Louth Callan Renewables breaks ground on 27 MW solar project in New Hampshire; commissioning targeted for Q3 2026

Louth Callan Renewables (LCR) has officially commenced construction on a 27-megawatt (MW) solar energy project in New Hampshire, with site mobilization beginning in mid-July 2025. The announcement was made on July 21 through a press release issued by the company. The project designates LCR as the engineering, procurement, and construction (EPC) partner, and final commissioning is scheduled for the third quarter of 2026.

This development reinforces Louth Callan Renewables’ standing as a key player in utility-scale renewable infrastructure across the northeastern United States. The solar installation, which will be connected to ISO New England’s power grid, is part of a growing wave of regional efforts aimed at strengthening clean energy supply while reducing reliance on fossil fuel imports. Civil construction began in recent weeks in collaboration with Brooks Construction, with engineering layout, permitting, and procurement already well underway.

How does this project align with New Hampshire’s clean energy trajectory?

While New Hampshire has historically lagged behind its neighboring states in large-scale solar adoption, the momentum has shifted in recent years. The state’s updated energy strategy emphasizes the deployment of distributed and utility-scale solar systems as a core component of its decarbonization pathway. This aligns with ISO New England’s broader regional grid planning framework, which seeks to integrate more renewable capacity while ensuring grid reliability.

The Renewable Portfolio Standard (RPS) for New Hampshire mandates that at least 25.2% of electricity sold by retail suppliers must come from renewable sources by 2025, a target that becomes more ambitious with each passing year. Projects like the one spearheaded by Louth Callan Renewables are essential in helping utilities and municipalities meet these obligations without significantly increasing ratepayer costs. Regional policy analysts have noted that the relatively flat permitting costs and land availability in parts of New Hampshire make it an attractive zone for future solar growth.

What responsibilities is Louth Callan Renewables managing on-site?

LCR is overseeing the complete lifecycle of the project under its role as the EPC contractor. This includes detailed engineering layout optimization tailored for site-specific topography and solar irradiance. The company is also coordinating the procurement and delivery of photovoltaic modules, inverters, racking systems, and other balance-of-system components, ensuring compliance with New England’s interconnection standards.

Environmental compliance is being addressed through an extensive stormwater control program, which is a key regulatory focus for utility-scale installations in the Northeast. LCR’s safety team is implementing protocols under its nationally recognized OSHA-compliant framework, including mandatory hazard communication, fall protection, and heat illness prevention standards.

Mechanical and electrical builds will be sequenced using LCR’s proprietary construction flow model. According to the company, this model reduces material laydown congestion, minimizes idle labor time, and ensures that field teams can transition smoothly from pile-driving to module installation to electrical wiring. In the final stages, LCR will manage ISO New England’s rigorous commissioning and acceptance testing procedures to bring the project fully online.

What did the company’s leadership share about the build?

Nick Sylvestre, Founder and CEO of Louth Callan Renewables, stated that the company had invested considerable engineering effort into optimizing the project for both constructibility and long-term asset value. He emphasized that the LCR team had collaborated closely with the asset owner to refine technical specifications in a way that ensures delivery is not only on time but also economically efficient.

Sylvestre said: “We’re excited to bring our construction expertise to another large solar project in the New England region. Our team has worked hard to value engineer the project to help the owner make it a buildable and valuable asset. Now we’re focused on executing a clean, safe, and high-quality build that reflects our commitment to industry best practices and community engagement.”

Though LCR has not publicly disclosed the financial value of the contract or the identity of the asset owner, the firm is known for handling utility-scale EPC scopes ranging from 20 MW to over 150 MW in recent years. Company officials have suggested that this project fits squarely within LCR’s preferred project profile: technically demanding, environmentally sensitive, and logistically complex.

How does this project position LCR in the broader EPC solar market?

Louth Callan Renewables is part of a rising class of EPC firms specializing in mid-scale solar projects across emerging clean energy markets in the U.S. Northeast and Mid-Atlantic regions. Headquartered in Enfield, Connecticut, LCR has built out a portfolio of solar and storage facilities, including grid-tied and behind-the-meter applications. Its differentiation lies in its streamlined build processes, deep permitting expertise, and modular sequencing models that are adapted to difficult geographies.

With the U.S. Inflation Reduction Act (IRA) extending clean energy tax credits through the next decade, demand for EPC partners with proven delivery records has surged. Industry analysts have noted a growing shortage of construction labor, permitting specialists, and interconnection consultants in the sector — conditions that favor experienced firms like LCR.

In addition, regional utilities are increasingly issuing solicitations for renewable buildouts that require accelerated timelines and pre-permitted EPC partners. LCR’s ability to manage civil, mechanical, and grid commissioning scopes in-house has positioned it as a preferred partner for developers and asset managers operating in New England’s challenging terrain.

What comes next for the New Hampshire project?

Construction will proceed over the next 12 to 14 months, moving through the electrical buildout and module installation phases before entering the quality control and testing window. LCR will coordinate closely with utility interconnection teams to synchronize final system checks with ISO New England’s operational protocols.

The company has indicated that the project’s procurement strategy includes U.S.-compliant equipment to qualify for domestic content tax incentives, although specific vendors were not disclosed. LCR has also confirmed that job site staffing is expected to ramp up significantly in late Q3 2025, with peak workforce levels reaching over 100 on-site personnel during major installation phases.

If timelines are met, the 27 MW system will be ready to deliver clean electricity to the New England grid by fall 2026, contributing to grid stability and helping offset the region’s fossil generation mix.

As of now, no major delays or permitting issues have been reported. The project remains on track and stands as a strong example of how regional solar development is scaling to meet state-level climate mandates without sacrificing project quality or timeline discipline.
