Modeling has also shown that it's relatively inexpensive to increase the reliability of the total wind output to a level equivalent to a coal - fired power station by adding a few low - cost peak - load gas turbines that are opearated infrequently, to fill in the gaps when the wind farm production is low (Diesendorf 2010).

«Our findings show that China's underperformance is also driven by suboptimal turbine model selection (31 % of the gap), wind farm siting (23 % of the gap), and turbine hub heights (6 % of the gap)-- factors that have received less attention in the literature and, crucially, are locked - in for the lifetime of wind farms,» explain the authors, who were supported by Harvard University, US, and are now at the University of Minnesota, US, Florida State University, US, and Cambridge University, UK.
