New York State, New York City and the Metropolitan Transportation Authority (MTA) are studying whether a thermal energy network (TEN) could be used to reduce temperatures on subway platforms in Lower Manhattan and transfer excess heat to nearby municipal buildings. Brooklyn Bridge-City Hall recorded average platform temperatures of 96°F (35.6°C) during summer 2025, making it one of the hottest stations in the New York City subway system. The study will also examine the potential energy savings for New York City and determine how much cooling the system could provide. The MTA and city authorities will assess whether the approach can be adapted to the conditions of a subway system. New York Governor Kathy Hochul said: For years, New Yorkers have suffered through sweltering summer heat on subway platforms, with seemingly no hope for a cooler ride in sight.
