Solar projects with energy storage

Should battery energy storage systems be integrated with solar projects?

Integrating battery energy storage systems (BESS) with solar projects is continuing to be a key strategy for strengthening grid resilience and optimising power dispatch. With proper planning, power producers can facilitate seamless storage integration to enhance efficiency.

Why do solar projects need battery storage?

Considering space, electrical infrastructure and control systems early in a solar project’s design phase allows sites to remain adaptable as the grid landscape evolves. The growing adoption of battery storage alongside solar is driven by the ability to use the same interconnect and substation, making permitting and interconnection more efficient.

How do I add storage to a solar project?

Generally, the quickest path to add storage to a solar project is under the same interconnection. A well-planned project allows storage to be incorporated within the existing PV interconnection, streamlining the regulatory approval process and saving time. However, projects must account for strategic considerations.

Where is the US' largest solar & battery storage project now?

One of the US’s largest solar + battery storage projects is now fully online in Mojave, California. Arevon Energy ’s Eland Solar-plus-Storage Project combines 758 megawatts (MWdc) of solar with 300 MW/1,200 megawatt hours of battery storage. Eland 1 reached commercial operation in December 2024, and Eland 2 recently commenced full operation.
