Hydropower, which harnesses the energy of falling water, has been a cornerstone of renewable energy for more than a century. Today, it meets about 16% of the world’s energy needs and accounts for 71% of all renewable energy. As the hydropower industry evolves, the integration of Industrial Internet of Things (IIoT) technologies provides transformative solutions to optimize performance, increase reliability and propel the industry into the future.
The evolution of hydropower: from turbines to digitalization
Hydropower has witnessed several industrial revolutions:
1. The first industrial revolution (18th-19th centuries):
– Key inventions: Francis and Pelton turbines remain staples in the industry today.
– The world’s first hydroelectric project lights up a single arc lamp in Northumberland, England.
– Rapid expansion of hydroelectric power plants around the world.
2. The Second Industrial Revolution (20th century):
– Steady progress in mechanical systems (gears, levers and pulleys).
– Limited technological change.
3. The Third Industrial Revolution (Digital Revolution, 1980 to present):
– Transition from analog to digital systems.
– Integration of information and communication technologies (ICT) in power plants and power grids.
– The advent of automation and digital speed governor control.
4. The fourth industrial revolution (Industry 4.0):
– Build on digital advancements.
– Industrial IoT and cyber-physical systems transform industrial processes.
Next steps: IIoT and Industry 4.0
