Brooklyn Navy Yard (BNY) Cogeneration Partners Plant is a nominal 300 MW Combined Cycle Cogeneration Plant in Brooklyn, NY.  This "merchant plant" sells power to the utility grid and exports steam (generated via the gas turbine waste heat) to the Con Edison NYC steam distribution system.

Steam Plant
When BNY began to supply steam to Con Edison, Con Edison discovered that the chemical treatment in the steam was deleterious to their operation.  BNY retained LORING to review the problem.

The solution was to provide a separate water loop for the spray water system that was used to desuperheat the steam before it was supplied to the Con Edison system.  A new deaerator tank, boiler feed pumps, heat exchangers, piping and controls were provided to solve the problem.

In addition to solving the steam quality problem, the overall plant cycle efficiency increased.

Electrical Engineering
LORING was retained to provide engineering design services for the upgrade of the electrical distribution system.

The electrical upgrade was the first in a series of improvements to take place over an estimated ten year period. The substation, originally commissioned in the early 1940’s as one of eight 13.8/2.4 kV distribution substations, served the needs of the Brooklyn Navy Yard until 1991. A transformer fire destroyed all of the electrical switchgear and a majority of the building structure.

Project equipment included a new 13.8 kV switching station; one 13.8 kV/480 volt substation; six 13.8 kV/208 volt substations; a 13.8 kV, six megawatt diesel generator plant (three 2000 KW generators); and underground, 13.8 kV ductbank feeders. A new building was constructed to house this equipment.
