French regulates the prices charged by the dominant companies in the gas and electricity markets: electricity firm Power NI; SSE Gas in Belfast and the west; and Firmus in the Ten Towns network.
Price regulation decisions are normally made twice a year in October and April.
The regulator said the energy companies could ask for additional ad hoc price reviews if rising wholesale costs start to become unmanageable.
That happened during the early stages of Russia’s invasion of Ukraine when prices spiked spectacularly.
French said at that time wholesale gas prices rose from about 60p a unit to as high as £9, with an average of £5 for a considerable time.
The moves during the current conflict have so far been less dramatic, with wholesale gas prices going from about 70p a unit to £1.70.
