Meridian Way Wind Farm

Meridian Way Wind Farm

Location: Cloud County, Kan.

Client: Horizon Wind Energy

Completion Date: Commercial operation: Nov. 30, 2008

Burns & McDonnell performed engineering design on the collection system, substation and transmission of Meridian Way Wind Farm in Cloud County, Kan. This project connected the largest wind farm in Kansas to the South Power Pool system using the largest in-land wind turbine (3 MW).

  • 34.5-kV collection system design for two 100-megawatt (MW) wind farms
  • Design for two collector substations (34.5-kV/230-kV)
  • Design for two 230-kV transmission lines
  • Major equipment and construction specifications
  • Wetland delineations/permitting

This wind farm project consisted of two separate 100-MW wind farms with a total of 67 wind turbine generators (WTG). Each wind farm had its own collector substation that gathered the power from the individual WTGs via four 34.5-kV feeders. At each collector substation, the 34.5-kV power from the wind farm was stepped up to a transmission voltage of 230 kV. Power from the collector substation west was transmitted to collector substation east through an overhead transmission line (approximately 11 miles). From collector substation east, power was sent through an overhead transmission line (approximately 5 miles) to an interconnection substation where it was connected to the rest of the Cloud County power system. Plans call for an additional 200 MW of wind power in this area.

Burns & McDonnell was responsible for wetland delineation/permitting (Section 404 and 401) and provided environmental support where necessary for the transmission and collection systems.

34.5-kV Collection System

Burns & McDonnell was responsible for designing, specifying and supporting construction for two wind farms, each consisting of approximately 100 MW. There were four 34.5-kV underground collection feeders identified for each wind farm.

230-kV Transmission Line

Burns & McDonnell was responsible for designing, specifying and supporting two sections (5 and 11 miles) of 230-kV single circuit transmission lines.

34.5-kV/230-kV Collection Substation East (approximately 100 MW each)

Burns & McDonnell was responsible for designing, specifying and supporting construction for a 230-kV radial bus substation with major equipment consisting of three 230-kV breakers, one 34.5-kV/230-kV, 115 MVA step-up transformer, one 35-kV switchgear lineup, 20 MVAR switched capacitor bank and 4 MVAR Dynamic Var Compensator.

34.5-kV/ 230-kV Collection Substation West (approximately 100 MW each)

Burns & McDonnell was responsible for designing, specifying and supporting construction for a 230-kV radial bus substation with major equipment consisting of one 230-kV breaker, one 34.5/230-kV, 115 MVA step-up transformer, one 35-kV switchgear line-up, 15 MVAR switched capacitor bank and 4 MVAR Dynamic Var Compensator.

The aggressive project schedule, dynamic changes during permitting and design, and limited information available for a detailed design made this a challenging and exciting project.
