Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Shares of demand response company EnerNOC (Nasdaq: ENOC) jumped 23% today after the company forecast revenue from PJM.

So what: The power grid operated by PJM Interconnection is expected to account for $275 million in revenue in 2014 based on company expectations. The company had a total of $280 million in revenue during 2010, so that's a big boost for the company.

Now what: Two months ago the Federal Energy Regulatory Commission made a ruling that "negawatts" -- the demand response EnerNOC and Comverge (Nasdaq: COMV) provide -- were to be treated the same as megawatts, giving way to a boost in PJM revenue. Now that we have an idea what EnerNOC is expecting from this clarification, it gives investors reason to bet EnerNOC can be consistently profitable. Motley Fool Hidden Gems has been all over the case on EnerNOC, betting that the PJM ruling would give the company a boost -- and they appear to be right.
