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. For questions or to comment on the work, please email

Upcoming Event

MESA Technical Workshop

Understanding and Implementing Open Standards for Energy Storage

Monday, November 13 | Cleveland, OH | 10:00 a.m. – 4:00 p.m. EST

The MESA Standards Alliance will host a technical workshop in conjunction with the Energy Storage Association’s (ESA) Energy Storage STUDIO conference. The workshop will be focused on one of MESA’s specifications under development, MESA-ESS, and will provide an overview of the specifications and strategies for implementing and integrating the MESA-ESS specification.

The workshop is intended for two audiences:

  1. MESA members engineering and implementing the MESA-ESS specification.
  2. MESA members or industry participants who would like to implement the specifications, but need an introduction to available tools and direct technical assistance.

The workshop will be a chance for participants to ask questions, provide feedback on implementation, and learn from colleagues.
