SUMMARY

The NBP rally extended into a fifth day on Thursday, with the front-season successfully breaking through (and holding above) the major psychological level of 200p/therm with Geopolitical risks continuing to serve as the primary reason for the increases.

In focus towards the end of the week was news that the Iran-backed Houthi group had seized control of the strategic port of Mokha in south-west Yemen, putting them within direct reach of the vital Bab-el-Mandeb strait.

Houthi attacks have already severely disrupted shipping passing through the Red Sea, but this latest territorial expansion will make it easier for the group to target commercial vessels by drastically reducing required launch ranges and shortening defensive warning times.

Baseload power continued on a similar trajectory to natural gas during the week, climbing higher on supply risks from multi-regional conflicts.

Generation fundamentals were unchanged however, with strong renewable output serving as a price ceiling for the prompt and near-curve. According to data from Elexon, renewable power made up 58.7% of the generation mix on Wednesday.

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!
