Harnessing the force of nature

Hydropower

Hydropower isn’t just about electricity, it’s about flexibility. It stabilizes grids. It supports wind and solar. It even enables green hydrogen production. As the world searches for efficient routes to reach net zero, hydropower is the wildcard.

Aker Solutions is modernising hydropower to unlock flexibility and extend asset life. Our mission? To help utilities and developers get the most energy from every drop of water.

Hydropower components to ensure safe, reliable operation across the entire plant:

Main inlet valves (butterfly and spherical)
Inlet pipes and pressure shafts
Mechanical equipment for balance of plant

Reversible pump turbines for increased flexibility

Modern energy systems need flexibility. Wind and solar are clean, but they’re unpredictable. When the sun shines and the wind blows, power surges. When they don’t, the grid needs backup. Reversible pump turbines turn hydropower plants into giant batteries – providing energy storage at scale, grid stability and cost efficiency.

Upgrading existing plants with reversible pump turbines unlocks new flexibility without constructing new dams.

Aker Solutions’ reversible pump turbine technology is continuously improved to maximize efficiency, stability and output across a wide range of operating conditions. Our patented advanced regulation system enables both fixed‑speed and variable‑speed operation, improving response times, operational flexibility and performance.

Capacity & precision technology at Tranby

Our 4,000 m² full‑service hydropower workshop at the Tranby Technology Center in Norway provides houses Northern Europe’s largest vertical mill‑turn machine for hydropower components. This capability reduces lead time and ensures the precision needed to improve turbine performance.

Designed specifically for large hydropower components such as turbine runners and covers, the machine offers a turning diameter of 12 meters, a table diameter of 6 meters and a maximum table capacity of 120 tons. Its advanced five‑axis angle head allows precision milling, boring and threading—enabling accurate and efficient refurbishment of even the largest components required for stable renewable energy production.

At Tranby, we machine and refurbish turbine runners, valves and other large components with the precision and speed demanded by modern hydropower facilities.
