance from our business. I would note that the one-time PPA settlement of CAD56 million is not included in this outlook but does represent additional cash available to us.
Liquidity was very strong in Q3 with CAD1.4 billion available on credit facilities and with CAD300 million of cash on hand. The cash balances are due to a combination of proceeds resulting from the PPA settlement, positive working capital balances through collateral, timing of capital spend and proceeds from the investment by Brookfield. This liquidity has given us the flexibility to be opportunistic with our equipment acquisitions and funding of our coal-to-gas investments.
During the the quarter, we returned CAD6 million of capital to shareholders through our share buyback program. Our repurchases in the quarter were well below plan, driven by an extended blackout period caused by our Q2 reporting cycle and the timing of our Investor Day. We expect to resume share purchases in Q4 and plan to continue to return up to CAD250 million to common shareholders over the next three years through our NCIB.
In addition to our boiler conversion and repowering projects, we have four gas and renewable projects at various stages of development and construction. All of these projects Windrise, Windcharger, Skookumchuck and SemCAMS have long-term contracts with strong counterparties and would fit well with RNW existing asset base. We continue to assess these assets for dropdown.
And finally, at our Investor Day in September, we provided insight on a deconsolidated view of TransAlta for FFO and for debt-to-EBITDA. In this quarter's financial report, we provided additional disclosure on how these metrics are calculated. We will continue reporting these numbers in our financial disclosures going forward.
With that, I will now pass the call back to Dawn to provide a brief summary before questions.
Dawn Farrell -- Corporation Chief Executive Officer and Corporate Director
Great. Thanks, Todd. So I've got a short summary -- a short wrap up here. In summary, I'd like to conclude with my perspective on our execution plans and the advances we've made on our repowering. The acceleration of the combined cycle unit at Sundance Unit 5 is a great example of how having a focus and clear strategy allows us to take actions that enhance our plan and shareholder value by capitalizing on market opportunities as they present themselves. The proceeds from the Brookfield investments on earlier this year provided funding flexibility, which was demonstrated by our opportunistic purchase of the equipment from Kineticor.
We also see enormous value in having a long-term hedge with a credit-worthy counterparty as an excellent addition to our portfolio. This enhances the financial flexibility of the Company and we do believe that investors and creditors value our portfolio that has a portion of the cash flows locked in as these projects come onstream and into the market. The Sundance 5 repowering is now larger than previously assumed. And so, it does bring forward future cash flows. Keephills 1 is now more likely a candidate for a simple conversion in 2022 and it will still be permitted for a combined cycle unit in the mid-2020s.
We showed you at Investor Day the simple boiler conversions have very short paybacks, and that will be even shorter if the carbon levy escalates with the current expectations under the federal policy schedule.
We look forward to providing further feedback in late January in terms of our annual outlook and guidance. Overall, I'd like give many, many thanks of the TransAlta team and our employees, they worked extremely hard through the quarter. You see the results and you see all the milestones they achieved and they are just moving everything ahead for this Company. So, thank you.
And with that, I'm going to turn it back over to Chiara.
Chiara Valentini -- Manager, Investor Relations
Thank you, Dawn. Chantal, would you please open the call for questions from the analysts and media?
Questions and Answers:
Operator
[Operator Instructions] Your first question comes from Rob Hope with Scotiabank. Your line is open.
Robert Hope -- Scotiabank -- Analyst
Hello, everyone. Thanks for taking my questions. First question is on Canadian Coal, just want to dive a little bit further into the fuel and purchase power savings that you're getting there. Is there a way to quantify the benefit that you saw from Pioneer in Q3? And then as we look into Q4 and 2020, is it fair to assume that absent moves in gas pricing that we could see on a per megawatt hour basis similar fuel and purchase power costs moving forward?
Todd Stack -- Chief Financial Officer
Yes, it's Todd here. I don't have a specific number for you, but the trend that you saw over the summer, I would say, we're going to increase the volumes significantly in 2020 over the amount of co-firing as that contract steps up to the full capacity of about 130 MMBtus per day. So we'll see more co-firing. We did see very attractive prices on gas over the course of the summer, which did help during that period. Over the course of the winter, we've actually procured a fair amount of our gas needs over the course of the winter, but, as you know, pricing on gas shifts quite a bit between summer, and winter profiles. So, I think you'll continue to see definite savings trends from both the fuel cost, as well as the avoided emissions costs as we go into 2020.
