Tynddol Off-grid Hydroelectric Renovation

Renovations are complete on the offgrid property in Ceredigion. Up to this point the property used a 5kW Gilkes turbine, which had been running for over 40 years. We have installed an entirely new system with a completely new (penstock) pipe and control unit, boosting the maximum power output to 18kW. This has been achieved by increasing the head height (vertical drop), thereby increasing the pressure.



The dam has been renovated and modernised to include a hands-off flow, as per requirement; this ensures the depleted section of the river never dries up. Environmental benefits include easier fish migrations and more abundant ecology due to the now constant flow. The new system features a bespoke three phase to single phase transformer as well as a Gerry Pope Offgrid electronic load controller; the turgo turbine is provided by Hydrolite.


The family have discussed installing a hot tub as one of the additional features now available to them due to their increased power capacity.
