Italian multinational renewable energy company Enel Green Power (EGP) has begun construction works for expanding Cimarron Bend wind farm in Clark County, Kansas.

As part of the expansion, EGP will install 74 new wind turbines to increase the project’s capacity from 400MW to 599MW.

In a statement, the company said the wind farm expansion work will cost $281m.

Enel Green Power CEO Antonio Cammisecra said: “As one of the largest renewable power producers in North America, Enel Green Power is committed to excellence in not only developing and constructing new projects but also strategically expanding our existing fleet.

“The expansion of Cimarron Bend is a testament to both the maturity of our wind operations and our commitment to growing a portfolio of state-of-the-art renewable plants that will generate value for many years to come while providing sustainable energy.”

The company expects expansion work to finish before the end of 2020. This will make Cimarron Bend the largest wind farm in Enel’s North American portfolio.

With the additional capacity, the wind farm will generate more than 2.7TWh of clean energy annually and will offset 1.8 million tons of carbon emissions per year.

Under a 15-year power purchase agreement (PPA), a 150MW portion of the expansion will be supplied to electric services company Evergy.

The PPA will also support Evergy’s Renewables Direct programme, allowing customers to offset some of their energy usage through renewable sources.

Evergy products and solutions, renewable sources manager Kevin Brannan said: “As we continue implementing more renewable energy into our overall generation mix, Evergy is pleased to partner with Enel on this expansion project to add to our total wind capacity.

“This helps us reduce carbon emissions and increases our wind energy levels, which leads us toward more sustainable operations and ultimately benefits our customers.”

Missouri Public Utility Alliance (MPUA) joint action agency, the Missouri Joint Municipal Electric Utility Commission (MJMEUC) has agreed to purchase 30MW portion of the project under a 12-year bundled PPA.

Last November, Enel Green Power North America started construction works of the 299MW Aurora wind farm in the state of North Dakota, US.
