Functions#

onshore_turbine_capex(capacity, hub_height, rotor_diam)

A cost and scaling model (CSM) to calculate the total cost of a 3-bladed, direct drive onshore wind turbine according to Fingersh et al. [1] and Maples et al. [2].

onshore_tcc(cp, hh, rd[, gdp_escalator, ...])

A function to determine the turbine capital cost (TCC) of a 3 blade standard onshore wind turbine based capacity, hub height and rotor diameter values according to the cost model by Fingersh et al. [1].

onshore_bos(cp, hh, rd)

A function to determine the balance of the system cost (BOS) of an onshore turbine based on the capacity, hub height and rotor diameter values according to Fingersh et al. [1].

reskit.wind.economic.onshore_cost_model.onshore_turbine_capex(capacity, hub_height, rotor_diam, base_capex=None, base_capacity=None, base_hub_height=None, base_rotor_diam=None, tcc_share=None, bos_share=None)#

A cost and scaling model (CSM) to calculate the total cost of a 3-bladed, direct drive onshore wind turbine according to Fingersh et al. [1] and Maples et al. [2]. A CSM normalization is done such that a chosen baseline turbine, with a capacity of 4200 kW, hub height of 120 m, and rotor diameter of 136 m, corresponds to a expected typical specific cost of 1100 Eur/kW in a 2050 European context according to Ryberg et al. [4] The turbine cost includes the turbine capital cost (TCC) and balance of system costs (BOS), amounting to 67.3% and 22.9% respectively [3], as well as finantial costs equivalent to the the complementary percentage.

Parameters:

  • capacity (numeric or array-like) – Turbine’s nominal capacity in kW.

  • hub_height (numeric or array-like) – Turbine’s hub height in m.

  • rotor_diam (numeric or array-like) – Turbine’s hub height in m.

  • base_capex (numeric, optional) – The baseline turbine’s capital costs in €, by default 1100*4200 [€/kW * kW]

  • base_capacity (int, optional) – The baseline turbine’s capacity in kW, by default 4200

  • base_hub_height (int, optional) – The baseline turbine’s hub height in m, by default 120

  • base_rotor_diam (int, optional) – The baseline turbine’s rotor diameter in m, by default 136

  • tcc_share (float, optional) – The baseline turbine’s turbine capital cost (TCC) percentage contribution in the total cost, by default 0.673

  • bos_share (float, optional) – The baseline turbine’s balance of system costs (BOS) percentage contribution in the total cost, by default 0.229

Returns:

Onshore turbine total cost

Return type:

numeric or array-like

Notes

The expected turbine cost shares by Stehly et al. [3] are claimed to be derived from real cost data and valid until 10 MW capacity.
