MESA Standard Specifications

The Modular Energy System Architecture (MESA) Standards Alliance is an industry association of electric utilities and technology suppliers. MESA’s mission is to accelerate the interoperability of distributed energy resources, in particular utility-scale energy storage systems, through the development of open and non-proprietary communication specifications.

Join us in transforming the energy system market.

MESA has developed two specifications

MESA-DER

Provides an interoperable communications specification of data exchanges for Distributed Energy Resources (DER) with a special focus on utility-scale energy storage system (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 and California Rule 21 DER functions as well as additional market-based DER functions to support utility grid safe, reliable, and efficient operations. In addition, 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.

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.

About MESA Standardized Specifications

Utility grid technologies are undergoing a rapid evolution in response to changes in how power is being deployed on the electricity grid today.

Changes from the last decade include the integration of renewable energy sources, the addition of energy storage, and the bi-directional flow of energy between the grid and distributed energy resources (DER).

The adoption of open and standardized specifications simplifies the integration of these technologies and increases the pace of their deployment in grid applications.

MESA members include utilities and energy storage solution providers who work together to build interoperability into their products and ensure they are architected for grid integration.

As a MESA member, you can participate in MESA working groups to guide the development of MESA specifications, learn how to incorporate MESA specifications into your products and/or control systems, and share knowledge with your peers.
