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 Xcel Energy interconnect a non-paralleling energy storage system?
If the energy storage system is operated ONLY in a non-paralleling mode, and such operating mode is secured from changes by unqualified personnel and end users2, submittal of this signed declaration allows interconnection of the energy storage portion without an interconnection review by Xcel Energy.
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.
Can an energy storage device be interconnected without an interconnection review?
The declaration allows interconnection of the energy storage device without an interconnection review if this mode is secure from change. In Energy Storage Guidelines document Section 3.2.1, Configuration 2A, the energy storage equipment is not capable of operating in parallel with the grid.
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.
What is an end-user facility interconnection?
End-user facility interconnections. In summary, although an AS-PSH facility is a modern power plant with a combination of AC generator and power converter, the electrical systems of pumped storage hydropower (PSH) plants are similar to any other power plant.
