Estimate Turbine Capital Cost¶

• RESKit can suggest a turbine capital cost based on turbie and site characteristics
  • Cost values are intended for a far future context (~2050)
• For onshore turbines: Capacity, hub height, and rotor diameter are considered
• For offshore turbines: Capacity, hub height, rotor diameter, distance from shore, sea depth, and foundation are considered

Workflow:

1. Import required packages
2. Get CAPEX for onshore wind turbine for one location
3. Get CAPEX for onshore wind turbine for multiple locations
4. Get CAPEX for offshore wind turbine for one location
