The MESA Standards Alliance values and encourages collaboration among utilities, developers, and vendors in all of its work.
MESA publishes open, non-proprietary specifications and information models that utilities, software developers, and hardware manufacturers use to achieve interoperability among grid-scale energy storage components, as well as between utility control centers and energy storage systems.
All MESA specifications are free to download and use. Sign up below to access links to the relevant documentation.

MESA-ESS (Updated December 2018)
MESA-ESS provides a standard framework for utility-scale energy storage system (ESS) data exchanges. It addresses ESS configuration management, ESS operational states, and the applicable ESS functions from the IEEE 1815 (DNP3) profile for advanced DER functions. For the detailed DNP3 points list and descriptions, this MESA-ESS Specification references the DNP3 Application Note of 2018, which is available to MESA members and to DNP3 User Group members.
MESA-Device (Updated October 2017)
MESA-Device Specifications/SunSpec Energy Storage Model consists of three separate specifications for inverters, meters, and storage, which address how energy storage components within an energy storage system communicate internally and with other operational components. MESA-Device Specifications are built on the Modbus protocol.
