The SunSpec Alliance (SunSpec) and the MESA Standards Alliance (MESA) have jointly released the first open, non-proprietary energy storage system specification for public review.
The specification referred to as SunSpec Energy Storage Models Specification and incorporated in MESA specifications as a “MESA-Device,” was developed through a joint effort and proposes standards for how the different components of an energy storage system (power meters, power conversion systems and batteries) communicate with one another.
“As utilities upgrade their operations to effectively manage and integrate the next generation of distributed assets, standards like SunSpec and MESA, will be essential to successfully achieving the smart-grid vision,” says Craig Collar, assistant general manager of the Snohomish County Public Utility District and MESA Board Member.
A Technical Storage Working Group met weekly over the past nine months to draft the specification. The Working Group included input from a variety of industry participants and built upon SunSpec’s prior work on power meters and power conversion systems and then added battery models to that base.
“By using SunSpec’s protocols as the foundation, the group’s efforts were greatly accelerated,” says Tom Tansy, Chairman of the SunSpec Alliance. “SunSpec is proud to release the SunSpec Energy Storage Model adopted by MESA — it is a major energy storage industry innovation.”
The draft specification can be found on the SunSpec and MESA websites. The Technical Work Group will be accepting public input through the end of 2015.
