Rough gas storage closure (2017)
Centrica closed Rough, a depleted North Sea gas field that held about 70% of the United Kingdom's gas storage capacity. The facility had been used to balance winter demand for decades.
UK storage capacity fell sharply, leaving the country more reliant on imports and liquefied natural gas.
The closure became a reference point in UK energy security debates, especially after the price spikes of 2021 and 2022.
It shows what losing a large storage facility means for a market that depends on winter flexibility.
