My monthly bill is usually between 1300 and 1600bht, I only use A/C in my bedroom to cool it for a few hours then the ceiling fan takes over, downstairs has never needed A/C, but this year it would have been helpful, downstairs is open plan with 4 ceiling fans, usually 2 on all day.
The bill this year for March/April was 2100bht, for April/May, it was 2400bht..
2 of my friends doubled to over 5000bht.......😬