Brett M. Gellner -- Chief Development Officer
Yeah. And the only -- it's Brett. I mean, just simply on a carbon basis, if you take a typical coal unit at CAD30, I think it's about CAD18 a megawatt hour. And then when you're burning gas, I think you're closer to CAD6. So, a difference of about CAD12 per megawatt hour on the gas portion. So, if you think about burning kind of 139 TJs a day in around that zone just co-firing, that is the carbon saving multiplied -- convert that into a megawatt hour and you can get the savings.
Dawn Farrell -- Corporation Chief Executive Officer and Corporate Director
So Rob, did that help?
Brett M. Gellner -- Chief Development Officer
Yes, that's great. Thank you.
Dawn Farrell -- Corporation Chief Executive Officer and Corporate Director
Okay.
Robert Hope -- Scotiabank -- Analyst
And then more broadly speaking, we've seen you move forward with SemCAMS on a co-gen, we've seen Suncor do one, as well as Pembina do a small co-gen as well and speak about further co-gens. How are you thinking about increasing behind the fence generation and how it would affect forward pricing and kind of the overall supply demand mix in Alberta?
Dawn Farrell -- Corporation Chief Executive Officer and Corporate Director
Well, I mean, we've seen -- if you go back and you look at loads growth in Alberta and you look at how it's been supplied, I mean, it's a lot of load growth from 2000 until 2019 was supplied by a combination of investments that we made and the co-generation. So as we look ahead, our models do incorporate a lot of co-generation going forward as we set out forward prices and think about our investments.
Just remember that 99.9% of what TransAlta is doing is replacing existing supply and we've actually taken supply out of the market. So because we've shutdown Sundance units 1 and 2. So, we don't -- so as we look at our estimates of pricing, we incorporate in co-generation, I mean, you can -- sometimes it's half and half, sometimes it's two-thirds, one-third in terms of how new growth is supplied. But you really have to look at where the developments are in the province, you have to look at who can add co-generation, you have to assess that against the ISOs plan for growth and our plan for growth. But net-net, Alberta has been supplied significantly by co-gen and it's a great way to supply the market here.
Robert Hope -- Scotiabank -- Analyst
All right. Thank you. I'll hop back in the queue.
Dawn Farrell -- Corporation Chief Executive Officer and Corporate Director
Great. Thanks, Rob.
Operator
Your next question comes from Robert Kwan with RBC Capital Markets. Your line is open.
Robert Kwan -- RBC Capital Markets -- Analyst
Great. Thank you. Maybe I'll just kind of continue on the co-gen side. I'm just wondering in your kind of detailed modeling and expectations, how much co-gen, do you think is that will be developed is going to be meeting new demands associated with -- as we've seen with new industrial facilities versus co-gen that we're seeing being built to meet existing demand effectively taking them off the grid?
Dawn Farrell -- Corporation Chief Executive Officer and Corporate Director
Yeah. Robert, we see that as proprietary information. So we don't share that kind of detail with the market. I mean, if you -- you can -- I think EDC potentially have some ideas there that you can look at, it's public, but maybe Brett.
Brett M. Gellner -- Chief Development Officer
Yeah. I am the -- Robert, the ISO just published their long-range plan and I think it's a good source, because I think they try to predict what the mix will look like. But you'll see, they've got pretty good growth still projected and more combined cycle coming into serve that growth.
Dawn Farrell -- Corporation Chief Executive Officer and Corporate Director
Yeah. Just broadly, if you want to think about the decision-making now, when I think about the last 20 years, I mean, it's been here the whole time. What I've noticed about the co-gen is an incremental capital decision by an oil and gas company. So you have to be a company that has significant cash flows that you have nothing to do with to want to allocate capital over there. We do find that We do find that people will start with pretty large ambitious projects and then over time they narrow down as they get closer and they start with, I'm going to do it all myself, over time they tend to go look for a partner in co-generation.
