This report by Ember explores the potential for an electricity interconnector between Europe and North America to enhance grid security and efficiency as both regions decarbonise. The analysis suggests that differences in time zones and weather patterns—specifically uncorrelated wind, temperature, and rainfall—could provide significant arbitrage opportunities and system resilience, potentially offering a more cost-effective solution than nuclear power or hydrogen.

This policy brief by Ember argues that Europe must double its electricity interconnection capacity over the next ten to fifteen years to meet climate neutrality goals and ensure security of supply. It highlights a gap between current expansion plans and actual power system needs, warning that slow project timeframes—averaging nine years—could create bottlenecks for wind and solar expansion.

The report 'Coal To Clean' by Ember (May 2018) analyzes the UK's transition away from coal power, concluding that the country is on track to phase out coal by 2025 without the need for new large gas-fired power plants. It argues that renewables, interconnectors, and small peaking gas plants can provide the necessary capacity and backup, allowing the UK to avoid a 'gas bridge' and move directly toward clean power generation.
