Calibrating Solar Energy Storage System Prices

Can energy storage improve solar and wind power?

With the falling costs of solar PV and wind power technologies, the focus is increasingly moving to the next stage of the energy transition and an energy systems approach, where energy storage can help integrate higher shares of solar and wind power.

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.

Are battery storage costs based on long-term planning models?

Battery storage costs have evolved rapidly over the past several years, necessitating an update to storage cost projections used in long-term planning models and other activities. This work documents the development of these projections, which are based on recent publications of storage costs.

How much does a solar photovoltaic cost?

We find that solar photovoltaics in combination with lithium-ion battery at the residential (0.39 to 0.77 EUR/kWh) and utility scale (0.17 to 0.36 EUR/kWh) as well as with pumped hydro storage at the bulk scale (0.13 to 0.18 EUR/kWh) offer the lowest levelized costs.

How can energy storage technologies help integrate solar and wind?

Energy storage technologies can provide a range of services to help integrate solar and wind, from storing electricity for use in evenings, to providing grid-stability services.

Does energy storage improve wind power capacity credit?

Energy storage substantially improves the capacity credit of wind power from 4% to 26%. Levelized cost of hybrid systems assessed across different supply modes and scales. Optimal choice for a hybrid system depends on the scale rather than supply strategy. Levelized cost of utility PV & Li-ion battery systems could reduce by 30% by 2030.