So when I'm doing the analysis or when we're doing analysis with the team, we do our risk assessment of every project based on the actual underlying cash flow of the Company. And, I mean, all else being equal, most oil and gas companies would be putting their capital toward what they do best and the returns that they get out of their business and it's a secondary impact, but that's been the trend over the last 20 years, it could change in the future but that's how we look at it.
Robert Kwan -- RBC Capital Markets -- Analyst
Got it. If I can just finish on the AESOs market power mitigation proceedings and just your thoughts after looking at others submissions, it seems like many were supportive of the current framework like you were, but there were also -- I'm wondering you can comment also specifically on a couple of submissions talking about dealing with single participants on a one-off or case-by-case basis?
Dawn Farrell -- Corporation Chief Executive Officer and Corporate Director
Yeah. How interesting [phonetic]?
Robert Kwan -- RBC Capital Markets -- Analyst
You can go figure.
Dawn Farrell -- Corporation Chief Executive Officer and Corporate Director
I'll try not to say what I want to say on this. But I think at the end of the day, when I look -- again, when I look back over the last 20 years, there have been situations where the buyers in the marketplace had significant market power. And the Alberta market adjusted to that using their FEOC regulation and using the OPEC and a number of different ways to ensure that we had an efficient market through the whole for the last 20 years.
So my belief is that, if you actually look at kind of a light touch here, we've already got in place all of what's necessary to ensure that participants don't engage in market power behaviors. We also have an obligation under FEOC to make sure that we a positive obligation to make sure that we're not doing anything that would express market power. So that's an important thing for TransAlta and we've got the value set in this Company to adhere to that, as you know.
So I think -- I don't know what to expect, you never know what regulators are going to do. But I do know that if people participate in market power behaviors here in the market, they will be investigated by the MSA, number one. And number two, they will keep prices in a range that will bring on more supply. So I don't know why they would do that, and I think we've had 20 years of experience, creating a competitive market with a robust spot market price. And so, I have a lot of confidence that the market works today.
Robert Kwan -- RBC Capital Markets -- Analyst
Okay. That's great color. Thank you.
Operator
Your next question comes from Mark Jarvi with CIBC Capital Markets. Your line is open.
Mark Jarvi -- CIBC Capital Markets -- Analyst
Yeah. Hi, everyone. Maybe I just want to talk a little bit on the shift in the Sundance repowering, two questions, I guess is, one is the capex per megawatt goes up. What are sort of the offsets to preserve the returns? You guys talked about the Investor Day. And then any incremental views on what to do with Sundance 3 and 4?
Dawn Farrell -- Corporation Chief Executive Officer and Corporate Director
So I'm going to turn it over to Brett.
Brett M. Gellner -- Chief Development Officer
Yeah. I mean to -- as Dawn mentioned, this really helps us to some extent advance the opportunity. So we see that as return enhancing. But at the same time, remember, by getting a long-term contract here provides a lower risk investment too for us and we think that's very positive. And so, when you blend all that together, we see the returns still very attractive from a risk-adjusted basis.
In terms of the other units, yeah, we're still -- no change from what we communicated at Investor Day. We'll still evaluate those come into the new year -- next year. And it's fundamentally really on the outlook for the market fundamentals. But also as Dawn says, just the payback on some of these, as we said at Investor Day, is pretty high on simple conversion. So, we'll take next year to evaluate that and keep you posted.
Dawn Farrell -- Corporation Chief Executive Officer and Corporate Director
Yeah. I'd say, Mark, a couple of things from my perspective. So having been in the business for long time I tend to be a proponent of those workhorse-type machines that the [Indecipherable] are, they're excellent to operate, they're stable and they have a -- and when you look at the overall life of contract and you look at the maintenance cost to go along with those kinds of machines, they're typically lower than some of the newer machines that may have a slightly higher key [Phonetic] rate but are much more expensive to maintain. So, that's one thing.
Number two, remember, we have a portfolio, so we can actually do something like this and then do a different kind of configuration at a different plant. And when you blend everything together and you run the math, we get some benefits out of the diversification and we do get significant benefits out of having two machines on one steam turbine. So that allows us some dispatch capability as well.
