4 1. INTRODUCTION National policy related to biomass energy is a part of policy for renewable energy resources. The government sees renewable energy as one of the most important longterm sources of primary energy in Slovenia. In this document we would like to describe main actors in field of renewable energy sources especially biomass sector. Beside that, we present (Chapter 3) some recently developed biomass projects, which could be a good example for the future projects.

5 2. LIST OF MARKET ACTORS IN BIOMASS CHP/DHC SECTOR 2.1 State Actors The Ministry of Environment, Spatial Planning and Energy (Ministrstvo za okolje, prostor in energijo - MOP) responsible for energy in general. An Energy Office (headed by a State secretary) responsible for energy supply and demand actions, including preparation of policy instruments and measures. The Agency for Energy Efficiency (unit within the Ministry of Environment, Spatial Planning and Energy) responsible for the implementation of policy instruments. An Environmental Development Fund (established by MOP) responsible for environmental interventions (Soft loans) and implementation of some energy policy actions. The Agency for Efficient Use of Energy (Agencija za učinkovito rabo energije AURE) the Ministry's implementing office for an efficient use of energy and renewable energy use. AURE dispenses the funds allocated to renewable energy sources (RES) and Energy Efficiency actions by public tenders. It is also conducting awareness campaigns. Whereas AURE management prepares the annual budget and action programme, it does not have a broad mandate and general goals. The Minister takes decisions on each on an annual basis. 2.2 Party Actors The Committee for Infrastructure body within the Parliament responsible for energy matters. GLOBE Slovenia an organisation of the members of the Parliament (it is a member of Globe Europe and Globe International). GLOBE has organised several discussions, but GLOBE Slovenia has initiated no lawmaking motions in recent years. 2.3 Environmental protection Groups Slovenski E-Forum (SE-F) a society for energy economics and environment. It is a semi-professional NGO with individual (non-corporate) membership. Its activities address general energy and environmental issues (energy policies, energy efficiency, renewable energy sources, climate change, ). Project work includes climate change awareness programmes (primary and secondary schools). SE-F is a member of several international NGO networks.

6 Zveza društev za biomaso Slovenije (Society for Biomass of Slovenia) its activities are mainly in field of promotion of Biomass use. Slovenski nacionalni komite WEC (SNK-WEC; National committee of the World Energy Council) mostly represent supply side interests. Institutional members are mainly energy supply companies. In recent years ( ) SNK-WEC held several contracts for preparation of an extensive background document for the National Energy Programme. Elektrotehniška zveza Slovenije (ETZS; Professional society of electrical engineers) issues a professional journal and organises topical discussions on electric power sector issues. Zveza strojnih inženirjev Slovenije (ZSIS, Society of mechanical engineers of Slovenia) professional organisation of mechanical engineers. In 2001 and 2002 it held a contract to organise a broad technical (Internet based) discussion on the national energy programme (in preparation). Slovensko društvo za daljinsko energetiko (SDDE, Slovenian society for district heating) two sectors are most active: district heat supply and gas supply. Biomass based heat and CHP suppliers are also present. It holds a successful annual conference. Regular professional meetings, addressing also RES issues, are organised by the Slovensko društvo CIGRE / CIRED (Slovenian chapters of the international societies for transmission and distribution) and by the University of Maribor»Komunalna energetika/power engineering«. 2.4 Economic Actors Power sector companies Holding Slovenskih elektrarn (HSE, Power Plants holding company) Energy service and RES companies Engineering and architect-engineering companies have a full range of technical capabilities. However, they generally do not venture in complex project development. Commercial companies, in most cases single-project companies have completed small district heating systems based on biomass (wood). One company (ELTEC- Mulej, Bled) is established in the market as a developer and biomass district-heating operator.

