Well I now know what a Power Flume is. Were there any instances in Britain where hydroelectric schemes were used used to supply power to the mines?

EDIT.
It was an integral part of the Tacoma Hydroelectric Project in southwest Colorado. The project was undertaken in order to produce cheap power for the mining operations at Silverton. Due to leakage, the original wood flume had to be replaced in 1927-28, by a semi-circular one made of treated Oregon fir. Both flumes were used to transport water from Electra Lake to Forchny Lake.

Greenside was run on hydro-electric throughout the 20th century, the water coming from a dam in Keppel cove which once burst, causing much devastation in the valley below....

Glasdir copper mine had a hydro electric scheme in operation before the first world war and Gwynfynnydd gold mine had one just before the second world war.

Croesor mine had a hydro plant, built during the stewardship of the quarry's last manager, Moses Kellow. The plant was opened in (IIRC) 1904. Moses Kellow invented a fair amount of the equipment used in the quarry and some evidence of the overhead electric system for the locos is still visible in the mine.

Llechwedd had and I think still use theirs. Maenofferen also had a power station.

Nenthead mines used a hydro scheme at Brewery Shaft not only for power but for compressed air too.
The finest workers in stone are not copper or steel tools, but the gentle touches of air and water working at their leisure with a liberal allowance of time.

LLechwedd have recently installed a new generating set in their power station. However, they are going to export all their power to the grid whilst buying in power for their own requirements. I still haven't got my head round the logic of that. I can understand exporting any surplus to the grid, but not all of it!

The power station (at Blean y Cwm) was put out of use many years ago and the building converted to an outward bound centre (or similar). Recently, the pipe was renewed down from Llyn Croesor to the power station (the pipe is buried now, most of the original piping was above ground). The power station has ben re-equiped and now makes a modest contribution to our energy needs. This is proper sustainable energy, not bloody windmills! I will try and find out it's current output.

My cynical money would be on them selling the hydro-generated electricity at a "green" premium whilst buying fossil-fuel generated electric at a cheaper price for their own use.....

Don't forget the North Wales Power Co. with their 1906 generating Station at Cwm Dyli - which was built with the intention of supplying Oakeley, Pen-yr-Orsedd, Penrhyn and Dinorwic, amongst other industries. Their promotional plan is quite interesting. I had a tour of the station before it was replanted - three of the original generators and peltons were there, along with the switchboard. While I was there they manually synchronised one of the generators with the grid - fascinating! The same year I had a tour of Maentwrog Station - you could almost have eaten your dinner off the floor - fantastic.

I have photos taken at the time, are they relevant enough to post on here?

Cheers

Would really like to see the photos Graham. My parents lived in the Gwynant in the late 60s and early 70s and it was always a contentious point that the power station opened in 1906 but that the valley itself only got mains electricity more than half a century later!

What year was that Graham?

I didn't actually record anywhere the date I was there, but it was around 1980-1985

Cwm Dyli was replanted between 1988 and 1989, Maentwrog between 1991 and 1992.

[See "Hydro-Electricity in North West Wales" Dewi W Thomas for more detail, but his descriptions of the quarry arrangements need treating with care.]
