Dr. Aleksander Grochowicz

I'm a postdoctoral researcher at the Technical University of Denmark (DTU), where I combine mathematics, energy systems modelling, and climate science to accelerate Europe's transition to net-zero. My focus: making energy systems resilient to distinct uncertainties—extreme weather, climate variability, and the complex interactions between research, policy, and diverse stakeholder interests.

I completed my PhD at the University of Oslo, working at the intersection of applied mathematics and energy modelling with the Risk and Stochastics section and the Energy Systems Modelling group. My work builds on open-source tools—primarily PyPSA frameworks like PyPSA-Eur (Europe's electricity and sector-coupled systems) and PyPSA-Longyearbyen (Svalbard's energy system).

Much of my research uses near-optimal methods (Modelling to Generate Alternatives, MGA) to explore trade-offs beyond cost minimisation. What if we designed systems that are slightly more expensive but far more resilient to weather extremes? Or more aligned with social acceptance and democratic participation? These questions matter because the energy transition isn't just about finding the cheapest solution—it's about finding solutions that work for people, places, and the planet.

This spring, I'm teaching "Integrated Energy Grids" at DTU—a course on modelling interconnected energy systems across sectors and regions.

I believe in open science, transparent methods, and research that genuinely improves lives—not just optimises spreadsheets. If you're interested in discussing energy system resilience, near-optimal planning, or working together on a thesis or project, feel free to get in touch.
