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.

LCG, September 4, 2025--Puget Sound Energy (PSE) announced yesterday that phased construction has commenced on its 142-MW Appaloosa Solar Project, a utility-scale solar facility underway in southeastern Washington. The project is being built by Qcells EPC, who will serve as the module manufacturer and the engineering, procurement, and construction (EPC) solution provider. Construction is scheduled through 2026, and commercial operation is expected at the end of next year.

Indiana Commission Authorizes Duke IGCC Project
LCG, November 21, 2007--Duke Energy yesterday received authorization from the Indiana Utility Regulatory Commission to proceed with the construction of a 630-MW coal-fired power plant that will use an advanced, integrated gasification combined cycle (IGCC) technology. Duke must still receive an air permit from the Indiana Department of Environmental Management. If received, construction may commence in 2008, with full operations achieved in early 2012.
The proposed project will be built at Duke's existing Edwardsport Generating Station near Vincennes, Indiana. Once the new plant is operational, the old facilities, which include coal and oil units that have a capacity of 160-MW, would be retired.
The IGCC design employed for the plant includes coal gasification. Synthetic gas created from coal is used in a gas turbine to generate electricity. The hot exhaust gas from the turbine heats water to produce steam to power a steam turbine and generate electricity a second time. The gasification process offers the potential for lower cost solutions to capture and sequester CO2, which may assist in efforts to thwart global warming.
The estimated cost of the plant is roughly $2 billion, which will be offset by over $460 million in local, state and federal tax incentives.
Duke filed an application for a "Certificate of Public Convenience and Necessity" (CPCN) with the Commission to build the plant in September 2006. Duke must justify and seek approval in a separate proceeding to recover any costs above the approved $1.985 billion.
The Commission directed Duke to proceed with its plans to develop carbon capture and storage studies and to file a proceeding with the Commission to establish that process in six months.
