In this latest OIES podcast from the Electricity Programme, Dimitra Apostolopoulou engages in a discussion with Tim Schittekatte, a Senior Director at FTI Consulting and a part-time professor at the Florence School of Regulation, about his latest paper titled "Time-Varying Electricity Pricing is a Powerful Tool – But Without the Grid in the Loop, It Risks Going Off The Rails" which was part of the recent Oxford Energy Forum on Electricity Prices and the Energy Transition: Economic Efficiency, Social Equity, and Climate Alignment. The discussion centres on Tim's research, which examines how dynamic retail rates can help balance renewable energy supply and demand while lowering consumer costs. However, without integrating grid capacity into these pricing models, a localised surge in usage, such as mass electric vehicle charging, could overwhelm the distribution network. To address this, we need to compare different pricing methods and their impact on economic efficiency and social equity. Ultimately, the dialogue emphasises that future market designs must align financial incentives with the physical realities of the power system to ensure long-term stability.
