Which energy storage technologies are included in the 2020 cost and performance assessment?

The 2020 Cost and Performance Assessment provided installed costs for six energy storage technologies: lithium-ion (Li-ion) batteries, lead-acid batteries, vanadium redox flow batteries, pumped storage hydro, compressed-air energy storage, and hydrogen energy storage.

Will California's New PV rules affect PV-plus-storage systems?

In the longer term, analysts expect the new rules to constrain PV-only deployment in California and ultimately spur the deployment of PV-plus-storage systems, which have higher upfront costs (Wood Mackenzie and SEIA 2022b). Our interviews also indicated market and policy trends affecting system costs between Q1 2022 and Q1 2023.

What are the cost parameters for a commercial Li-ion energy storage system?

Commercial Li-ion Energy Storage System: Modeled Cost Parameters in Intrinsic Units Min. state of charge (SOC) and max. SOC a Note that, for all values given in per square meter (m2) terms, the denominator refers to square meters of battery pack footprint. The representative system has 80 kWh/m2.

How are PV and storage market prices influenced?

On the other hand, PV and storage market prices are influenced by short-term policy and market drivers that can obscure the underlying technological development that shapes prices over the longer term.

Do small-scale installers in the residential sector have a larger PV system?

We infer the predominance of small-scale installers in the residential sector using data on residential system financing (Wood Mackenzie 2022b). The higher efficiency of modules assumed for Q1 2022 (CA NEM 2022) results in larger residential PV system sizes compared with systems in Q1 2021.

What solar policies did the US Institute between Q1 2022 & 2023?

Additional solar-relevant U.S. policies instituted between Q1 2022 and Q1 2023 included the Inflation Reduction Act (IRA) and California’s revised net metering rules.
