Utilities that operate nuclear generation facilities have been hurt by pricing pressures created during the downturn in natural gas prices. As is evident in Exelon's (NYSE:EXC) latest release, these pressures still exist. As a generator of base load energy, Exelon has found itself battling the likes of natural gas, solar, and wind power as all three forms continue to expand their reach within the nuclear segment. This triumvirate has caused a depression in the prices that Exelon is able to charge customers.
Friday will bring a direct comparison to Exelon when Duke Energy (NYSE:DUK) reports, as it is the largest utility in the country and has a large nuclear presence in the Southeast. I expect that some margin pressure will be felt, but continued benefits from its own merger with Progress Energy should provide similar tailwinds as those Exelon experienced.
