Performance Incentive Mechanisms for Strategic Demand Reduction
The report examines performance incentive mechanisms (PIMs) designed to motivate US utilities to implement strategic demand reduction (SDR)—a combination of energy efficiency and demand response that optimizes the electricity system. Analyzing seven state case studies, the authors find that while PIMs are effective, the potential for cost-effective load flexibility remains largely untapped. Most current PIMs focus on 'shape' (long-term demand adaptation) and 'shed' (peak demand reduction) services, with limited focus on 'shift' (moving demand between times of day) or 'shimmy' (real-time grid balancing). The report argues that durable, long-term incentives with periodic updates, supported by complementary policies like decoupling and time-varying rates, are most effective at aligning utility business models with public interest and decarbonization goals.
