THE old hydroelectric power station on the River Dee in Chester has been identified as the ideal site for a new state-of-the-art. "thriving visitor attraction" to celebrate the history of decarbonised energy. Chester generated its own clean carbon-free electricity for almost half of the city's needs from the hydroelectric building on Castle Drive between 1914 and 1949. Next to the Old Dee Bridge and opposite the University of Chester’s Riverside site, the building is currently unused and redundant. The proposal is to turn it into a 'Hydro Hub' acting as a focal point for residents, schools and visitors to learn about what a low carbon world will look like and how all aspects of our lives will change as new technologies remove emissions from our industry, commerce, agriculture, homes, transport and food.
