In a recent case, a company was planning an energy load reduction programme and also an expansion of their operations. The load reduction, due to the intervention of heat pumps and efficient lighting replacements, resulted in sufficient electricity load reduction to eliminate the need to request, from Eskom, an increased electricity supply allocation, avoiding the possibility of subsequent associated capital expenditure and implementation delays.

The conclusion from the post- implementation M&V performance assessment Report on Jhb Hotel, compiled by Eskom approved M&V practitioner, Tshwane University of Technology (TUT) is as follows:

The project - as implemented by ESCO Voltex and measured and verified by TUT team - was evaluated with a performance of 100% against the proposed target of 266 kW peak demand savings.

If the guidelines are followed using quality heat pumps together with an acceptable installation practice, your customer should have a load reduction and energy saving installation that meets the project objective in all respects.


Take note

  • Heat pumps result in load reduction.
  • Installing heat pumps depends on space and aesthetic constraints as well as the effect on load reduction.
  • By following a particular sequence of operations and methodology, a soundly structured energy saving solution can be achieved.
