Pipestone Power Project is a combined heat and power generating facility.
The Pipestone Power Project is a 32 megawatt cogeneration facility that provides power and heat to Tidewater Midstream’s 100 MMcf/day Pipestone gas plant in the Montney region in northwestern Alberta.
Two Solar Titan 130 gas turbine generators operate in parallel to meet site power requirements. Solar Titan 130 turbines utilize low dry emissions combustor technology in order to reduced emissions and enables the gas turbines to operate more cleanly.
A waste heat recovery unit (WHRU) is utilized to provide heat for process needs in the host’s gas processing facility. The single WHRU is designed to cross exchange heat from the turbine exhaust from the two gas turbines with the heat medium to be able to provide process duty for the facility. The WHRU is designed to operate with either one or both power generation units in operation and is equipped with a duct burner to provide supplementary heat when the gas turbine engines are not in operation.
Tidewater Midstream is responsible for operations and maintenance of the cogeneration facility, while Solar Turbines is responsible for major maintenance and inspection outages on the gas turbine generators.
Cogeneration, or combined heat and power, is the use of a power station to generate electricity and useful heat at the same time. Cogeneration is a more efficient use of fuel because otherwise-wasted heat from electrical generation is used to meet the thermal needs of the host facility. The use of a cogeneration process eliminates reliance on energy imported from the grid and decreases total energy cost.
