The Trump Administration is expected to scrap the EPA's Clean Power Plan in 2017, which would enable companies to extend the life of coal plants previously slated for closure, according to a report by S&P Capital IQ. Reducing regulations would impact utilities differently, says Christopher Muir, an equity analyst with CFRA. He believes regulated companies with significant coal generation will be winners in 2017, including Black Hills (BKH - Get Report) , Great Plains Energy  (GXP , MDU Resources  (MDU - Get Report) , NiSource (NI - Get Report)  and Vectren (VVC . But according to Muir, companies with unregulated power plants will face market forces that lead to lower power prices. That would negatively affect companies like Exelon (EXC - Get Report) , AES (AES - Get Report) , NextEra Energy (NEE - Get Report) , NRG Energy (NRG - Get Report)  and TransAlta (TAC - Get Report) .
