The Gowanus & Narrows Repowering

ALPHA GENERATION

The Gowanus & Narrows Repowering

INTRODUCTION

The Gowanus & Narrows Repowering projects will modernize two legacy Brooklyn generating stations with advanced gas technology, delivering 819 MW of capacity that is more efficient, faster‑starting, and dramatically cleaner. These projects strengthen grid reliability, reduce emissions, and support New York City’s transition to a cleaner energy future.

The repowered facilities are designed to reduce emissions of key pollutants while maintaining the essential peaking capacity required for local reliability. Features include dual-fuel capability, hydrogen-ready turbines, and a reduced physical footprint that supports improved environmental conditions, including benefits to surrounding aquatic habitats.

The projects also prioritise resilience, with storm-ready, barge-mounted infrastructure designed for a constrained transmission environment critical to New York City. Alongside these operational benefits, the developments will deliver meaningful economic impact through union-led construction and a strong focus on local hiring.
