When you sign up for the Equalized Payments Plan (EPP), we estimat the annual cost of your electricity use of the previous year and divide it up into 12 equal monthly installments. That way you pay your annual electricity bill over the whole year.
You can also pay every two months for the amount of electricity you actually use. Since next-generation meters were deployed, customer consumption is read on on the billing date (which follows a pre-established schedule). Bills are based on these readings.
