The Need for Market Transparency
on Voltage Levels

---

• It has been shown that voltage can have a significant impact on customers' electricity bills.

• Random measurements in the field suggest that there may be a growing divergence in some areas between the nominal voltage of 240 volts, and the actual average daytime voltage, which appears to be around 3 per cent above nominal.

• A more reliable indication of customer voltages can be cheaply obtained by ORG and the OCEI arranging with Victoria's computer network systems administrators to log the mains supply voltage being presented to their UPSs (Uninterruptible Power Supplies). I have already publicly called on the System Administrators Guild of Australia to ask their members to do just that. They could publish the results on their web site at very modest cost, for which the OCEI and/or ORG should be prepared to pay a reasonable fee for the service provided in the interest of market transparency.
