Wind turbine energy optimization
Wind Turbine - Energy Optimization

  • Expected to produce ~ 3,810 MWh annually based on 29% capacity factor (P50); ~ 3377 MWh annually based on 25.7% (P50)

  • Annual load from treatment systems in 2007 ~ 12,300 MWh; in 2011 ~10,862 MWh

  • Expected to generate 25-30% of AFCEE’s total electrical requirement (>$2M in 2009; $1.7 M in 2011)

  • Expected to reduce ~25-30% air emissions

  • Payback originally anticipated in 6-8 years (RECs/O&M); working on a better ROI/SROI



Wind turbine costs
Wind Turbine Costs

Notable issues lessons learned
Notable Issues/Lessons Learned

  • Communicate early and often with stakeholders

  • Understand net-metering, RECs, and state rules

  • Utility Interconnection – build in time and plan for costs

  • Logistics - room to haul and build (bridges, road width, corners, permits, bad drivers, Military Cargo Preference Act of 1904, etc)

  • Explore additional grants

  • Inspect the manufacturing facilities if possible

  • Make sure the turbine components suppliers and transportation companies are insured.

  • Evaluate modes of transportation (roadway, rail, barge)


Notable issues lessons learned1
Notable Issues/Lessons Learned

  • Construct foundation in cool weather and allow time to achieve strength

  • Long lead time on turbines - explore interest from manufacturers

  • Plan on a schedule and hold contractors to it – include liquidated damages in contracts

  • Plan submittals (deliverables) and have a submittal register

  • Use existing wind resource data and other studies if available and applicable

  • Evaluate warranties and O&M/service contracts in advance; build in availability guarantee

  • Consult experts (i.e. DOE) on funding mechanisms (EULs, ESPCs, tax credits)

  • Don’t plan a ribbon cutting ceremony until the turbine is up and operational

  • Long Haul Project – need a dedicated champion

  • Take photos and video


  • Do spare parts come with the wind turbine purchase?

  • Just because spare parts are new doesn’t necessarily mean they will work

  • Plan for technical and safety training – involve local emergency response personnel

  • An FAA ruling of presumed hazard is not the end of a project, it’s the beginning of negotiations

  • Ensure manufacturers are reputable and there are working wind turbine models in the US for several years

  • Select contractors who have experience with wind turbine planning and construction projects

  • Are anchor bolts sized correctly? Metric vs english conversions can cause problems

  • Provide site signage/directions to transportation companies and police details
