Oak Square Partners

What Oak Square Partners does

Oak Square Partners (OSP) is a privately held, full-service renewable energy developer founded in 2016 and headquartered at 60 Austin Street, Suite 301, Newton, Massachusetts. The company specializes in solar photovoltaic (PV) and battery storage project development across New England, with named offtake customers that include the Towns of Lee, Lenox, and Harvard (MA), the Norton and Stoughton Public Housing Authorities, UMass-Boston, and Winn Development. Its stated active pipeline exceeds 30 MW of solar and solar-plus-storage projects distributed across multiple states and local jurisdictions.

The company's core offering is end-to-end project development spanning site acquisition, interconnection, permitting, and construction management. Completed projects include ground-mounted, roof-mounted, and landfill-mounted solar arrays in Massachusetts and Rhode Island totaling over 5 MW of PV capacity, with the largest single installation being the 2.7 MW Douglas Pike Solar array completed in Burrillville, RI in June 2023. The underlying technology is conventional distributed-generation solar PV paired with lithium-ion battery storage; OSP's differentiated capability sits in development execution and in navigating New England's patchwork of municipal net metering rules, state feed-in tariff programs (MA SMART, RI REGrowth), and community net metering pilots rather than in proprietary hardware or software.

OSP operates a project developer business model, monetizing completed assets through direct sales to offtake counterparties under long-term (typically 20-year) net metering credit purchase agreements or feed-in tariff contracts, or alternatively through retained ownership and ongoing asset management. The firm is founder-led and bootstrapped: co-founders Sevag Khatchadourian and John Typadis launched the company with a single disclosed $595,000 financing event in August 2017, and Principal Demetri Typadis rounds out a three-person leadership group. With 1-10 employees, OSP functions as a boutique development shop whose scale of operation is constrained by capital intensity and headcount rather than by pipeline opportunity.

Direct peers

• Nexamp: Nexamp is one of the largest community solar developers in Massachusetts and New England, developing distributed solar projects with long-term net metering and community solar subscriptions. Directly competes with OSP for the same municipal, public housing, and community-solar offtake customers in Massachusetts and Rhode Island.
• BlueWave Solar: BlueWave Solar is a Boston-based solar developer and owner-operator focused on community solar and distributed generation projects across New England and other US markets. It targets the same municipal and community net metering offtake structures that OSP relies on, making it a directly comparable Massachusetts-headquartered peer.
• Borrego Solar: Borrego Solar is a large distributed-generation and utility-scale solar developer with significant operations on the East Coast. It develops ground-mounted, roof-mounted, and landfill solar arrays for C&I, municipal, and institutional customers — overlapping directly with OSP's project types and customer segments.
• Nautilus Solar: Nautilus Solar is a distributed generation and community solar developer that develops, owns, and operates solar projects in the Northeast and across the US. It competes with OSP for municipal and community solar offtake in Massachusetts and neighboring states and pursues similar net-metering and feed-in tariff structures.
• Syncarpha Capital: Syncarpha Capital is a New England-based distributed solar developer focused on community solar and net-metered projects for municipalities and businesses in Massachusetts. It competes for the same municipal net metering credit purchase agreements and community net metering offtake in OSP's core market.

Broad incumbents

• EDF Renewables North America: EDF Renewables is a large-scale, broad renewable energy developer with a distributed generation and utility-scale solar portfolio. It competes for the same municipal and institutional offtake customers as OSP in New England but operates at much greater scale and capital base across many technologies and geographies.
• Ameresco: Ameresco is a Massachusetts-based clean energy and energy efficiency company that develops, owns, and operates solar and storage projects for municipalities, public housing authorities, and institutions. It directly overlaps OSP's customer segments and net-metered municipal project model, but at much larger scale.
• Engie North America (Solar): Engie is a global energy and solar developer with significant North American distributed generation and community solar operations. As a broad incumbent, it overlaps with OSP's technology and customer base but with substantially more capital and geographic reach.

Emerging players

• Clearway Community Solar: Clearway operates community and distributed solar projects across multiple US states, including New England. As a community-solar-focused developer with subscription-based models, it competes for the same municipal and community-solar dollar as OSP, though with a different ownership/subscription structure.
• Summit Ridge Energy: Summit Ridge Energy develops and owns community and distributed solar projects across the US, including projects backed by long-term offtake arrangements. While more active in other states, it is an emerging competitor in the same distributed-solar/net-metering category that OSP operates in.
