National Grid forecasts showed demand hitting 309 million cu m on Wednesday before increasing to 330 million cu m Thursday then dropping to 320 million cu m Friday, compared to the seasonal average of 295 million cu m.
But the system was balanced at 10:00 am, with physical flows running at 308 million cu m/d despite no withdrawals seen from medium-range storage reservoirs.
The within-day and day-ahead contracts were trading at 55.50 pence/therm and 55.30 p/th respectively Wednesday morning, both broadly in line with the day-ahead assessment of 55.50 p/th from last Friday.
There were strong flows from the Norwegian Continental Shelf Wednesday morning, at 136 million cu m/d according to Norwegian gas operator Gassco.
UK Continental Shelf production was due to be boosted by the partial restart of oil and gas flows through the Forties Pipeline System on Tuesday afternoon according to Ineos, with gas production at both the Elgin Franklin field and Greater Britannia Area restarting as a result.
But the restart of flows via the North Morecambe sub-terminal was delayed over the Christmas period, with flows now expected to restart at the beginning of Thursday's gas day, according to operator Centrica.
