The Changing Landscape of Battery Storage

Robert Magyar • VARTA Storage GmbH

In the last several years, there has been tremendous media attention surrounding the potential for battery storage to play a significantly larger role within the public electricity grids both at the utility level and within the market-side ownership of Distributed Energy Resources. Much like 10 to 12 years ago, when the photovoltaic (PV) solar market was beginning to mainstream, today’s view of the battery storage market often appears complex and confusing. While some see battery storage as the complete answer to the intermittent power production of PV solar energy, others see the technology as costly and difficult to maintain. As in all technologies, the answer is not within the technology itself, but the business model applications and government regulations which will ultimately determine how far ”the great battery storage revolution” will go.

A Review of America’s First Step Towards the Harmonization of Portable Battery Standards: UL 62133

John C. Copeland, VP/COO • Energy Assurance LLC
