Mesa Standards Alliance

The Mesa Standards Alliance is an industry association based in San Francisco, CA, dedicated to promoting the interoperability of distributed energy resources (DER) and utility-scale energy storage systems (ESS). They have developed open and non-proprietary communication specifications, including the MESA-DER Specification based on DNP3 with IEC 61850 data objects, and the MESA-Device SunSpec Smart Storage Specifications, which are becoming the IEEE 1815.2 standard. Their standardized specifications aim to simplify the integration of renewable energy sources, energy storage, and the bi-directional flow of energy on the electricity grid, ultimately facilitating the deployment of safe, affordable, and scalable energy systems.

MESA members, including utilities and energy storage solution providers, collaborate to build interoperability into their products and ensure they are designed for seamless grid integration. By participating in MESA working groups, members can contribute to the development of MESA specifications, learn how to incorporate them into their products and control systems, and share knowledge with peers. The adoption of MESA specifications offers benefits such as reduced deployment costs, increased supplier flexibility, simplified maintenance and system upgrades, and streamlined deployments that meet customer timelines. MESA aligns with international communication standards, including IEEE 1815 DNP3, IEC 61850, and Modbus, and meets all interoperability requirements for IEEE 1547 DER interconnection standard.
