LCG, August 27, 2026--Entergy announced today that new revenues from Mississippi data centers are a primary reason why Entergy Mississippi customers will not see their electricity rates increase this summer. The Mississippi Public Service Commission (MSPC) recently approved a rate plan that keeps Entergy Mississippi’s rates below the national average and prevented what otherwise would have been a $4.87 per month increase in July, compared to June rates. Entergy stated that the elimination of the rate increase is an early example of how data centers are directly benefiting their customers.

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.”
