Participation in demand response (DR) has been explored for many large energy using assets based on day-ahead markets. However, little is known about the use of multiple energy markets or DR for open canal systems. In this article, we propose the use of multiple flexible energy markets to enable DR for open canal systems in the Netherlands, where many large pumping stations are used for flood mitigation. We observed that the Dutch market is not yet rewarding DR, with relatively low-priced fixed-price contracts. However, when applied to the German market scenario, a cost saving of 13% was found. In conclusion, the method of combining two flexible energy markets seems successful. However, more simulations and research are needed to explore the full potential. ... Read more

The city of Amsterdam, like many cities in the world, faces the problem that because of our changing climate, rainfall events become more intense. Sewers designed to only flood once every 10 years now flood multiple times a year. In an award winning idea, the aptly named brewery Heavenswater, in dutch: “Hemelswater” decided to raise awareness for the growing urban rainwater drainages problems by brewing a beer using rain collected from their roof in stead of from drinking water. In this “what if” research we study the implications of this idea on a large scale. We look into the consequences for the rainwater drainage, but also wastewater, city planning, health care and last but not least: novel economic opportunities. ... Read more
