LCG, July 30, 2025--Peak Energy today announced the launch and shipment of its sodium-ion battery energy storage system (BESS) that includes a patent-pending passive cooling design that should significantly reduce lifetime energy costs. Peak Energy's system is to be deployed this summer in a shared pilot project with nine utility and independent power producer (IPP) customers.

LCG, July 29, 2025--The Tennessee Valley Authority (TVA) today reported third quarter fiscal year 2025 financial results, including $9.8 billion in total operating revenues on 121 billion kilowatt-hours of electricity sales for the nine months ending June 30, 2025. TVA reported total operating revenues had increased 11 percent over the same period last year, primarily due to higher rates and sales. TVA presented that sales of electricity increased 3 percent compared to the same period last year, primarily due to higher sales to residential and small customers, as well as increases within the data processing, hosting, and related services sector.

Dominion Plans on Offshore Wind Projects, Pumped Storage and Relicensing of Nuclear Plants to Reduce Carbon Emissions
LCG, August 1, 2019--Dominion Energy presented plans to invest in clean energy infrastructure in its second-quarter earnings call yesterday. Dominion's five-year growth capital plan totals $26 billion through 2023.
A significant portion of Dominion's capital expenditure plan is to develop and install offshore wind projects. In July Dominion initiated construction on its $300 million, 12-MW Coastal Virginia wind pilot project, located 27 miles offshore of Virginia Beach, Virginia. The project is scheduled for completion in 2020. Dominion now expects the offshore lease area may accommodate over 2,000 MW of generation capacity and a total investment of $1.1 billion through 2024.
The executive vice president, president and CEO of Dominion's Power Generation Group stated, "In Virginia, we're looking at the need to get the life-cycle cost equivalent down closer to maybe the $80/MWh range, which means we need to see about a 15% to 20% capital cost improvement. We think that those costs can move in that direction once we stand up the US supply chain. That's been a real benefit that they've seen in Europe is being able to scale up the supply chain."
Given Dominion's interest to add variable or intermittent renewable generation resources, Dominion is also refining its search for a potential site to install a $2 billion to $3 billion pumped storage facility in southwestern Virginia. In addition, Dominion Energy Virginia (Virginia Electric and Power Company) will file its first battery pilot program this week. "We will pair batteries with solar facilities to begin the integration of peak shifting and clipping as well as test the reliability benefits of batteries on our distribution grid."
Relicensing Dominion's four existing Westinghouse pressurized water reactors reactors in Virginia for another 20 years is another critical element of Dominion's plan to utilize carbon-free electric generating resources. The nuclear resources include the approximately 1,958-MW North Anna and the 1,750-MW Surry nuclear power plants, along with a $4 billion capital program. The North Anna and Surry units were originally licensed to operate for 40 years, like all U.S nuclear units. All four units' licenses were renewed for 20 additional years of operation in 2003. The North Anna and Surry nuclear units' respective licenses currently will expire in 2038 and 2040, and 2032 and 2033. After a second renewal, the respective licenses for North Anna and Surry will allow the units to operate to 2058 and 2060, and 2052 and 2053.
