The post Economic Factors Drive Wind and Solar Growth appeared first on POWER Magazine.

Researchers at Lawrence Berkeley National Laboratory (LBNL) have found that a combination of lower capital, operating, and finance costs, in addition to better equipment performance, and longer useful lives, have driven power purchase agreement (PPA) prices and the levelized cost of energy (LCOE) for utility-scale wind and solar projects to all-time lows. The findings were presented by Mark Bolinger, research scientist in the Electricity Markets and Policy Department at LBNL, during a webinar focused on trends in deployment, cost, performance, pricing, and market value for utility-scale wind and solar.

A Decade or More of Phenomenal Growth

Bolinger noted that from 2006 to 2019 wind power capacity operating on the U.S. grid had grown by nearly an order of magnitude—from 11.5 GW to 106 GW. The percentage increase in utility-scale solar photovoltaic (PV) capacity, which researchers define as ground-mounted systems with capacities greater than 5 MW_AC, has been even greater, increasing from 1.7 GW in 2012 to 29 GW at the end of 2019.…
