Enel Green Power's subsidiary Enel Green Power North America (EGPNA) has commenced construction on the 400MW Cimarron Bend wind farm in the US.

Located in Clark County, Kansas, the project is claimed to be Enel’s largest wind farm.

Owned by EGPNA’s subsidiary Cimarron Bend Wind Project, the wind farm is expected to cost around $610m and is planned to be commissioned in 2017.

Enel global renewable energies division head Francesco Venturini said: "This project marks a major milestone for Enel, as not only will Cimarron Bend be the largest asset in our portfolio, but it also opens our renewable energy to new partners and uses.

"As we continue to invest and grow in the US we aim to cooperate with companies and partners that share the same vision for a more sustainable future."

Nearly 1.8 terawatt-hour of clean electricity generated from the wind farm annually will be sold to Google and the Kansas City Board of Public Utilities (BPU), under two separate long-term power purchase agreements.

The project will generate clean electricity enough to power more than 149,000 households annually, while avoiding around 1.3 million tons of CO2 emissions.

The Cimarron Bend is the first of Enel’s North American wind farms to sell a portion of the power produced to a corporate off-taker.

Earlier this year, Enel said it has started construction of 108MW Drift Sand wind project in Oklahoma.

EGPNA, at present, has more than 2.5GW total installed capacity in US and Canada. This includes more than 2GW of wind capacity, 316MW hydro, 72MW geothermal and 29MW solar.
