Snohomish County PUD announces new energy storage project

Snohomish County PUD  announced its new energy storage project, the first-ever built using the innovative Modular Energy Storage Architecture (MESA).

The PUDs MESA project, located at a substation in Everett aims to accelerate the growth of the energy storage industry, improve reliability and help utilities better integrate renewable energy sources.
The PUD was joined by Washington State Governor Jay Inslee and energy industry partners at a special dedication event on Jan. 15.

The utilitys project includes two large-scale lithium ion batteries at the Everett site, followed by a second project using multiple advanced vanadium flow battery technology later in 2015. The effort is funded in part by a $7.3 million investment from the Washington State Clean Energy Fund.

The PUD system, the first of several MESA energy storage projects the PUD is pursuing this year, positions the state as a smart grid technology leader and creates cost effective solutions to better utilize renewable energy, according to a PUD statement.

The electrical grid needs to change to take on more renewable power, and standards-based storage and software will play major roles in that change, PUD General Manager Steve Klein said. MESA provides standard interfaces to bring more choices for utilities, reduces projects complexity and promises to lower costs.

1Energy Systems, the principal PUD partner, is the architect of the MESA software controls.

To support the Snohomish PUD project and the other Clean Energy Fund projects, the U.S. Department of Energys Pacific Northwest National Laboratory (PNNL) is working with participants to develop use cases, or detailed descriptions of the many ways energy storage can increase renewable energy use and improve grid efficiency and resiliency.

The PUD and the other utilities will consult these use cases as they implement and evaluate their projects.

MESA Project Goals

~ Developing standard electrical and communication interfaces to connect batteries, power converters and software components into modular energy storage systems

~ Helping to foster a robust industry ecosystem of modular energy storage component suppliers. By sharing their learning with other electric utilities and technology suppliers, MESA Project partners are advancing a new, component-based approach to energy storage that gives electric utilities more choice, and enables battery, power converter and software manufacturers to reach more customers while focusing on their core competencies.
