Denmark has more than 60 years of experience in the exploitation of waste energy from electric power production. The oil crises in th 70`s and the energy policies adopted as a result thereof tuther underlined the energy conservation potential of combined heat and power production (CHP). Also and more recently, growing concerns for the environment favour the use of CHP as one efficient means of reducing noxious emissions into the atmosphere. The use of Danish North Sea gas is another such means and combination of CHP and natural gas could become important in the future. It is established policy that to the extent possible all future electric production plants must be based con CHP, and the existing systems are being expanded considerably, in part through the creation of large new heat trasmission systems. The development of CHP in Denmark has been greatly enhanced by the existence of a large number of district heating systems (DH) established in the late 50's and early 60's. By the year 2000 more than half of the national net heat demand will be met by DH and about two thirds hereof will be based on CHP. Over a 15 year period ending in 200 more than 3.5 billion US dollar will be invested in CHP systems in Denmark. Previous experience shows pay-back periods for CHP projects of the order of 15-20 years and life expectancies more than double of that. Long term loan facilities allow a levelling of the fixed costs over long periods of time. This enables the consumers to obtain an immediate advantage from the savings in fuel and constitutes an incentive towards voluntary use of the CHP/DH systems...Ver documento. INTRODUCTION.
