Virginia, US-based utility company Dominion Energy has teamed up with Vanguard Renewables on a nationwide partnership to dairy waste into renewable natural gas.

The $200 million (€179.6 million) partnership will see Dominion Energy owning numerous projects currently under development in the US states of Georgia, Nevada, Colorado, New Mexico and Utah, as well as market the gas. Vanguard Renewables’ subsidiary Clean Energy Investment USA will design, develop and operate the projects.

Diane Leopold, co-chief operating officer of Dominion Energy, said: “Through our strategic partnership with Vanguard Renewables and our strategic alliance with Dairy Farmers of America, we’re rapidly accelerating the development of these transformational projects and for the first time on a nationwide scale. The environmental, consumer and agricultural benefits of these projects are truly groundbreaking.

“We’re substantially reducing greenhouse gas emissions from US dairy farms, delivering new sources of clean energy to US consumers and providing a new source of long-term revenue for family farmers across the country.”

Dominion Energy previously announced a $500 million (€449 million) venture in partnership with Smithfield Foods to capture methane from pig farms and convert it to renewable natural gas (RNG). Dominion Energy and Vanguard Renewables’ partnership will reduce annual carbon dioxide equivalent emissions by more than 450,000 metric tonnes, the same as taking approximately 100,000 cars off the road or planting almost 7.5 million new trees every year.
