Abstract: Solar power generation by consumers is growing but not necessarily benefiting the utility (power generation and transmission) firms. Reducing the power demand, it hinders the coverage of utility costs with reasonable retail electricity prices. Utilities in practice tend to raise retail prices, unintentionally reducing both affordability and demand of electricity, and are hence said to be caught in a utility death spiral. The reduced affordability adversely affects financially challenged consumers that cannot invest into solar power. Environmentally desirable solar power paradoxically can be socially undesirable. Facing this paradox, market regulators are challenged to keep retail prices low within the current pricing mechanisms. We provide a novel revenue maximization formulation for a regulated utility and reveal the interaction between optimal retail price increases and growing solar power adoption. Iterating with this interaction, we analytically explain when and how the utility death spiral occurs. We consider new pricing mechanisms that involve a buyback price and a subscription fee paid only by harvesters. The fee mitigates the optimal retail price increase by allowing for the coverage of fixed costs in part. We find appropriate values for the buyback price and subscription fee to respectively slow or stop the death spiral. These mechanisms and values are important not only for the utility and its regulator, but also for all electricity consumers.

Bio: Metin Çakanyıldırım is a Professor of Operations Management at School of Management at University of Texas at Dallas. He focuses on making good decisions in the presence of uncertainty. He employs mathematical models to formulate problems arising in real-life contexts and then uses optimization methods or heuristics to come up with decisions. He has investigated problems from various contexts: capacity, inventory management, transshipments, contracts, forecasting and cargo overbooking.
