Photovoltaic supporting energy storage policy documents

How do I prepare for a PPA or self-ownership of solar?

To prepare for a PPA or self-ownership of solar (or solar + battery storage) project, EECBG Program awardees will need to identify government departments that should be consulted about solar installation projects, such as facilities/public works; finance; legal; procurement; sustainability; and economic development.

What are the different types of energy storage policy?

Approximately 16 states have adopted some form of energy storage policy, which broadly fall into the following categories: procurement targets, regulatory adaption, demonstration programs, financial incentives, and consumer protections. Below we give an overview of each of these energy storage policy categories.

What is a storage policy?

All of the states with a storage policy in place have a renewable portfolio standard or a nonbinding renewable energy goal. Regulatory changes can broaden competitive access to storage such as by updating resource planning requirements or permitting storage through rate proceedings.

Can a PPA be used for a solar project?

EECBG Program awardees interested in this option, should review the plans early with their local utility. Whether the government chooses a PPA or to own the solar project itself, the federal renewable electricity incentives in the Inflation Reduction Act (IRA) can still be applied to the project.

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 battery energy storage resources developing?

For the most part, battery energy storage resources have been developing in states that have adopted some form of incentive for development, including through utility procurements, the adoption of favorable regulations, or the engagement of demonstration projects.
