Nine dots on a page. Most people stay inside the box. NineDot Energy was built by people who never saw the box as mandatory, or even interesting. Founded in 2015 and forged in New York City’s hardest constraints, this company has been quietly training for moments like this while everyone else argued about hypotheticals and timelines.
This week, NineDot Energy closed $431M in debt financing led by Natixis Corporate and Investment Banking as sole lead arranger and bookrunner. 28 battery energy storage projects. 124 MW. 494 MWh. All planted inside the tight, unforgiving geometry of New York City, where nothing scales unless it earns its right to exist.
David Arfin (CEO), Adam Cohen (CTO), and Nalin Kulatilaka (Co-Founder) did not arrive here by accident. One brought the commercial instincts that helped birth SolarCity’s SolarLease. One brought the physics, forged at the Department of Energy. One brought the academic rigor that changed how solar risk gets priced. Different lanes, same destination. Build energy infrastructure that actually works when the heat hits and the grid starts sweating.
Natixis did not write this check for a pitch deck. Jim Kaiser, Head of Infrastructure and Energy, North America at Natixis Corporate and Investment Banking, backed execution. This financing accelerates construction of 28 community-scale battery systems across the Bronx, Brooklyn, Queens, Staten Island, Westchester, and Long Island. Systems that charge while the city sleeps and discharge when demand spikes, replacing peaker plants with silence and electrons that show up on time.
7 projects are already operating. 60+ are in the pipeline. By the end of 2026, NineDot Energy expects to have roughly 400 MW in operation, construction, or development. These batteries can power 100,000+ New York City households during peak hours on the hottest summer days, the moments when reliability stops being theoretical and starts being personal.
This capital stack is a case study. Equity support from The Carlyle Group and Manulife Investment Management. Prior debt from CIT, SMBC, NY Green Bank, and NYSERDA. Real estate financing from SolaREIT. Tesla Megapacks approved under the strictest safety standards in the country. Starbucks anchoring subscriptions. Every piece intentional. Nothing decorative.
The real flex is not the dollar figure. It is precision. Transforming contaminated sites. Enrolling every new project in New York’s Solar for All program. Designing infrastructure that lives inside neighborhoods instead of looming over them. Zero storage fires. Zero shortcuts. In a city built on pressure, NineDot Energy keeps finding space, connecting dots most people never notice, and turning constraint into current.
