LCG, September 30, 2025--Vistra Corp. announced yesterday that it will proceed with the next phase of its capital plan to support grid reliability in Texas. In 2024, Vistra identified over $1 billion worth of potential capital additions in generation capacity within the Texas ERCOT market by 2028 if market conditions were supportive. Now, with West Texas' growing power requirements, particularly the state's expanding oil and natural gas industries, Vistra reached a final investment decision and confirms it will build two new advanced natural gas-fired power units on-site at its Permian Basin Power Plant.

PGE Announces Addition of 475 MW of Battery Energy Storage Systems to Improve Grid Reliability and Costs
LCG, August 7, 2025--Portland General Electric (PGE) today announced the completion of three, four-hour lithium-ion utility-scale battery energy storage systems (BESS) in Oregon, adding 475 MW and more than 1.9 GWh of dispatchable capacity to serve the Portland metro area. Each of these BESS facilities can deliver power during peak demand or when other electric generating facilities are limited, which improves system flexibility, reliability and costs.
These three BESS facilities are strategically located at key substations in North Portland, Troutdale and Hillsboro, where they are integrated into PGE's system to better align the electric supply and demand on the grid on an hourly and daily basis. Battery storage reduces PGE's reliance on expensive short-term electricity purchases, helping stabilize energy costs, limit price volatility for customers, and support the integration of intermittent sources such as wind and solar power generation facilities.
"Batteries play an important role in helping PGE build a more flexible, reliable and diverse generation portfolio," said PGE's Senior Director of Energy Supply. "In addition to providing power during peak hours every day, batteries enhance our ability to respond to sudden changes in the grid and help keep energy supply and demand balanced. For customers, that means more stable and reliable power, all at the lowest possible cost."
Two of the BESS facilities were successfully developed and awarded to Eolian, L.P. (Eolian) through PGE's 2021 All-Source Request for Proposals (RFP) process. The first is Sundial, a 200-MW facility in Troutdale that was developed by Eolian and operated by NextEra Energy Resources under a 20-year storage capacity agreement with PGE. The facility achieved commercial operation in December 2024. The second is Seaside, a 200-MW PGE-owned facility located in North Portland and delivered to PGE by Eolian under a fixed-cost, Build-Transfer Agreement (BTA). The facility achieved commercial operation in July 2025.
The third BESS facility is Constable, a 75-MW PGE-owned facility located in Hillsboro and constructed for PGE under an engineering, procurement and construction (EPC) agreement with Mortenson. The facility achieved commercial operation in December 2024.
Eolian's CEO stated, "Battery energy storage systems sited at major substations radically improve the use of existing high voltage transmission lines, avoiding expensive or challenging new grid upgrades and providing a low-cost load growth solution through existing infrastructure."
PGE also completed the 17-MW Coffee Creek BESS facility near Wilsonville in 2024. The completion of Seaside, Sundial, Constable and Coffee Creek brings PGE's large-scale battery storage capacity to 492 MW.
