How we work it out

  • One home: urban, single phase, 2 kW. It uses 100, 200 or 300 units a month.
  • The bill is energy charge plus fixed and customer charges, from the tariff in each order. It does not include electricity duty, tax or fuel surcharge.
  • “In today’s rupees” uses the consumer price index of MoSPI (all India, general). We use the average of the months of each financial year. For 2026-27 we use April to September.

What we could not confirm

  • The orders list the slab rates but do not say in words that each rate applies only to the units in its slab. We assume it does. Check this on a bill.
  • Our bills do not include the meter rent. The orders show Rs 20 a month in 2015-16 and Rs 40 a month in 2017-18 and 2022-23. We could not read it for the other years.
  • The 2021-22 order gives its date as 26 February 2021. The SSERC website gives 26 March 2021.
  • We found no fuel surcharge, electricity duty rate or State free-units scheme for homes in the orders.
