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.

Dominion Notifies NRC of Plan to Relicense Nuclear Units at North Anna Power Station
LCG, November 14, 2017--Dominion Energy Virginia, a unit of Dominion Energy, Inc., yesterday notified the Nuclear Regulatory Commission (NRC) of its intent to relicense its two-unit North Anna Power Station in Louisa County, Virginia for an additional 20-year term. The company informed the NRC that it expects to file a license renewal application in 2020.
Dominion informed the NRC in November 2015 that it would file in the spring of 2019 a similar application to renew the licenses of its two Surry Power Station units, located in Surry County, Virginia.
The North Anna and Surry Power Stations provide at total of 3,568 MW of carbon-free, electric generating capacity. Given the all four licenses are renewed again by the NRC, the respective licenses for North Anna and Surry will allow the units to operate to 2058 and 2060, and 2052 and 2053.
Dominion announced that it is reviewing all technical aspects associated with the renewal of North Anna Power Station's licenses, and while not yet complete, sees no significant barriers that would prevent a license renewal submittal in 2020. The letter of intent is necessary so the NRC can plan its staffing needs to support the license renewal effort. The company expects to invest up to $4 billion on upgrades to North Anna and Surry as part of the relicensing process.
The chief nuclear officer for Dominion's nuclear generation division, stated: "Renewing North Anna Power Station's licenses for a second 20-year period is the right thing to do for our customers, the regional economy and the environment. The planned relicensing of North Anna and Surry ensures that the benefits of these clean energy sources will continue to provide affordable, reliable, carbon-free electricity to our customers through the middle of the century. Our nuclear power stations have proven to be among the most-efficient and most-reliable sources of electricity in our fleet."
"The operation of North Anna and Surry also positions Virginia for economic growth. It directly supports more than 2,000 high-paying jobs in Virginia and produces additional economic and tax benefits. Their continued operation will go a long way toward meeting and maintaining both federal and state goals for lowering carbon emissions in the Commonwealth."
The North Anna Power Station includes two nuclear units that are both three-loop Westinghouse pressurized water reactors. The total station electric net generating capacity is 1,892 MW. Unit 1 began commercial service in 1978 and Unit 2 began commercial service in 1980.
The Surry Power Station also includes two nuclear units with three-loop Westinghouse pressurized water reactors that provide a total electric net generating capacity of 1,676 MW. Unit 1 began commercial service in 1972 and Unit 2 began commercial service in 1973.
Like all U.S. nuclear units, the North Anna and Surry units were originally licensed to operate for 40 years. The licenses for all four units at North Anna and Surry Power Stations were renewed for 20 additional years of operation on March 20, 2003. The North Anna and Surry nuclear units' respective licenses currently will expire in 2038 and 2040, and 2032 and 2033.
Dominion Energy also operates two nuclear units at its Millstone Power Station, located in Waterford, Connecticut. In 2005 the company renewed the station's operating license for one 20-year term, which means the current license for Unit 2 will expire in 2035, and in 2045 for Unit 3. The company may consider another 20-year renewed license for Millstone, but has made no decision to do so at this time.
