No real knowledge is needed, just curiosity about how it all works.
National Grid runs the ‘NTS’ or National Transmission System right up to the high pressure gas main in your area, where British Gas takes over low-pressure distribution to your house.
Every day, month and year National Grid assesses the ‘Prevailing ?View’ - how much gas the country needs - and producers or pipeline suppliers from Norway, Russia, Europe sell their gas in specific trades via the ‘National Balancing Point’ or NBP. The buying gas traders in UK then buy their gas at Day-Ahead, Month-Ahead or even Year Ahead prices. They all sign up to what is known as the ‘Network Code’ - which defines the rules for buyers and sellers.
If a buyer cannot fulfill their side of a trade or a seller cannot deliver, the NBP ‘balances’ the trade and the end of each ‘gas day’ with a cash adjustment one way or the other. Same happens at other gas hubs throughout Europe and also USA, where prices refer to the ‘Henry Hub’ which is actually in Louisiana and a reference point for US natural gas prices recorded by tracking gas trades on NYMEX - same principle as NBP.
You can see how US gas producers flooded their market and the gas prices tumbled from ~ $8/mcf to less than $2/mcf today.

So for Shell/Cluff the name of the game is to discover, develop and ship gas via existing facilities to a shore terminal when it is needed by NTS, according to the Prevailing View created by National Grid - in other words, keep the whole system in balance.
The NBP concept spawned the proliferation of private gas-trading domestic suppliers who constantly buy and sell at wafer-thin margins depending on their own forecast of weather etc. Some go bust because they can’t balance their trades or, more likely, because their billing systems/meter readings fail to bring in enough revenue.
