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.

Western Energy Partners Announces Plan to Proceed with the 750-MW Clean Path Energy Center

LCG, April 10, 2015-Western Energy Partners, LLC announced earlier this week its plan to develop, permit, construct and operate the Clean Path Energy Center in New Mexico. The energy center will include both a 680-MW natural gas-fired facility and a 70-MW solar photovoltaic (PV) facility. The project is scheduled to be completed in mid-2019. SNC-Lavalin Inc. will serve as the Engineering, Construction and Procurement (EPC) contractor for the gas-fired, combined cycle power block and support project development.

"The Clean Path Energy Center is ideally located to take full advantage of the robust natural gas and electrical infrastructure in San Juan County. This uniquely configured project will feature unprecedented operating efficiencies, exceptionally fast ramping rates and will establish new standards for environmental stewardship. Further, the Clean Path Energy Center is ideally positioned to meet the future electrical needs of consumers in a highly economic and sustainable manner for many years to come," said the president of Western Energy Partners.

The Clean Path Energy Center will be constructed in the Four Corners area on a 635-acre, privately-owned land parcel. The combined cycle plant will employ an innovative hybrid air and water cooling system to minimize water use. The plant will connect to the electrical transmission grid at the nearby Shiprock Substation, which is operated by the Western Area Power Administration (Western), via a new transmission line that will be less than two miles in total length. Natural gas will be delivered by connecting to the San Juan Hub through existing pipelines owned by the El Paso Natural Gas Company.

The plant will partially offset jobs, revenues, and generation lost when Arizona Public Service (APS) shuttered three units at a nearby coal plant and Public Service Company of New Mexico (PSNM) shuttered two units at another.

The president of Western Energy Partners stated, "The Clean Path Energy Center project is designed to take full advantage of the recent and dramatic technological advances in modern gas turbine and solar PV technologies. The 680 MW combined cycle plant will be capable of providing baseload generation around the clock in an exceptionally efficient and flexible manner, thereby enhancing the viability of intermittent renewable technology in the region. Additionally, the renewable 70 MW Solar PV power block will be capable of providing additional renewable peaking generation capacity that is critical during times of higher system loads."
