The 28.8MW Arriaga development, located in the town of the same name, near the Pacific coastline, comprises 16, V90-1.8MW turbines. Chiapas is the most southern state in Mexico.
The developers, local investment groups Grupo Salinas and Grupo Dragón, handed Vestas the turnkey contract last year.
Chiapas State authorised the project under Mexico's self-supply regulation, whereby the developer buys the power produced unsubsidised. That model is profitable as local winds are often double the typical yields at European sites.
Mexico has around 1300MW of online wind capacity, over half in the self-supply category. It is a trend that will continue as cumulative capacity nears 5GW in 2017 according to data from state utility CFE.
The Global Wind Energy Council estimates Mexican wind capacity could reach 12GW by 2020.
