Welcome

Heidra is a Dartmoor based company with the core aim of developing well-engineered small hydro electric installations to optimise the power generated from water whilst minimising the local environmental impact.  Typical sites have a rainfall catchment area greater than 3 square kilometers and a head of above 50 m.  Key projects in this area are:

• Development of accurate resource assessment tools to predict and measure the flow-duration curve at a given site.  The work is part funded by the Dartmoor National Park and is performed in conjunction with WHS and DARE.
   
• Manufacture of an efficient, low-cost turbine for high-head, low-flow sites to maximise power capture from the available resource without the environmental impact of reservoir storage: contract awarded from RE4D;
   
• Development of a Small, High-Head Hydro (S3H) demonstration site: Environmental Impact Analysis in progress.
