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.

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.
