Electricity bills in Pakistan are calculated using consumed units, tariff slabs, fuel adjustment charges, taxes, meter rent, TV fees, GST, and other government surcharges.
WAPDA electricity providers such as LESCO, FESCO, MEPCO, IESCO, GEPCO, PESCO and K-Electric use different tariff structures depending on residential, commercial and industrial consumers.
Electricity bills usually increase during summer because air conditioners, fans, refrigerators, water coolers and other appliances consume more electricity.
