6 FAQs about Winning the bid for 1 3 billion energy storage

How many battery energy storage systems were awarded a contract?

25 battery energy storage system (BESS) projects of 'between' 3-hour to 6-hour duration were awarded contracts totalling 1,322,810kW (1.3GW). One BESS project of specified 6-hour duration also won a 47MW contract, as did two PHES projects which each got selected for 180MW contracts.

Is investing in battery storage still profitable?

While the storage portfolio provides significant value, flattening of marginal energy prices signals market saturation and no more need for new entry for energy. The 2021 Preferred System Plan calls for 13.6 GW of battery storage by 2032, at which level estimated marginal energy value drops below $3/kW-month.

How much energy storage will a 2032 system provide?

In a 2032 system, 13.6 GW of energy storage is currently planned to provide $835 million to $1.34 billion of annual net grid benefits depending on storage costs, as estimated in the CPUC Energy Storage Procurement Study: Moving Forward, Chapter 3.

When will the energy storage projects be installed?

The energy storage projects will be installed by the end of 2024. In 2013, the CPUC issued Decision 13-10-040 and directed California's three large investor-owned utilities to procure 1,325 megawatts of energy storage by 2020.

What type of energy storage projects are recent contracts for?

Recent contracts are predominantly for much larger transmission-connected energy storage projects. Earlier energy storage contracts were significantly more expensive across all grid domains, and they generally reflect the cost reductions seen in the global storage industry.

How did the energy storage bill impact the energy industry?

The bill enabled several policy innovations to explore and accelerate the scalability of then-emerging stationary energy storage technologies, thereby impacting the energy industry.
