One extra unit can change your FESCO bill a lot. For a protected home on 1 kW, 200 units works out to about Rs 3,557 in the BillHelp.pk calculator. At 201 units you move to unprotected rates and the estimate jumps to about Rs 8,755. Going past 200 also costs you protected status for the next six months, so watch your meter in June and July.
