Are battery storage projects eligible for resource adequacy attributes?
In California, utility-scale battery storage projects are eligible for resource adequacy attributes. Battery storage contracts (whether for standalone storage projects or solar or wind projects paired with storage) typically include a fixed-price payment for resource adequacy attributes.
What is a battery storage contract?
Battery storage contracts (whether for standalone storage projects or solar or wind projects paired with storage) typically include a fixed-price payment for resource adequacy attributes. Retains operational control of the battery storage facility and the right to collect and retain revenue from sales of electricity discharged from the battery.
How much energy does a behind the meter PV system generate?
If the behind the meter PV system is expected to meet the local onsite demand (i.e., the energy consumption of the facility where the system is installed), typically the system should generate no more than 1.2x of the host facility's annual energy consumption. The applicant should provide the previous year's (all 12 months) utility bills.
How much power should a battery system use?
Battery system power capacity (aggregated across all inverters) should not exceed peak PV production and/or facility peak demand (i.e., the highest kW usage over a 15-minute interval over the last 12 months). Average consumption during high time of use rates (if energy load shifting is the battery use case).
