MESA Specifications

MESA-DER (Becoming IEEE 1815.2) 

The MESA-DER specification (version 1 released December 2018) defines the communication requirements for distributed energy resources (DER), with a special focus on utility-scale energy storage systems (ESS). The MESA-DER specification maps the utility SCADA protocol IEEE 1815 (DNP3) to the IEC 61850-7-420 DER information model, thus creating an interoperable profile of DER functions, monitored information, and control commands. This MESA-DER interoperable profile is defined in the DNP3 Application Note AN2018-001 and supports all the IEEE 1547, California Rule 21 DER functions, and the European ENTSO-E DER interconnection requirements. In addition the MESA-DER Specification includes many of the market-based DER functions to support utility grid safe, reliable, and efficient operations, particularly with energy storage or combined PV plus storage plants. As well as these functions, the MESA-DER specification covers the data exchange requirements for ESS configuration management, including ESS role-based access control (RBAC) for different ESS operational states. The DNP3 Application Note of 2018 is available to MESA members and to DNP3 User Group members.
