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.

California PUC Issues Proposed Decision on Energy Storage Systems
LCG, September 5, 2013--California Public Utility Commissioner Carla Peterman issued a proposed decision earlier this week that establishes the policies and mechanisms for procurement of electric energy storage pursuant to Assembly Bill 2514, which was signed by then California Governor Arnold Schwarzenegger nearly three years ago.
The proposed decision establishes a target of 1,325 MW of energy storage to be procured by Pacific Gas and Electric Company (PG&E), Southern California Edison Company (SCE) and San Diego Gas & Electric Company (SDG&E) by 2020 and sets a schedule for solicitation of energy storage. The decision directs these utilities to file separate applications containing a proposal for their first energy storage solicitation by January 1, 2014.
In addition to placing requirements on California's investor owned utilities (IOUs), the decision further directs community choice aggregators to procure energy storage equal to one percent of their annual peak load by 2020 and that electric service providers procure energy storage equal to one percent of their annual peak load by 2016.
The objectives for energy storage development were stated in Assembly Bill 2514 as follows, "Energy storage has the potential to transform how the California electric system is conceived, designed, and operated. In so doing, energy storage has the potential to offer services needed as California seeks to maximize the value of its generation and transmission investments: optimizing the grid to avoid or defer investments in new fossil-power plants, integrating renewable power, and minimizing greenhouse emissions."
The outlook for pumped storage projects is somewhat constrained by the proposed decision. Findings of fact included: (i) that the majority of pumped storage projects are 500 MW or over, (ii) that a single pumped storage project could account for the entire procurement target within a utility territory, and (iii) the sheer size of a large-scale pumped storage project would dwarf other smaller, emerging technologies and could inhibit the fulfillment of market transformation goals.
With respect to conclusions of law, the decision states that it is reasonable to exclude pumped storage projects 50 MW and over from participating in the Energy Storage Procurement Framework and Design Program.
