IESO to Conduct Province-wide Voltage Reduction Tests on March 6

The Independent Electricity System Operator (IESO) is conducting a routine voltage reduction test today Tuesday, March 6 as part of mandatory testing of its emergency operating measures. The test is not expected to impact the public.

The first reduction is from 9 – 10 am at 3% voltage reduction and  the 2nd is from 1 - 2 pm at 5% voltage reduction.

Voltage reductions lower demand quickly and minimize the likelihood of service interruptions, helping the IESO maintain the reliability of Ontario's power system during a variety of unplanned occurrences.
