Reliable Clean City (Queens) Frequently Asked Questions

We’re investing approximately $800 million to upgrade electric substations and install new transmission lines that will bring renewable and reliable power to New York City.

These transmission lines will deliver hundreds of megawatts of clean energy generated by renewable sources, like hydroelectric dams, solar energy plants, and wind farms onshore and offshore, to the Big Apple.

This project represents our commitment to aggressively transition away from fossil fuels and build a resilient energy grid that delivers 100% clean, reliable energy by 2040.

We’re starting the project in Queens because we’re retiring gas turbine generators located in Astoria. In their place, we’ll install an underground transmission feeder connecting our Rainey and Corona substations.

The New York State Department of Environmental Conservation enacted air emissions regulations which have resulted in the projected unavailability of plants reliant on fossil fuels (i.e., NRG Gas Turbine Generators in Astoria) in Con Edison’s service territory creating transmission reliability deficiencies in the Queens transmission load area.

The new 300 MW transmission tie between our substations in Corona and Long Island City will address those reliability needs by connecting Queens to clean reliable energy sources located outside of New York City. Plus, by eliminating equipment reliant on fossil fuels, we’ll reduce pollution and improve the air quality.

Renewable energy sources from Upstate New York and Canada include, but are not limited to, wind farms onshore and offshore, solar power plants, hydroelectric dams, and fuel cells, which do not utilize fossil fuel resources in the process of generating electricity.

Reliable Clean City is part of our commitment to New York’s Clean Energy Standard (CES), designed to fight climate change, reduce harmful air pollution, and ensure a diverse and reliable low carbon energy supply. The expansion of the CES, so that 70% of New York's electricity comes from renewable energy sources such as solar and wind by 2030, was codified under the Climate Leadership and Community Protection Act (Climate Act).

The project represents Con Edison’s dedication to transitioning away from fossil fuels and building a resilient energy grid that delivers 100% clean energy by 2040, as outlined in Our Clean Energy Commitment.

No. You’ll still have the same, reliable power throughout the project’s duration.
The Queens part of the Reliable Clean City project begins January 2022 and will last until summer 2023.

From January 2022 until summer 2023, you may experience:

  • Construction noise from jackhammering, digging, and repaving the streets during the day
  • Temporary relocation of bike and bus lanes, as well as traffic detours
  • Temporary loss of parking spots

Most construction will take place in the day with the exception of New York City, New York State, or federal-required stipulations.

Quanta Infrastructure Solutions Group was awarded the contract to install the transmission line along the six-mile route. They have subcontracted Hallen to perform the excavation in the streets and Welsbach to install the electric transmission cable (tie).

Work inside both substations will be performed by a mix of Con Edison employees and contractors; all of the below-grade work will be performed by contractors, and above-grade electric and civil work will be split equally by Con Edison and contractors.
