Samuel A. Carlson Electric Generating Station, EIA plant 2682, is a municipally owned and operated thermal generating facility located at 136 Steele Street in Jamestown, Chautauqua County, New York. The station is owned and operated by the Jamestown Board of Public Utilities and serves the NYISO system. The facility comprises natural-gas steam-turbine units and a natural-gas-fired combustion turbine with combined nameplate capacity of approximately 96.3 MW. The station supports both local electric service to the Jamestown franchise territory and grid export through the Dow Street intertie over National Grid lines to NYISO. It is one of the oldest municipally operated power plants in the United States, with origins tracing to 1891 municipal generation and current facilities constructed in 1951.

## Timeline

- 1891 — Municipal generation begins
  JBPU first began generating electricity in 1891; the municipal utility subsequently developed into the operator of the Carlson station.

- 1984 — District-heating capability added
  The former coal-fired Carlson facility was modified to enable simultaneous generation of electricity and hot water for district heating.

- 2007-04-13 — Natural-gas package boiler authorized
  A New York State Department of Environmental Conservation permit modification authorized installation and operation of a new approximately 73.5 MMBtu/hour natural-gas package boiler to provide a fourth source of hot water and redundancy for the district-heating system.

## Data quality

- The exact asset is tied across the records to EIA plant ID 2682, NYISO/JBPU utility identifiers, the 136 Steele Street address, and DEC Facility ID 9060800053. Capacity figures differ by source and configuration: EIA-derived unit nameplates total approximately 96.3 MW; the LM6000 is reported at approximately 43 MW simple-cycle; the NYSERDA study reports approximately 78 MW for a particular combined operating configuration (likely LM6000 + steam turbines); and the owner reports 40–58 MW generation capability using the gas turbine. The station's historical fuel description changed over time: earlier records describe coal-fired boilers, while later records document conversion to natural gas, including the 2001 LM6000 project. The facility currently operates on natural gas but retains coal-handling infrastructure and four coal boilers (three operational per DEC permit). The $185,000 pipeline tap ($160,000) and installation ($25,000) amount is expressly treated as Nornew infrastructure financing and should not be interpreted as station acquisition consideration or power-project financing. is documented as the original equipment manufacturer of the steam turbines and has provided field engineering services; GE (General Electric and its successor divisions, including GE Vernova) is a diversified manufacturer whose product lines serve the station. Natural-gas delivery to the station is provided through the Tennessee Gas Pipeline Company main, with Douglas Pipeline as operator as of 2019 (when JBPU purchased the pipeline from Emkey Gathering). No documented acquisition transaction, change of control, portfolio transaction, third-party financing, or power-purchase agreement involving the exact station was identified in the candidate research.
