PUC of Texas Approves Entergy Texas' Plans to Build Over 1,200 MW of Gas-Fired Capacity

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.

Connections of Wind Farms to Irish Grid Blocked

LCG, Dec. 4, 2003--The intermittent nature of wind power production and the significant amount of planned growth of wind installations in Ireland has led a top regulator to halt further connections in order to insure reliable operations.

The decision was prompted in part by a letter to the regulator, Tom Reeves, from the managing director of ESB National Grid, Kieran O'Brien, in which O'Brien asked for emergency steps to be taken. "While these issues could be ignored with low levels of wind generation on the system, now that definitive plans are in place to significantly and rapidly increase the proportion of wind generation on the system, a number of complex technical issues relating to wind generation must be resolved," the letter stated.

Reeves said that he knew the decision would not be received well by executives of wind power production firms. He stated that he was "naturally reluctant to approve emergency type measures of this nature without any prior warning to the industry," but that a higher priority lay in "overall system reliability."

O'Brien asked that the technical issues should be fully researched before any new connections are approved. He wrote that the amount of currently connected facilities and approved wind connection agreements "pose an increased risk to the security and stability of the power system which the transmission system operator feels exceeds the level normally likely to be accepted by a prudent system operator."
