Sunnyvale, California. June 6, 2016. Nuvation Engineering has announced that their battery management system for large-scale energy storage systems (ESS) is now conformant with Draft 3 of the MESA-Device/SunSpec Energy Storage Model. “MESA Draft 3 conformant products share a common communications interface that exposes all the data and control points required for operating the energy storage system,” said John Corman, Vice-President, Engineering and Product Management at Nuvation. “Nuvation BMS can now be integrated with any other MESA-conformant energy storage hardware or software without the custom middleware often required to enable different companies’ products to work together.”

“Nuvation’s attainment of Draft 3 conformance streamlines the integration of their battery management system with Parker’s MESA-conformant inverters and 3rd-party site controllers on the Alevo GridBank project,” said Daniel Friberg, Division Engineering Manager, Parker Hannifin. “As a founding member of MESA, Parker views Nuvation’s adoption of MESA standards and their ongoing involvement as an important step in simplifying the integration of Nuvation BMS into energy storage systems.”

The MESA (Modular Energy Storage Architecture) Alliance is a California-based non-profit organization that was created to develop shared open standards and communication protocols for energy storage systems. Its work includes close collaboration with related groups including the SunSpec Alliance and the Electric Power Research Institute. MESA members include many of the energy storage industry’s leading utilities, ESS developers, battery manufacturers, energy management companies, and power conversion system (PCS) manufacturers. The goals of this industry-driven effort towards standardization include giving electrical utilities more choice by enabling multi-vendor, component-based energy storage systems.

“Nuvation’s MESA-conformant BMS can be integrated with 1Energy’s Intelligent Controller product with minimal effort and expense, which makes it an excellent battery management solution for energy storage systems that are being managed by our software,” said Andrew Miller, VP of Engineering, 1Energy Systems. “Nuvation’s contributions to MESA over the past year have accelerated the energy storage industry’s progress towards open standards for ESS design and ensured that battery management systems are well covered by the standard.”

Nuvation Engineering joined MESA in February, 2015 and is currently collaborating with other MESA members to develop the Draft 4 specification. Draft 4 will include new battery models that expose significant additional measurement and performance data for lithium-ion batteries. In addition, it will include definitions for commonly used terms such as “State of Health” and “State of Charge,” which can often be a source of confusion within the energy storage industry.

MESA, vanadium batteries put to the test in Pacific Northwest

Peter Key, Energy Biz December 1 2015

Key excerpts from the article:

“Three Washington state utilities are deploying a total of five cutting-edge systems that will be evaluated by the Pacific Northwest National Laboratory in Richland, Wash. Three of the systems were constructed according to a set of standards designed to make utility-scale storage systems easier and cheaper to build, and two use a new type of battery system based on technology developed at the lab.

The utilities received a total of $14.3 million from the state’s Clean Energy Fund for the energy-storage projects and had to put up an equal amount themselves…The utilities that received the funds are Bellevue-based Puget Sound Energy, Spokane-based Avista Corp. and the Snohomish County Public Utility District, which is headquartered in Everett.

The Puget Sound Energy and Snohomish PUD projects use the Modular Energy Storage Architecture – or MESA – set of specifications and standards, which were developed by a group of utilities and their suppliers.

MESA is meant to solve a problem that often plagues early deployments of a technology, which is that each is treated uniquely, increasing the time and effort of doing it.

Utility-scale storage is expected to be big business in the coming decade. According to a forecast from Navigant Research, the market will exceed $2.5 billion in revenue by 2023.”

Contact: Ben Ealey ( or Darcy Wheeles (
Meetings: Bi-Weekly
Registration: Use this link to register for the webinar.

EPRI and MESA are collaborating on an effort to support capability and interoperability of energy storage communications and controls. EPRI’s Energy Storage Integration Council (ESIC) is launching an open forum that will leverage and review MESA’s existing and ongoing work in this space. The group will take a phased approach to ensure architectures and functionality exist for energy storage to provide high value benefits to the grid and customers. Success in this effort will include 1) identification and definition of all required functions of energy storage to provide desired services and 2) maximum leverage of existing standards and collaborative efforts supporting convergence toward interoperability. The group will leverage and review MESA’s existing and ongoing work in this space.

We need your help to make this happen. EPRI and MESA are looking for stakeholders to join the conversation including vendors, utilities, and other industry experts in both communications and energy storage. Ideal candidates for this task include application and software engineers involved in communications to distributed energy resources from both the utility and manufacturer side of energy storage.

This activity is expected to have four phases, which will be further socialized at this kick-off meeting.  1) Identify grid services that are relevant to energy storage. Grid services will serve as the objective for identifying gaps common smart inverter functions in this effort, 2) Map functions from EPRI’s Common Functions for Smart Inverters, Version 3 ( – 3002002233) to the grid services and identify gaps, 3) Update and add new functions as needed to fill gaps, 4) Map protocols to updated functions.

Epri Workgroup
The primary output of this activity is envisioned to be a publicly available white paper that will outline the changes to the common functions as well as other considerations for communications in this space. The updated functions will also be preserved within an update to the publically available Common Smart Inverter Functions following the white paper’s release.

We hope you’ll participate in the kick-off on November 13th at 10:30am Pacific / 1:30pm Eastern to weigh in on your challenges and make suggestions to refine the scope of this activity for maximum impact.
