RWE is one of the world's largest energy and power companies. Its lignite open pit mines near Cologne, Germany, are very similar to the planned Phulbari Coal Project in terms of geological setting, ground conditions, water management, and environmental and social impact. Their Cologne open pit operations produce 100 Mtpa of lignite which produces 10.9GW of electricity in mine mouth power stations. RWE consulted to the Project on water management. They remain under contract to GCM for review work during the Project implementation..
