Project Detail

Pisgah Mountain Wind Energy

Clifton, ME

Scope of Work

Cianbro was the EPC contractor for the Pisgah Mountain Wind Energy project. The engineering, procurement, and construction scope of work consisted of the site development, including access roads and turbine sites, coordination of the transportation of the turbines from the port to the site, erection of five 1.8 MW Vestas V90 wind turbines, underground collection, overhead collection, and a complete collection substation.

Project Details

  • Constructed 3 miles of access roads, 1 mile of crane roads, and 5 WTG pad sites
  • Constructed 5 gravity foundations at 450 cubic yards each
  • Erected five, 1.8 MW Vestas V90 wind turbines, at a 95M hub height, including down tower electrical
  • Installed approximately 6500 linear feet of underground collection
  • Installed approximately 1700 linear feet of overhead line construction
  • Performed site development for substation and all below-grade electrical (grounding and conduit)
  • Erected associated substation steel structures
  • Installed substation bus and tap
  • Procured, delivered, dress filled, and tested main transformer
  • Installed prefabricated control building
  • Installed and terminated all yard P&C cable
  • Tested, commissioned, and turned over a complete operational facility

Lean, Innovative, and Unique Project Solutions

Cianbro engaged and supported the developer 5 years before the engineering and construction phase of the project. Delayed completion of the development cycle put the critical completion milestone in jeopardy. Due to Cianbro’s early engagement, we were able to expedite the critical path electrical engineering and long lead electrical component procurement. This ensured that the project would meet the interconnect dates and the desired COD. Simultaneously, our site design team worked with the owner’s permitting engineer to meet the restrictive permit requirements.
