Vestas will supply 132 of its V90 3MW machines for the developer’s project in the Tehuantepec Isthmus region of Mexico’s Oaxaca state, with delivery to begin in the second quarter of 2012.

The contract includes a 10-year service and maintenance agreement. Mareña Renovables comprises Macquarie Mexican Infrastructure Fund, Mitsubishi Corporation and PGGM, a Dutch pension fund.

Vestas says the sale takes its firm orders for 2012 to 865MW.

Japanese conglomerate Mitsubishi announced last month that it is buying a 34% stake in the $1bn project, and said Vestas had been lined up to supply what it claims will be Latin America’s largest wind farm development.

The Danish manufacturer confirmed as long ago as March 2011 that it has held discussions with the Mareña consortium, but until now has said no firm agreement had been signed.

Mitsubishi says the plant will cover “several tens of kilometres” on the Isthmus of Tehuantepec and will use Vestas turbines “designed for offshore wind projects”. It adds that “a strong wind from Gulf of Mexico runs through the region on its way out to the Pacific at a speed of 8.5m per second, which is equivalent to offshore winds”.

The wind farm is expected to be complete by July 2013. It is also being backed by funds from the Inter-American Development Bank (IDB).

Output from the project will be sold to beverage producers Femsa and Heineken under 20-year power purchase agreements.

Mitsubishi says it wants to expand its presence in the renewable energy sector and “expects to see more business opportunities arise” in Mexico, where the government wants to add 20GW of renewable capacity by 2025.
