The New York State Department of Environmental Conservation is taking comment until Aug. 12 on a draft air permit that would limit the oil used by Brooklyn Navy Yard Cogeneration Partners LP as a back-up fuel.
The Brooklyn Navy Yard Cogeneration Plant is a 286-MW gas-fired facility. It consists of two Siemens V84.2 gas turbines, capable of firing natural gas or fuel oil. Each turbine is equipped with a Heat Recovery Steam Generator (HRSG). Each turbine may operate independently of the other. Both turbines have water or steam injection capability for power augmentation on natural gas and water injection for NOx control on fuel oil.
The plant supplies electricity to Consolidated Edison and the Navy Yard, and supplies steam to Con Edison, the Navy Yard and the Red Hook Water Pollution Control Plant.
This permit modification is to limit the use of back-up fuel oil to a maximum of 16.74 million gallons per year during the periods of curtailment and supply interruptions of the primary fuel, which is natural gas. The facility will continue to maintain and comply with the facility-wide NOx emissions cap of 145.77 tons per year as prescribed in the previous permit. The application does not seek to modify any other short-term or long-term permit limit. The facility is required to use ultra low sulfur distillate (USLD) oil with a sulfur content no greater than 0.0015% by weight beginning July 1, 2016.
