Our sister company, TLS Hydro, a hydropower development company, manages and operates hydropower stations throughout the UK.

We currently operate 8 hydropower plants in the following locations:

• Scotland
  • Balgonie
  • Cleghorn
  • Glen Forslan
  • Roshven
  • Stormontfield

• England
  • Nenthead
  • Greenholme Mill

• Wales
  • Aberdulais

More information on each of the sites can be accessed by following the links above, or on the left-hand side navigation bar.

TLS Hydro develops two basic types of site: run-of-river schemes and storage sites.

With a run-of-river scheme, part of the river is diverted from the main flow via a leat. The flow of the water then drives the turbines, generating electricity. The electricity is generated constantly, as long as the river flows.

Storage hydropower schemes are placed at lochs, lakes and reservoirs. When power is needed, the water is allowed to flow out of the lake and through a turbine.

We have carved a particular niche for ourselves with the development of hydropower stations on the sites of old mills, which used the river to power machinery. In many ways, this is easier than developing a new site from scratch. We can often utilise pre-existing leats and weirs (with a little cleaning and dredging!) and the river's 'potential' as a good hydropower station has been proved.

Redeveloping old sites means that the environmental impacts are greatly reduced. We also add fishpasses to the hydropower plants, so the impact on local wildlife is lessened.

Most of the hydropower stations predate the founding of LoCO2 Energy and are signed up to long term agreements to sell their electricity. As these contracts expire, we will look into bringing these into the LoCO2 Energy fuel mix.
