Siemens Gamesa to repower 572 Texas turbines for NextEra

Siemens Gamesa Renewable Energy SA (BME:SGRE) will repower 572 wind turbines in Texas under two separate agreements with a unit of NextEra Energy Resources.

As part of one of the two deals, the company will deliver hardware and control upgrades for 362 pieces of Vestas' V47 wind turbines at the Indian Mesa and Woodward wind power plants, it announced today. Thus, the output of each unit will be increased from 660 kW to 710 kW and their life will be extended for 10 years.

Completion of the V47 upgrades is targeted by the end of the year. Siemens Gamesa noted that the wind farms are to remain operational during the works.

The other agreement with NextEra involves the repowering of 210 units of legacy Bonus 1.3-MW turbines by Siemens at the King Mountain park. These have been built in 2001. Siemens Gamesa will provide upgraded materials, warranty and commissioning services, again extending the lifespan of the devices.

SGRE offers solutions in all phases of a repowering project, it said. The upgrades enhance the reliability and reduce the maintenance requirements for the wind farms.

Both contracts with NextEra have been signed in the first quarter of 2018.
