Northern Sun Energy

What Northern Sun Energy does

Northern Sun Energy is a privately held, utility-scale solar and battery energy storage Engineering, Procurement, and Construction (EPC) contractor. The firm delivers turnkey services — Full Turnkey Installation, Engineering and Procurement, and Construction Management — for utility-scale solar farms and Battery Energy Storage System (BESS) projects. It is headquartered in Kissimmee (Orlando area), Florida, with a secondary office in Burlington, Ontario, and operates across multiple U.S. states including Florida, Louisiana, Maine, New York, Illinois, and Massachusetts following its December 2025 entry into the MISO market.

The core offering is project-based EPC delivery. Customers include project developers and owners, independent power producers (IPPs), utilities, industrial behind-the-meter buyers, and U.S. government/military clients. Active or completed engagements reference Duke Energy, Con Edison Renewable, Algonquin Utilities, the U.S. Army at Fort Polk (Louisiana), Prysmian (Illinois), Poland Spring (Maine, via Onyx Renewables), Doosan, and PowerFlex, alongside co-development relationships with Castillo Engineering, Corvias, Velarium Energy (formerly CRC Innovations), and Onyx Renewables. The company describes combined leadership experience of over 2 GW of solar and 250+ MW of battery storage, with leadership team personnel including Master Electricians (Kevin Ritzmann, Jeff Hagberg) and a P.Eng. Electrical Engineer (Chris Balogh).

The business model is project-based EPC services revenue, earned under multi-year contracts on a fixed-price or cost-plus basis with project-specific quotations. The go-to-market is direct enterprise field sales only — no channel, reseller, or self-serve motion. The company completed roughly 2+ GW of related work historically at the executive level, was running ~80 MW under construction across four states in 2025, and publicly targets nearly 100 MW in 2026. In 2025 it deployed Acumatica cloud-based ERP to support scaling, and in January 2026 it executed a planned presidency transition from Chris Balogh to Kevin Ritzmann, who joined as VP and Managing Partner in August 2025.

Expansion highlights5 records

Direct peers

• SOLV Energy: One of the largest dedicated utility-scale solar EPCs in North America, with deep BESS and high-voltage capabilities. Directly comparable to Northern Sun as a solar + storage EPC serving developers, IPPs, and utilities, though at substantially greater scale.
• Mortenson Construction: Major EPC contractor with a leading utility-scale wind, solar, and BESS practice. Comparable to Northern Sun as a turnkey EPC for renewable developers across the US, though much larger in headcount and project size.
• Swinerton Renewable Energy: Utility-scale solar and storage EPC business within Swinerton Builders. Directly competes with Northern Sun on turnkey PV and BESS construction for developers and IPPs across the US.
• McCarthy Building Companies (Renewables): National builder with a dedicated Renewable Energy + Storage group executing utility-scale solar EPCs. Overlaps with Northern Sun's customer base (developers, utilities) and turnkey delivery model.
• Primoris Renewable Energy: Clean energy and infrastructure EPC contractor with utility-scale solar and BESS projects across North America. Competes head-to-head with Northern Sun for developer and IPP EPC contracts.
• IEA Constructors (MasTec Renewables): MasTec's renewables construction arm and a long-standing utility-scale solar EPC serving developers and utilities. Directly comparable to Northern Sun's EPC services portfolio for PV and BESS projects.

Broad incumbents

• Quanta Services (Blattner Energy / Renewables): Through its acquired renewables platform (formerly Blattner/D.H. Blattner), Quanta is a top-tier utility-scale solar, wind, and BESS EPC. Comparable to Northern Sun's core offering but at multibillion-dollar parent scale with broader infrastructure scope.
• EDF Renewables North America: Major IPP and solar + storage developer that self-performs project development and often contracts with EPC firms like Northern Sun. Comparable customer-side relationship; not a direct EPC rival but operates in the same utility-scale solar market.
• RWE Clean Energy: Large IPP/developer with significant utility-scale solar and BESS pipeline in the US. Comparable market participation as a buyer of EPC services and as a developer competitor to Northern Sun's developer/IPP clients.

Emerging players

• Hanwha Qcells USA (EPC / Development): Vertically integrated module manufacturer expanding into utility-scale solar development and EPC in the US. Overlaps with Northern Sun's utility-scale PV EPC scope and increasingly BESS, especially on behind-the-meter industrial projects.
