Energy justice in times of crisis: protection of consumers and market-based renewable energy investments

In response to the 2022 energy crisis, caused by the disruption of Russian gas supplies to Europe, the European Union (EU) emphasized the importance of accelerating the deployment of renewable energy to ensure supply security and lower energy prices. Paradoxically, renewable energy investments were also one of the main targets of the EU efforts to contain the hardship of the crisis. Based on the reasoning that investors in wind and solar energy received profits that by far exceeded pre-crisis levels, the EU capped their 'surplus revenues' and initially proposed to decouple electricity from gas prices. These initiatives were justified based on considerations of distributive energy justice. Yet, by interfering with revenues and the electricity market structure, the EU signalled to renewable energy investors the risk of regulatory intervention with the market basis governing their investments. Building on the arbitral practice on renewable energy and electricity regulation, this article examines the international protection of market-based renewable energy investments and critically reflects on how investment protection affects states' right to ensure energy justice in times of crisis.
