During a power outage the area impacted by an outage that lasts over 10 minutes will be covered by a red circle.
Please note that OH (solid coloured lines) are overhead lines, while UG (dashes)are underground feeders.
There are two locations from which Grimsby draws power, each with two incoming lines. The four feeder lines are labelled in the legend as 18M3, 18M4, 2508M3 and 2508M4. The two lines, 18M3 and 18M4, connect to the Beamsville transmission station. The other two lines, 2508M3 and 2508M4, connect to the Niagara West Transformation station located south of Grimsby.
