Power management: LG Chem, 1Energy Systems and Snohomish Public Utility District Successfully Commission Energy Storage System in the Pacific Northwest
Energy management:Snohomish County Public Utility District (PUD), 1Energy Systems and LG Chem have successfully commissioned a 1MW, 500kWh advanced Battery Energy Storage System (BESS) as a core component of the MESA-1 energy storage system.
The MESA-1B system is installed at the PUD’s Hardeson Substation and is built on the innovative MESA (Modular Energy Storage Architecture) Standards Alliance communication standards.
“The successful system commissioning with the Snohomish PUD and 1Energy Systems is an example of how the MESA standards facilitate system deployment,” said Sunghoon Jang, Senior Vice President of the Energy Solution Company at LG Chem. “The MESA-compliant system enabled the PUD, 1Energy, and LG Chem to rapidly commission the system for swift deployment by the PUD.”
The MESA Standards Alliance is developing non-proprietary communication standards that allow utilities or grid operators to choose interoperable components – batteries, power converters and software – to meet specific needs and use cases and implement a scalable approach to energy storage. The ability to exchange components also makes it easier and more cost effective for utilities or other customers to upgrade or replace components as new technologies emerge.
LG Chem’s energy storage solutions have been successfully deployed worldwide for grid-scale, commercial & industrial, and residential applications and are built on the technology, constant innovation, and extensive field validation of the company’s overall energy solution business, which also includes battery products for consumer electronics and vehicle applications.
“Our work with LG Chem is another example of how MESA’s component-based approach provides utilities with greater choice and reduces project-specific engineering costs,” said Snohomish PUD CEO/General Manager Craig Collar. “MESA’s standardization frees utilities and vendors to focus on delivering cost-effective electricity to more people.”
“With MESA 1B’s commissioning, we’re seeing the benefits of open standards,” said David Kaplan, CEO of 1Energy Systems. “Even though this system features different components than other Snohomish systems, the integration and commissioning of the system has gone very smoothly. We are pleased to see that open standards are helping to provide the foundation for Snohomish PUD’s scalable energy storage fleet.”
The MESA-1B Project, announced in 2014, also includes partners: Parker Hannifin, provider of the MESA-compliant 890GTB power conversion system (PCS); Alstom Grid, making its e-Terra control center software platforms MESA-compatible; and University of Washington faculty, providing research expertise in electric power systems and computer science.
MESA Standards Alliance Goals
The goals of the MESA Standards Alliance are to:
• Standardize communications and connections, which will accelerate interoperability and scalability of energy storage systems;
• Give electric utilities more choice 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; and
• Reduce training costs and improve safety for field staff through standardized procedures for safety and efficiency.
Key MESA goals that were advanced through the MESA-1 project include:
• Developed standard electrical and communication interfaces to connect batteries, power converters and software components into modular energy storage systems.
• Fostered a robust industry ecosystem of modular energy storage component suppliers.
• Shared MESA-1 learning with other electric utilities and technology suppliers.
In support of these goals, MESA Standards Alliance members will work with industry standards organizations to publish MESA specifications, and make key MESA technologies available in the public domain.
The PUD project was made possible in part by a $7.3 million investment from the Washington State Clean Energy Fund. The Washington State Department of Commerce awarded more than $14 million in grants for demonstration projects that will help utilities better integrate intermittent renewable electricity, increase the efficiency of their systems and improve grid reliability.
