The company will refurbish the generators at the Mattmark and Mauvoisin hydroelectric power plants located in the canton of Wallis,bordering France and Italy.

The plants have a combined generating capacity of 680MW of electricity and meet 15% of the canton’s electricity needs.

ABB Power Systems division Power Generation business head Franz-Josef Mengede said the upgrade and refurbishment of the hydropower plants will help increase availability of power supplies and enhance efficiency and reliability.

"This project is another example of our increased focus on service as a strategic growth driver and leveraging of renewables and energy efficiency as key contributors in minimizing environmental impact," Mengede said.

ABB is also executing a $120m order to provide turnkey electrical, automation and control solutions for the Linth-Limmern pumped-storage hydropower station being deployed in an underground cavern in the Linthal valley, located in the canton of Glarus.
