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.

AmerenUE Halts Plans for New Reactor at Callaway
LCG, April 24, 2009--AmerenUE yesterday announced its plans to install another nuclear reactor at the Callaway Plant in Missouri are now on hold, as state legislative changes desired by the utility are not proceeding as expected.
AmerenUE was relying upon legislative changes that would allow for a utility to recover project costs from consumers prior to project completion and start-up. Without the change in the law, and given the current credit-constrained markets, AmerenUE stated that it believes getting financial backing for the multi-billion dollar project is impossible.
The existing Callaway Plant consists of a single reactor that has a net generating capacity of 1,126 MW and began service December 1984. The site is located about twenty-five miles northeast of Jefferson City and was initially developed with the idea of adding a second unit in the future.
In 2007, AmerenUE announced that the company had signed an agreement with UniStar Nuclear Energy to help prepare a combined operating license (COL) application.
AmerenUE submitted a COL application to the Nuclear Regulatory Commission (NRC) on July 28, 2008 to add a second reactor at its Callaway Plant. The application incorporated AREVA's U.S. Evolutionary Power Reactor (EPR), which is a pressurized water reactor with a nominal electric output of approximately 1,600 MW. The NRC accepted the application for review in December 2008.
