SGRE wins over 500MW of repowering deals

UNITED STATES: Siemens Gamesa Renewable Energy (SGRE) has signed two agreements to repower three NextEra Energy wind farms in Texas, with a combined capacity of more than 500MW.

Repowering turbines at NextEra Energy's King Mountain will improve reliability at the 268MW site, Siemens Gamesa stated

The manufacturer will refurbish 362 units of Vestas’ V47-660kW model at the 82.5MW Indian Mesa and 160MW Woodward wind farms in west Texas.

Vestas’ turbines will be overhauled with a hardware and control upgrade, increasing their output to 710kW from 660kW, and adding ten years to their original design life, Siemens Gamesa stated.

The 7.57% increase in power rating means Indian Mesa will have a capacity of 88.75MW and Woodward will become 171.8MW.

Under a second agreement, the manufacturer will refurbish 210 units of Bonus’ legacy 1.3MW turbine at the 278.2MW King Mountain wind farm in Upton County, which is also in west Texas. The project was completed in 2001. 

Siemens Gamesa will provide "upgraded materials, warranty and commissioning services" for the turbines, enabling more reliable performance, it added.

Siemens acquired turbine manufacturer Bonus in 2004.

Nearly 2GW of repowering took place in the US last year, mostly performed by GE, according to FTI Consulting.
