What Nautilus Solar Energy does
Nautilus Solar Energy is a private U.S. community solar developer and long-term owner-operator, founded in 2006 and headquartered in Chicago (relocated from Summit, NJ in June 2025). It is a wholly-owned subsidiary of Power Sustainable, the sustainable-investing arm of Power Corporation of Canada. The company builds, owns, and operates shared "community solar" farms — utility-scale photovoltaic installations whose generated electricity is allocated via subscriptions to residential, commercial, and low-to-moderate-income (LMI) customers within the host utility's territory. Subscribers receive credits on their utility bills — typically a guaranteed 10%+ discount, with 25% discounts available to qualifying LMI households — without installing rooftop panels or paying upfront costs.
The platform consists of a customer-facing enrollment portal (enrollment.nautilussolar.com), a savings calculator, and a subscriber account portal layered over a 167+-site, ~600 MW operating fleet across 12 U.S. states (primarily in the Northeast and Midwest, including CO, DE, IL, MD, ME, MN, NY, and RI). Nautilus runs a full-service operating model, handling financing, development, construction, asset management, and subscriber lifecycle in-house, with supplementary project origination through developer partners such as TurningPoint Energy, Endurance Clean Energy, ESA, and Cipriani.
Nautilus monetizes the spread between the cost of producing solar electricity and the value of bill credits delivered to subscribers, supplemented by monetization of federal tax credits (ITC/PTC) via tax equity partnerships with firms including Foss & Company and Greenprint Capital Management. Capital is sourced through large construction and term debt facilities (most recently $600M from National Bank of Canada, RBC, and Export Development Canada in June 2026) and tax-equity structures. Revenue is recurring and contractual in nature via long-lived utility tariff arrangements, with subscriber growth and MW additions as the primary operating KPIs.

Revenue model
- Community Solar Subscriptions: Nautilus earns revenue through ownership and operation of community solar farms. Customers subscribe to receive credits on their utility bills, and Nautilus generates revenue from the electricity produced. The company benefits from tax credits (ITC, PTC), debt financing, and tax equity partnerships. Revenue is generated from the spread between cost of solar production and value of electricity credits sold to subscribers.
- Tax Equity Partnerships: Nautilus enters tax equity partnerships with investors (e.g., Greenprint Capital, Foss & Company) to monetize tax credits associated with solar development. These partnerships provide upfront capital in exchange for tax benefits, with Nautilus maintaining operational control.
