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.

Permit for Proposed Biomass Plant in New Mexico to be Reconsidered
LCG, August 8, 2007--The New Mexico Secretary of Environment in late May denied a permit to a proposed power plant fueled by biomass due to the planned use of natural gas as a start-up fuel. Plant start-ups would likely occur once per year for up to eight hours, according to the developer, Western Water and Power Production. Western Water and Power Production filed an appeal with the Environmental Improvement Board, and a hearing is scheduled for August 20.
As stated in the final order, "The plant will burn natural gas for up to 8 hours each time it starts up. Natural gas is a fossil fuel, and thus the plant appears to be a listed PSD source under 20.2.74.501.F, fossil fuel boilers (or combinations thereof) totaling more than 250 million BTU/hr heat input; and 20.2.74.7.AF, ?major stationary source,? as a stationary source listed in Section 501 that emits or has the potential to emit emissions equal to or greater than 100 tons per year of any regulated new source review pollutant."
The New Mexico Environment Department Air Quality Bureau supported the
issuance of the permit with conditions necessary to protect public health and welfare and the environment.
The planned electric generating capacity of the biomass facility is 35 MW, and the plant would operate as a base-load facility. The proposed electric generating facility would be located in Torrance County adjacent to Tagawa Greenhouses, which would use waste heat from the power plant to heat greenhouses.
On July 31, 2006, Western Water and Power Production and PNM, an electric utility in New Mexico, announced that they had executed a 20-year power purchase agreement (PPA) for the delivery of renewable energy from the biomass plant.
Under state law, New Mexico electric utilities must produce or purchase at least 10 percent of their customers? electricity requirements from renewable energy resources by 2011. The planned service date for the plant is early 2009.
