solar plus storage capital expenditure estimate

Does solar-plus-storage become economical as technology costs decline?

As technology costs decline, solar-plus-storage becomes economical in more cases. In addition to the number of economical cases growing, as technology costs decline, the average expected lifecycle cost savings across all base case scenarios increases from 7% to 11% (see Fig. 6) and solar-plus-storage system sizes increase (see Fig. 7 ).

Will the solar-plus-storage market grow?

At the lowest technology cost point modeled, solar-plus-storage is economical in 10 of the 17 locations and in all of the 16 building types modeled. This suggests that the solar-plus-storage market will grow significantly if solar and storage costs continue to decline as expected in the future.

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 is NREL's solar-plus-storage cost benchmarking work?

This work has grown to include cost models for solar-plus-storage systems. NREL's PV cost benchmarking work uses a bottom-up approach. First, analysts create a set of steps required for system installation.

Does solar-plus-storage save money?

In a national market report, Manghani found that solar-plus-storage could reduce commercial customers’ bills by 18–21 percent in the four utility areas studied (PG&E, Con Ed, SCE, and HECO) ( Manghani, ). His report concluded that large hotels and hospitals had the most favorite economics compared to other building types.

Where are solar-plus-storage systems most cost-effective?

The highest potential for savings was found in California, New York, New Mexico, and Alaska. Across all scenarios modeled, solar-plus-storage systems were most often cost-effective in San Francisco, Anaheim, and Los Angeles. These locations have both good solar resource and relatively high demand rates.

At baseline capital costs, over a quarter of solar-plus-storage cases are economical, and the average savings is 9%. The average storage sizes when coupled with PV are three to five times larger than the average for BESS alone (40 kW/175 kWh versus 12 kW/34 kWh).
