UK Carbon Tax Could Add 10% To Energy Bills, New Report Finds

Vicky Ellis, Energy Live News

The UK’s tax on carbon could add 10% to energy bills, analysts at investment bank Macquarie believe.

In an equities research report, they suggest that from an “environmental, economic and taxation point of view” it is “counterproductive” and “therefore unsustainable”.

The carbon price support is effectively a tax levied by the Treasury on fossil fuels. Announced in the 2011 Budget, the price floor kicked in from 1 April 2013 and it puts a price on the emissions of large firms’ energy use.

The bank report suggests the mechanism has “hardly affected” the UK power market at present but this could change in the next six years.

It states: “The carbon price support mechanism… will increasingly affect market behaviour by 2020. We see a £15-20/MWh difference between power prices with and without this floor – which is c.10% of the retail bill.”

Future power links with the rest of Europe could make UK-based fossil fuel more expensive, argues the report, suggesting firms will buy cheaper, possibly more carbon-heavy energy from the continent thus making the carbon tax ineffective.

The report goes on: “We see the arbitrage between German and UK power prices rising to neatly £40/MWh by 2020. This means a new interconnector could have a ROIC (return on investment capital) of c.20% and a 4-year payback. This means that high carbon emitting European generation could eventually supplant lower emitting UK plant.”

However the Treasury disagreed the cost would go up 10%, pointing to DECC figures which put the price at an extra 7%.
