OTTAWA, July 22, 2013 /CNW/ - Hydro Ottawa, along with other local
distribution companies throughout Ontario, is participating in a
province-wide exercise to ensure emergency preparedness for our power
On July 23, the Independent Electricity System Operator (IESO) will
conduct a voltage reduction test.
Voltage reduction is an emergency operating measure that the IESO can
employ in order to protect the reliability of the power system or to
avoid the need for rotating power outages when the demand for
electricity in the province exceeds supply. The IESO performs this test
every 18 months.
Brief voltage reductions of this scale are not noticeable to most
customers except for the possibility of a slight dimming of the lights.
The test will consist of two exercises: a 3% voltage reduction between 9
a.m. to 10 a.m., followed by a 5% voltage reduction from 1 p.m. to 2
p.m. (EST). The exercise may be rescheduled to July 25 if system
conditions are unfavourable.
To report any disruption in power during the exercise or at any other
time, please call Hydro Ottawa's 24-hour Power Outage line at
