Greeley Energy plans to revive shut 30-MW plant in Colorado

Greeley Energy Facility LLC, which plans to revive a shut power plant in Colorado, applied Dec. 22 at the Federal Energy Regulatory Commission for authorization to make sales of electric energy, capacity and ancillary services at market-based rates.

On Oct. 3, 2015, Greeley Energy Facility (GEF) filed an application for commission approval to acquire an approximately 30-MW, gas-fired turbine facility located in the City of Greeley, Weld County, Colorado, from Thermo Greeley LLC. The Greeley Facility is located in the Public Service Co. of Colorado (PSCO) balancing authority area. That application is still pending.

GEF was formed for the purpose of consummating this transaction. The Greeley Facility has been mothballed since the expiration of a power purchase agreement in 2011. Upon its return to service, GEF said it will sell its output pursuant to the blanket authorization requested in this application.

GEF is wholly-owned by Alliance Energy West LLC, which in turn is owned by an individual investor, Samuel G. Nappi. Aside from the holdings in GEF, Nappi 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 wholly-owns Alliance Energy New York LLC (AENY). AENY owns, directly and indirectly, 100% of the interests in:

  • Allegany Generating Station LLC, which owns a 60 MW (summer rating) gas-fired combined-cycle power plant in Hume, New York;
  • Carthage Energy LLC, which owns a 59.2 MW (summer rating) dual fuel (gas/oil) combined-cycle cogeneration facility in Carthage, New York;
  • Power City Partners, the owner of a 83 MW (summer rating) natural gas, fuel oil, and biofuel-fired combined-cycle facility in Massena, New York;
  • Seneca Power Partners LP, the owner of a 56.7 MW (summer rating) facility in Batavia, New York;
  • Sterling Power Partners LP, the owner of a 55.9 MW (summer rating) facility in Sherrill, New York; and
  • AGEnergy LP, which owns a 23 MW (summer rating) plant in Ogdensburg, New York, that is no longer in service.

AENY also owns Lowell Cogeneration Company LP, the owner of a 28.5 MW (summer rating) natural gas and fuel oil-fired combined-cycle facility in Lowell, Massachusetts. However, the Lowell Facility was retired in September 2013.

Allegany, Carthage, Power City, Seneca, Sterling, AG-Energy and Lowell 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 was sold into the ISO New England market.

In addition to AENY, AEG also owns 100% of the membership interest of Alliance NYGT LLC, and indirectly, 100% of the membership interest of AER-NYGen LLC. Alliance NYGT owns the 33.1 MW (summer rating) Hillburn Gas Turbine located in Hillburn, New York, and the 33 MW (summer rating) Shoemaker Gas Turbine in Middletown, New York. AER NY-Gen currently holds no assets. Alliance NYGT is authorized to sell power at market-based rates and the output of the Hillbum and Shoemaker facilities is sold into the NYISO market.
