Why is wind energy investment growing?

A driver behind the growth in wind energy investment is the falling cost of wind-produced electricity. The cost of generating electricity from utility-scale wind systems has dropped by more than 80%. When large-scale wind farms were first set up in the early 1980s, wind energy was costing as much as $0.30 (kW h) −1 (30 cents per kilowatt-hour).

What is the capacity factor of a wind farm?

Of the wind farms surveyed, the highest recorded capacity factor (CF) was 38.48%, the lowest CF was 19.36% and the average CF was 27.9%. This data was extrapolated from a Single Electricity Market Operator (SEMO) source. The success or failure of wind turbine investments ultimately depends upon many factors.

How much does a wind turbine cost?

IC The initial capital investment or Capex is the total cost of the entire installation, which according to AWEA (American Wind Energy Association) is about $1.3 million for a 1-MW (1,000 kW) turbine. AEP For the annual energy production, assume a 39% capacity factor. That is, a turbine will generate on average 39% of its nameplate rating. Hence:

Is wind energy a viable investment?

In this way, wind energy will gain more relevance. As large-scale wind generation projects involve high complexity and capital cost, the economic analysis of these investments becomes fundamental. This study provides state-of-the-art in the literature on the economic feasibility of wind energy generation through a systematic literature review.

How do energy costs affect onshore wind turbine prices?

While energy costs are a small share of total onshore wind turbine prices, reduced energy use per kW and lower energy prices contributed to reduced overall turbine costs. Analysing the results for two periods also reveals the changing nature of industry cost reduction efforts impact on some techno-economic variables.

Can subsidies increase wind energy generation capacity?

Baringo and Conejo optimized wind projects along with grid improvements necessary for project implementation. The authors argue that relatively small subsidies on investment costs can substantially impact projects to increase wind energy generation capacity.
