EU Carbon Tax Looms Over UK Renewables’ Future

The United Kingdom’s burgeoning renewable energy sector, celebrated for its clean power generation, faces a looming challenge from the European Union’s carbon border tax. 

Beginning in 2026, British wind and solar farms exporting electricity to continental Europe may be subject to CO2 fees under the EU’s Carbon Border Adjustment Mechanism (CBAM). 

This policy, designed to curb carbon emissions, could paradoxically penalise renewable energy sources that produce no emissions. 

The crux of the issue lies in a specific clause of the CBAM legislation. It levies a CO2 emissions fee on imports of various goods, including electricity, unless the exporting country maintains equivalent CO2 pricing policies. 

This fee, based on a default value reflecting historic emissions from power generation, threatens to unfairly impact UK renewables. 

Industry experts and analysts have voiced concerns that this measure could undermine revenues for UK renewable projects, increase power prices in the EU, and potentially lead to higher emissions. 

Adam Berman, Deputy Director of Energy UK, stated, “It’s a problem on both sides. It disincentivises clean power in the UK at a time when we’re trying to ramp up provision of clean power, and it’s going to increase power prices in northern Europe.” 

The CBAM’s design, which applies a uniform fee regardless of the actual carbon content of the imported electricity, could make it economically unviable to export excess clean power from the UK to Europe during periods of high renewable generation and low demand. 

Analysis from Aurora Energy Research suggests that up to 3 gigawatt hours (GWh) of renewable power generation could be curtailed by 2030 due to this fee. This could potentially raise wholesale power prices in markets such as Ireland, which are heavily reliant on UK imports. 

Moreover, the potential for European countries to increase coal and gas power generation to compensate for reduced UK electricity imports could result in a rise in CO2 emissions by as much as 13 million tonnes annually. This is equivalent to the emissions of 8 million cars. 

Efforts to mitigate this issue include proposals to link the EU and UK carbon markets, thereby exempting UK power producers from the tax. However, this solution requires mutual agreement, which remains uncertain amidst the broader political complexities of post-Brexit negotiations. 

Diplomatic discussions had subsided during the general election campaign, with significant progress unlikely before the political landscape settles following the election of a new Labour administration. 

For UK businesses, understanding these regulatory challenges is crucial. Adaptation strategies may include diversifying export markets and enhancing domestic consumption to mitigate potential revenue losses. 

In summary, the impending application of the EU’s carbon border tax presents a significant obstacle for UK renewables. This underscores the need for coordinated policy adjustments to ensure the continued growth of clean energy in both regions.
