According to Bloomberg New Energy Finance (BNEF), renewable energy capacity awarded through auctions reached over 50 gigawatts (GW) in 2017 alone. That is a 51% increase from 2016, and about 4-6 times more than volumes awarded annually from 2013 to 2015.

Auctions provide transparency on costs and foster competition enabling reduction in renewable energy prices. Announced well in advance, they also give developers a clearer sight of opportunities ahead.
Auctions are now a particularly popular policy tool in Asia (especially in India and China), Europe (Germany, France, Spain), Central & South America (Brazil, Mexico), as well as the Middle East & North Africa.
In 2017, auctions delivered impressive results such as onshore wind and solar photovoltaic at around $2 cents per kilowatt-hour in Mexico, or subsidy free offshore wind power in Germany and the Netherlands.
