Measurement and verification methodology for an energy efficiency improvement on the cooling auxiliary equipment in the mining industry

Cooling auxiliary equipment at a mine uses excess electrical energy and contributes to the high demand of electricity in South-Africa. By implementing Energy Efficiency Demand Side Management (EEDSM) measures on the auxiliary equipment; the electrical power demand during the day can be reduced and thus assist to create an overall power reduction in the national demand. Measurement and Verification (M&V) is needed to determine, quantify and verify the impact of these projects on energy use for the stakeholders. M&V should be an independent, impartial party that provide answers to questions such as: : What was actually done/installed during the DSM project? : What was the actual impact of the DSM project? In order to answer these questions a methodology was developed that should comply with SANS 50 010 / IPMVP requirements. This paper will focus on an M&V methodology for energy efficiency on cooling auxiliary equipment and the results of a case study will be given in this paper.
