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.

California ISO Declares a Stage 3 Alert – No Outages Yet
LCG, Jan. 16, 2001The California Independent System Operator, still struggling to come up with enough power to meet a forecast demand of 32,315 megawatts in its control area, declared a Stage 3 Electricity Emergency at 7:20 this morning, pacific time.The ISO said that a total of 10,700 megawatts of generation was off line because of planned maintenance or forced outages. The 1,190 megawatt San Onofre Unit 3 nuclear power plant was among that, having shut down for refueling. Another 1,600 megawatts worth of generation tripped off line over the weekend when something broke.On the best day in spring, with all plants operating and the state's rivers in full flow, Cal-ISO would have a little more than 44,000 megawatts of power at its disposal. That is a far cry from the 53,000 megawatts of generating capacity some state officials say the state has.The discrepancy is the one that accompanies comparisons of apples with oranges. Cal-ISO is responsible only for that portion of the transmission network owned by the state's three investor-owned utilities. The ISO can draw on the power generated only by plants owned by those utilities or the ones sold by them to independent power producers.The state officials, on the other hand, look at total in-state generation, which includes power generated in plants owned by municipal utilities, irrigation districts and rural electric cooperatives. The last time we looked, the Los Angeles Department of Water and Power, a municipal utility, owned about 6,500 megawatts of capacity.Today, about 33,000 megawatts are available to Cal-ISO, and Cal-ISO is going to need all of it.
