Power sectors across the globe are no longer characterized by simple one-way transactions with utilities supplying electricity to customers. These traditional supply-side resources are now competing with customer-side resources, such as energy efficiency and distributed generation, options that also carry numerous societal, utility system, and consumer benefits. The Hong Kong Consumer Council invited Max Dupuy to present international experiences from Europe and the United States to demonstrate how policymakers can create “a level playing field” for all resources. With a regulatory structure that allows all resources to compete on equal footing—ideally coupled with thoughtful integrated resource planning and utility incentives—energy efficiency and distributed generation can lower costs, risks, and damage to the environment.
