Power and Energy Systems
Mission
We converge to conceive, design, research, develop, de-risk and demonstrate the next generation smart grid with the grand objectives of increased resilience, decreased uncertainty and greater sustainability. We integrate our research into the education of the next-generation workforce for the industry. We foster fruitful collaborations with academia, national labs, government agencies and the industry.
