How Gilkes can maximise your hydropower potential
Step 1
Hydropower assessments
With a long standing history in hydropower spanning design, manufacture, repair and refurbishment, Gilkes is well placed to support the development and long-term performance of your hydro power plant.
While we frequently upgrade original Gilkes equipment using site records, our expertise extends to systems from other manufacturers. We’ve modernised equipment from as early as the 1900s, including projects in Kenya, New Lanark and the Balmoral estate, as well as more recent installations worldwide.
Whatever the age or condition of your facility, the first step to extending it’s lifespan is a consultation, site survey or condition assessment. This allows us to identify opportunities for improvement and recommend the most appropriate solution.
Step 2
Hydropower parts & refurbishment
Decades of operation can wear down components. Gilkes offers comprehensive refurbishment solutions designed to rejuvenate installations and significantly extend operational lifespan.
- Reconditioning of existing component to restore performance
- Supply of replacement components such as runners, guide vanes, spears and nozzles
- Gilkes investment in 3D scanning technology allows our engineers to reverse engineer hydropower components when the original information is not available
- Minimised downtime by supplying components in parallel with machine running or choosing dry season to take machines offline
- Updated equipment to reflect today’s expectations for safety, durability, and compliance
Modernisation for improved performance
Ageing components, evolving regulations, and advancing technology make upgrades essential. Gilkes offers cost-effective modernisation services to optimise performance for future demands.
- Upgrade old mechanical governors to advanced digital ones for improved precision and to allow remote monitoring
- Automation through use of digital control systems helping to reduce operational costs
- Enhance turbine and generator components to maximise output
- Key updates and upgrades to enhance current operations and reduce maintenance costs
- Engineered for reliable performance under today’s safety and compliance standards
Turbine replanting: the ultimate upgrade
Replanting a turbine can be the chosen option if the original no longer meets requirements or if the site characteristics have changed. A full replanting solution ensures long-term reliability, efficiency, resilience, and compliance.
- Increase capacity and efficiency utilising new enhanced designs
- Meet modern standards with an adherence to higher standards of safety, resilience, and compliance
- Option to replant turbine alongside new M&E equipment
- Future-proof operations by adapting to changing energy needs such as increased demand for power or a change in grid constraints
