Britain’s Oil and Gas Authority (OGA) has given consent to Centrica to increase storage capacity at Rough, the country’s largest gas storage site, the company said on Monday.
The OGA decision will enable the site to increase its storage capacity by around 15 billion cubic feet or 4.5 terrawatt hours (TWh), Centrica said in a statement.
In March the company said the amount of stock in the Rough reservoir could be limited to a range of 29 TWh to 32 TWh for up to six months after a potential problem with well integrity was discovered that could affect all wells.
The maximum stock level that Rough reached last year was 41.1 TWh.
Centrica said that the limitation on Rough’s storage imposed earlier this year remained in place and the OGA consent did not affect this.
