PART 1: HOW AUCTIONS HELPED SOLAR BECOME THE CHEAPEST ELECTRICITY IN THE WORLD
This article is the first installment in a two-part series. The global energy transition has reached an inflection point. In numerous markets, the declining cost of solar photovoltaics (PV) has already beaten the cost of new-build coal and natural gas and is now chasing down operating costs of existing thermal power plants, forcing a growing crowd of thermal generation assets into early retirement. Perfect comparability between dispatchable and non-dispatchable resources invites debate, but the cost declines in solar PV are irrefutable: the global average unit cost of competitively-procured solar electricity declined by 83 percent from 2010 to 2018.
