Professor Dieter Helm of the University of Oxford presented on future models for utility regulation and policy. He discussed three potential models: 1) Increasing competition by reducing natural monopolies; 2) Maintaining licenses, universal service obligations, and the regulated asset base model; 3) Establishing system operators to combine competitive and regulated asset base approaches by focusing on the minimal natural monopoly functions. Helm argued that governments are increasingly intervening in infrastructure sectors like energy, water, and communications. Emerging models involve more competition where possible, with system operators overseeing universal service obligations and regulated asset bases.
