For accounts/properties connected prior to 2007 the invoices are dated every six months. Those connected in 2007 and after are dated every three months.

Billing Period – The period the invoice covers. The capacity charge is a monthly charge billed in arrears; the months being billed with this invoice are included in the billing period.

Remaining Balance – This is the total capacity charge amount remaining for this property. It consists of all outstanding invoices including Past Due Balance, the Invoice Amount For This Billing Period and the Future Invoices for the remaining 15-year billing period.

Discounted Early Payoff Amount – This is the amount to pay if you wish to pay your account off in full with one lump sum payment. It is the present value of all outstanding invoices.

This may delay your next invoice.
