HB: this seems more like the resource extraction point, which is connected to a steam pipe, which travels to a generator building with a turbine/head exchanger inside. So not really accurate to use power=generator.
tagging as bore to distinguish it from man_made=water_well.
HB Aug 2012: checked for new dataset. tagging the same as previously uploaded V16 data for the Mainland, but there are about a dozen new ones to merge in so not calling it complete.
