1 Objectives and scope of the GBE Factory project Green-Blue-Energy Factory (GBE Factory) - co-financed by the Intelligent Energy Europe Programme, supported by the European Commission. The project promotes the concept of “GREEN-BLUE-ENERGY FACTORY”: industrial and commercial buildings equipped with single or combined renewable energy sources, able to provide electricity, heating and cooling for the air conditioning of premises, as well as for the business activities housed therein. A GBE Factory can be a single industrial or commercial building working with “zero carbon emissions”, or one or more buildings equipped with plants producing renewable energy, which can be distributed to the surrounding companies of the same industrial or commercial area. The project’s main partners are public bodies, organizations and ESCOs coming from the EU (Italy, Germany, Austria, Slovakia and Bulgaria). RE sources that the project intends to consider in GBE FACTORIES will generally be represented by: Photovoltaic on building: kWel Solar thermal on building: kWth Hybrid integrated systems (PH + ST): kWel + kWth Biomass Generators a. Generators PPO - SVO: kWel + kWth b. Plant biomass generators: kWel + kWth c. Biomass from waste generators: kWel + kWth Wind turbines: kWel Geothermal systems: kWth Other: KWel + kWth
2 Objective of the market analysis Main goals and tasks of the market analysis: To assess the needs and preconditions for the establishment and dissemination of green-blue enterprises and of the preparedness to develop this process in Bulgaria – at least in one region and two sectors Direct involvement of at least 70 SMEs/companies in the partner countries (7 companies for each of the 2 sectors focus groups GBE FACTORY projections and market knowledge with special concern to HCIU (heating and cooling intensive use SMEs) Diffusion of projections and market analysis to key actors (300) of the Supply side (Suppliers, developers, engineering organizations, etc.) The market analysis will address sectors with intensive use of energy like: industry: chemical industry, food, textile, metal processing, brick, ceramics, etc. commerce: shopping malls, directional centers, spa, leisure and water parks, etc. others: waste plant, green house, livestock, etc. 3
3 Summarized data of the RES sector’s state in Bulgaria The present survey is not meant to analyze thoroughly the state of the RES sector. Its goal is to present summarized data giving orientation of the situation in Bulgaria in which the project is to be implemented and of choice of fields on which it has to focus. A more detailed description of the state is given in Appendix to the present survey (available only in Bulgarian language upon request).
3.1 National objectives With the Directive 2009/28/ЕC of the European Parliament and of the Council of 23 April 2009 on the promotion of the use of energy from renewable sources, a common framework is being established to encourage the energy of renewable sources and to set mandatory national objectives for the common share of energy of renewable sources in the final gross energy consumption. The mandatory national goal of Bulgaria for the energy of renewable sources in the final gross energy consumption in 2020 is set to 16 %. Based on the requirements of Directive 2009/28/ЕC, the Minister of Economy, Energy and Tourism has drafted a project of a National renewable energy action plan in the Republic of Bulgaria until 2020. The indicative curve to achieve the national target in 2020 includes the following interim indicative targets:
from 2011 to 2012 – 10, 72 %; from 2013 to 2014 – 11, 38 %; from 2015 to 2016 – 12, 37 %; from 2017 to 2018 – 13, 69 %.
3.2 Legal framework and institutions The national policy is set up by the legislative framework and includes the following major legal acts: Energy Act Water Act Protection of Agricultural Land Act Environmental Protection Act Energy Efficiency Act Renewable Energy Sources Act (operative from 03.05.2011) This act stipulates the public relations relevant to the production and consumption of o Electric power, thermal energy and cooling energy of renewable sources; o Gas of renewable sources; o Bio-fuels and renewable energy sources in the transport.
4
Various incentives have been introduced, including preferential prices, priority accession of producers of electric power from renewable energy sources to the electric distribution network and compulsory buy-out of electricity from such sources. Institutions: Council of Ministers: lays down the state policy about the promotion of production and consumption of electric power, thermal energy and cooling energy from renewable sources, production and consumption of gas of renewable sources, as well as of the production and consumption of bio-fuels and renewable energy sources in the transport; Ministers of: economy, energy and tourism, of the environment and waters with responsibilities for the realization of the state policy in the ministries they govern. Sustainable Energy Development Agency (SEDA): has a statute of an executive agency by the Minister of economy, energy and tourism. The executive director of SEDA carries out the state policy about the promotion of production and consumption of electric power, heating energy and cooling energy of renewable sources, production and consumption of gas of renewable sources, as well as of the production and consumption of bio-fuels and renewable energy sources in the transport. The agency comprises four directorates, one of which is the „Renewable energy sources” that participates in the development and updating of National renewable energy action plans (NREAP), organizes the implementation of activities and measures included in the NREAP and other. State Energy and Water Regulatory Commission, which sets preferential prices for buying out electric power of renewable sources, develops methodology of fair distribution between the market and preferential prices of electric power produced by renewable sources between all consumers and other. Regional structures The regional governor: Ensures the state policy putting into practice, coordinates the actions related to the promotion of production and consumption of electric power, thermal energy and cooling energy of renewable sources, production and consumption of gas of renewable sources, as well as of the production and consumption of bio-fuels and renewable energy sources in the transport between the municipalities in the region, etc. The municipal councils adopt long- and short-term programmes to encourage the use of renewable energy sources and bio-fuels. The mayor of a municipality develops and tables for adoption by the municipal council municipal long- and short-term programmes to encourage the use of renewable energy sources and bio-fuels in accordance to the National renewable energy action plan.

