  • Experts: EPA Clean Power Plan’s Legal Uncertainty May Have Lasting Impact

    The Environmental Protection Agency’s (EPA’s) Clean Power Plan will certainly be challenged in court, but states and power companies must expend enormous resources developing and complying with state plans regardless of the outcome, witnesses testified on March 17 at a House hearing on the proposal’s legal and cost issues.  The three-hour-long hearing at the House […]

  • TVA’s Draft Strategy Hints at Future Energy Efficiency Boosts, Coal Retirements

    The Tennessee Valley Authority (TVA) may further reduce its coal-fired capacity and scrap its unfinished Bellefonte nuclear power plant, the utility’s long-awaited draft power generation strategy unveiled on March 9 shows. 
 The federally owned corporation has been developing its 2015 Integrated Resource Plan (IRP), essentially a power planning roadmap to 2033, since fall 2013. The […]

  • FPL Seeks to Acquire and Phase Out Coal-Fired Power Plant

    Florida Power and Light (FPL) wants to buy a 250-MW coal-fired facility in Florida to shut it down. The Juno Beach, Fla.–based company filed a petition with the Florida Public Service Commission (PSC) on Friday requesting approval to acquire the Cedar Bay Generating Plant for $520.5 million. FPL has had a long-term power purchase agreement […]

  • Illinois Mulls Low Carbon Portfolio Standard

    A bipartisan group of Illinois legislators have introduced bills that propose a market-based solution to curb carbon emissions and ensure continued operation of the state’s nuclear power plants. The bills SB 1585 and HB 3293 introduced in the state Senate and House would enact the Illinois Low Carbon Portfolio Standard. That measure, like a renewable […]
