Can energy storage equipment operate in parallel with the grid?

In Section 3.1.1 of the Xcel Energy Guidelines for Interconnection of Electric Energy Storage with the Electric Power Distribution System document (Energy Storage Guidelines document), EConfiguration 1A, the energy storage equipment is not capable of operating in parallel1 with the grid.

Can energy storage be a single high-level resource?

This report summarizes over a decade of experience with energy storage deployment and operation into a single high-level resource to aid project team members, including technical staff, in determining leading practices for procuring and deploying BESSs.

How does energy storage work?

Energy storage operates in parallel8 with the grid. Generation, if present is non-renewable. Metering is standard (non-net-metered). Energy storage and generation, if present, are not allowed to export energy to the grid9. The method of achieving #4 must be fully illustrated in the oneline diagram or described below.

How do distributed energy resources work?

Historically, Distributed Energy Resources (DERs) were assembled from discrete components or functional assemblies where the logic and operational approaches could be seen and analyzed. Today, much of the functionality is handled by an on-board computer following firmware and software instructions in order to achieve the desired results.

What is parallel operation of energy storage?

“Parallel Operation of Energy Storage” – a source operated in parallel with the grid when it is connected to the distribution grid and can supply energy to the Interconnection Customer simultaneously with the Company’s supply of energy3.
