“…Systemic methods have successfully been applied in diverse fields, including the aviation industry [8][9][10], infrastructures [11][12][13][14][15], and the maritime sector [16]. These studies show that systemic methods are more capable than their analytic counterparts in identifying hazards specific to increased complexity, for example, linked to growing component interaction [9,10,12] or digital control [14,15,17] These positions study the effectiveness of systemic risk assessments in the energy sector as a largely untouched research gap. Even if complexity in energy systems grows rapidly, analytic methods remain the most prevalent ones used among both practitioners and scholars.…”

This paper argues that energy systems are becoming increasingly complex, and illustrates how new types of hazards emerge from an ongoing transition towards renewable energy sources. It shows that the energy sector relies heavily on risk assessment methods that are analytic, and that systemic methods provide important additional insights. A case study of the Dutch gas sector illustrates this by comparing the hazard and operability study (HAZOP, analytic) with the system-theoretic process analysis (STPA, systemic). The contribution is twofold. This paper illustrates how system hazards will remain underestimated by sustained use of only analytic methods, and it highlights the need to study the organization of safety in energy transitions. We conclude that appropriate risk assessment for future energy systems involves both analytic and systemic risk assessments.
