LCG, September 12, 2025--Entergy announced yesterday that the Public Utility Commission of Texas (PUCT) approved Entergy Texas’ proposal to build two efficient natural gas-fired power plants to support the region’s rapid growth. The combined electric generating capacity of the two facilities, the Legend Power Station and the Lone Star Power Station, will add over 1,200 MW to the Southeast Texas power grid to support new customer demand, increase reliability and lower costs for all customers. Both facilities are scheduled to commence operations by mid-2028.

Regulatory Proceeding Commence for New Coal-fired Power Plants in Nevada
LCG, August 25, 2006--Regulatory hearings at the Nevada Public Utilities Commission (PUC) have started for Sierra Pacific Resources' proposed Ely Energy Center. The project was announced last February and it includes the construction of two, 750-MW, coal-fired power generating units in eastern Nevada plus a new, 250-mile long transmission line that would connect Nevada's northern and southern regions. The estimated, overall project cost is $3.7 billion.
The new units, to be located in White Pine County, would use traditional, pulverized coal technology, together with state-of-the-art emission control technologies. Given timely regulatory approval, the first unit is scheduled to commence service in 2011, with the second unit to follow in 2013. The new generation and transmission facilities are key elements of the Integrated Resource Plans of Nevada Power Company and Sierra Pacific Power Company, both subsidiaries of Sierra Pacific Resources.
The regulatory hearings have drawn interest from an independent power producer, LS Power, that has already developed its own Nevada project that includes a coal-fired, electric generating station with a capacity of 1,600-MW, as well as a 250-mile transmission line. The PUC issued a decision not to let the LS Power present testimony regarding the generating facilities; however, the PUC did allow for LS Power to take part with respect to the transmission line. LS Power has filed a petition for reconsideration.
Sierra Pacific Resources' principal subsidiaries are Nevada Power Company, the electric utility serving much of southern Nevada, and Sierra Pacific Power Company, which serves most of northern Nevada, together with customers in California in the vicinity of Lake Tahoe.
