ON THE heels of higher oil prices, Singapore Power on Tuesday announced an increase in electricity tariffs for the period between Oct 1 and Dec.

Electricity costs will go up an average of 0.86 cents to 21.38 cents per KWh.

This adds up to an increase of between $1 and $4.20 per month for one to five-room HDB flats.

Electricity prices are adjusted every three months.

The last increase was made for the July-to-September quarter, when prices went up 1.62 cents to 20.52 cents per KWh.
