‘Controlled Load 1’ and ‘Controlled Load 2’ are tariffs that apply to specific appliances that are permanently wired back to the meter such as hot water heaters or swimming pool pumps. Supply for a controlled load is only available at certain hours during the day, usually late at night. The difference between Controlled Load 1 and 2 is the hours for which supply is available and the price paid. This is determined by the network company.
