Forest Pennant, a natural stone company based in the Forest of Dean, Gloucestershire, UK, recently switched on its on-site micro-hydro generation turbine.
Harnessing the power of the River Lyd, the turbine installation will produce around 50 MWh of electricity over a 12 month period, meeting more than a third of the company's usage, a press release states.
Using a crossflow turbine from Ossberger, Forest Pennant will generate around 12 kW of power.
The electricity generated by the hydro turbine is fed into the distribution network of the stoneworks, and any surplus is exported to the national grid.
Forest Pennant managing director, Nick Horton, estimates that the net contribution to the company, when the government feed-in tariff has been added, will be in the region of GBP15,000 (USD24,000) per annum.
