New York’s Sugar Hill community solar farm testing real-time optimal power flow software

National Grid CEO John Pettigrew and National Grid US President Badar Khan; CJ Colavito, VP, Engineering, Standard Solar; U.S. Light Energy COO Mike Fingar and CEO Mark Richardson.

On June 16, Latham, NY based community solar developer U.S. Light Energy, along with its partner Standard Solar hosted the CEO of National Grid John Pettigrew and the utility’s US President Badar Khan on a tour of the Sugar Hill Community Solar Farm.

The Sugar Hill Community Solar Farm is one of the first two sites nationwide to host a pilot project utilizing the Real-Time Optimal Power Flow (RT-OPF) software platform, designed to model, monitor and coordinate the local power grid and local distributed generation facilities, like community solar farms, that feed power into the grid. These controls become more and more important as new distributed generation facilities come online, as we move towards a renewable energy infrastructure that relies on a larger number of generation systems feeding power into the grid from multiple locations.

Serving National Grid customers in the NY Capital Region, the Sugar Hill Solar Farm is the first community solar farm developed in Clifton Park, NY. The 7.125-MW ground-mount solar array is located on 40 acres of land and encompasses nearly 20,000 solar modules. In operation since early 2020, it produces more than 6.7 million kWh of clean energy annually.
