Castillo Engineering and Northern Sun Energy Expand New York Community Solar with Three New Projects

Castillo Engineering and Northern Sun Energy (NSE) have been awarded three new community solar projects in Kinderhook, Wilton, and East Greenbush, New York, marking the continued success of their partnership in advancing clean energy solutions. Awarded by Seaboard Solar, these projects total 31.49 MWdc and will generate local renewable power for thousands of homes, while reinforcing New York’s leadership in community solar deployment.

This expansion follows the successful commissioning of the 5 MW Troy project, which Castillo Engineering and NSE completed together from initial design to final interconnection. The strong working relationship between the companies has led to continued collaboration, securing additional projects in the state.

Each of these new projects presents unique engineering challenges. Wilton and East Greenbush feature uneven terrain, requiring a carefully planned balance-of-system approach to manage the distance between arrays and interconnection points. Additionally, strict voltage drop requirements meant Castillo Engineering had to find cost-effective design solutions, ensuring compliance without unnecessarily increasing project costs.

“New York continues to lead the way in community solar, and we are proud to contribute to that growth with Northern Sun Energy and Seaboard Solar,” said Christopher Castillo, CEO of Castillo Engineering. “These projects required innovative engineering solutions to balance technical constraints and cost-effectiveness, and our team worked closely with NSE to optimize designs without sacrificing efficiency.”

“We’re excited to continue working with Castillo Engineering on these latest projects,” said Chris Balogh, Managing Partner at NSE. “Their expertise in optimizing system design has been invaluable in keeping our projects efficient and cost-effective while ensuring seamless execution.”

As New York continues to expand its nation-leading community solar program, these projects will provide affordable, locally generated clean energy to residents and businesses. Castillo Engineering, Northern Sun Energy, and Seaboard Solar's combined efforts will ensure cost-effective, high-quality solar installations that benefit both developers and communities.

“This collaboration between Northern Sun Energy, Castillo Engineering, and Seaboard Solar is a testament to the trust and expertise built across our teams,” said Shawn Brazo, President of Seaboard Solar. “These projects will deliver reliable, clean power to local communities while supporting economic growth through job creation and increased energy independence.”
