The RPI Research Group is currently developing a programme of work to explore the evolution of decision-making processes for major infrastructure projects. It will investigate the role and effectiveness of independent regulators in this process, identifying the conflicts and ambiguities that have emerged from increasing tensions between the traditional role of an independent regulator and the emerging strategic priorities of government. The programme seeks to draw conclusions about the impacts that these tensions have had on accountability, forecasting in the context of uncertainty, adaptation to changes in technology, and incentivisation of investment; asking if a new decision-making paradigm which reconciles the often conflicting priorities of government and independent regulator, while capturing the long-term nature of such investments, is required.
