In Episode 34 of the podcast "Redefining Energy Tech" (part 2/2), host Michael Barnard engages with Professor Bent Flyvbjerg, author of "How Big Things Get Done," to delve into the intricacies and strategies of megaprojects, focusing particularly on the comparison between pumped hydro storage and battery systems. The conversation emphasizes the importance of modularity and repeatability in large-scale projects and highlights various risks associated with construction, including data deficiencies and stakeholder management.    Professor Flyvbjerg introduces the concept of the 'window of doom,' underscoring the necessity of swift project delivery to mitigate risk. The episode explores the advantages of modular construction as evidenced in projects like the Tesla Gigafactory and renewable energy sectors, contrasting these with the prolonged timelines typical of nuclear power plant constructions. The discussion provides actionable recommendations, urging listeners to review critical risk management heuristics and the variance chart from Flyvbjerg's book. These insights are aimed at enhancing project management practices in infrastructure development.  Listeners are encouraged to understand base rates and project risks, utilize heuristics for successful project management, and consider the significance of the variance chart in Chapter 9 of Flyvbjerg's book. The episode concludes with a call to develop personal heuristics for managing megaprojects effectively.
