Oklo and Siemens Energy Sign Agreement to Accelerate Power Conversion System for New SMR in Idaho

LCG, November 19, 2025--Oklo Inc. and Siemens Energy announced today that the parties have signed a binding contract for the design and delivery of the power conversion system for Oklo’s Aurora-INL (Idaho National Laboratory) nuclear small modular reactor (SMR). The agreement authorizes Siemens Energy to begin engineering and design work to expedite procurement of long-lead components and to initiate the manufacturing process for the power conversion system. Oklo’s expertise in advanced fission technology will be combined with Siemens Energy’s extensive industry experience with steam turbine and generator systems, with the ultimate goal of generating carbon-free, reliable electricity.

NERC's New Winter Reliability Assessment Raises Concerns for Elevated Risk of Insufficient Supplies to Meet Demand in Extreme Operating Conditions

LCG, November 19, 2025--NERC yesterday released its 2025–2026 Winter Reliability Assessment (WRA), which concludes "much of North America is again at an elevated risk of having insufficient energy supplies to meet demand in extreme operating conditions." The WRA does state that resources are adequate for normal winter peak demand, but extended, wide-area cold snaps will be challenging.

Second Unit at Mountainview Project Commences Operations

LCG, January 27, 2006--Southern California Edison (SCE) announced that commercial operations commenced on January 19 at the second of two gas-fired, electric generating units at the Mountainview Project, located in Redlands, California. The first unit began commercial operations in early December 2005.

The Mountainview Station now provides an additional 1,054 MW of generating capacity to the Southern California electric grid. The new capacity is especially timely, as SCE closed the 1,580-MW, coal-fired Mohave Generating Station in Nevada at the end of last year. According to SCE, the Mohave Generating Station will remain closed for at least four years.

The Mountainview Station is a combined cycle plant consists of two units, each with a capacity of 527 MW. Each new unit includes two combustion turbine generators, two heat recovery steam generators, and one steam turbine generator. Two older units at the station have been mothballed.

Plant construction was started by AES in 2001. California's energy crisis led to a halt in construction. InterGen, a Bechtel-Shell joint venture, purchased the project in March 2003. SCE exercised an option to purchase the partially completed plant in March of 2004, and the construction project was completed by Bechtel.