The clients of „CEZ Electro Bulgaria” pay also prices for network services, the result of what is that the average prices for the final consumer are within the limits of 0,100-0,110 BGN/kWh. It is evident that the preferential prices for electric energy buy-out from the different types of plants with the use of RES are considerably higher than the electric energy obtained from the final supplier. With the photovoltaic electric stations, they are about 5,5 times higher, and for the wind electric stations – about 1,7 time. With this ratio, the producers’ motivation of these types of RES is to sell the electric energy at preferential prices instead of consuming it in situ or in regions. At the same time, there is a policy of systematic decreasing of the price differences. The Government of Bulgaria declared its vision about the preferential prices decreasing, especially of the energy of photovoltaic and wind electric stations where we observe a process of saturation. The prices of electric energy of RES with the use of grant schemes are decreasing too. Priority attention in the national renewable energy action plan is paid to the use of biomass and thermal energy accumulated by solar collectors.
3.4 Funding opportunities Relatively good opportunities exist in Bulgaria about the funding of RES projects. The credit line along the EBRD on energy efficiency and renewable sources – grant up to 20%; Bulgarian fund of energy efficiency and RES и ВЕИ – preferential rate of interest. Necessity to combine the measures about RES and energy efficiency Credit lines operated by banks (Reiffeisen Bank, ProCredit Bank and other) with grant opportunities up to 15% Programmes under the Operational programme „Development of the competitiveness of the Bulgarian economy 2007-2013” with grant opportunities up to 50% („Green industry” programme for large companies amd “Green economy for SMEs) and priority axis 2.3.2 – improving the energy efficiency and introduction of energy-saving technologies and RES Kozloduy fund, Operational programme for rural development Operational programme „Regional development” 8

ESCO companies, etc.
The availability of opportunities for projects funding and consumption of RES in situ and in regions is a good precondition for the creation and development of green energy enterprises.
3.5 Summary data about the production and use of RES in Bulgaria The Bulgarian economy is among the countries with the highest energy intensity – around 5 times higher than the average for the 27 EU member states.

The examination of the expected benefits and costs of GBE factories is of interest against the background of energy saving activities – it is of very high priority too. The next table shows the summarized results of energy audits accomplished in over 150 industrial companies. It is obvious that the average period of payback for investments of the proposed energy saving measures is around 3,5 years. Simultaneously the RES systems in the industry and he housing stock have a considerably higher payback period – more than 5-6 years. 17

3.6 Conclusions to the RES sector’s state survey:
The accessible potential of all RES in the country is around 6 000 ktoe. The biggest accessible potential of all RES in the country is for the biomass (~2 700 ktoe) followed by the water energy (~2 280 ktoe), the solar energy (~390 ktoe), geothermal energy (~350 ktoe) and the wind energy (~280 ktoe). The average payback period of investments from the proposed energy saving measures is around 3,5 years. At the same time, the RES systems in the industry and the housing stock have a considerably longer period of payback – over 5-6 years.
Sustainable energy development in the conditions of our country including optimal use of conventional fuels may be achieved by combining measures introducing RES with measures improving the energy efficiency.
During the next 10 years, the water energy and the biomass will have the most significant share in the production of electric power from RES, and to meet the needs of heating, cooling and boiler hot water – the biomass and geothermal energy.
Substantial particularity of the RES is the economic expedience for the realization of small investment projects as a consequence of the potential redistribution that necessitates decentralization of the transforming/processing powers.
As a result of the preliminary analysis of the state of the RES sector in Bulgaria the market survey is directed with priority to the following areas:
By types of RES – biomass, solar collectors for heating energy, biogas of recycled waste, thermal sources – with the largest potential Sectors – chemistry, commercial chains, hotels in cross-country section – with significant energy intensity and suitable for the project purposes Regions – national scope and Stara Zagora of broad scope of surveyed entities 18
Results of the market surveys in the following focus groups are shown in the next sections:
Enterprises of the chemical industry distributed across Bulgaria – 40 companies Commercial centers distributed across Bulgaria – 10 centers Entities interested in the use of biofuels – 10 hotels and 10 greenhouses Sites on the territory of the Stara Zagora region Expert assessment – 17 experts Industrial enterprises distributed across Bulgaria – 25 companies

