Soaring demand
There is currently a stronger than usual demand globally for gas, yet European gas storage levels are unusually low for this time of year, especially in Germany. This is due to colder than anticipated weather, lower wind speeds and conventional generation outages. As such, Europe has simply not been able to replenish its gas storage levels, which are currently at around 72% versus 94% last year and a 10-year average of around 85%2. Moreover, lower hydro conditions in Latin America have seen supplies of liquid natural gas (LNG) diverted to that market, while Asia is outbidding Europe and the UK for LNG – particularly after the recent order in China for state-owned enterprises to stock fuels “at any cost”3. Flows through NordStream 2, a new export gas pipeline running from Russia to Europe across the Baltic Sea, could alleviate the pressure on natural gas prices, but with additional geopolitical consequences.
A perfect storm of factors
Higher power prices will push up customer bills
In the UK, suppliers that have not hedged against rising prices run the risk of not being able to afford to buy either electricity or gas in order to serve their customers. Note the majority of suppliers don’t actually produce their own electricity or gas and have to buy it. Indeed, 12 suppliers representing around 20% of the UK total and affecting more than two million customers have already failed, with more expected. Such is the concern within the UK industry that regulator Ofgem recently appointed a special administrator to deal with the possible failure of larger suppliers.

Low levels of wind and solar
One pitfall of renewables is that the wind doesn’t always blow and the sun doesn’t always shine. In the past three months the wind has not been strong globally and in the UK has been at its slowest for 70 years. These are issues we can address, however, and we have been getting better at doing so over time. Notably, these have included: investments in the power grid; the use of hydro storage, ie filling the reservoirs; increasing the use of battery storage, although only for short duration; using interconnectors to borrow electricity from our neighbours; and using gas as a back-up. Indeed, some countries happily operate stable power systems where non-carbon emitting generation accounts for over 75% of electricity without issues. But UK renewables on average account for only 30% of electricity generation in a year – not usually a major problem but in combination with the aforementioned factors have caused issues.

EU power market redesign
What about oil?
What can be done?
- Build more renewables – at a rate fast enough to keep up with the closure of the carbon-emitting generation. A notable barrier to growth has been planning consent as local communities while supportive of renewables in theory remain resistant to obstruction of views – behaviour described as “Nimby” or Not In My Backyard.
- Increase storage capacity for both gas and pumped hydro, investing in interconnections and grid balancing.
- Consider a new pricing mechanism for electricity. Currently, the electricity price is determined by the price of gas in Europe. This made sense in the past, when gas or coal accounted for the vast majority of electricity generation, because it was representative of the cost of the system. But as renewables grow it makes more sense to have 80% of renewable generation costing €30-€40/mwh, and 20% of gas generation costing a highly variable €30-€80/mwh, but with the latter determining the price for all. In this scenario, the tail should stop wagging the dog.
