  • *A 1,000 Megawatt wind farm would require (approximately):
    • 1 million tons of concrete
    • 200,000 tons of steel
    • 2 million man-hours of labor for foundations
    • Foundation Production Cost: >$200 million

Support for Michigan’s offshore wind energy production is growing…an opportunity for Mason and Oceana counties?

To develop a 1,000 MW offshore wind farm in Lake Michigan


  • Strong political drivers towards offshore
  • Many studies are being performed
  • Few developers active today in Lake Michigan
  • Possibly faster time-to-market vs. onshore due to fewer land lease issues
  • Other than land, more or less the same issues as onshore

      • Job creation
  • EIS screening study:
      • List all studies to be conducted above water
      • List all studies to be conducted below water
      • Permit execution
  • Secure area control, describe the process:
      • Where to apply
      • How to apply
      • All legal contracts and approvals: aviation, defense, ship traffic, etc
  • First draft progress plan
wind quality and load centers in the u s
Wind Quality and LoadCenters in the U.S.

Michigan is situated near three large load centers

  • Blue - high wind potential
  • Brown - large demand centers
  • Green - little wind and smaller demand centers.

michigan great lakes offshore wind council glow suggestions for focus points
Michigan Great Lakes Offshore Wind Council (GLOW) -- Suggestions for focus points
  • Define how much wind power the State wants -- onshore and offshore -- based upon State goals for renewables and emissions reductions
  • Legislation
  • Wind measurements, different procedure
  • Define standard EIS procedures based upon the 22 criteria
  • Set the criteria where possible
  • Create an overview outlining all agencies with wind farm approval impact
  • Create an overview detailing all stakeholders in Michigan, and advise regarding “best practice” information collection and distribution
  • Grid
    • how to influence the grid solutions
    • Financial models
  • Support schemes for offshore wind farms
compensation models
Compensation models

Direct Compensation:

  • Deliver local revenue – an amount that is meaningful to the regional stakeholders via an annual payment; likely a per megawatt-based formula -- a fixed amount to a Community Trust; or a royalty payment based on production (or a combination thereof)
  • A royalty payment to the State of Michigan – a lease payment and/or royalty payment based on production
  • Target an amount that maximizes stakeholder participation while maintaining an attractive rate of return for the project’s institutional investors/owners

Indirect Compensation:

  • Job creation during construction and after commissioned (operations and maintenance)
  • OEM facilities/operations; maintain project size and scope – a large project could attract industry supply-chain, more jobs
  • Regional power plant fleet is aging; replace and support growth in power consumption, while addressing Michigan’s Renewable Portfolio Standard
to do list
To-do list
  • Schedule additional Public Information meetings in Mason and Oceana counties
  • Continue to meet with stakeholders
  • Continue discussions with Consumers Energy and DTE Energy
  • Partner with riparian owner, submit joint lease application to the State
  • Documentation process – studies, permits and approvals
  • Technical engineering
the way forward
The Way Forward
  • Emphasis on Feasibility Study stage in process, no decisions yet
  • Local support is critical, no way forward without it
  • Wind Farm size and shape to be determined by gathering input from all stakeholders as well as engineering considerations
  • “Give and Take” acknowledgement by all stakeholders
