INTRODUCTION According to Energy Policy of European Union, developed in 2007 and with Energy 2020 document, energy efficiency is one of the central objectives and is a key factor in achieving European long-term energy and climate goals [1], [2]. For achieving 20% primary energy savings in 2020, energy efficiency measures must be taken on the whole energy chain, from energy production, on transmission and distribution sectors to final consumption. Romania’s draft Energy Strategy 2011-2035 highlights the principal objectives of new energy-environment policy [3]: • Security of energy; • Competitiveness; • Sustainable development; • Environmental protection and climate change mitigation; • Attracting capital investment for modernization and development of energy sector. Majority of Romania' urban households are connected to district heating. CHP systems represent attractive, reliable and cost-effective technologies. In Romania, in 2010, total market share of energy produced in cogeneration was 20%, 10% produced in high efficiency cogeneration. A very important European Line for promoting cogeneration in order to increase the energy efficiency and improve the security of energy supply is 2004/8/EC Directive [4]. The implementation of this Directive in Romania is realized by the GD no. 219/2007. This decision establishes the legal framework for the promotion and development of high efficiency cogeneration of heat and electricity, based on useful heat demand and primary energy savings in the energy market [5]. Another government decision, GD no.1215/2009 sets the criteria and necessary conditions for the implementation the support scheme available to producers of heat and electricity using high efficiency CHP.
