With every new plant we deliver, we also take responsibility for its long-term operation. Technical demands on hydropower plants are increasing, and regulatory requirements are becoming more extensive – this is precisely where sora supports operators with reliable service solutions.

We carry out regular inspections, functional tests, and recurring service tasks to ensure that each plant remains safe, efficient, and trouble-free.

Whether it’s annual service visits or custom inspection intervals, we provide our clients with technical expertise and clear guidance – reliably, professionally, and for the long term.

Even during daily plant operations, we support our clients with targeted maintenance. We replace wear parts, perform bearing changes on generators and turbines, carry out repairs, and assist operators in keeping their plants in optimal operating condition.

Thanks to our in-house production, we can provide spare parts quickly and precisely – often customized or manufactured on short notice.

Whether it’s scheduled maintenance intervals, operational repairs, or technical support during ongoing operations, we ensure that every plant continues to operate stably, efficiently, and reliably.

After many years of operation, hydropower plants reach a point where a comprehensive overhaul becomes advisable. We offer complete or partial revitalizations, bringing existing plants up to the latest technical standards.

We renew worn components such as bushings, seals, and bearings, refurbish or replace generators, update sensors and controls to current standards, and can convert hydraulic drives to electromechanical solutions.

Existing steel components and load-bearing structures are – where sensible – reused and combined with new components. This results in a modernized plant that operates reliably, efficiently, and durably once again.
