Blueprint Background

Least Worst Regrets analysis

Worst Regrets analysis is a decision-making tool that makes recommendations based on which options/strategy produce the least “regret” across all of the analysed. Thus, all investments that feature in the Least Worst Regret approach would be identified as prudent investments and the regulator may have some confidence in the merits a priori of committing the consumer to recover their cost.

Welcome to the Power System Blueprint!

Climate neutrality requires the full decarbonisation of the power sector. As this is one of Europe’s biggest challenges today, there is a need for speed.

The Power System Blueprint lays out how to design the regulatory context to achieve a clean, reliable, equitable and affordable European power system by 2035. The Regulatory Assistance Project (RAP) pulled together the latest insights to support regulators, NGOs, governments and anyone pursuing a decarbonised European power system.
