Unlocking Scalable Business Models for Clean Energy Technologies

Developing Clean Energy for Our Communities

As a leading community-scale, clean energy developer with a growing portfolio of projects across a range of technologies, NineDot Energy is creating innovative energy solutions that support a more resilient electric grid, deliver economic savings, and reduce carbon emissions. 

Founded in 2015, backed by Carlyle, and based at the NYU Urban Future Lab in Brooklyn, we’re committed to providing clean energy solutions to the New York area and beyond. And that’s just the beginning.

400 Megawatts by 2026

We plan to develop, build, and operate more than 400 megawatts (MW) of clean energy systems by 2026 that will strengthen the local power grid infrastructure and provide clean, reliable, and resilient power to tens of thousands of New York households and businesses. This is all in support of New York State’s mission to achieve 100% clean energy by 2040.

NineDot has a pipeline of battery storage systems across Downstate New York including projects in Queens, Staten Island, the Bronx, and Long Island that service Consolidated Edison and PSEG Long Island customers. More

Clean Energy Innovator—Out-of-the-Box Solutions

NineDot's name derives from the classic mathematical puzzle for sparking out-of-the-box solutions. As a clean energy developer, NineDot Energy serves as a laboratory for clean energy business model innovation, which involves:

  • Studying behavioral economics to create better customer value propositions

  • Performing predictive analytics to reduce risks and costs

  • Designing financial instruments to allocate risk and align incentives

  • Observing how regulations champion or hinder clean energy

  • Researching nonobvious technology/market fits

At NineDot, we test our ideas by launching our own clean energy businesses in the marketplace—partnering with leading clean-tech equipment providers and financial investors to design first-of-their-kind projects. Each project measures real-world benefits to the environment, energy infrastructure, and end users. Throughout our development process, we refine our business models to make them scalable, bankable, and faster to implement.



We tune our research and development to increase the accessibility and affordability of clean energy to residents and businesses in dense, urban locations through no-money-down, no-downside-risk subscription contracts.



Community-scale distributed energy projects are our sweet spot. They are small enough to provide hyper-local power grid benefits that maximize reliability and resilience and large enough to gain economies of scale.


Quantifying and parsing financial risks can unlock significant new sources of capital for more clean energy development.


Soft costs are the non-hardware costs to build an energy project. They have an outsized role in project economics. We use science & tech innovation to reduce soft costs.


Retail power prices are set by byzantine regulations layered upon a complex mix regional & global market dynamics. We untangle this mess.


We select the technologies, sites, designs, and operations of all our projects to reduce global greenhouse gas emissions and local air pollution.
