Four 20-cycle gas engines inside JBER's Landfill Gas Waste to Energy Plant, adjacent to the Anchorage Municipal Landfill. The plant burns methane from the landfill, supplying about half of Ft. Richardson's energy needs. The landfill has been more productive than initially expected, so the plant is accelerating their installation of a fifth engine. April 30, 2013

A new power plant fueled by methane from Anchorage's landfill supplies 25 percent of Joint Base Elmendorf Richardson's electricity. The $30 million plant built by Doyon Utilities, which is contracting with JBER, is exceeding expectations.

The plant is in the process of installing a fifth generator, an addition that wasn't expected for another five years. Instead, the plant was ready for the fifth generator after just eight months of operation because the Anchorage landfill produced more methane than expected.
