[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. :param capacity: Turbine's nominal capacity in kW. :type capacity: numeric or array-like :param hub_height: Turbine's hub height in m. :type hub_height: numeric or array-like :param rotor_diam: Turbine's hub height in m. :type rotor_diam: numeric or array-like :param base_capex: The baseline turbine's capital costs in €, by default 1100*4200 [€/kW * kW] :type base_capex: numeric, optional :param base_capacity: The baseline turbine's capacity in kW, by default 4200 :type base_capacity: int, optional :param base_hub_height: The baseline turbine's hub height in m, by default 120 :type base_hub_height: int, optional :param base_rotor_diam: The baseline turbine's rotor diameter in m, by default 136 :type base_rotor_diam: int, optional :param tcc_share: The baseline turbine's turbine capital cost (TCC) percentage contribution in the total cost, by default 0.673 :type tcc_share: float, optional :param bos_share: The baseline turbine's balance of system costs (BOS) percentage contribution in the total cost, by default 0.229 :type bos_share: float, optional :returns: Onshore turbine total cost :rtype: numeric or array-like .. rubric:: 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. Sources ------- [1] Fingersh, L., Hand, M., & Laxson, A. (2006). Wind Turbine Design Cost and Scaling Model.
