Public utility rates approved by the BCUC are generally considered permanent, unless they are specifically identified as interim rates.

Permanent rates continue in effect indefinitely unless they are approved with a time limit, which is not common. Utilities generally prefer apply for new rates if their costs are rising, for example in times of inflation. But there are circumstances where a utility has an incentive not to apply for new rates; in these cases the BCUC may (but need not) direct the utility to apply for new rates.
