Brihanmumbai Electricity Supply & Transport Undertaking [Best] — High electricity bill

I am customer no.[protected]*0.

For the period of 27/04/2021 to 25/05/2021 I have received electricity bill of Rs.1443 with units consumed as 231kWh.

My electricity consumption in previous year has not crossed even 108 kWh. I haven't bought any new electrical appliance, so this sudden jump in consumption is beyond my understanding.