I think the final thing is, if you look at the Federal rules on carbon tax, for the province here to stay in compliance with the Federal Program and, of course, we just had an election here, and we know what the Federal Program is going to look like. The Federal Program goes from CAD30 to CAD40 to CAD50 by 2022. So getting on gas sooner getting on gas sooner and saving our greenhouse gas reductions makes a huge difference. Overall, these machines are here, they're built, they're ready to go, that make -- that significantly reduces construction risk and execution risk. So we factored all of that into our decision-making.
Mark Jarvi -- CIBC Capital Markets -- Analyst
Okay. And then, is there any other sort of additional benefits of doing that transaction by those turbines by essentially potentially getting those out of the hands of someone else you might have build more capacity in the market, was that all in sort of the motivation for that deal?
Dawn Farrell -- Corporation Chief Executive Officer and Corporate Director
Well, no, not really. I mean, at the end of the day, we would only -- we could only put a pricing for those assets that would work in our portfolio. So at the end of the day, I don't know what they were planning on doing. I didn't really care. I just know that Brett and his team had a bit of a sense that this was a way to accelerate our program and the Kineticor guys, I think saw that as their best opportunity.
Mark Jarvi -- CIBC Capital Markets -- Analyst
Okay. And then, we've seen some commentary and some deals around either merchant or corporate PPAs for wind or solar in Alberta. In the past, you guys have indicated you didn't think merchant win was great for just how you guys seeing [Phonetic] more financing your business and funding growth. But what about the prospects of finding commercial industrial offtakes for renewables in Alberta, is that something you guys see as increasingly something you could work toward?
Dawn Farrell -- Corporation Chief Executive Officer and Corporate Director
Yeah. Listen, we've had a team that's been talking to people quite a bit on that. We already have quite a bit of merchant wind, we don't need to add to our merchant wind portfolio. And as you saw from the tier, we now have some additional revenues coming in because of the carbon offsets that they provide. And we've got some of the best wind that there is, really, and we'll have Windrise coming on and all the rest of that. So my view is, the team talk to every industrial customer here, and if there is opportunities to build for people, we would do it -- we would encourage them not to build new and to use some of the existing because it does have a -- it's good wind and it was built on a good time, it's got a good cost structure. But net-net, we'll see -- what I know is if you build more wind in Alberta, you're going to need our coal- to-gas because the wind blows here are pretty well at the same time and you need to back it up.
Mark Jarvi -- CIBC Capital Markets -- Analyst
Okay. And my last question is maybe around TransAlta Renewables and dropdowns, you talked about Skookumchuck and Windrise. Is there an optimal timing around you guys would think about a transaction or any sort of the factors that go into how you think about sequencing dropdowns to TransAlta Renewables?
Dawn Farrell -- Corporation Chief Executive Officer and Corporate Director
Well, if we told you that we'd have to kill you. There is always an optimal timing and you'll hear about it when everybody else does.
Mark Jarvi -- CIBC Capital Markets -- Analyst
Okay. Thanks.
Dawn Farrell -- Corporation Chief Executive Officer and Corporate Director
Okay. Thanks.

Your next question comes from Jeremy Rosenfield with Industrial Alliance. Your line is open.
Jeremy Rosenfield -- Industrial Alliance Securities -- Analyst
I'll try not to ask any questions it'll get me killed. Just on -- thoughts on the supply cushion, Brett, you referenced today so publishing the update and the supply cushion looks like in winter gets to be pretty tight, both this year and probably next year as well. So, any thoughts on your positioning the portfolio, looking forward for potential upside in trading revenue and that type of thing?
Brett M. Gellner -- Chief Development Officer
Yeah. I mean, as always, winter would be just given the load increases that go on. So yeah, we just -- I mean there is no -- I don't think any change to what we are -- they have been doing. We'll position the fleet accordingly, we're really looking more long-term on the investments. So Todd, I don't know if he --
Dawn Farrell -- Corporation Chief Executive Officer and Corporate Director
Yeah. Maybe a way to think about it Jeremy is that, Todd talked about -- I think he, our hedge portfolio was at 85%...
Todd Stack -- Chief Financial Officer
Pretty highly hedged was down.
Dawn Farrell -- Corporation Chief Executive Officer and Corporate Director
Yeah. Pretty highly hedged. But you'll see that it's not 100% hedged. And the reason, as you know, is in Alberta being short of supply when a whole bunch of coal plants decide to take a rest on a cold day is a disaster. So we tend to carry production into the year in order to be able to withstand that.
