Dominion Energy has grown its solar fleet in Virginia and North Carolina over the past two years from near zero to nearly 1,350 megawatts in service, in construction or under development — enough to power 340,000 homes during peak sunshine. That makes Dominion sixth among owners of electric utilities, the company said in a press release issued yesterday.
In Virginia, there are 27 solar generating facilities on 4,683 acres, equating to about 444 MW of solar capacity either in operation or under development. Construction of another 300 MW of solar is planned to support a Facebook data center planned in Henrico County. The company’s long-term energy forecast calls for 5,200 megawatts of new solar generation over the next 25 years.
Nationally, parent company Dominion Energy now claims to have the sixth largest fleet of solar facilities in the country. Meanwhile, Appalachian Power, has issued RFPs for up to 10 megawatts of solar production. Virginia’s second-largest utility is leaning more on wind power to build its renewable energy portfolio.
“It’s not just about Dominion Energy meeting its clean energy goals, it’s also about helping our customers achieve theirs,” said Paul Koonce, president and CEO of Dominion Energy’s Power Generation Group. “We have a responsibility to offer the right programs, resources and solutions so our customers can make smart decisions about their energy future, and the key is we’re doing it together.”
Two years ago critics were blasting Dominion Virginia Power for its slow adoption of renewable energy. You don’t hear that much any more. Today foes contend that the utility is interested only in projects that it can own, operate, and generate profits from itself.
Working with solar companies and environmental groups, Dominion cut a “community solar” deal last year in which independent outfits would own and operate the solar farms while Dominion would own the entity that bundled the electricity generation and marketed it to consumers.
Now attacks tend to focus on charges that Dominion discourages development of rooftop solar by individuals and businesses. Virginia, critics say, needs to move to a distributed (more decentralized) grid that can accommodate thousands of small, independent contributors to the grid. A big sticking point is the level of compensation Dominion receives for the critical task of maintaining the transmission and distribution system as well as back-up capacity for when the sun doesn’t shine.
The company says it is seeking State Corporation Commission approval “for a 100 percent renewable energy option for residential and small commercial and industrial customers, as well as an option for business customers to purchase renewable generation equal to a specific portion of their energy usage.”
Dominion also has signaled its intention to modernize the electric grid to make it safer from cyber threats and to accommodate distributed contributors to the grid. “A smart energy grid,” said the press release, “will enable the company to seamlessly connect with cleaner energy resources, including private solar and other local generation sources.”
Ivy Main, who tracks solar energy developments for the Virginia chapter of the Sierra Club, wrote in her blog, Power to the People, that she expects a raft of solar energy bills to be submitted in the 2018 session of the General Assembly. At the top of her list of wants, she would like to end the 1% cap on the amount of energy that can be supplied through net-metered distributed energy and also to remove standby charges on residential solar. She also would like to liberalize power purchase agreements (PPAs) that would allow third parties to structure deals allowing universities, schools, local governments and non-profits to take advantage of solar tax credits.
Main also calls for pilot products to test the concept of microgrids, which are appearing in other states. “Promoting microgrids as one way to keep the lights on for critical facilities and emergency shelters when the larger grid goes down,” she writes. “A microgrid combines energy sources and battery storage to enable certain buildings to ‘island’ themselves and keep the power on. Solar is a valuable component of a microgrid because it doesn’t rely on fuel supplies that can be lost or suffer interruptions.”There are currently no comments highlighted.
