SADDLE BRIDGE HYDRO-ELECTRIC STATION

Steve Grigg

In 1905 this hydroelectric plant was built at Saddle Bridge beside the O Brook on the Hexworthy road to supply electricity to Hooten Wheals (Hexworthy) Mine. The station had its water supplied by a 16 inch iron pipe to a Pelton Wheel, which took its supply off the Wheal Emma Leat at a point on the hillside above.

The electricity generated supplied the Power House beside Low’s Shaft for the mine and New Mill for the stamps, jigging tables and buddles. It is said that an armature of a dynamo can still be seen in one of the buddles.

Old iron pipe found below Saddle Bridge at SX66231 72345. Was this part of the original pipeline (now moved) – It certainly looks like the correct diameter.
