Our Mission

Solving Hard
Grid Problems

Plus Power develops, owns, and operates standalone battery storage projects.

With over 8 years of development history built on in-depth, diversified market expertise, Plus Power has leveraged a first-mover advantage in standalone energy storage to develop a diversified portfolio including 11 gigawatts in development in more than 20 U.S. states.

Our data-driven approach allows us to site projects that relieve grid congestion, increase transmission efficiency, and support the transitioning electric grid. 

Revolutionizing Energy

We have the first grid-forming standalone battery resources at scale in the world that are able to respond in milliseconds to the markets’ needs. Our projects also provide critical grid services and have acted as the assets of last resort in wholesale markets, allowing the grid to continue functioning at times of stress and record peak loads.

Plus Power is operating 9 projects in Arizona, Hawaii, Massachusetts, Maine, and Texas, and has developed 2 projects in Texas that are currently operating and owned by others. We leverage best-in-class capabilities from greenfield development through market and power system analysis, origination, finance, engineering & procurement, construction management, and operational asset management.

Ensuring Power Reliability

The power grid is under stress. Half of Americans now risk blackouts that cost $150 billion per year and damage our job-creating industries. In 2021 and 2023, Texas came within 5 minutes of shutting down its power grid for weeks.

Our power grid, in all regions of the U.S., now needs grid stabilizers which Plus Power is delivering with standalone battery power plants.

Standalone batteries uniquely offer both kinds of grid stabilization: ancillary services provided over seconds to maintain grid performance, and stored energy over hours to delivery during energy scarcity events.