The second thing is, because we now have our Sundance 2 merchant, right. So they pretty well sit there and wait for those days and we have the ability to capture some of that, when it does occur if it does occur.
Now, you also have to remember it is Alberta, so we have that -- I think the wettest summer probably ever, coldest summer we've ever seen. Everybody is expecting really cold winter and you never know in Alberta, we could have the hardest winter ever. So anybody who thinks, I can tell you, I've looked at thousands of years of weather data, list the thousand. I looked for correlations all over the place and it's around a mark. So the supply cushion could be short under cold weather conditions and it could be fine if the weather tend to be mild. And nobody knows what the weather will be.
Jeremy Rosenfield -- Industrial Alliance Securities -- Analyst
Okay. I'm hoping for weather for skiing, but anyway for -- if we look at the same thing looking farther out. So if you think about the merchant portfolio in Alberta from a long-term perspective, maybe 2025 and outward after you're through all your boiler conversions, after you're through repowering. Is there a hard number or something -- somewhere where you want to get the portfolio in Alberta to? So from a long-term basis, so that you have some kind of hedge position or hedge position or long-term contracted position on a sustainable basis going forward?
Dawn Farrell -- Corporation Chief Executive Officer and Corporate Director
Yeah. Yeah. You're thinking about the -- what we've got. You're thinking about the Shell contract, would we want more of those in our portfolio? Is that how you're evaluating?
Jeremy Rosenfield -- Industrial Alliance Securities -- Analyst
Yes. Correct.
Dawn Farrell -- Corporation Chief Executive Officer and Corporate Director
Yeah. Yeah. That's -- so, as you know, we're pretty conservative here and the management team tends to like long-term contracted assets, even if they have slightly lower returns than merchant because that's our DNA, right? So, I would say, that we've still got a lot more work to do. I wouldn't really want to give you any sort of -- I don't want to say something here that will go away and do some analysis on and then regret. But, I would say having some portion of our fleet contracts that is going to be a -- it's always going to be good, especially I really like to have a portion of something hedged when it's coming online, because typically when plants come online, it depresses the price a bit, so you kind of want to have some of that in there.
I think the other thing that we have to do, Jeremy, is, there will be a lot of analysis on what Alberta looks like when there is more of -- when our fleet is more on gas. Gas runs at higher availability and tends to -- it doesn't tend to have some of the same issues as franking [Phonetic] cycle coal does. So we'll have much more operational flexibility when we get out there. And I think if we mix the operational flexibility with our desire to have some consistent cash flows in our portfolio so that we have -- so that Todd will be happy when he goes to finance bonds and will have lower rates on that, we'll be doing all that next. And more to come on that. It will take a bit of time to think that all through. But in general, if we could get other long-term contracts with large industrials that are creditworthy, you would see us trying to engage in those.
Jeremy Rosenfield -- Industrial Alliance Securities -- Analyst
Okay. That's great. I appreciate that. That's it for me. Thanks.

Your next question comes from Patrick Kenny with National Bank. Your line is open.
Patrick Kenny -- National Bank Financial -- Analyst
Good morning. Yeah, just back on the Sun 5 PPA, I know you can't provide too much detail. But I'm just curious in general, how you think about IRR for high-quality PPAs in Alberta relative to building merchant? If you're going to be looking at potentially additional corporate offtake agreements, what would you say is the fair spread and hurdle rate between merchant and contract?
Todd Stack -- Chief Financial Officer
Yeah. I mean, it's a little tough to answer that because we do look at it truly from a portfolio and we'll always have a merchant component, for example, our hydro is a merchant to be able to capture those kind of peaks, but -- and you got to remember the contract is not unit contingent per se, even though you reference it's signed to it signed to the specific unit. But yeah, I mean, I would say, generally you are going to look at probably 300 basis -- 3% higher for merchant. But again, it's a bit dependent on the technology, the age, where it's situated, what market you're in, so that's just a broad rule of thumb.
