Wind Farm Design Considerations
•Apply for electrical interconnection.
•Conduct interconnection studies.
•Payments to transmission operator.
•Establish contiguous block of wind
leases.
•Evaluate community attitudes toward
wind farm.
•Open communication with community leaders
and government officials.
•Hold informational meetings during design, construction
and operations.
Conduct desktop level environmental and cultural resource studies early on.
Preliminary risk assessments.
Multi-year avian and bat surveys.
Sensitive habitat assessments.
Cultural resources studies.
Noise and flicker modeling.
Final risk assessments.
Use results to drive design.
•Multi-year measuring campaign (MET Towers).
•Wind Resource Evaluation and Mapping.
•Use results to inform turbine siting.
Strong Wind Resource
Low Impact
Transmission / Interconnection
Community Support /
