Motivation for Low Wind Speed Technology R&D

  • Current Situation
    • Wind viable at higherwind speed sites(Class 6 – avg. 15 mph @ 10m)
    • Limited high wind sites
  • Subsidies important
  • New Focus Needed
    • Shift to future industry needs
    • Broaden range of competitive opportunities
    • Eliminate the need for subsidies

why does wind power make sense for distributed generation applications
Why does Wind Power make sense for Distributed Generation applications?
  • Technology improvements have dramatically lowered costs and increased reliability
  • US State and Federal incentive programs are making wind projects economically attractive
  • Much more economical than other renewable technologies in most places
  • Increasingly positive public perception is making siting and permitting easier

Debenham Energy LLC

implementing wind power for distributed generation
Implementing Wind Power for Distributed Generation
  • Suitable Sites
    • Good Wind Resource
    • High Utility Power Cost
    • State Incentive Program
    • Permitable (allowed with zoning variance)
    • Connectable (Utility Interconnection Agreement)
  • Mid-Size Wind Turbine Availability
    • Mid-Sized wind turbine production in decline
    • Manufacturers are too busy with large projects

Debenham Energy LLC

mid sized wind turbines for distributed generation applications
Mid-Sized Wind Turbines for Distributed Generation Applications
  • Located at facility “after the meter” where retail power can be displaced
  • Reduces facility monthly utility energy bill
  • Sells excess power back to utility during off-shift and/or during windy periods.
  • May provide additional benefits: Visual evidence that the facility generates and uses green power

in summary
In Summary
  • Mid-Sized wind turbines can be economical in distributed generation applications given the right combination of factors:
    • Windy Location
    • State and / or Federal Economic Incentives
    • High Power Cost
    • Good Load Match with the Host Site (Net Meter)
  • Other benefits may be available as well
    • Green Image
    • Green Tags (REC’s/TRC’s)

challenges and solutions
Challenges and Solutions
  • Challenge:
    • Accurately Assessing the Wind Resource.
  • Solution:
    • Assessment Confirmed Independently by a Private Meteorologist and NREL. Installed 2 MET’s to Determine Optimal Location.
  • Challenge:
    • Risk Responsibility – Wind Resource, Turbine Performance/Availability
  • Solution:
    • Agreed on TMY for Wind Energy.
    • Used Independently Verified Performance Data Less Expected Degradation.
    • Availability Independently Estimated. Response Times Written Into Maintenance Subcontract.

Debenham Energy LLC

challenges and solutions29
Challenges and Solutions
  • Challenge:
    • Operational Costs for a Single Turbine
  • Solution:
    • Scope of Operations Responsibilities Shared Between Developer and Owner
  • Challenge:
    • Funding Long Term O&M
  • Solution:
    • Sinking Fund in Place for ‘Expected” Maintenance and Repair Costs in Order to Assure that Availability is as Predicted.
  • Challenge:
    • Tax and Environmental Benefits are Substantial but Hard to Incorporate
  • Solution:
    • Production Tax Credits, Accelerated Depreciation and REC’s (Green Tags) were not Included.
