Co-operation between the participating countries is governed by an Implementing Agreement. Decisions on the work programme and budget are taken by the Executive Committee, which has representatives from all participating countries. For the meetings of the Executive Committee international organisations in the field of District Heating and Cooling from Europe (Euroheat and Power Unichal) and North America (IDEA) are invited to attend on an observatory basis.
Projects are defined in Annexes to the Agreement. The Operating Agent acts in the interest of all countries and co-ordinates the activities, negotiates contracts etc. within the budget and programme limits decided upon.
