How it reaches New York City
-
Mayor Zohran Mamdani and Governor Kathy Hochul announced a plan to study a "Thermal Energy Network" that would use thermal energy to cool subway stations and store that heat for winter use. Separately, reports indicate that a $77 million state fund intended for extra NYPD officers in the subway system was exhausted by July. Consequently, the Mamdani administration must now cover the costs of these added patrols.

If the feasibility study is successful, design work on the technology will begin in 2027. The system is designed to make subway stations tolerable during summer—addressing issues like the Brooklyn Bridge station reaching 96 degrees—and to transfer heat through geothermal boreholes to warm nearby municipal buildings during winter.
No report states this step directly. Brind drew it from the reporting on each side of it, so treat it as an informed guess.

The facts so far
As reported. Each one links to where it comes from.
- The feasibility study to explore the Thermal Energy Network will cost $800,000.gothamist.com
- The study will focus on the Brooklyn Bridge-City Hall and Chamber Street station complex.gothamist.com
- The goal is to capture heat to warm nearby municipal buildings come wintertime.gothamist.com
- The Brooklyn Bridge station reached 96 degrees on average during the summer months.gothamist.com
Why it matters
The extreme heat within New York City's subway system poses a significant challenge to millions of commuters, making the transit experience uncomfortable and potentially hazardous during summer months. This plan represents a major attempt to apply cutting-edge climate technology to solve a long-standing infrastructure problem.
This initiative is part of a broader effort to modernize the city's public services and infrastructure. By exploring how to harness and transfer thermal energy, the city aims not only to improve the daily lives of riders but also to increase the energy efficiency of critical municipal buildings.
