Helping Utilities Reap the Rewards of Renewable Energy

At ESS Inc., we’re encouraged by the increased amount of renewable energy penetration across the grid. We know that, with wind and solar energy storage deployments growing up to 46% year-over-year, electric utilities need alternatives to lithium-ion that are clean, resilient and have long operating lifetimes and are not cycle limited. Our iron flow battery solutions, the Energy Warehouse(EW) and Energy Center(EC) offer more than double the operating lifetime and cycle capacity of lithium-ion battery storage systems, with a non-flammable chemistry and minimal maintenance requirements.

The ECis a “battery-in-a-building” platform based on the same second generation power module used in the EW with a design approach that enables systems to be tailored to meet virtually any project size with storage durations ranging up to 16+ hours. Its wide-ranging capabilities can help utilities deal with high penetration of intermittent renewables, resiliency requirements and defer major capital expenditures on distribution equipment by time shifting energy. Utilities can easily communicate with ESS Inc’s storage system solutions installed at end-user sites to dynamically manage customer electricity consumption from the grid in response to real-time electricity supplies. Our innovative energy storage solutions also help with frequency regulation and other ancillary services and, furthermore, can reduce a utility’s dependence on fossil fuel generation plants, shifting to a more sustainable model over time.
