Energy Regulation

Government Intervention

Government Intervention Increases Prices

This first chart below shows the power of competition and independent regulation.

British Gas was privatised, and Ofgas created, in 1986 with electricity and OFFER following around three years later. Investment in coal and nuclear electricity generation had previously been very inefficient but it rapidly got much better. But government re-interference in the energy market began around 2003 as oil/gas prices rose and the government (and less than fully independent Ofgem) responded by introducing quotas and capacity payments.

This next charts show what happened after 2003. Typical annual combined gas and electricity bills increased from around £590 in 2004 to £1420 in 2013. The first chart shows trends in the size of the main components of the cost of providing energy to the home. The steepest increase was in government-imposed costs - the red line.

The second chart includes the same data but shows how they added together to create the total cost.

These two charts show that a very large part of the pre-2013 increase in domestic fuel bills was due to government/regulator imposed costs (the red line in the charts) including investment in new transmission capacity, the £2 billion pa Renewables Obligation and the 2.2% Non-Fossil Fuel Obligation. Energy company profits (the purple line) have also risen and are now typically around £100 pa per household. Wholesale oil/gas prices (the black line) rose sharply from 2004 to 2006 but have risen by only around £100 pa since then. Note, however, that part of this increase is likely due to the policy decision to switch away from cheap coal generation to more expensive gas-fired power stations.

The figures underlying the above charts are in Note 1 below.

Ofgem subsequently published a further chart containing similar data from 2009 to 2014. You can find it on this web-page.

Increased Regulatory Complexity

Successive governments' desperation to react to public concern about energy prices, climate change, fuel poverty and energy generating capacity led to them regularly heaping additional duties on Ofgem. The following chart has been prepared by the Centre for Competition Policy at the University of East Anglia and brilliantly shows how a tottering edifice of Principal Objectives, Primary Duties, Secondary Duties and Tertiary Duties has been built up over the years following the Gas Act 1986 - and Ofgem has another quite separate set of objectives etc. for its regulation of the electricity industry.

Notes

Note 1 - The figures underlying the above charts are summarised in this note:

Note 2 - The NAO reported in 2016 that subsidies for green electricity would add £110 to the average household energy bill by 2020.
