In March, Mexico’s state utility, Comisión Federal de Electricidad (CFE), departed from almost 80 years of state-owned monopoly and let private companies bid to supply solar, wind, hydro, cogeneration, combined-cycle gas, and geothermal energy.
“The cost was about 4¢ a kilowatt-hour without the mandates, in both solar and wind,” Chu said Friday at Stanford University, where he now teaches. “Four to four-and-a-half cents with no production tax credit, no investment tax credit, no renewable portfolio standard. It’s just money, including profit. This is pretty good news.”
A GTM Research analyst revised the average price slightly higher, to about 5¢/kWh, but that price, too, is much lower than most experts would have predicted renewables would be in 2016.