7 2.4.3 Local energy supply companies Generally, municipalities establish heat supply companies as public service companies. This is an institutional barrier for a more active development of projects that may lie outside the immediate service area. Some municipality owned companies seek new biomass heating projects (e.g. Energetika Ljubljana). The recent privatisation of several municipal/industrial DH companies (e.g. Energetika Ravne now operated by the Slovenian Oil Company Petrol) has brought new actors to the (biomass) district energy market Industrial companies Paper and pulp factories, wood sawmills, wood-parts and furniture companies operate biomass heat and power plants of traditional design (backpressure and/or condensing steam turbines). In a few cases, this potential has been expanded to provide service to the nearby settlements (e.g. Železniki district heating scheme, expanded in 2002) Equipment manufacturers/suppliers There are few companies (e.g. INEA d.o.o., IMP d.d., ) that supply equipment for Cogeneration objects. These companies usually represent foreign manufacturers on Slovenian market Consultants and research Institutions Jožef Stefan Institute (IJS) a multi-department national institute of advanced research and technology. IJS provided some policy studies and background studies for RES support scheme (the feed-in-tariff), CO 2 tax and climate change mitigation strategies. IJS is the national contact point of several European networks, such as OPET (Organisation for promotion of energy technologies); jointly with the Faculty of mechanical engineering in Ljubljana and the Buildings Research centre (Inštitut za gradbeništvo) and ENER (European Network for Energy Economic Research) and interst groups, such as COGEN-Europe. Elektroinštitut»Milan Vidmar«(EIMV, Milan Vidmar electrical institute) consulting and research institute; traditionally the R&D base of the power sector.

8 Several small companies are active in renewable consulting, of which of the longest standing is the agency for Energy Restructing (ApE, a private company), now active in the following areas: wind, biomass, photovoltaics and local energy concepts. The less favourable situation for small-scale energy projects in the market has resulted in a relative weakening of existing consultant companies and an increase in a number of those seeking fortune in new areas.

13 3.3 Landfill gas BARJE 1 Project Name Landfill Gas Barje 2 Project Brief: 2.1 Location Ljubljana, Slovenia 2.2 Technology Concerned kw Landfill gas power installation 2.3 Type of Financing Feed-in tariff The main project goal is to reduce the ecological impact of landfill site or reduction of the emission of methane. The landfill site is under control of the public company Snaga. The landfill gas includes about 50 % of methane and has about 4,5 kwh/nm 3 and it is appropriate to be used for electricity production in gas motors. 2.4 Executive Summary The goal of the project is to install CHP system by gas motors beside other two gas motors with power capacity of 1240 kw, installed on the landfill site Barje. The area of landfill site (old and new) is about 50 ha and its depth is between 10 to 24 m. There are now 200 gas sounds installed to pump out the landfill gas. The power capacity of the new gas motor is 1040 kw and expected electricity production of 4 GWh per year. 3 Case Description OPET CHP/DHC Work Package 3 List of relevant market actors in Biomass CHP/DHC sector and Page 13 of 16

14 Case Study Background Case Study The landfill sites have to pump out landfill gas (methane) and fire it or use for energy purposes. On the landfill site of Ljubljana two gases motors with capacities of 2 x 620 kw have been installed and they are connected to the grid (electricity network). The total electricity production was more than 9 GWh per year. The installation of the third CHP-gas motor with power capacity of 1040 kw will increase the electricity sold to the public network for additional 4 GWh per year. The place of the plants is far from the urban part of city, because the use of heat is limited to heating the business building in the same place. The project has been carried out in September 2002 and finished in February The gas motor with power capacity of 1040 kw was installed in a standard box (container) like the other two. The container contains the gas motor, generator with adequate control panel. Gas motor Jenbacher Power capacity: 1048 kw Technical data Heat capacity: 629 kw Electrical efficiency : 39,9% Landfill gas: about 52 % Methane and 39 % CO 2 The total investment cost is about 1 million Euro. Costs The investment cost includes the investment costs of working out technical documentation, gas motor and generator, electrical installations and works. 5 Lessons Learned The energy exploitation of landfill gas is recommended. The environmental problems of methane emission can be changed in profit. The installation of a mobile (container) unit is a good solution.
