4 FAQs about Preferential policies for grid-connected power storage cabinets for bridge applications
Why is grid-connected energy storage important?
As the electricity sector relies more on variable energy sources like wind and solar, grid-connected energy storage will become increasingly important to support reliable electricity supply. Storage can transfer electricity generated during hours when renewable energy is plentiful to meet demand at other times of the day.
What did the energy storage rulemaking entail?
This rulemaking identified energy storage end uses and barriers to deployment, considered a variety of possible policies to encourage the cost-effective deployment of energy storage systems, including refinement of existing procurement methods to properly value energy storage systems. This rulemaking resulted in two CPUC Decisions, which are:
What are the different storage requirements for grid services?
Examples of the different storage requirements for grid services include: Ancillary Services – including load following, operational reserve, frequency regulation, and 15 minutes fast response. Relieving congestion and constraints: short-duration (power application, stability) and long-duration (energy application, relieve thermal loading).
What standards are required for energy storage devices?
Coordinated, consistent, interconnection standards, communication standards, and implementation guidelines are required for energy storage devices (ES), power electronics connected distributed energy resources (DER), hybrid generation-storage systems (ES-DER), and plug-in electric vehicles (PEV).
