Turbine efficiency monitoring in the UK

By monitoring the efficiency of a turbine, we supported a UK water company to maintain maximum electrical output.

Found 84% efficiency

Rated shaft power output of 320kW at 84% hydraulic efficiency, but found best performance to be 82%

Optimised 82% efficiency

Optimised operation of inlet guide vanes to ensure maximum efficiency of 82%, avoiding 58% lows

Identified £11K savings

Average efficiency identified as 73% but if increased to 80% would save at least £11,000 per year

More about our work with this UK turbine

The turbine in question – a fixed speed machine (1016rpm) – runs without any human intervention and is controlled via flow rate modulation using inlet guide vanes.

Utilising our FREEFLOW pump monitoring system, we were able to immediately identify if proposed changes were proving effective or not. Our system tracked savings and the financial consequences associated with any changes.
