Kingspan's Solar Roof: A New Blueprint for Industrial Sustainability

MENDOTA, IL – April 09, 2026 – In a significant move that merges corporate sustainability with strategic business planning, a massive 881-kilowatt (kW) rooftop solar array has been completed atop the Kingspan Insulation manufacturing facility in Mendota, Illinois. The project, a collaboration between independent power producer REC Solar, building solutions giant Kingspan, and developer Dynamic Energy, represents a powerful new model for industrial decarbonization in America's heartland.

The sprawling 50,000-square-foot system is projected to generate approximately 1 million kilowatt-hours of clean electricity annually. This output is enough to offset an estimated 870 metric tons of carbon dioxide each year, equivalent to removing nearly 200 gasoline-powered cars from the road. The installation marks a tangible step in the evolution of manufacturing, where environmental responsibility and economic resilience are increasingly intertwined.

A Passion for the Planet, A Strategy for Business

This project is far more than a standalone environmental initiative; it is a critical component of Kingspan Group’s ambitious global sustainability program, known as 'Planet Passionate.' Launched in 2019, the 10-year strategy commits the company to aggressive targets, including achieving net-zero carbon manufacturing and powering 60% of its operations with direct renewable energy by 2030.

The Mendota installation is the company's third major solar project in North America, following a 1.05 MW array in DeLand, Florida, and a 1.36 MW system in Winchester, Virginia. This consistent investment underscores a deep-seated corporate philosophy. By the end of 2023, Kingspan had already installed solar PV systems on nearly half of its wholly-owned sites globally, making substantial progress toward its renewable energy goals.

“Bringing solar power online at our manufacturing site is a milestone of which we’re incredibly proud,” said Kyle McEnroe, President of Kingspan Insulation North America. “This project is a tangible example of our Planet Passionate commitment in action as we continue to reduce operational carbon, increase our use of renewable energy, and invest in long-term solutions that strengthen both our environmental performance and our business.”

This commitment has earned the company external validation from top Environmental, Social, and Governance (ESG) rating agencies. Kingspan currently holds a strong 'AA' rating from MSCI and is rated 'Low Risk' by Sustainalytics, reflecting its robust management of industry-specific sustainability risks and opportunities.

The Power of the PPA Partnership

The successful execution of the Mendota project hinges on an innovative partnership structure and a sophisticated financing model. In this arrangement, each partner brings specialized expertise to the table. Kingspan provides the rooftop space as the host, Dynamic Energy serves as the expert developer and engineering, procurement, and construction (EPC) firm, and REC Solar takes on the role of the long-term owner and operator as an Independent Power Producer (IPP).

Central to this collaboration is a 25-year Power Purchase Agreement (PPA). Under the PPA, REC Solar finances, owns, and maintains the solar array, selling the clean electricity it generates back to Kingspan at a predetermined, fixed rate. This model eliminates the need for Kingspan to make a significant upfront capital investment while providing long-term predictability and control over its energy costs—a crucial advantage in a market characterized by volatile electricity prices.

“As companies increasingly seek strategies to lower emissions and strengthen supply chain sustainability, this project shows how clean, reliable, and affordable solar energy -- delivered through a long-term power purchase agreement -- can help achieve those goals,” said Robb Jetty, CEO of REC Solar.

This collaborative history is well-established. REC Solar also owns and operates the solar array at Kingspan's Florida facility, while Dynamic Energy was the developer behind the Virginia project. This repeated engagement highlights a trusted, effective partnership capable of replicating success across different locations.

Oliver Davis, President and COO of Dynamic Energy, emphasized the dual benefits of this approach. “With U.S. industrial electricity rates continuing to rise, this project demonstrates how sustainability and sound business planning go hand in hand,” he stated. “We applaud their forward-thinking approach to reducing emissions while gaining control over rising energy costs.”

Energizing Illinois' Industrial Heartland

The Kingspan project is not happening in a vacuum. It is a landmark installation within a state that is actively fostering a transition to clean energy. Illinois' groundbreaking Climate and Equitable Jobs Act (CEJA), signed into law in 2021, has created one of the most progressive policy environments for renewable energy in the nation.

CEJA sets ambitious statewide targets, mandating 40% renewable energy by 2030 and 100% carbon-free power by 2045. The legislation provides a clear pathway and robust incentives for projects just like the one in Mendota, particularly for large industrial users seeking to decarbonize their operations and manage energy expenses. By enabling companies to invest in renewables, the state is attracting private investment and building a resilient, modern energy grid.

The Mendota installation serves as a powerful case study for other manufacturers in Illinois and across the Midwest. It demonstrates a viable, economically sound path to reducing carbon footprints, stabilizing operational costs, and contributing to state and global climate goals. As industrial sectors face increasing pressure to decarbonize, this synthesis of corporate leadership, innovative financing, and supportive public policy provides a clear and replicable blueprint for a sustainable industrial future.