Dawn Farrell -- Corporation Chief Executive Officer and Corporate Director
Yeah. I would say, take that 300 basis points as a bit of a midpoint and think about it this way, the longer the contract, the fewer the base you might have -- you might take even a bigger reduction. The more pass-through of costs, the more it's tied to actual heat rate of the machine. So there's a number of considerations there. But generally you pick up stability in your cash flows, better financing costs, a whole bunch of things that you can plan around that kind of offset those reductions and returns.
Patrick Kenny -- National Bank Financial -- Analyst
Okay, thanks. That's helpful. And then, you mentioned the lower gas prices in the summer having a positive impact on co-firing margins. I guess, at the same time, it's reduced drilling activity in the central part of the province. So, perhaps you could just provide a bit of an update on how you're thinking about ramping up volumes through Pioneer over the course of 2020, 2021, as well as just securing long-term supply through the other pipelines coming into Sundance and Keephills?
Brett M. Gellner -- Chief Development Officer
Yeah. So we're -- again, no real change from what we communicated at Investor Day. We're targeting to get up to that 350, 400 a day eventually once we're fully converted. We are well positioned here over the next year or so given the Tidewater Pipeline plus, we indicated, we have incremental firm capacity and the existing line there. And so, yeah, it's just a matter of working with parties.
The drilling activity always ebbs and flows and we never saw these low, low prices being sustainable for the producers and that's not in our planning. So we do expect those to improve and drilling to be sufficient. And, yeah, so we will -- as I said, at Investor Day we'll keep you updated as we advancing our plans.
Dawn Farrell -- Corporation Chief Executive Officer and Corporate Director
Yeah. And I think, Patrick, we are talking to a lot of guys as you can imagine. Really our volume is -- even though it seems like a lot of gas to us are -- they are in that rounding area of what Alberta producers in terms of gas, so that's helpful. What we do know is that, this curtailment, whatever they did with TransCanada, this summer that alleviated some of the curtailment issue, so that the guys could get their could get their gas into storage has helped to increase prices to get them closer to what you're seeing today. Those kinds of prices were what we had in our models, because remember that, we're using gas and the offset is what we got to pan [Phonetic] carbon. And so, net-net, what we know from -- we've got gaps -- we've had gas guys on our Board and we've got John Dielwart on our Board. But as you get into this current pricing regime that we're seeing, the guys get out there drills again. So because they become more profitable. So we're starting to see evidence of that.
Patrick Kenny -- National Bank Financial -- Analyst
Okay. That's great. Thanks. And then, just lastly on the NCIB, stock is up nicely here this morning. But still a little bit lower than where you've been in the market buying this year. So just wanted to confirm that, given the extra free cash flow here in 2019 that the NCIB is still attractive in your view from a capital allocation standpoint?
Todd Stack -- Chief Financial Officer
No, you're absolutely right. It is an attractive price and as I mentioned in the -- earlier in the call, we plan to be back in the market here in Q4, as soon as we're out of blackout.
Patrick Kenny -- National Bank Financial -- Analyst
Okay, great. Thanks, guys.
Dawn Farrell -- Corporation Chief Executive Officer and Corporate Director
Thank you.

[Operator Instructions] Your next question comes from John Mould with TD Securities. Your line is open.
John Mould -- TD Securities -- Analyst
Good morning. Maybe starting with the SemCAMS co-gen project, it's shown as a potential dropdown to RNW new deck. It's fully contracted on steam and I think half contracted on electricity. So does TransAlta Corp potentially take on that merchant risk in a dropdown scenario? Or are you comfortable with the co-gen going to RNW with some level of merchant exposure?
Brett M. Gellner -- Chief Development Officer
Yeah. John, we've -- as you can imagine, we've had some kind of early discussions with the Board of TransAlta Renewables. So they understand the project that there is a bit of a merchant component to it. And in general, we prefer fully contracted assets at the TransAlta Renewables level. But I wouldn't rule out the notion that having a modest bit. In a context of the whole portfolio of merchant power being available to -- being accepted by TransAlta Renewables, given TransAlta Corporation's ability to manage and dispatch that into the market, is likely OK.
John Mould -- TD Securities -- Analyst
Okay. And then just on the Shell PPA. I appreciate you don't want to detail individual contracts. But just more broadly speaking, what's the minimum contract length you need to characterize an agreement as long-term?
