Abraham Ellis, manager of Sandia’s Photovoltaic and Distributed Systems Integration Department, testified last week on microgrid technologies before the Senate Energy and Natural Resources Committee at a field hearing in Cordova, Alaska. During the hearing, Ellis provided a perspective on microgrids and hybrid systems.
Alaska is home to many remote microgrids. For example, Sandia is collaborating with the Cordova Electric Cooperative (CEC) and the Alaska Center for Energy and Power (ACEP) to investigate the feasibility of using energy storage to reduce diesel fuel consumption and make optimal use of existing hydro generation. The basic concept is that the energy storage system will provide contingency reserve capacity, deliver more low-cost hydro energy to the load, and extend the period of time when the system can operate in “diesel-off” mode. This project will result in an energy storage system deployment planned for 2017.
