Why MESA?

Grid-connected energy storage promises large potential benefits. And yet, before safe, affordable energy storage can deliver on its promise, electric utility customers and their suppliers must solve significant problems. Many of these problems boil down to lack of standardization.

MESA Standards clear barriers to growth in energy storage. By making standard connections between components possible, MESA frees utilities and vendors to focus on delivering more cost-effective electricity to more people.

MESA Standards

MESA is currently developing two specifications: MESA-ESS and MESA-Device/SunSpec Energy Storage Model.

MESA-ESS provides a standard framework for utility-scale energy storage system (ESS) data exchanges. The draft specification addresses ESS configuration management, ESS operational states, and the applicable ESS functions from the IEEE 1815 (DNP3) profile for advanced DER functions.

MESA-Device Specifications/SunSpec Energy Storage Model addresses how energy storage components within an energy storage system communicate with each other and other operational components. MESA-Device Specifications are built on the Modbus protocol.
