Wind Energy Costs Wind Energy costs are dependent on yearly wind, installation and maintenace costs Small wind turbines from China cost complete with towers $800/kw (plus delivery min. container load plus 25% installation)and come complete with towers. They range from 1Kw to 20Kw, and come in an array of different configurations. Prices >> Usually a container costs $5500 for both 20' and 40' to Kabul. Please send enquires through contact page If you require wind speed performance data (Power Curves) for these turbines pdf (0.23mb) >>>>> For small wind turbines here is a graph on costs production efficiencies: A simple example is: $1,560,000 / MW or $1560 / kW 1.50 MW / Turbine Cost of each Turbine = $2.33m Cost of electricity at 40% efficiency is 0.4 x 1.5 x 1000000 = 0.6MWh x 365 day x 24h= 5.256 GWh/year over 10 years = 52.5GWh or 0.000297 cents/kWh. For a 20MW plant or 12 Turbines will cost 2.33 x 12 (27 MW installed)= $27.96m at 25% efficiency this plant will produce 7MW. enough for the pipeline. at 5 cent/kWh this equates to $0.05 x 24h x (0.7 factor) x 365 days x 7,000 kW/h = $2.146m this plant will break even in $27.96m / $2.146m/yr = 13yrs at 25% eff at 50% eff and 10 cents /kWh break even is = $27.96m / $8.6 m/yr = 3.25 yrs Naeem |
