The boost to the gas supply is also expected to increase reserves of the fuel that have been stored for use if unpredictable weather affects supplies in the UK.
Discussing the move, Ofgem chief executive Alistair Buchanan said: "While this is welcome news, we must not forget that we are vulnerable to fluctuations in global energy prices.
"And nobody can predict with any certainty how severe a winter we may have or what may happen to global energy prices so there is no room for anyone to drop their guard this winter."
Ofgem's latest news on the gas market comes after the regulator warned customers to expect a small increase on their energy bills in the next year.
The price rise is expected to be implemented as the regulator invests £5 billion in the replacement of old gas mains and the creation of new training schemes in the sector.
