Carson Cogeneration Company, a California Limited Partnership
Carson Cogeneration Company (CCC), located on 1.4 acres in Carson, CA is a 50MW natural gas fired combined cycle cogeneration plant that began operations in 1990. It uses a 45.8 MW General Electric LM6000PC gas turbine, a Vogt unfired heat recovery steam generator, a 10.5 MW Shin Nippon steam turbine, and previously exported thermal energy using a Trane steam powered single stage lithium bromide 800 ton absorption chiller in support of ice production. The previous Power Purchase Agreement (PPA) consisted of the plant selling electricity to Southern California Edison (SCE) and selling thermal energy to Mountain Water Ice Company (MWIC). CCC modified the PPA with SCE and converted the CCC PPA to a dispatchable Combined Cycle Exempt Wholesale Generator. CCC no longer has an obligation to sell steam to MWIC. This modified PPA expires in February 2020. CCC is operated and managed by Energy Operations Group, LLC. In addition to the changes in the PPA and operation of the plant we have evaluated all service contracts at CCC and moved toward more cost effective service providers.
EOG is working on redevelopment of the CCC facility into a 100 MW simple cycle operation. SCE is receptive to renegotiating the CCC PPA. EOG has suggested converting the CCC facility to a simple cycle operation and adding an additional LM6000 or removing the existing plant assets in their entirety and replacing it all with a nominal 100 MW General Electric LMS100. EOG has determined that the natural gas supply is adequate and the CCC air permit is sufficient to operate a 100 MW peaking operation up to 2500 hours per year at this location. EOG is actively seeking a development partner to realize the expansion and conversion of CCC into a peaking plant.
The CCC opportunity would consist of an investment in a new project company that has rights to purchase the CCC facility and fund the redevelopment through a formal assessment of the interconnection status, air permit determination, water requirements, natural gas interconnection and supply, equipment selection and PPA negotiations. An operating model and a budget for this opportunity is available upon execution of a NDA.
Both SCE and San Diego Gas and Electric have significant long term capacity needs due to the shutting of San Onofre Nuclear Generating Station as well as need to replace the capacity lost due to the shuttering of the once through cooling generation located in the Los Angeles basin. Current opportunity could be bilateral negotiations or through a Request For Offer (RFO) processes.
Rupert Cogeneration & Glenns Ferry Cogeneration
Rupert Cogeneration Partners, Ltd. (RCP) in Rupert, Idaho, and Glenns Ferry Cogeneration Partners, Ltd. (GFCP) in Glenns Ferry, Idaho are sister 10 MW natural gas fired combined cycle cogeneration plants that began operations in 1996. Each plant consists of a double ended generator powered at one end by a Solar Turbines Mars 100S gas turbine engine and at the other end by a steam turbine driven through a self-actuated clutch. An unfired heat recovery steam generator transfers heat from the turbine exhaust to water to create steam which is provided to the thermal host and the steam turbine. The Glenns Ferry plant make up water is supplied at elevated temperature from a geothermal well. The thermal host both Idaho Fresh-Pak plants are provided steam at an average rate of 30,000 pounds per hour at Rupert and 20,000 pounds per hour at Glenns Ferry in support of potato processing operations. Solar Turbines was the engineering, procurement, and construction contractor for both projects. Idaho Energy Operations Group, LLC (IOG), and affiliate of EOG, of Park Ridge, Illinois (near Chicago) operates bothtwo plants.
The City of Rupert Idaho (Rupert) has made inquiry on the future of RCP, specifically since there is a need for grid support in Rupert as well as throughout the south central part of Idaho. The discussions have advanced to United Electric Cooperative and Utah AMPS. We believe that a combination of these entities would be interested in acquiring or contracting RCP’s continuing output
The Glenns Ferry equipment is in place and being maintained. It could be either sold in place and run by the new owner or could be redeployed into a process that required 10 MW and a steam supply upwards of 40,000 per hour of 150 psi steam. The plant ran a total of ten years and is in excellent condition.
Mojave Illinois Holdings, LLC (MIH) completed the acquisition of the Mojave cogeneration power plant on August 9, 2011. The plant is operated by Lake Shore Mojave, LLC ("LSM") and is a 55MW, natural-gas fired, combined cycle, cogeneration plant that began commercial operations in July, 1990. The plant is located on approximately four acres in Boron, California. It consists of one natural gas-fired Westinghouse 251 B-10/12 combustion turbine rated at 41 MW, one Nooter-Erickson unfired heat recovery steam generator (HRSG) with high pressure and low pressure sections that supplies a Westinghouse Model M33 automatic extraction condensing steam turbine generator rated at 15.5 MW. The HRSG houses a Selective Catalytic Reduction system for Nitrogen Oxides reduction. Plant cooling is provided by a two-cell, forced draft, wet cooling tower. LSM ceased operation on August 5, 2013. When LSM was operating it as a Qualifying Facility as defined under the Public Utility Regulatory Policies Act of 1978. The plant sold power to Southern California Edison Company under a power purchase agreement and sold intermediate pressure steam to United States Borax & Chemicals under a Thermal Use Agreement for use in their borate processing operations. MIH and LSM are managed by Chicago area-based Lake Shore Energy Operations Group, LLC, of which Energy Operations Group, LLC is the majority owner.
LSM is in the process of banking the emissions credits and developing a peaking plant in East Kern County. Many California based utilities have been required to divest their solid fuel generation in other states opening up transmission which will allow a generator in Kern County to serve the Los Angeles Basin.
Thermo Power and Electric, LLC
EOG principals purchased the Thermo Power & Electric, LLC (TPE) facility on March 7, 2014. The facility is a combined cycle cogeneration facility located on The University of Northern Colorado’s (UNC) Greeley, Colorado campus. The plant is powered by two General Electric LM5000 gas turbines which exhaust through two Vogt three stage heat recovery steam generators which in turn power a Westinghouse Canada 16.4 MW steam turbine. The total output of the plant is 72 MW at peak. This plant is currently being redeveloped to provide generation for the electric grid and provide thermal energy to UNC. There is a below market long term natural gas contract in place with Atmos to deliver to the TPE site. The facility is interconnected with Public Service of Colorado at 115 kV.
TPE was purchased as a redevelopment opportunity where the purchase price and an above average return were to be expected when the plant equipment was sold.
UNC is very interested in developing a replacement project on their campus to provide thermal energy to the university and sell electricity to the local utilities.
Shaokatan Hills & Lakota Ridge
EOG principals purchased 100% of Shaokatan Hills and Lakota Ridge wind farms on December 31, 2012. Each project went commercial in 1999 and is contracted with Northern States Power, a subsidiary of Xcel Energy.
Lakota Ridge consists of 15 NEG Micon NM48 750 kW Turbines, NEG Micon was purchased by Vestas in the 2002 timeframe. The total output of Lakota Ridge is 11.25 MW. EOG provides the asset management to this project along with operations and maintenance oversight.
Shaokatan Hills consists of 18 Vestas V47 660 kW Turbines. The total output of Shaokatan Hills is 11.88 MW. EOG provides the asset management to this project along with operations and maintenance oversight.
CRT anticipates the restructuring of the PPA with Northern States Power within the next five years.
