How does solar-plus-storage affect energy systems?

Solar-plus-storage shifts some of the solar system's output to evening and night hours and provides other grid benefits. NREL employs a variety of analysis approaches to understand the factors that influence solar-plus-storage deployment and how solar-plus-storage will affect energy systems.

Is energy storage a viable option for utility-scale solar energy systems?

Energy storage has become an increasingly common component of utility-scale solar energy systems in the United States. Much of NREL's analysis for this market segment focuses on the grid impacts of solar-plus-storage systems, though costs and benefits are also frequently considered.

What are the benefits of solar-plus-storage?

Among other benefits, it can help maintain the stability of the electric grid, shift energy from times of peak production to peak consumption, and limit spikes in energy demand. Solar-plus-storage shifts some of the solar system's output to evening and night hours and provides other grid benefits.

Can solar-plus-storage meet rising demand without gas?

Energy Innovation analysis shows clean energy can come online fast enough to meet rising demand without needing gas to fill the gap, and solar-plus-storage has stepped up.

How much will solar and battery storage cost in 2035?

But solar and battery storage costs have both fallen around 90% over the last decade. By 2035, solar costs could fall nearly 10% and battery storage costs could fall nearly 50%. “New solar plants, even without subsidies, are within touching distance of new U.S. gas plants,” said BloombergNEF’s Amar Vasdev.

Can US factories supply utilities with solar power?

American factories can supply utilities with this new solar and battery power. Domestic solar manufacturing capacity more than tripled from 14.5 GW in 2023 to 50 GW in early 2025, and existing U.S. factories can now produce enough to meet nearly all domestic demand.
