The impact of wind power support schemes on technology choices

“…C p is the mechanical efficiency. According to Betz' law, it cannot possibly exceed about 59 percent (Narbel et al, 2014). In modern turbines, factors of up 45-52 percent can be observed, e.g.…”

“…In the model, they can choose without constraint from any power density, measured in m 2 /kW . Based on Narbel et al (2014), the general formula for the potentially generated electricity P P ot is spelled out in equation 19.…”

Effective Use of Investments in the Development of the Electric Power Industry

“…These are investments in the wind generator tubes and solar panels as their residual value is close to zero until the energy is generated. [1] It is important to make investment decisions for the Enegetika network. Accordingly, according to economists, the possibility of financial loss due to investment cycles increases the uncertainty of the future value of energy projects.…”

Techno-economic assessments of advanced Combined Cycle Gas Turbine (CCGT) technology for the new electricity market in the United Arab Emirates

“…The economic parameters that influence the LCOE are discount rate, capital costs, fuel costs, and O&M Costs (fixed and variable). Narbel, et al, (2014) detail that for a LCOE calculation for a CCGT, the overall costs can typically be made up of capital costs (14 -31%); fuel costs (61 -80%) and O&M costs (2 -11%).…”
