The amount of natural gas used by power plants to generate electricity was 7.4% lower in 2021 compared to the previous year, mainly due to a Co Cork power plant being offline, according to the Central Statistics Office (CSO).
A fault at the gas-fired Whitegate power station meant that it was offline for most of 2021.
It comes after the British multinational energy company Centrica announced in July that Bord Gais Energy’s operating profits grew 74% in the first half of this year to £33 million (or around 39 million euro), partly due to the return of Whitegate in December 2021.
