MESA-ESS Draft Specification defines communication requirements between utility control centers and utility-scale energy storage systems (ESS). The draft addresses ESS configuration management, ESS operational states, and the applicable ESS functions from the IEEE 1815 (DNP3) profile for advanced distributed energy resources (DER).

The specification outlines the approach and initial models and the DNP3 Point Spreadsheet provides a DNP3 Profile for implementing the specification.

The MESA-ESS Workgroup worked through 2015 and 2016 to develop the specification. The specification was released in DRAFT status for feedback and testing in November 2016.

UPDATE: As of June 2018, the MESA-ESS Workgroup has reconvened to update the specification. The MESA-ESS technical workgroup kickoff webinar was held on Wednesday, June 20. Link to webinar recording.
