Eklutna, Alaska

Eklutna Generation Station

Palmer, Alaska, USA

171 MW

Palmer, a town some 40 miles northeast of Anchorage, Alaska, recently showcased the pioneering spirit of its namesake entrepreneurial founder George W. Palmer, as the cooperative utility headquartered there, Matanuska Electric Association (MEA), departed from conventional practice and decided to build its own power plant. For its clients in the Alaskan Railbelt this meant greatly reducing the costs of its supplied energy. The partner of choice for such an endeavour, providing the engineering, generating equipment and auxiliary appliances of the power plant, was Wärtsilä.

In the event of a natural disaster such as an earthquake, these engines can switch fuels without a hiccup.
