Capacity at Britain’s largest natural gas storage site has been permanently cut after the closure of part of the site which houses six of the site’s 30 wells, operator Centrica Storage said on Friday morning.

The removal of the installation means Rough’s withdrawal capacity will sink by 3.3million cubic metres (mcm)/day.

Capacity be around 37mcm/day at the start of this the winter, which decreases gradually as gas is removed from the site. The loss of 47/8A will not impact the site’s operations for this coming winter, Centrica Storage said.

“After 40 years of service, Centrica has concluded that, having regard to its age, condition and design-life, it is no longer feasible to operate the 47/8A installation. It is therefore permanently withdrawing the installation from service,” the company said in a REMIT update.

The operator began maintenance of the installation in August 2015, later withdrawing it from service in March of this year.

Only four of the installation’s wells had been active up to its shut-down. The remaining two wells had been plugged several years prior.

All injections at Rough ceased in July as Centrica Storage brought the ageing site offline and began a period of in-depth testing on its wells.

On 22 August, the company said that 20 of the sites wells would be available for withdrawal from 1 November; when stocks are set to be 55% lower than the previous year due to the halt in injections. thomas.rodgers@icis.com
