Under the contract, Vestas will supply 25 V100-2MW turbines for a project in Ningxia province, northwest China.
The contract scope also includes a Vestas Online Scada system and a two-year AOM4000 service agreement.
The wind turbines are scheduled to be delivered in March 2015 and will complete installation in the second quarter of the year.
Vestas Asia Pacific and China president Chris Beaufait said: "We celebrate yet another order from long-time Vestas partner Hanas – the fourth order they have placed with us this year.
"We have been working closely with Hanas for several years to provide them with products and solutions to match their on-site wind conditions and maximize their energy output."
Hanas president Ma Fuqiang said: "We have a strong commitment to wind energy, and we are looking for a long-term trusted partner who can help us achieve a good return on investment. That is why we have been partnering with Vestas for the past five years, and we are glad to continue our great collaboration."
