Energy efficiency county council – the challenges:

As part of the Irish Government’s National Energy Efficiency Action Plan (NEEAP) , which seeks a 33% reduction in public sector energy use, Mayo County Council called on ResourceKraft to look for energy reductions within both its water pumping and treatment facilities. As a result – energy efficiency county council’s problem was looked after.

Mayo County Council deployed the Advisor system to monitor energy usage at its water pumping and treatment facilities. Data on energy usage and throughout was measured at a pump level. After a 6 month study, the following was identified:

  • The identity of the most inefficient pumps/motors as measured by energy usage versus litres pumped. These pumps will be rotated out and replaced with higher efficiency plant at the earliest possible opportunity
  • That some of the motors were consuming more than their rated power (approx. 7-11% over rating)
  • That running the pumps to fill uphill storage reservoirs on cheap night rate electricity, would save very considerable sums on electricity costs and pay for the replacement of inefficient plant
  • New, optimised running logic that minimised the energy costs per litre pumped
“ResourceKraft provided a enterprise class energy monitoring system that reports the energy consumed on each site on a 15 minute basis. With the data gathered and analyzed by ResourceKraft, Mayo County Council could then put a plan in motion to implement operational savings. Our pumping schedules are kept in line thanks to Advisor’s ‘Hours of Operation’ alert feature.”

Report Card:

  • Cost savings of up to €139,000 were identified at two sites
  • Inefficient  plant identified for replacement
  • How it was being used
“From the data gathered by ResourceKraft and presented to us on their M&T system Advisor, we have managed to significantly reduce the annual running cost of our pumping station at Lough Mask.”
