porting year 2013, to 25 percent in 2023. The average cost per installed capacity for the first set of wind projects, approved in 2010, reached US$2 million per MW, while the wind project approved in 2014 cost around US$1.8 million per MW of installed capacity, highlighting the gradu
This study assumes long lives for transmission assets, discount rates based on the cost of capital for U.S. utilities, and regionally specific capacity factors based on empirical observations. The results show no large, consistent disparity in the capital cost of transmission between utility-scale solar and wind resources.
Proposed projects are more expensive than constructed ones, and bulk transmission costs constitute most of the total transmission costs. Wind interconnection costs are significantly lower in PJM than in MISO, whereas solar costs are higher. Fig. 3. Range of levelized costs for selected utility-scale projects in PJM. 4.1.3. EIA
