Bord Gáis Energy’s operating profit rose 74 percent in the first half of the year, it appears.
Meanwhile, customers struggling with the cost of living had to endure a series of surges in their bills.
The Irish unit of the British Centrica had an adjusted profit of € 39.5 million in the first six months of this year.
This is an increase of 22.7 million euros in the same period last year.
The company raised its prices three times in the past year – in August and October 2021 and in April this year.
Bord Gáis Energy’s customer base increased slightly to 513,000.
The company maintained that the improved performance was due to the recommissioning of the Whitegate power station in Co Cork late last year, which allowed it to take more advantage of rising energy prices.
Parent company Centrica announced group profit of £1.34 billion (€1.6 billion) for the six-month period.
Separately, households have been warned that wholesale gas prices may continue to rise.
The Russians have left the gas markets guessing whether they will further reduce flows to Europe, keeping gas prices at a high level.
Gas traders have been closely monitoring developments around Nord Stream turbines since mid-June, when Russia’s Gazprom reduced flows to 40% of the pipeline’s capacity.
