Research Project Summary Information

NYCTA Train Yard Solar Thermal Project(ST10218)

New York Power Authority,


The Pelham Maintenance Yard provides around the clock maintenance for subway trains seven days a week. One hundred and thirty employees work at the depot over three shifts. The hot water load for this depot is approximately 500 to 600 gallons per day. Hot water is currently produced in a 1,200-gallon storage tank with electric resistance heat. During the 1980s, solar collectors were installed at this depot to reduce the amount of fossil fuel used for water heating. Nevertheless, due to inherent system design problems, use of the solar system was quickly abandoned.

Project Description

The Contractor, New York Power Authority, shall install evacuated tube collectors at the New York City Transit (NYCT) Pelham Maintenance Yard. The systems design shall reuse an existing 1,200 gallon solar tank with a new brazed plate heat exchanger. The system shall be commissioned to ensure proper operation. The system’s performance shall be monitored for one year. The Contractor shall promote the benefits of this demonstration to other potential customers.


The solar thermal system will save more than 18,000 kWh annually in water heating energy consumption.
