Hydroelectric power is coming to England's historic Chatsworth Estate, following approval by the Peak District National Park Authority earlier this month.
The plan calls for a pair of Archimedes screw turbines to be installed next to weirs on the eastern bank of the River Derwent. The 3.2-meter-diameter screws will have a combined output capacity of up to 90 kW, accounting for about a quarter of the estate's energy needs.
The planning committee spent significant time trying to minimize the project's visual impact and worked with experts from Historic England, Natural England and the National Park Authority to ensure the two Archimedes screws wouldn't detract from their setting.
"We are happy that the level of visual impact this small scale hydroelectric scheme will have in the landscape is acceptable," Peak District National Park planning committee chair Paul Ancell said. "The Chatsworth parkland contains features from different periods and it is fitting that this 21st Century development will ensure the estate is sustainable into the future."
Chatsworth is the latest in a number of European estates that have elected to add small hydropower projects to their properties
HydroWorld.com reported in January that Scotland's Blair Castle had completed renovations of a century-old generator in January. Meanwhile, England's Cragside Estate announced the installation of a new Archimedes screw turbine this past July, with Blenheim Palace and Windsor Castle having completed hydro projects in 2013.
