6 FAQs about [Caiso energy storage cpuc]

How does the CAISO integrate energy storage and distributed energy resources?

Towards wholesale market integration, the CAISO has a broad set of initiatives to better integrate energy storage and distributed energy resources into its marketplace (see Figure 22 for more detail). In 2013 IOUs piloted contracts to bring customer aggregations into energy and RA capacity markets.

Do CAISO aggregations produce negative energy value?

These resources also produce negative energy value on average. The CAISO-participating customer aggregations perform better than non-CAISO resources, but still below their operating potential. These resources produce $1/kW-month of energy value on average. Avoided resource adequacy cost: Results follow patterns of energy value.

Does CAISO operate a resource as a transmission asset?

No resource operated specifically as a transmission asset operated by CAISO. This specific use case is still in a very early pilot and demonstration phase. One resource was procured under the storage as a transmission asset (SATA) use case in 2019 but has yet to be developed.

What will the CPUC's next energy storage procurement study look like?

In its next energy storage procurement study the CPUC will have even more historical data to work with—likely with more complex market interactions as storage penetration increases.

Are CAISO batteries fully charged during a heat wave?

However, aggregate state-of-charge for the CAISO battery fleet tended to stay below 90 percent of total charge capacity (around 13,600 MWh) throughout the heat wave. Batteries would not be fully charged—even in the hours preceding peak load—as a result of any of the constraints listed in Section 3.1.

Is CPUC energy storage scalable?

• It is scalable down to 8 kWh for residential installations so presents a sheer data volume issue. CPUC Energy Storage Procurement Study: Realized Benefits and Challenges Chapter 2
