LCG, October 28, 2025--NextEra Energy and Google yesterday announced two agreements that will help meet growing electricity demand from artificial intelligence (AI) with clean, reliable, 24/7 nuclear power and strengthen the nation's nuclear leadership. First, Google signed a new, 25-year agreement for power generated at the Duane Arnold Energy Center, Iowa's only nuclear power facility. The 601-MW boiling water reactor unit was shut down in 2020 and is expected to commence operations by the first quarter of 2029, pending regulatory approvals to restart the plant.

LCG, October 23, 2025--Google announced today a first-of-its kind agreement to support a natural gas-fired power plant with carbon capture and storage (CCS). The 400-MW Broadwing Energy power project, located in Decatur, Illinois, will capture and permanently store its carbon dioxide (CO2) emissions. By agreeing to buy most of the power it generates, Google is helping get this new, baseload power source built and connected to the regional grid that supports our data centers.

Gemma Power Systems Receives Notice to Proceed on a 1.2-GW Power Project in Texas
LCG, April 8, 2025--Gemma Power Systems (“Gemma”), a wholly owned subsidiary of Argan, Inc. (“Argan”), has received a notice to proceed on its previously announced engineering, procurement and construction (“EPC”) services contract with Sandow Lakes Energy Company, LLC (“SLEC”) for a 1.2-GW power plant in Lee County, Texas. Construction of the natural gas-fired, combined cycle facility is scheduled to commence this summer, with an expected project completion date in 2028.
SLEC announced its plans to build the new electric generating facility earlier this year. The combined cycle facility will be developed and owned by a SLEC subsidiary and will operate within the Electric Reliability Council of Texas (“ERCOT”). The 1,200-MW project is located near a 24-inch tap off the Matterhorn Natural Gas Pipeline, and the new facility will add significant dispatchable generating capacity to the region.
Gemma's CEO stated, “We’re thrilled to move forward with SLEC on this major power project. Their strong development efforts set the stage for success, and we look forward to working together. Expanding power infrastructure is essential to meeting rising energy demands, and our team is dedicated to delivering exceptional results.”
SLEC previously executed an agreement with Siemens Energy to reserve manufacturing slots for two SGT6-9000HL gas turbines to be installed at the new combined cycle facility. The SGT6-9000HL is one of the most technologically advanced gas turbines in the world, featuring high power output, excellent fuel efficiency, and the capability of operating on hydrogen with only minor modifications to the equipment.
The Sandow Lakes project location was formerly the site of a 1950s-era integrated industrial enterprise that included 1,200-MW of coal-fired generating capacity. The legacy coal facilities and industrial facilities are in the process of being partially demolished and repurposed, paving the way for the clean-burning, natural gas-fired facility. Texas State Representative Stan Gerdes, in whose House District the development sits, previously commented, “For the citizens of this region, losing Alcoa after 6 decades of manufacturing was a blow to the entire region. But with the advent of Sandow Lakes, the folks living here have renewed enthusiasm for the area, their families and for the future.”
