Cogeneration & Power

We want the highest efficiencies on every power project we design.

Our expertise extends to cogeneration and power projects, 100 MW and less. Rangeland’s team is experienced in the design, operations, commissioning and maintenance of cogeneration integrated into process facilities. Combined heat and power plants are typically embedded close to the end-user and therefore help reduce transportation and distribution losses, improving the overall performance of the electricity transmission and distribution network.

Rangeland can add value and minimize environmental impact with the following cogen and power activities

  • Cogen auxiliary systems

  • Peak shaving

  • Refurbished turbines fueled by sour gas solutions or gas production

  • Process integration (electrical, HRU and heat medium integration, and process control)

  • Surplus equipment with warranty if required

  • 80% Thermal Efficiency

We design with your functional requirements, business operations, and work environment in mind.

  • Keyera Cynthia Power Generation Plant

    The Cynthia power generation plant will produce power for consumption at the Cynthia facility and supplement the local power grid when facility demand is low.

    The facility design includes:

    • Generator building complete with safety systems, HVAC and maintenance access

    • Siemens SGT400 (12.9 MW) gas turbine generator complete with auxiliaries

    • Outdoor turbine generator auxiliary systems including inlet air, exhaust, and oil cooling system

    • Instrument air and fuel gas conditioning systems

    • Outdoor O/H 25kV fused disconnect and riser pole

    • Outdoor transformers:

    • 12 MVA, 13.8kV – 25kV utility step-up transformer

    • 750 kVA, 13.8kV – 600V station services transformer

    • Electrical room within the GTG building including:
    • 13.kV switchgear
    • 600V MCC
    • UPS systems
    • Balance of Plant control panel
    • 600V-120/208V low voltage systems

    • GTG building electrical and instrumentation wiring systems

    • Tie-in to the Altalink Substation metering to facilitate Power Export Control to the transmission system

    • Tie-in to the Cynthia Gas Plant automation control system (DCS/PLC)

    • Altalink SCADA system installation (scope to be defined)

  • NuVista Wembley Cogeneration Plant

    The exhaust heat from the generator engines will be captured in waste heat recovery units to offload the process heating system. In total, the units will supply approximately 16 MW of continuous power and 10 MW of process heat to the existing glycol heat medium system. The existing step-down transformer and meter will stay in service to ensure stable and continues power to the gas plant.

    The facility design includes:

    • Gas Turbine Generator with Waste Heat Recovery Unit (WHRU) at NuVista’s (NVA) Wembley Gas Plant. The plan is to generate between 13.3 and 17.6 MW of power, depending on the ambient temperature to offset the current grid supplied power and recover the exhaust heat to offset the facility process heat loads which are currently provided by fired heaters.  

    • A new pipe rack approximately 200m long was installed to support the hot oil supply and return lines, and the fuel gas delivery line.

    • The existing glycol heat medium system in area 600 had one of the fired heaters removed and replaced with a heat exchanger that will heat the glycol using the hot oil heat medium.
