Flexible power for data centres could save €196 billion, Wärtsilä study finds
Flexible engine-based power systems could save up to €196 billion over 20 years while sharply reducing water and land use as data centre capacity expands, according to a new study by Wärtsilä.
The report, Unlock power. Unleash growth: How data centres can create tomorrow’s power system flexibility, models a scenario in which global off-grid data centre capacity reaches 55 GW by 2035. It finds that using flexible engines instead of combined-cycle gas turbines (CCGTs) could reduce water use by 99.97% and require land equivalent to 2,200 fewer football pitches.
With global data centre capacity projected to nearly triple by 2035, onsite power is gaining traction as developers seek to avoid lengthy grid connection queues. Wärtsilä says flexible engines could also provide backup power and, once facilities connect to the grid, help balance fluctuations in wind and solar generation.
The study argues that investing in flexible generation and energy storage...
