What we do

Flatiron develops utility-scale battery energy storage systems, overseeing the process from property acquisition, to design and construction,
and to long-term operations.

Transforming surplus power into reliable energy with storage

The clean energy transition requires energy storage systems to provide reliable and consistent power. Renewable energy sources like solar and wind produce power intermittently, and electricity demand doesn’t always match supply. When demand exceeds renewable supply, grid operators must tap into fossil fuel sources like oil and natural gas.

Energy storage provides a way to capture surplus clean energy—which would otherwise be lost—so it can be used later. Common examples include storing solar energy produced during the day to use at night or storing wind energy produced on windy days to use on calm ones.

Our process
Project development

We identify strategic locations for battery storage that maximize impact to reduce carbon emissions in urban, suburban, and rural environments of the Northeast and Mid-Atlantic U.S.

Community engagement

We collaborate with community members to ensure they have
a voice in their neighborhood and that nearby storage projects have a positive impact.

Permitting and safety

We partner with state and local officials to ensure that our projects comply with the highest safety regulations and environmental standards, prioritizing both safety and sustainability.

Commercial structuring

We create project offtake agreements through innovative power marketing strategies, robust policy engagement, and by building and nurturing strong partnerships to drive success.

Storage operations

We bring more than 29 years of in-house energy storage management experience, and we partner with market leaders to deliver profitable projects enabling the clean energy transition.

Our difference
Scale

Energy can be stored to serve the needs of individuals and businesses. Flatiron develops utility-scale storage systems that are large enough to meet the needs of the electricity grid and serve entire communities.

Location

Flatiron identifies areas with the most critical reliability needs and develops advanced industrial spaces to store energy, focusing primarily on urban markets in the Northeast and Mid-Atlantic U.S. Flatiron helps ensure efficient energy management to support the region's growing energy demands.

Reliability

Flatiron sources equipment and materials that have minimal environmental impact. All batteries in Flatiron projects come from top-tier vendors and are stored in specially designed, climate-controlled environments that maximize safety and efficiency.

Experience

With nearly 30 years of collective experience in standalone energy storage
and 70 years of experience in the energy industry, Flatiron’s managing partners have the expertise to rise to any occasion and deliver on new projects.
