Under the terms of the contract, the company will supply 50, V100-2.0MW turbines, which are suitable for low wind sites, to the Yanchi wind farm.

The scope of the contracts also includes providing a VestasOnline Business SCADA solution and a standard two-year service agreement.

Vestas expects to deliver the first wind turbine to the customer under the latest orders in the second quarter of 2014.

The latest orders brought Hanas’ portfolio of Vestas turbines to 350MW from the current 250MW. Hanas plans to add 1GW wind capacity in the windy autonomous region of Ningxia by 2015.

Vestas Asia Pacific & China president Jens Tommerup said that the company has partnered with a customer like Hanas, who have similar priorities as they do.

"With high demands for performance and with the aspiration of building a strong and healthy business, Hanas’ priorities resemble those of Vestas for the Chinese market, where we are seeking to build partnerships that contribute to a healthy business for Vestas," added Tommerup.
