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.

PJM Acts to Establish National Interest Electric Transmission Corridors
LCG, March 9, 2006--PJM Interconnection, LLC (PJM) earlier this week filed a request with the Department of Energy (DOE) to designate two electrical paths as National Interest Electric Transmission Corridors (NIETC). If the designation is provided by the DOE, it is expected that a more timely solution can be implemented to reduce transmission congestion and related costs, as well as improve grid reliability.
One high-voltage, transmission corridor targeted is the Allegheny Mountain path, which connects electric generation resources west of the Allegheny Mountains in West Virginia and the Ohio and Kanawha River valleys with load centers in the metropolitan areas of Washington, D.C. and Baltimore.
The second high-voltage, transmission corridor targeted is the Delaware River path, which links electric generation resources west of the Allegheny Mountains in western Pennsylvania, West Virginia and the Ohio and Kanawha River valleys with load centers in the metropolitan areas Philadelphia, Wilmington, Newark and northern New Jersey, and exports to New York City as well.
Last week Allegheny Energy proposed building a $1.4 billion, 330-mile, 500-kV transmission line that would utilize the Allegheny Mountain path. Allegheny stated the first segment is scheduled to be operational in 2013.AEP filed in February plans with the Federal Energy Regulatory Commission (FERC) to use the Delaware River path to build an electric "superhighway." The proposed 550-mile long, AEP Interstate Project is estimated to cost $3 billion and is scheduled to commence operations in 2014.
AEP and Allegheny Energy requested the DOE to designate their proposed lines as NIETC projects, as the Energy Policy Act of 2005 provides for NIETC designation for areas that are experiencing electric energy transmission capacity constraints or congestion that adversely affects consumers. Both companies also filed plans with PJM to build their projects. PJM will consider these and other proposals through its Regional Transmission Planning process. The two proposals - which when combined would extend nearly 900 miles and would cost roughly $4.4 billion - will be also evaluated by a number of other regulatory agencies in multiple states. If NIETC designation is granted, then greater federal pressure may be applied to expedite the process.
