ESS Iron Flow Technology and Florida Sunshine Deliver Clean Energy and Reduce Dependence on Fossil Fuels

October 17, 2022

By Hugh McDermott, SVP Sales & Business Development

In Florida, abundant sunshine means that solar generation can deliver plentiful, low-cost clean energy when the sun is shining. Now, new long-duration energy storage (LDES) technologies make it possible to store excess solar energy generated during the day to use whenever it is needed, not only when the sun shines. The ESS Energy Center™ is a scalable iron flow battery platform that can provide megawatts, or even gigawatts, of energy storage capacity and is an ideal complement to utility-scale solar generation projects.

In July, ESS reached an agreement for delivery of an Energy Center to Tampa Electric Co. (TECO), which will complement TECO’s renewable assets and both reduce dependence on fossil fuels and allow for solar peak shifting. TECO is Florida’s top producer of solar energy per customer, with a portfolio of projects generating enough power to supply the equivalent of 160,000 homes per year.

Like other utilities, TECO is taking steps to reduce reliance on fossil fuels in order to cut CO₂ emissions and reduce environmental impacts. To provide clean energy even when the sun is not shining, TECO turned to ESS to deliver an eight hour long-duration iron flow battery system, scheduled to come online in 2023.

ESS’s LDES platform is based on a safe and non-toxic iron-based electrolyte and the system is designed for a 20+ year life and unlimited charge cycles with minimal maintenance.

The clean energy transition will be led by forward-thinking utilities like TECO, deploying significant renewable resources paired with sustainable LDES to support the grid and provide power when needed. Reliable and sustainable long-duration energy storage is the ideal complement to solar generation.

This project is further evidence that utilities can realize multiple benefits when combining ESS long-duration storage with renewables. We’re honored to be selected by TECO as a storage solution provider for Big Bend, and we’re excited for the opportunity to demonstrate the value of ESS’s iron flow battery solution as a key component of TECO’s sustainability efforts.
