Hydro

Full assessment and development services for micro hydro sites. Heidra has developed detailed resource assesment methods to establish the parameers needed for the efficient development of true run-of-the-river hydro systems.

Following research into turbines that fully realise the hydro potential of upland sites, Heidra is pleased to announce the production of the OptiFlow T17. The T17 is a turgo tubine with variable flow technology, allowing it automatically absorb more flow (and generate more power) during and after rainfall events.

Wind

Supply of wind measuring, monitoring and assessment services for small to medium scale wind turbine sites. The assessment uses scaled down techniques developed for large wind farm developments. It includes full, hourly correlation with reliable long term met office data to accurately predict average annual revenue in as little as 2 months.

The monitoring equipment uses industry standard anemometers and wind vanes to accurately measure wind speed. Installations use masts designed to appropriate BS standards. All ground anchors are tested on-site to hurricane wind force loads to ensure trouble-free monitoring.

Mobile phone modems embedded in the equipment allow remote dial-up to monitor operation and achieved correlation accuracy.

Assessment procedures account for the dominant obstacles around a site to determine the optimum position and height of a wind turbine.