4 Market analysis by focus groups 4.1 Survey of chemical enterprises in Bulgaria The survey goal is to get a representative picture of energy consumption figures and to estimate potentials for GBE F in the sector. The survey is based on the processing of the data of a questionnaire sent out and filled out by the chemical SMEs. Detailed description of the results from the survey is presented in Appendix (available only in Bulgarian language upon request). A total of 42 companies filled out questionnaires have been received. The list of the responding companies and the replies are available in the BIA and confidential. The Report of the survey is structured in three parts according to the structure of the questionnaires. The following conclusions could be made as a result of the survey: General characteristics of respondent companies
The largest group (about 43%) is the group medium sized enterprises. About 45% of all respondents fall in the group of staff of between 50 and 250 employees with an annual turnover below ˆ 50 million. The largest number of respondents is in the sector of rubber industry – about 18%. The largest number of respondents is from the District of Russe– about 14%, followed by the enterprises from District of Stara Zagora – about 11%.
Energy consumption profiles The purpose of this section is to indicate the profile of the energy consumption and the part of heating and cooling from total energy consumption.
All companies use electricity and four of them use electricity only. About 62% use natural gas and about 1/3 use liquid fuels. The largest energy carrier is the electricity (40%), followed by the natural gas (30%).

Only 8 % of the companies have a very advanced level of energy management. The largest is the group of companies aware of energy management (about 45%). The highest is the number of energy efficiency and RES measures implemented for the improvement of thermal insulation (14%), efficient lighting (11%), technology improvements (10,5%) and thermal insulation of buildings (10,5%) – measures of relatively low investments and a short pay-back period. The lowest is the number of co-generation and RES measures (1-2), which require relatively high investments. The highest is the number of the planned measures for implementation of systems of energy monitoring (12%), efficient lighting (12,7%), technology improvements (9,6%) and thermo-insulation of buildings 10,2%), efficient motor control (10,2). There is an increased interest in the cogeneration measures (4,8%) and renewable energy sources (6,6%) which require relatively high investments. In general, the companies with a highest number of implemented measures plan to introduce more measures during the next periods.

Conclusions This survey conducted in chemical SMEs in Bulgaria was quite successful and it has aroused rather high interest among the sector enterprises. Rich information has been gathered and analyzed concerning the SMEs’ state and attitude towards the efficient use of RES.
Data have been used of 42 companies from the chemical industry – small and mediumsized of various subsectors: rubber, pharmaceutics, plastics, paints, organic and inorganic chemicals, polymers and other. The analysis enables assessment of the interest of the sector in the use of RES. Around 11% of the companies are from the region of Stara Zagora, which gives opportunity to project the results of this analysis onto this region.
Around 22% of the companies have considerable energy consumption – over 20% of the overall production costs and the application of RES to cover these costs or part of them would contribute to increasing the share of green energy in the industry of Bulgaria.
Around 40% of the total consumption of energy is electric, and around 14 % of the liquid fuels – energy carrier of high impact on the greenhouse gas emissions. Enterprises using liquid fuels are serious potential candidates for GBE factories leading to improved competitiveness and decreased greenhouse gas emissions.
Heating and domestic hot water in SMEs are used in the range of 38-44% of the total consumption of heat energy – types of consumers with special priority for the GBE Factory project.
Around 24% of the total consumption of electricity is used for heating and cooling – types of consumers with special priority for the GBE Factory project.
Only 2 of the surveyed companies have been using RES as an energy saving measure, resources and environmental impact during the last three years. The assessments of the introduction of RES are positive. Other 7 companies are planning to introduce RES, and 5 – cogeneration systems in the next 2-3 years. This is an indication of the growing interest in the green industry and readiness for long-term oriented investments.
As a whole, the companies evaluate positively the extent of their awareness as well as the services offered by suppliers of RES.
The obstacles mentioned for the implementation of energy efficiency measures relate in practice unambiguously (and in most cases – to the largest extent) also to the use of RES in companies. Among the impediments mostly mentioned is the lack of specific information (technical, expert best practice related, etc). The tasks of the GBE Factory project are meant to surmount these barriers largely.
All companies show interest and willingness to participate in the activities organized under the project.
