The Graham Energy Center project supports America’s economic growth, strengthens communities and contributes to our nation’s energy independence.

Discover how Graham Energy Center is creating local opportunities, delivering energy and shaping a brighter future. Explore the project’s benefits for you and your community—and get answers to your battery energy storage questions.

A storage system consists of:

  • Individual battery cells.
  • These cells are collected into modules and housed in a specially designed, climate-controlled storage container.
  • The racks fill containers, not unlike a storage container you’d see on a ship or truck.
  • The containers are paired with inverters to convert DC to AC electricity.
  • Can be paired with a renewable energy asset (solar, wind) or stand alone.

Battery energy storage helps optimize the way the power grid delivers electricity to customers including:           

  • Reduces fluctuations in voltage
  • Reduces energy losses and waste
  • Avoids the need for some system upgrades, including big transmission projects
  • Extends the hours a renewable energy project can operate, i.e., even after the sun goes down or the wind stops blowing
  • Allows customers to enjoy more renewable energy, more hours of the day

Energy storage delivers several advantages to the power grid and our customers. What makes energy storage attractive is that it can store electricity and deliver it later at a more appropriate time, in the required amount, to either grid operators or direct consumers.

We primarily use lithium-ion battery technology, which has benefited from years of research and development and has been proven to be safe, efficient and cost-effective for utility scale battery energy storage. We are always evaluating other battery chemistries and technologies to continue to advance this growing industry.

Fires involving battery energy storage systems are rare. At NextEra Energy Resources, the safety of our employees, neighbors and the public are always our highest priority. Responsible energy production begins with preparation from day one.

  • Batteries used in our facilities undergo rigorous industry testing and certification by Underwriters Laboratories (UL). This ensures that the cell and module designs are robust.
  • Battery modules are housed in fully enclosed containers, like shipping containers.
  • Each container is equipped with fire protection and explosion control systems to comply with the National Fire Protection Association.
  • We have sensors that alarm when an abnormal condition arises. Additionally, our facilities are monitored 24/7 by our Renewable Operations Control Center, which can remotely shut down any affected site.
  • We work and train with local first responders and fire officials to coordinate any response, in the unlikely event of a fire.
