ESS Safety Working Group Website

As a result of the 2017 ESS Safety Forum, the energy storage safety working group has created a website intended to foster the collaboration of stakeholders that can impact ESS safety. It is focused on being a repository for information and resources on best practices to manage risk in energy storage installations. It also serves as a collaboration space for the many ongoing activities aimed at developing and codifying these practices.

EPB Energizes Flow Battery in Support of National Grid Modernization Efforts



EPB has energized a 100kW/400kWh Vanadium Redox Flow Battery as part of a national research effort to explore the best use of cutting edge technologies that could be implemented across the United States to modernize the power grid. EPB’s project constitutes a partnership with the U.S. Department of Energy (DOE), Oak Ridge National Laboratory, Sandia National Laboratories, and Pacific Northwest National Laboratory. The battery system for the project is provided by UniEnergy Technologies (UET), a U.S. manufacturer.

Grid-Scale Vanadium Flow Energy Storage System to be Installed at NELHA

The Natural Energy Laboratory of Hawai‘i Authority (NELHA) in partnership with Hawai‘i Electric Light Company (HELCO), the U.S. Department of Energy Office of Electricity (DOE-OE), the Ulupono Initiative, and UniEnergy Technologies (UET) have announced their intent to install a 100kW/500kWh advanced vanadium energy storage system (ESS) later this year at the Hawai‘i Ocean Science and Technology Park (HOST Park) administered by NELHA.

ESS History

The U.S. DOE Energy Storage Systems Research Program (ESS), at Sandia National Laboratories in Albuquerque NM (Sandia), has evolved over three decades of successful battery and power sources research, engineering, and testing, especially as storage technologies relate to electric utilities, renewables, and grid security. In the early 1950s, the U.S. government charged Sandia with a mission to develop power sources for our nation’s nuclear stockpile. That…

Strategic Plan

The DOE Office of Electricity Delivery and Energy Reliability is addressing the need of the community for energy storage safety through the creation of the DOE OE Strategic Plan for Energy Storage Safety (PDF, 685 kb). This strategic plan addresses the need for incident preparedness, scientifically based and standardized safety validation techniques, and safety documentation. The Strategic Plan identifies gaps within these three areas and presents the desired end…

Energy Storage Database

The DOE Global Energy Storage Database is the go-to source for unbiased, accurate, and up-to-date information on energy-storage projects and policies. The database is publicly accessible and simple to use, providing an open-access resource for detailed energy-storage project and policy information, and allowing users to contribute data through a third-party vetting process.



The ESS Mission

The goal of the ESS program is to develop advanced energy storage technologies and systems, in collaboration with industry, academia, and government institutions that will increase the reliability, performance, and competitiveness of electricity generation and transmission in the electric grid and in standalone systems.
