John Horgan says he will freeze BC Hydro rates if the NDP is elected May 9.
Horgan made the pledge just after he promised to eliminate tolls on the Port Mann and Golden Ears bridges.
The NDP's announcement comes barely a week after electricity rates jumped nine per cent.
BC Hydro announced in November that rates would climb another 16.5 per cent over the next four years.
Horgan said B.C. residents have no choice but to pay the increases in order to power and heat their homes.
He said freezing rates and removing bridge tolls will make life more affordable for British Columbians.
The NDP is hoping an election campaign focusing on affordability will move the party from the Opposition benches — to power — after 16 years of Liberal rule.
