We are a Founding Member of the MESA Standards Alliance

The Modular Energy Storage Architecture (MESA) Standards Alliance is an industry trade association of utilities and vendors whose mission is to accelerate the growth of the energy storage industry through the development of open, non-proprietary communication specifications for energy storage systems. Through standardization, MESA accelerates interoperability, scalability, safety, quality, and affordability in energy storage components and systems. Doosan GridTech is a founding member of the MESA Standards Alliance.

Why MESA?

 
  • Grid-connected DER and energy storage systems benefit the electric power industry and all electric users, from the smallest residential cu stomers to the largest industrial plants.
  • Communications are critical for managing grid-connected DER, and standardized communication specifications are therefore key to the deployment of large numbers of DER and ESS across all grids worldwide.
  • MESA standardized communication specifications clear barriers to this critical need for interoperability.
  • Through standardization of communication specifications, MESA accelerates interoperability, scalability, safety, quality, availability, and affordability in distributed energy resources (DER), in particular energy storage systems (ESS) and their components.
 

MESA Objectives

 
  • Standardize communication and connections, which will accelerate interoperability and scalability of energy storage systems.
  • Give electric utilities more choices by enabling multi-vendor, component-based energy storage systems.
  • Reduce project-specific engineering costs, enabling a more robust energy storage market.
  • Enable technology suppliers (from software developers to battery suppliers) to focus on their core competencies in producing quality, safe, and cost-effective components.
  • Reduce training costs and improve safety for field staff through standardization procedures for safety and efficiency.
  • Expedite the development and industry deployment of storage-specific communication specifications before submitting them to appropriate Standards Development Organizations (SDO).
   

MESA-DER

The MESA-DER specification (version 1 released December 2018) defines the communication requirements for distributed energy resources (DER), with a special focus on utility-scale energy storage systems (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, California Rule 21 DER functions, and the European ENTSO-E DER interconnection requirements.   In addition, the MESA-DER Specification includes many of the market-based DER functions to support utility grid safe, reliable, and efficient operations, particularly with energy storage or combined PV plus storage plants. As well as these functions, 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. The DNP3 Application Note of 2018 is available to MESA members and to DNP3 User Group members.

MESA-DEVICE

MESA-Device Specifications/SunSpec Energy Storage Model consists of three separate specifications for inverters, meters, and storage which address how energy storage components within an energy storage system communicate internally and with other operational components. MESA-Device Specifications are built on the Modbus protocol.   The Energy Storage Workgroup, run by SunSpec Alliance with contributions from MESA members, worked through 2015 and 2016 to produce an updated draft specification for MESA-Device/SunSpec Energy Storage Specification (Draft 4). The specification was released in DRAFT status for feedback and testing in July 2016 and updated October 2017.
