LONDON Dec 15 Centrica Storage Limited said on
Thursday it had launched a market consultation on reducing the
minimum storage capacity at its Rough gas storage site in
Britain, amid concerns about its ability to deliver gas.
CSL said it is allowed to apply to the energy market
regulator Ofgem to reduce the capacity when there has been, or
is expected to be, a substantial change in Rough's physical
For such an application, CSL has to launch a market
"The primary aim of the consultation, affecting the
2017/2018 storage year, is to ensure CSL is not required to sell
more storage services than Rough can physically deliver," the
operator said in a statement.
The consultation document sets out a range of projections
for Rough's physical capabilities in 2017/18, based on the
availability of its wells for injection and withdrawal of gas.
They also include one scenario where there are no wells
available for injection and withdrawal.
Britain's main storage site, Rough, in the North Sea, is
over 30 years old. It only resumed some gas withdrawals last
week after its operations had been restricted last year due to
potential issues with well integrity.
This shutdown highlighted the vulnerability of the country's
gas storage capacity.
CSL said it would provide the market and Ofgem with specific
information about Rough's forecast capabilities on or before
Feb. 28, 2017.
