Alliance Energy Group affiliate wants to buy shut cogen in Colorado

Greeley Energy Facility LLC applied Oct. 13 with the Federal Energy Regulatory Commission for approval of its planned acquisition of an existing qualifying cogeneration facility (QF) and related assets in Colorado from Thermo Greeley LLC.

The company asked for an expedited FERC review and approval by Nov. 10.

Thermo Greeley, the seller, owns a 35-MW (nameplate) gas turbine cogeneration facility located in Greeley, Colorado. The Greeley Facility is interconnected to the transmission system owned by Public Service Co. of Colorado (PSCo). It has been mothballed since 2011, with the expiration of a power purchase agreement with PSCo.

Thermo Greeley, is owned by Stark Thermo LLC, which, in turn, is owned by certain private investment funds that are affiliates of Stark Investments.

The buyer, Greeley Energy Facility (GEF), was formed in 2015 and currently holds no assets. GEF is wholly-owned by an individual investor. Aside from the holdings in GEF, the investor owns Alliance Energy Group LLC (AEG). Through subsidiaries, AEG is engaged in electric power generation, natural gas exploration, production and transportation, and energy technology research into various forms of renewable fuels such as biodiesel and hydropower.

AEG owns 100% of the membership interest in Alliance Energy New York LLC (AENY), which owns, directly and indirectly, 100% of the partnership and membership interests in:

  • Allegany Generating Station LLC, which owns a 67-MW gas-fired combined-cycle plant located in Hume, New York;
  • Carthage Energy LLC, which owns a 62.9-MW dual fuel (gas/oil) combined-cycle cogeneration facility located in Carthage, New York;
  • Lowell Cogeneration Co. LP, the owner of a 32.5 MW (nameplate) facility located in Lowell, Massachusetts;
  • Power City Partners, the owner of a 103.1 MW (nameplate) facility located in Massena, New York;
  • Seneca Power Partners LP, the owner of a 67.3 MW (nameplate) facility located in Batavia, New York;
  • Sterling Power Partners LP, the owner of a 67.3 MW (nameplate) facility located in Sherrill, New York; and
  • AG-Energy LP, which owns a 99.3 MW electric generation plant in Ogdensburg (the “Ogdensburg Plant”) that is no longer in service.

Allegany, Carthage, Lowell, Power City, Seneca, Sterling, and AG-Energy have each received authority to sell power at market-based rates from the commission. The output of the Allegany, Carthage, Power City, Seneca and Sterling facilities are sold into the New York ISO market. The output of the Lowell facility is sold into the ISO New England market.

The application noted that two of the three generators at Ogdensburg that had been rated at 48.8 MW and 23.6 MW respectively have been retired and physically removed from the site. The third remaining generator with a rating of 26.9 MW has been taken out of service. The output of the Ogdensburg facility was previously sold into the NYISO market. However, the facility has not generated electricity since 2007 and is not currently capable of generating power, but under a steam delivery agreement provides steam to the St. Lawrence Psychiatric Center of the New York State Office of Mental Health using auxiliary boilers.
