Con Edison, 174 Energy International Creating Queens Battery Storage Undertaking

Con Edison, 174 Power Global Developing Queens Battery Storage Project

Con Edison and 174 Power Global have reached an agreement to install New York’s largest battery storage project at an industrial site in Astoria, Queens.

The battery can discharge 100 MW of electricity. 174 Power Global, specializing in renewable energy projects, will build and own the battery system on 20th Avenue near the East River on New York Power Authority property that used to be the former Poletti Power Plant.

The companies have a seven-year contract under which Con Edison brings electricity from the battery system to the state wholesale market. At the end of the contract, 174 Power Global will route the electricity into the state’s mass flow transmission system.

“Supply-scale battery storage will play an important role in New York’s clean energy future – especially New York City – where it will help maximize the benefits of offshore wind power,” said Tim Cawley, president of Con Edison. “This project with 174 Power Global will help displace fossil fuel generation when electricity needs are highest.”

East River’s 100 MW / 400 MWh-hour energy storage system will contain enough power to power the World Trade Center for about a day. The batteries are charged from the grid at times when the electricity demand is low and cheaper. They are discharged at times when electricity demand is high, which reduces the electricity demand from fossil fuel plants.

Battery technology has improved significantly over the past few years and is an important part of New York’s environmental plans. The State Climate Leadership and Community Protection Act provides that 70% of the state’s electricity will come from renewable sources by 2030 and recognizes the need to use energy storage to offset the interruption in renewable energy production – the project fits in well with the one ahead Adding large amounts of renewable energy to the state’s portfolio, including 9,000 MW from offshore wind turbines.

174 Power Global is responsible for obtaining approval to build and operate the project by the end of 2022. The batteries are in dozens of containers and are connected to a nearby Con Edison substation. The batteries cause no emissions and little noise. 174 Power Global won the project by responding to a call for proposals published by Con Edison in July 2019.
