Bethlehem Energy Center is an operating natural-gas-fired combined-cycle electric generating facility located in Glenmont, Albany County, New York, on the west bank of the Hudson River approximately three miles south of Albany. The plant entered commercial service in July 2005 and replaced the predecessor Albany Steam Station on the same site. GB II New York LLC, an indirect subsidiary of Alpha Generation, LLC, owns and operates the facility. The plant is interconnected with the New York Independent System Operator (NYISO) grid at 115 kV. Its configuration consists of three GE 7FA combustion-turbine generators, three Nooter/Eriksen heat-recovery steam generators, and one GE D11 steam-turbine generator, yielding four generating turbine-generator units with reported nameplate capacity of 817 MW summer rating. The facility has an 83-acre site and uses natural gas from Dominion Transmission and Tennessee Gas Pipeline, with Hudson River water for its hybrid wet/dry cooling system. The plant participates in NYISO wholesale markets as a mid-merit merchant generator and has been subject to an interconnection uprate request.

- 2002-10 — Construction schedule revised to Q2 2005
  After considerable on-site work, PSEG revised the estimated completion date of the repowering project to the second quarter of 2005 for reasons of financial prudence. A later technical account reported the total project cost as $500 million.

## Data quality

- The plant-specific capacity measurements report 817 MW (summer rating, DOE 2025), 835 MW (NYPSC 2022 transaction), and 875 MW (NYISO uprate request, pending). The 817 MW summer rating from the DOE source is retained in the facts section as the most recent authoritative reference. These represent different measurement bases (nameplate, summer, operating) rather than conflicting values. The original-site acquisition date is reported as October 1999 by one contemporaneous construction report and as 2000 by a later engineering profile; both identify PSEG as the acquirer and Niagara Mohawk as the predecessor site owner. The October 1999 date is more specific and appears in a contemporaneous source. The reported $400 million (contemporaneous 2002 groundbreaking press) and $500 million (later 2006 technical account) are construction/project-cost figures, not confirmed debt financing amounts. No project-finance lender, debt instruments, or tax-equity structure was identified in the candidate research. The documented post-2005 expansion signal is NYISO uprate request CR24-1003 (875 MW). The evidence does not establish that the proposed uprate was completed. No retirement of Bethlehem Energy Center itself was identified through April 17, 2026. The plant was originally described as 750 MW nominal (July 2005) with supplementary HRSG firing capability to 763 MW. The summer rating of 817 MW reflects evolved rating bases and potential subsequent uprates. GE supplied both combustion turbines (reported as 7FA in technical literature, 7F.04 in project profile, each ~164 MW) and the steam turbine (D11, ~263 MW). Designation variance (7FA vs. 7F.04) reflects source-dependent nomenclature and does not indicate conflicting equipment.
