We are the regional service company for energy and drinking water in Cologne and the Rhineland region around Cologne. Our company can look back over 140 years of history; it came into being in its current form in 2002 from the then Cologne departments of works GEW K鰈n AG and RGW AG. Today, 80 percent of our company is owned by the City of Cologne, with the remaining 20 percent held by RWE Deutschland AG.