Dawn Farrell -- Corporation Chief Executive Officer and Corporate Director
It should be -- so, I would say, a medium-term contract is five years and anything longer than that is long-term.
John Mould -- TD Securities -- Analyst
Okay. That's helpful. And then just lastly on the US coal results in the quarter, I know in your remarks you're pointed pointed to strong unit availability. Can you just give a little more color on what drove that big gross margin increase in the quarter?
Todd Stack -- Chief Financial Officer
Sorry, I missed. Can you just repeat your question?
Dawn Farrell -- Corporation Chief Executive Officer and Corporate Director
The US results in the quarter was much better than -- Yeah. US results. So, in last year we had a lot more unplanned outages. And so, even though prices were high last year the plant wasn't available to take advantage of high prices. This year, we saw strong pricing in around the CAD30 level and the plant had great availability in the quarter and really was able to capture those prices. Yeah. I would say, if you look at Centralia, and you look at our trading business, our trading business -- we have a lot of real-time traders and they arbitrage and they move power from the north to the -- to California. And this year has this volatility that's occurred because of all the renewables in the California market that have to be backed up has benefited both Centralia, and the trading business because they're chipping away every day and moving power all over the place. So that's been very helpful.
I think as you look ahead, we know that unit 1 comes off at the end of 2020, plus you've got a bunch of coal plants coming off in that region that all have been supplying base load power that has been sort of a nice complement to the hydro in the Pacific Northwest. I just think that there is a lot more volatility coming forward as we look at those markets. So, we're starting to see for the first time some actual uplift as a result of that.
Brett M. Gellner -- Chief Development Officer
Yeah. But, John, specific to Todd's point, the specific answer was the amount of purchase power we had in Q3 of 2018 was significantly higher than it was in 2019. So we were able to supply a lot more, so we made it as opposed to having to buy in the marketplace. That's probably the biggest driver between the results quarter-over-quarter effectively on the comparative quarter basis.
John Mould -- TD Securities -- Analyst
Okay. Thanks for all that color. Those are all my questions. Thanks very much.
Dawn Farrell -- Corporation Chief Executive Officer and Corporate Director
Thanks, John.

Your next question comes from Chris Varcoe from Calgary Herald. Your line is open.
Chris Varcoe -- Calgary Herald -- Analyst
Hi. My apologies, if this question has already been asked. But I'm curious, Dawn, If you could tell me what are your thoughts on the government's new TIER program, and more specifically how it's going to affect the Company going forward?
Dawn Farrell -- Corporation Chief Executive Officer and Corporate Director
Yeah. I mean, I thought the TIER program was well -- first of all, it was expected and I think it's a good program kind of overall because what it does is it enables companies like ours to make decisions like the ones that we've been making. There is a price on carbon, but there is also our performance standard. That performance standard is incredibly important for us in terms of our the -- already existing renewables investments and also important in terms of making our coal-to-gas transition. So it's a good program. I'm really hoping really hoping that it stays stable as we go forward, in terms of the performance standard. And I think the world is moving toward carbon being priced and we're ahead of the game here and we need to get credit for that.
Chris Varcoe -- Calgary Herald -- Analyst
Can I ask you, what do you expect the financial implications will be in 2020 versus 2018 or 2019? In other words, will you be paying more or less or the same under the program? And just to follow-up on a completely different issue, can I ask you what your outlook is on the electricity pricing in Alberta in 2020?
Dawn Farrell -- Corporation Chief Executive Officer and Corporate Director
Yeah. So the -- it is the same, because it was expected to be CAD30 and 0.37 performance standard. So there is no --
Todd Stack -- Chief Financial Officer
Which is the same standard in price that's currently in the market today.
Dawn Farrell -- Corporation Chief Executive Officer and Corporate Director
Yeah. Same standard of price for the market, expected that. And then I -- the current forward price for electricity in 2020 is around --
Todd Stack -- Chief Financial Officer
In the CAD55 to CAD60.
Dawn Farrell -- Corporation Chief Executive Officer and Corporate Director
CAD55 to CAD60, which has been -- if you look back over the last 20 years, on average, Alberta trades in that sort of CAD60 -- CAD55 to CAD60 range. So it's a great price for consumers.
