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.

PG&E Announces Proposal to Close Diablo Canyon Nuclear Power Plant by 2025
LCG, June 22, 2016--PG&E yesterday announced a Joint Proposal with labor and environmental organizations that would increase investment in energy efficiency, renewables and storage beyond current state mandates while phasing out PG&E's production of nuclear power in California by 2025. The Joint Proposal would replace power produced by two nuclear reactors at the Diablo Canyon Power Plant with energy efficiency, renewables and energy storage. The Joint Proposal includes a PG&E voluntary commitment to a 55 percent renewable energy target in 2031.
Diablo Canyon Power Plant (DCPP) is located along the Pacific coast north of Santa Barbara and has operated safely since 1985 generating greenhouse gas free (GHG-free) electricity. The two Westinghouse Pressurized Water Reactor (PWR) units at the site have a combined electric generating capacity of approximately 2,240-MW and are licensed until 2024 and 2025, respectively. PG&E applied in November 2009 to the Nuclear Regulatory Commission (NRC) for 20-year license renewal extensions for both reactors.
PG&E Corporation's Chairman, CEO and President stated, "California's energy landscape is changing dramatically with energy efficiency, renewables and storage being central to the state's energy policy. As we make this transition, Diablo Canyon's full output will no longer be required. As a result, we will not seek to relicense the facility beyond 2025 pending approval of the joint energy proposal. Importantly, this proposal recognizes the value of GHG-free nuclear power as an important bridge strategy to help ensure that power remains affordable and reliable and that we do not increase the use of fossil fuels while supporting California's vision for the future."
PG&E Corporation's Chairman added, "Supporting this is a coalition of labor and environmental partners with some diverse points of view. We came to this agreement with some different perspectives-and we continue to have some different perspectives-but the important thing is that we ultimately got to a shared point of view about the most appropriate and responsible path forward with respect to Diablo Canyon and how best to support the state's energy vision."
The parties to the Joint Proposal are PG&E, International Brotherhood of Electrical Workers Local 1245, Coalition of California Utility Employees, Friends of the Earth, Natural Resources Defense Council, Environment California and Alliance for Nuclear Responsibility.
Under the terms of this Joint Proposal, PG&E will retire Diablo Canyon at the expiration of its current NRC operating licenses, and the parties will jointly propose and support the orderly replacement of Diablo Canyon with GHG-free resources prior to the retirement of the nuclear facility. In addition, PG&E will stop any efforts on its part to renew the Diablo Canyon operating licenses and will ask the NRC to suspend consideration of the pending Diablo Canyon license renewal application pending withdrawal with prejudice of the NRC application upon California Public Utilities Commission (CPUC) approval of the Joint Proposal Application.
PG&E stated in its announcement that it does not believe customer rates will increase as a result of the Joint Proposal because it believes it is likely that implementing the proposal will have a lower overall cost than relicensing DCPP and operating it through 2044. Factors affecting this include, in addition to lower demand, declining costs for renewable power and the potential for higher renewable integration costs if DCPP is relicensed.
The Joint Proposal is also contingent on a number of regulatory actions.
California's other nuclear facility, Southern California Edison's San Onofre Nuclear Generating Station (SONGS), was closed in 2013 and is transitioning into the initial stages of preparation to be decommissioned after the failure of replacement steam generators.
