Tesla To Help Alaska Reduce Reliance on Fossil-Fuel Power Plants

Alaska has a non-binding goal to generate 50% of its electricity from renewable sources by 2025. Hydropower being Alaska’s largest source of electricity generated from renewable resources.

Despite Alaska’s high latitude and long winter nights, solar energy plays a role in off-grid applications, especially in remote locations. Solar thermal technologies, primarily for hot water and building heat, and solar photovoltaic panels are used to tap solar energy when it is available, reducing the need for other fuels. Alaska’s largest solar farm came online in October 2018, a nearly 1,800-solar panel, 563-kilowatt project located south of Fairbanks.

According to Electrek: Homer Electric Association (HEA), a member-owned electric utility cooperative based in Alaska, announced that it’s working with Tesla to deploy a big battery:

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 (Battery Energy Storage System) is going to be installed at the Soldotna Generation Plant.

HEA says that the battery is going to enable them to use more renewable energy and less power from plants burning fossil fuels:

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 new project is expected to be in service in fall 2021.
