LCG, December 18, 2025--RWE and Indiana Michigan Power Company (I&M), an American Electric Power (AEP) company, today announced their partnering to provide new wind power generation capacity online to meet Indiana’s growing electricity demand. The companies signed a 15-year power purchase agreement (PPA) for the total output from RWE’s 200 MW Prairie Creek wind project in Blackford County, Indiana. I&M will purchase electricity from the wind project, which will further diversify its portfolio and be consistent with its all-of-the-above strategy to secure generation for its rapidly growing electricity demand.

LCG, December 16, 2025--The Nuclear Regulatory Commission (NRC) announced today that it has renewed the operating licenses of Constellation LLC’s Clinton Unit 1 in Clinton, Illinois, and Dresden Units 2 and 3, near Morris, Illinois, for an additional 20 years beyond the current expiration dates. The combined capacity of these three, Illinois-based nuclear units is 2,925 MW, and the operating license extension will enable the units to generate carbon-free power through about 2050.

MISO Requests FERC Assistance for Grid Reliability in Response to EPA Rules
LCG, December 1, 2011--The Midwest Independent Transmission System Operator, Inc. (?MISO?) Vice President of Transmission Asset Management yesterday warned the Federal Energy Regulatory Commission (FERC) that the proposed Environmental Protection Agency (EPA) air emission rules pose threats to power reliability.
In comments submitted for FERC's technical conference this week on reliability risks related to compliance with new EPA air emissions regulations, the Vice President stated that proposed regulations will require simultaneous generator outages that may jeopardize electric reliability in the Midwest.
The concerns focus on the 2014/2015 compliance deadline for the EPA's proposed mercury rule, which provides limited time for the installation of new emission control equipment or capacity replacement. To comply, generation owners must remove units from service simultaneously, which will provide inadequate generation resources to sustain reliable electricity supply. "As a result, 62,000 MW of coal units could potentially be unavailable for reliability purposes - all at the same time."
The MISO submittal also stated a lack of confidence that there will be sufficient allowances available via the CSAPR allowance trading, which may result in decisions to limit operations by some of the generation fleet. "This may result in potential transmission reliability concerns that would normally be mitigated through market
redispatch that may no longer be available if unit owners adjust their bidding strategies or availability to meet CSAPR limitations." Other concerns include accelerated unit retirements, coupled with delays in transmission improvements, could result in inadequate grid reliability.
In a separate filed response to questions from FERC Commissioner Philip D. Moeller, the MISO requested the Commission to direct regional transmission organizations to work together to ensure that physically available transfer capability across regions is accessible to those who need and can provide excess power. The filing states, "The pending EPA regulations and potential impact on generator operations highlights the need for coordinated planning between generator owners and market transmission providers."
