Hydropower for data centres
Hydroelectric generation can contribute to data-centre electricity supply. A viable project must assess seasonal output, grid access, contracts, resilience and competing water needs.

HYDROELECTRIC ENERGYDATA CENTRES & AIWATER-EFFICIENT COOLINGHEAT RECOVERY
01 / THE OPPORTUNITY
A growing digital economy.
A physical infrastructure challenge.
Computing needs dependable electricity and effective heat management. Hydropower.Global explores where renewable power, responsible water use and commercially viable infrastructure can work together.
Water-efficient cooling
Closed-loop liquid cooling, dry cooling and suitable alternative water sources can reduce pressure on fresh-water supplies. The right approach depends on climate, equipment and the complete cooling system.
Value beyond the server room
Heat recovery and thoughtful site selection can create wider benefits. Opportunities need local heat demand, suitable infrastructure and careful environmental assessment.
02 / UNDERSTANDING THE CONNECTION
Power generation and cooling.
Connected, but different.
Hydropower generates electricity.
Moving water drives turbines to produce power. That electricity can supply computing equipment, pumps and cooling systems. Hydropower does not automatically reduce a data centre’s cooling-water consumption.
Cooling removes heat.
Liquid coolant carries heat away from equipment. A closed loop can reuse coolant, but overall water consumption also depends on how the facility releases that heat. Some systems still use evaporative cooling towers.
Responsible evaluation includes water withdrawals and consumption, reservoir evaporation, drought exposure, river ecology and thermal discharge. Renewable electricity alone does not establish a project’s full environmental performance.
03 / IDEAS ALREADY IN PRACTICE
Real examples. Useful lessons.

Google’s Hamina data centre
Google describes seawater cooling and offsite heat recovery at Hamina. It shows how location and existing infrastructure can shape cooling choices; seawater cooling is distinct from hydroelectric generation.

Microsoft’s new cooling approach
Microsoft’s December 2024 design announcement describes closed-loop, chip-level cooling without water evaporation. It also recognises the electricity trade-off when replacing evaporative cooling.

05 / COMMON QUESTIONS
Hydropower, AI and water use.
Can hydropower reduce the water used to cool AI data centres?
It can supply electricity for efficient cooling, but the cooling design determines direct water consumption. Hydropower’s own water impacts also need assessment. Each project requires a whole-system comparison.
Does liquid cooling always consume large amounts of water?
No. Coolant can circulate within a closed loop. Water consumption can still occur elsewhere, especially where cooling towers evaporate water to release heat. The terms “liquid cooled” and “water efficient” are not interchangeable.
Could a data centre be located near a hydroelectric facility?
Potentially. Proximity alone is insufficient: power delivery, fibre connectivity, flood risk, planning, seasonal water availability, ecology and commercial agreements all matter.
What is Hydropower.Global looking for?
Technical contributors, credible case studies and potential commercial partners who can help develop an informed platform connecting hydropower and digital infrastructure.
