Carl Linvill opened the EUCI conference on utility resource planning by framing the current challenges faced by utility planners. The retirement of increasing amounts of inflexible base load generation, coupled with a rise in variable renewable energy resources and customer-side resources, is forcing utility planners to adapt their objectives and methodologies. Utility resource planning engineers need to supplement traditional production cost modeling tools with tools that reflect changes in net demand for energy and capacity, recognize the value of flexible resources, take into account the flexible capabilities of clean energy resources, and address the uncertainties affecting supply and demand. Mr. Linvill highlights the reliability of low-carbon power systems and offers cost-effective solutions that align regulation, markets, operations, and planning to deliver value and ensure fair compensation.
