What NineDot Energy does
NineDot Energy, headquartered at the NYU Urban Future Lab in Brooklyn, is the leading developer of community-scale battery energy storage systems (BESS) in the New York City metropolitan area. Founded in 2015 (originally as CertainSolar) by David Arfin, Adam Cohen, and Nalin Kulatilaka, the company develops, owns, and operates modular lithium-ion storage sites — typically 5 MW output / 20 MWh capacity each, including the first Tesla Megapack installation in NYC at Northeast Bronx — across all five NYC boroughs plus Westchester County and Long Island. Projects participate in Con Edison's non-wires alternative programs (e.g., Brooklyn-Queens Demand Management) and operate under New York's VDER (Value of Distributed Energy Resources) Value Stack program, dispatching stored energy back to the grid during peak demand to displace fossil-fuel peaker plants and integrate intermittent renewables.
The company's revenue model rests on three pillars. The primary stream is a subscription-based remote crediting product in which commercial and institutional building owners subscribe to NineDot battery projects and receive VDER credits applied to their monthly Con Edison utility bills, with NineDot invoicing subscribers at negotiated rates; this also enables subscribers to offset Local Law 97 carbon fines. Second, the company leases or purchases underused land from property owners and converts it into revenue-generating storage sites without owner investment or maintenance obligations. Third, NineDot provides EV charging infrastructure services — sublease, critical power upgrades, reduced-cost electricity, and optional V2G capabilities — to fleet operators (school buses, last-mile delivery, refuse, rideshare) and public charging stakeholders, with the NYC's first V2G pilot launched in August 2022 with Revel and Fermata Energy. Backed by The Carlyle Group and Manulife Investment Management at the equity level and a deep stack of project-level debt and tax equity from Natixis, Deutsche Bank, First Citizens, NY Green Bank, and others, the company has raised over $1 billion cumulatively and operates with a team of 70+ employees.

Revenue model
- Battery Storage Subscription / Remote Crediting: NineDot's primary revenue model involves developing and operating battery storage sites that generate VDER (Value of Distributed Energy Resources) credits when responding to utility calls to export power during high-stress periods. These credits are allocated to subscribers' monthly utility bills, and NineDot invoices subscribers for these credits, often at a discount. Building owners can also earn credits to offset LL97 fines.
- Landowner Lease/Purchase Arrangements: NineDot develops properties in NYC, Westchester, and Long Island into battery storage sites, typically through lease arrangements, with options to purchase land outright. This enables project deployment without requiring landowner investment or maintenance.
- EV Charging Infrastructure: NineDot provides sublease and critical power upgrades for EV charging stakeholders, along with reduced-cost electricity. Optional V2G solutions provide additional revenue opportunities for fleet operators. Revenue from public charging, school bus electrification, last-mile fleet charging, and rideshare charging.

NineDot Energy competitors and assessment
Company assessmentDirect peers
- Stem Inc: AI-driven energy storage and virtual power plant operator focused on commercial and industrial customers. Overlapping customer base (building owners seeking energy bill savings) and use of storage for grid services.
- Key Capture Energy: Developer and operator of grid-scale battery storage projects in the U.S. Comparable in business model as an independent storage IPP focused on wholesale and ancillary services markets.
- Plus Power: Independent developer of utility-scale and community-scale BESS projects across the U.S. Operates similar IPP/developer model with project finance structures, making it the closest pure-play comparable to NineDot.
- Convergent Energy and Power: Independent BESS developer and operator with a portfolio across North America. Shares the project development, financing, and IPP operating model with NineDot's community-scale approach.
Emerging players
- Powin Energy: BESS system integrator supplying hardware and controls to developers including utility-scale projects in North America. Comparable as a participant in the storage project value chain, though more hardware-focused than NineDot's developer/owner model.
- Form Energy: Developer of long-duration iron-air battery systems with multi-state project pipeline. Comparable as a U.S. battery storage IPP targeting wholesale and grid services, though focused on longer-duration use cases than NineDot's community-scale lithium-ion assets.
- Enchanted Rock Holdings: Developer and operator of on-site and community-scale BESS plus natural gas backup for commercial customers. Comparable model of providing grid services and resilience to building owners in regulated markets.
Regional players
- Sunrun: Largest U.S. residential solar and battery installer with VPP aggregation services. Adjacent to NineDot's community-scale model but focused on behind-the-meter residential storage rather than utility-facing front-of-meter assets.
Broad incumbents
- Fluence Energy: Major global BESS integrator and supplier offering hardware, software, and services. Broader incumbent serving utilities and developers, with overlapping exposure to the same project finance and grid services markets NineDot targets.
- Tesla Energy: Operates Megapack BESS and Solar Roof products globally with broad developer and utility customer base. Incumbent supplier to NineDot's own projects and direct competitor for utility-scale BESS development deals.
