RES, Vestas talk US project supply

Renewable Energy Systems Americas is negotiating a supply contract for 100 V100 wind turbines with Vestas for its Pleasant Valley wind project in southeastern Minnesota, Recharge learns.

The Minnesota Public Utilities Commission recently approved the developer’s application to amend the site permit from the original 301MW nameplate capacity project to 200MW, which is the amount Xcel Energy’s Northern States Power unit has agreed to purchase under a long-term agreement.

Last September, RES Americas and Vestas announced an umbrella turbine supply agreement for up to 610MW with a firm 60MW order.  It was unclear if Pleasant Valley would be part of that deal.

The PUC decision enables RES Americas to utilize taller 311.7-foot (95-metre) towers and reconfigure the project layout to fit the smaller installed generation capacity.

“As a result, we are contemplating using Vestas turbines for the project. However, negotiations with Vestas have yet to be finalized,” Rob Morgan, chief development officer at RES Americas, tells Recharge. Plans call for bringing the project into service in 2015.

The developer had originally considered using 188 General Electric turbines on 270-foot (82.5-metre) towers or 130 Siemens units on 262.5-foot (80-metre) towers.

PUC spokesman Dan Wolf says that RES Americas now has all the necessary approvals to “continue on with the project and place it into service.”
