December 3, 2019 – Homer Electric Association, Inc. announces a strategic move to increase grid stability, electric power reliability and system efficiency for its members by the addition of a BESS (Battery Energy Storage System).
The BESS will be capable of storing 93 MWh (Megawatt hours) of electrical power that can be delivered to the grid at a rate of 46.5 MWs per hour. The BESS will allow HEA to meet its reliability requirements without having to burn additional fuel. This will result in greater system efficiencies, lower greenhouse gas production, and reduced power outages.
The BESS also provides a great side benefit of opening the door to renewable intermittent energy projects that would have otherwise stretched current thermal generation assets. The BESS project is expected to be in service in the Fall of 2021.
The proposed site for the installation of the BESS is at the Soldotna Generation Plant located at the corner of the Sterling Highway and Boundary Road. HEA signed an agreement with Tesla for the purchase of the batteries and currently cost information is not available for public release. POWER Engineers, Inc. was awarded the site engineering contract. More details to evolve as we move forward to making this a reality on the Kenai peninsula.
