Portfolio membership follows the latest EIA-860 reporting entity. It does not imply ultimate ownership.
View full reporting portfolioNYSDEC issued Permit Review Report renewal 2 for the exact facility. The report identifies NYPA as owner and describes two GE LM6000 simple-cycle combustion turbines firing natural gas, together with two gas-fired inlet-air-heating boilers (Heatec, 7.4 mmBtu/hr each) and a diesel backup generator (746 bhp).
A 2024 clean-energy presentation reports that the Gowanus repowering proposal associated with the NYPA Joseph J. Seymour peaker was withdrawn in 2021. The available evidence does not show that repowering was constructed or that the existing turbines were retired.
