Report of the experimentation action of the Energy / Emissions balance in Municipality of Dolni chiflik ERDF3, BSREC 1. National Legislation on energy balance The Bulgarian Government has not accepted a law for obliging the municipalities to have an energy balance. The local authorities' obligation is to prepare an Energy strategy for their territory. This strategy should be based on an energy balance of the Municipality for defining a proper aims, but often it is not prepared with an appropriate study. The balance of this territory is done for the public and residential buildings. For the private sector has been done an estimation of the consumption according to the standards in the national regulation. The transport is not evaluated, because of the lack of data. The main energy sources that have been examined are electricity, liquid fuel and wood. The data has been provided by the municipal administration. It was discussed unofficially to update the balance every 3 years. The study will be used for Covenant of Mayors Baseline Emissions Inventory. It is planned also to implement the recommended Energy Saving Measures. 2. Description of the involved territory The territory of Bulgaria is around 111 000 sq. Km (110 510 sq. km ground surface and 333 sq. km water surface). The population is decreasing in the last years and it counts 7 364 570 people, according to the last census done in February 2011.

Dolni chiflik GENERAL INFORMATION Territory – 487 sq.km. Number of settlements – 17 Number of habitants – 19 354 (01.02.2011); GDP for North-East Region – 7 241 mill. BGN/ year GDP per capita for the region: 7313 BGN/year Administrative centre – Dolni chiflik Address: Dolni chiflik, 1 Ticha Sqr Municipality major – Borislav Natov /2006-2015/. Administration office - 05142 2001 Е-mail: [email protected] Dolni chiflik is located in northeastern Bulgaria and is one of the municipalities of Varna District. It has 17 settlements with total population of 19 360 inhabitants (data from 01.02.2011). The municipality of Dolni chiflik covers nearly 487 square kilometres, which includes Kamchia valley, Longoza, northern slopes of the Kamchia Balkan and Black Seacoast line with its shelf, which is 13% from the territory of Varna District. Tucked far away from large sources of pollution Dolni chiflik is an ecological oasis: clean air, soil, water and comfort, protected from mechanical and technological noises. Dolni chiflik has very rich unspent resources for tourism development – from the traditional seaside holiday tourism to the alternative forms of rural, cognitive, hunting and eco tourism. Dolni chiflik is of medium type, with exceptionally rich biodiversity and climate, combined with good geographical location, but it has always remained in the shadow of the large administrative and industrial centers nearby like Varna, Burgas, Devnya etc. All settlements have access to the municipal center and the city of Varna. The municipality operates the railway network provided by the Railway Division – Division III of the main railway line in the area of Nova Shipka 3,5 km - double, electrified. The municipal infrastructure creates limitations on local businesses, and farmers. The main problems are associated with the transportation of the production and dissemination to the municipal markets and beyond. On the territory of the municipality there are two agricultural cooperatives and 16 private lessees, who together with the High School of Agriculture manage 68,955 ha of agricultural land allocated as follows: permanent crops 9255 acres, including vineyards – 6080 acres; cereals – 47920 acres; oilseeds – 6180 acres; vegetables – 5600 acres. According to Department of Labor Bureau to 30.09.2009 years the unemployment rate compared to the economically active population of Dolni chiflik is 10.77% (30th of Sept. 2009). It is a clear positive trend of reducing the unemployment.

Methodology of data collection and elaboration - Sector selected – public and residential, energy vectors – electricity, liquid fuel and wood - Data sources for each sector and/or vector – The data for the public sector has been provided by the municipality and for the residential sector has been estimated. - Period (which year(s) the data refer to?) – 2008 - 2010 - Main assumptions for the estimation of the consumption of residential sector – o Residential sector (data, taken from the municipality): Buildings Dwellings Total Armoured- Brick Other Total Armoured Brick Other concrete -concrete Dolni chiflik 7125 75 6317 733 8137 302 7059 776 31.12.2007 The residential sector has a bigger share from the buildings in the Municipality. Most of it is consisted of one or two level houses, which are mostly heated by wood. In the buildings with armored concrete often is used also electricity for heating. Useful building surface/ capita -m2 2004 2005 2006 2007 Varna 28.96 29.40 30.04 30.55 District Dolni 22.69 22.74 22.78 23.02 chiflik Source: NSI (National Statistic Institute) The useful building surface is 23.02 m2, the population is 19354, so the building surface is (19354 citizens) x (23.02 useful building surface) = 445529 m2. The energy, used for heating of one and two level houses can be estimated with the following calculation: Width of walls – 38 cm (Version 1) and 25 cm (Version 2) and we assume that they are separated half by half. The reason for making this rude estimation is the lack of statistic about the construction of buildings and especially for the width of the walls. Therefore we separate the two options of wall width constructions by even, because of the lack of more accurate data. On that base of that estimation is the following calculation of annual energy consumption for heating: Version 1: Annual energy consumption = 33.96 MWh or Specific annual energy consumption = 173,89 kWh/m2 Version 2: Annual energy consumption = 38.09 MWh or Specific annual energy consumption = 195,02 kWh/m2 Using that costs, we receive: Annual energy consumption = 0,5х(445529 m2)x(173,89 kWh/m2) + + 0,5х(445529 m2)x(195,02 kWh/m2) = 82 180 052 kWh = 82 180 MWh. It can be accepted that the electricity, used for heating, is not more than 15-20%. For instance with 20% share of electricity, the carbon emissions will be: Carbon emissions = (82 180 000 kWh) х 0,2 х (0,683 kgCO2/kWh) + (82 180 000 kWh) х 0,8 х (0,006 kgCO2/kWh) = 11 225 788 + 394 464 = = 11 620 252 kgCO2 = 11620 t СО2 per year. - Emissions factors chosen and eventually greenhouse gasses other than CO2 (CH4, NOx, etc.) Energy Source Coefficient Energy Emissions % gCO2/kWh kWh t СО2 Electricity 683 659 225 450,25 42,19 Diesel 311 1 964 462 610,95 57,25 Wood 6 1 004 862 6,03 0,56 Total: 1067,23 100 - Organizations and people involved in the data collection and analysis (outside and inside the Municipality – Only one employee of Municipality of Dolni chiflik took part in collection of data – Yordanka Dimova, chief of department "Environment protection projects". The energy balance was prepared by Assoc. Proff. Nikolay Angelov, who has been part of the team, elaborated the energy balances of Dobrich and Varna for Covenant of Mayors initiative. 3.
