A 4.2-MW power plant at the Nelson Gardens landfill in Southwest San Antonio began commercial operations on April 1 and it is supplying power to CPS Energy, said the municipal utility in an April 24 blog post.
CPS Energy signed a 15-year agreement with Nelson Gardens Energy of Liverpool, N.Y., to purchase the power from the facility.
The landfill gas-to-electricity plant concept is not new to the energy industry, or to CPS Energy, the blog post noted. Customers began receiving power from the Covel landfill plant in 2005. Located adjacent to Nelson Gardens, that older plant generates 9.6 MW.
In addition to 13.8 MW of power from landfills, CPS Energy has contracts in place for more than 444 MW of solar and 1,059 MW of wind energy.
