High wind speed










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

  • Pro’s

    • Self Generation Incentive Program (SGIP)

      • $1,000 or $1,500 per kW?

      • Size increased to 5 MW? (1 MW eligible)

      • Moved from Level 1 to Level 3-R?

      • Funded $125m in 2005. Program through 2014

    • Net Metering Law (1 MW)

    • High Electric Rates

    • “Progressive” State

  • Con’s

    • Limited Number of Large Loads in Windy Locations

    • Regulatory Environment (No Green Tag Sales!)

    • SGIP Funding for Wind affected by PV Funding

Why does wind power make sense for distributed generation applications l.jpg
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 l.jpg
Implementing Wind Power for Distributed Generation applications?

  • 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 l.jpg
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 l.jpg
In Summary Applications

  • 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 l.jpg
Challenges and Solutions Applications

  • 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.

Challenges and solutions29 l.jpg
Challenges and Solutions Applications

  • 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.
