Association Webinars: Lowering Emissions by Curtailing Renewables in Power Systems


To lower pollution, it became imperative to integrate as much renewable energies as possible in power systems. This has been translated into forcing the maximum production of variable renewable energy (VRE) ---wind and solar--- into power systems operation. The increasing operational costs to maximize the VRE output became the price to pay in order to lower pollution. However, here we show that it is a misconception that forcing VRE production always lowers pollution. We present some examples illustrating that, apart from increasing costs, forcing VRE production can also increase pollution.


Germán Morales-España received the B.Sc. degree in electrical engineering from the Universidad Industrial de Santander, Colombia, in 2007, the M.Sc. degree from the Delft University of Technology (TUDelft), The Netherlands, in 2010, and the Joint Ph.D. degree from the Universidad Pontificia Comillas, Spain, the Royal Institute of Technology (KTH), Sweden, and TUDelft, The Netherlands, in 2014. Since 2017, he has been with the Energy Transition Studies group at TNO, as a Scientific Researcher. His research interests include planning, operation, economics, and reliability of electric systems and sector coupling.
