Overview

Mission

Promote energy storage industry through open standards

What it reported doing in 2025

Mesa has developed two specifications: mesa-der and mesa-device/sun spec energy storage model.der specifications address how energy storage systems, microgrids, aggregators and facility energy management systems (fdems) communicate with the utility's grid control (scada/dms) that monitor and control grid assets. Mesa released the first draft of the mesa-der specification (formerluy mesa ess) at the end of 2018. Mesa updates this specification periodically and this work is now being incorporated into the ieee 1815.2 standard. Mesa has also developed a program for mesa-der/ieee 1815.2 testing and certification.mesa-device specifications/sun spec energy storage model addresses how energy storage components of an energy storage system are packaged and arranged, electrically connected and able to communicate with each other and other operational components. Mesa-device specifications are built on the modbus protocol. Mesa and sun spec alliance released the first draft energy storage system specification, mesa-device (referred to as the energy storage model specification by sun spec), for public review and adoption in october 2014 and updates this specification periodically. Mesa created the testing and certification program with sun spec in 2024.

Operating model

Revenue model
Cannot be determined from the filing. The filing does not provide enough consistent revenue detail to tell how this nonprofit funds its work.
Distribution model
Direct operator. The filing allocates 100% of reported program-service expenses outside its grant, affiliate-payment, and member-benefit lines. This expense classification does not rule out separately announced grant awards.
