The Anchorage Area Battery Energy Storage System-BESS is a 25,000kW energy storage project located in Alaska, US.

The electro-chemical battery energy storage project uses lithium-ion as its storage technology. The project was commissioned in 2016.


The key applications of the project are electric energy time shift, electric supply reserve capacity – spinning, load following (tertiary balancing), transportable transmission/distribution upgrade and deferral.

Additional information

This project includes the installation of a 25 MW / 14 mWh Battery Energy Storage System (BESS) in the Anchorage area. This device will add stability to the system and provide a measure of “spin” to facilitate spooling-up alternative generation in the event of an outage.


All publicly-announced energy storage projects included in this analysis are drawn from GlobalData ’s Power IC. The information regarding the projects are sourced through secondary information sources such as country specific power players, company news and reports, statistical organisations, regulatory body, government planning reports and their publications and is further validated through primary from various stakeholders such as power utility companies, consultants, energy associations of respective countries, government bodies and professionals from leading players in the power sector.
