The Homer Electric AssociationTesla Battery Energy Storage System is a 46,500kW energy storage project located in Alaska, US. The rated storage capacity of the project is 73,000kWh.

The electro-chemical battery energy storage project uses lithium-ion as its storage technology. The project was announced in 2019 and will be commissioned in 2021.


The Homer Electric Association-Tesla Battery Energy Storage System is owned by Homer Electric Association (100%).

The key applications of the project are reliable power supply, increase grid stability and system efficiency.

Contractors involved

Homer Electric Association is the owner. Tesla is the technology provider for the project.

Additional information

The battery will be located at HEA’s Soldatna Generating Plant, a gas turbine facility with a capacity of 47 MW. The battery will allow Homer Electric Association (HEA) to meet its reliability requirements without having to burn additional fuel, resulting in greater system efficiencies, lower greenhouse gas production, and reduced power outages.
