SUMMARY

Prices remained relatively stable for the majority of the week, with most contracts trading within a narrow range of previous settlements.

Any increases from a series of unplanned Norwegian gas pipeline outages were capped by a consistently high amount of renewable electricity generation for a good portion of the week.

Wind power was the main source of support, with upwards of 60% of the UK’s total electricity demand being supplied by turbines in the early part of the week.

European storage injections are also proceeding at a strong pace and are well placed to meet the EU’s target of 83% well before the December 1st final deadline.

As the EU and US align on rhetoric regarding an accelerated phase out of Russian gas imports, pressure on finding alternative sources will undoubtedly increase and could drive further market volatity in the months to come.

Say 'No' to cold calling on business energy

Unfortunately, business electricity and business gas customers in the UK are bombarded with unsolicited cold calls on a daily basis.

This unscrupulous approach does not offer the business energy customer an impartial view on the market and the price offered is more often 20-30% above the current retail price for electricity or gas.

At Energy Advice Line we strongly advise customers to not accept these offers and follow our simple steps to ensure that they are not locked into an uncompetitive contract.

Join our cold calling campaign here, and spread the word to say 'no' to cold calling on business energy!
