There is a very crucial need for a benchmark in order to avoid abuse. The benchmark should be your consumption at a time you did not know about any intention or plan of Government to absorb part of your electricity bills for a period of time so that it can give a fairly accurate and true picture of your regular consumption. Since the reliefs are to take effect from April 2020, and the announcement was only made in April, the use of the preceding month, March 2020 as the benchmark is most appropriate. Once your true (uninfluenced) monthly consumption is known, it will help determine or approximate your subsequent monthly consumptions (especially, during the duration of the relief).
