Title: III.a.1 Onshore Wind Costs

Content: This covers large onshore wind turbines - Please click on: onshore wind cost data

Small onshore wind turbines are costed as part of IV.c Small-scale wind Costs.

Offshore wind turbines are costed as part of III.a.2 Offshore wind Costs

h1 Costs Methodology

h2 Methodology used

The user defines the number of onshore wind turbines. Once the trajectory is set by the user, the number of plants to be built are defined. Investment costs are a function of new build and operating cost are a function of the number of plants operating within that time period. We assume turbines retire after 20 years and the cost of replacement is included.

Please see 2050 Methodology for a full description of the costs approach in the Calculator.

h2 Methodology issues and uncertainties

* The capacity factor appears quite ambitious in comparison to other models

* £/MWh figures appear high, especially when compared to other studies

h1 Technical Assumptions

* Lifetime =  20yrs
* Efficiency =  Capacity factor = 30% 
* Input Fuel = Wind
