Is the US a promising market for commercial solar-plus-storage?

Tokash at al. reported that the United States is a promising early market for commercial solar-plus-storage, highlighting Hawaii, California, and states that have implemented Small Generation Incentive Programs (SGIP)s ( Tokash and Dehamna, 2017 ).

Are solar-plus-storage projects economically viable?

Technology cost and utility rate structure are key drivers of economic viability of solar and storage systems. This paper explores the economics of solar-plus-storage projects for commercial-scale, behind-the-meter applications. It provides insight into the near-term and future solar-plus-storage market opportunities across the U.S.

Where is solar-plus-storage available?

Near term markets exist for solar-plus-storage in locations such as California and New York. As technology prices drop, the number of building types that can benefit increase, and additional markets appear in Colorado, New Mexico, and Alaska.

How many solar panels are there in the United States?

According to NREL, there’s only one utility-scale PV system in the United States connected to storage, and it’s a 13 MW PV plant with 52 MWh of storage in Kauai, Hawaii. There are more systems that have storage co-located with a solar array, but those batteries can be charged by other sources of power on the grid.

Will increasing utility rates increase solar-plus-storage savings?

This suggests that, similar to falling technology costs, increasing utility rates will result in a larger number of solar-plus-storage systems, larger system sizes, and increased savings from each system. On average, savings were highest for projects that combined both solar and storage (see Fig. 13 ).

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.
