Gridflex Energy, LLC has historically been a leading originator of large-scale energy storage projects, with a specific focus on pumped storage hydropower.

Founded in 2009, Gridflex has an exceptional ability to identify and define the most promising new projects, and we have a unique understanding of how to optimize the value of these projects in combination with renewable energy resources. The pumped storage plants originated by Gridflex will be flexible and firm generating assets, fueled by renewable energy, with superior long-term value to utilities and their ratepayers.

Many of the projects that Gridflex originated are now being developed by rPlus Energies, which is also a leading developer and operator of utility-scale solar, solar+battery, and wind energy projects.
