The enterprise confirmed the developments in a statement saying the electricity system continues to be severely constrained.

“The load shedding will be implemented from 10:00 until 22:00 today to manage dam levels at its pumped storage schemes,” read Eskom’s statement.

“Implementing lower stages of load shedding throughout the week helps us prevent severe load shedding later in the week.”

Eskom added that, the pumped storage schemes which use water to generate electricity, was experiencing low dam levels.

The power utility said the dam levels were low because the utility was not able to pump the water back to full capacity over the past weekend.

“This is mainly because they were in use over the weekend to meet demand. Ordinarily, the weekends are used to pump our dam levels to maximum capacity in preparation for the forecasted increased demand in electricity during the week,” said Eskom.

The power utility also said, this being the maintenance season, the enterprise expected the power grid to remain constrained for the rest of the summer.

Eskom calls on consumers to switch off geysers, air conditioners, pool pumps and all non-essential appliances throughout the day to reduce electricity demand,” pleaded the utility.

“We also request workers to switch off the lights, with the exception of security lighting when they leave office buildings this evening and to ensure that air-conditioners are switched off over night.”

Eskom said, commercial customers, particularly shopping centres and office blocks, can make the biggest difference by switching off non-essential lights and not to leaving office equipment such as photocopiers and computers in standby mode after hours.
