Grid managers TenneT, Stedin, Liander, Enexis Group, Rendo, Enduris and Westland Infra are jointly developing the GOPACS energy market platform. It is an important step to reduce capacity shortages, i.e. congestion, in the electricity grid and hence contribute to ensuring the continued reliability as well as affordability of the Dutch electricity grid. Following a pilot in 2018, the first transactions were conducted this year. They were successful in solving congestion issues. The intention is to expand the platform further in 2020 with more trading markets so as to increase the available flexibility. In Stedin's area of operations, commercial growers form the main group of initial customers providing flexibility through GOPACS.
