National policy on energy storage scale

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 NREL's capacity expansion model accurately represent diurnal battery energy storage?

For this work, researchers added new capabilities to NREL’s Regional Energy Deployment System (ReEDS) capacity expansion model to accurately represent the value of diurnal battery energy storage when it is allowed to provide grid services—an inherently complex modeling challenge.

What is the future of energy storage?

But measuring the value of energy storage is inherently complex—and future systems will likely include multiple storage technologies, adding new complexity. To answer the big questions around the role of storage in our future grid, the National Renewable Energy Laboratory (NREL) has launched the multiyear Storage Futures Study (SFS).

Is energy storage cost-competitive?

The Storage Futures Study considers when and where a wide range of storage technologies are cost-competitive, depending on how they are operated and what services they provide for the grid. With declining costs, improved technologies, and increasing deployment, energy storage is poised to become a growing part of the evolving U.S. power system.

Do energy storage technologies need integration technologies?

For energy storage technologies to be connected to the electric grid, integration technologies are often required. These integration technologies may include power electronic systems, conversion, electric motors, and protection and isolation systems.
