The main source of data for MODVESS

The main source of data for MODVESS was the energy balance of the Republic of CroatiaWhat is energy balance? - Energy statistic of special shape... Time interval is calendar year Multi-year series - trends and changes Basically it is a table Columns are energy forms Rows are the positions in energy flows



Energy forms in the energy balance

Primary energy forms:Anthracite, Hard coal, Brown coal, Lignite, Crude oil, Natural gas, Hydro energy, Fuel wood, Wind energy, Solar energy, Geothermal energy, Biofuels, Biogas, Other solid biomass (Wood pellets, Wood briquettes, Wood cheeps, Wood wastes), Non renewable wastes

Transformed energy forms:Charcoal, Coke, Liquefied petroleum gas, Gasoline, Kerosene, Jet fuel, Diesel fuel, Extralight fuel oil, Low sulphur fuel oil, Standard fuel oil, Naphtha, White spirit, Bitumen, Oils and greases, Paraffin and waxes, Petroleum coke, Ethan, Other non-energy derivatives, Refinery gas, Refinery feedstocks, Refinery Additives, City gas, Electricity, District heat

Losses – in transportation (or transmission) for network energy forms:• electricity (HEP)• natural gas (INA, survey of 40 natural gas supplier companies)• district heat (HEP, survey about 20 district heat supplier companies)Final non energy consumption (INA, CBS survey IND-21/PRODCOM/G and IND-21/REPRO/G, estimates)Final energy consumption (for every sector from different sources)• for final consumption there is a lack of data• there are certain difficulties in the preparation of balance of final energy

consumption• there is a need for improvement of data sources in the futureThe first step for final energy balance is calculation of final energy consumption (for every energy form):Final energy consumption = Total consumption - Total consumption in transformation sector - Energy sector own use - Losses in transport and distributionAll this values we have from previous calculations (from upper part of energy balance)

Iron and steel industry, Chemical industry, Non-ferrous metals industry, Non-metallic minerals industry, Industry of transport equipment, Machinery, Mining and quarrying, Food, beverages and tobacco industry, Paper, pulp and printing industry, Wood Industry, Construction, Textile and Leather Industry, Other Industry (CBS survey IND-21/PRODCOM/G and IND-21/REPRO/G, estimations)Data are in form of 3 tables:• Production• Consumption of raw materials• Energy consumptionIt is relatively complicated to analyze industrial CHP plants, industrial heating plants and energy consumption in all industrial branchesMy suggestion is to redesign and improve the way of energy data collection for the industry in CBS

Very important step in determining the final energy consumption in all other sectors is analysis of energy consumption in industry.From the table ‘’production’’ I use the production of electricity and heat energy in industrial cogeneration plants and production of heat energy in industrial heating plantsConsumption of raw materials table contains data on energy consumption (energy inputs) in industrial cogeneration plants and industrial heating plants.Table of energy consumption provides information on the consumption of all individual energy sources.It is necessary to connect the data from all three tables, carry out an analysis of each industrial cogeneration and each industrial heating plant so that the relations are correctThis analysis is complicated because often the data are missing or energy efficiency of plants is incorrectWhen I carry out all this analysis and adjustment, energy products consumption (from the third table) is added to consumption in the industrial heating plants and to consumption in industrial cogeneration plants - part of the production of steam and hot waterSubtracting the energy of steam and hot water produced in industrial heating plants and cogeneration plants in accordance with the IEA / Eurostat methodThen it is determined the total and the actual energy consumption in the industry divided into industry sectors according to the IEA / Eurostat methodFor other sectors of final consumption I spend analyses that are different for each energy source or characteristic group of energy sources

Final Energy Consumption in Industry by Industrial Sectors

11

For every energy form used for final consumption I use different methods and different sourcesElectricityFor electricity the total final consumption and final consumption in industry is determinedThe rest of the electricity is consumed in transport, households, service sector and agricultureElectricity consumption in households I take from the HEP (National Electricity Company)Transport - electricity is consumed in rail transport in public city transport (for trams) and in pipeline transport - CBSThe rest of consumption is in agriculture and services sector - there is no data for these sectorsAgriculture - in the past (more than 15 years ago) CBS collected the data for legal entities - based on that I estimate consumption todayThe rest of consumption I put in the service sectorIt is necessary to spend surveys of households and to determine the consumption for heating, cooking, water heating, cooling, electrical equipment and for agricultural purposes in rural areas (survey of households is in progress - IPA project)It is necessary to spend surveys of service sector to determine consumption in certain sub sectors, and consumption for heating, cooking, water heating, cooling, electrical appliances (survey of services is in progress - IPA project)Construction (CBS) – improve and clarify data

Natural gasAt the beginning of the year I conduct a survey of all distribution companies for natural gas (about 40 companies)Data from questionnaire: total quantity of natural gas taken from transport network, total delivered quantity, losses in distribution network, quantities delivered to households, industry, service sector, agriculture, transport and heating plantsThere is a direct supply of industry from the transportation network (INA) – it should be adjust data for direct consumption, data from my survey and data from the CBS for industryIn the survey are collected also additional data - the number of consumers, data for heating plants (the number of households and services, the heated area of households and services, heat power of heating plants), gas prices, net calorific value, the length of the pipelines (distribution network)Analysing of all these data determine consumption in all sectors of final consumption, losses in distribution network and consumption in heating plants - other data I use for additional different analysis

District heatStarting values are the total final consumption and final consumption of district heat in industryAt the beginning of the year I conduct a survey of all public heating plants in all bigger towns and a survey of district heat distribution systems in towns Zagreb and OsijekBased on these surveys I define final consumption of district heat in households and in service sectorIt is necessary to adjust district heat consumption in the industry – CBS data and the data from these surveys

Brown coal, lignite, cokeStarting point is the total final consumption and final consumption of industryRest of consumption is in households and in service sector - consumption in households and service sector has a very small share in total final consumption in these sectorsAt the beginning of the year I conduct a survey of coal traders (about 30 surveys)The answer is about 60%Based on the survey I estimate total consumption of brown coal and lignite in households and services sectorConsumption of coke is only in industry and is known from industry analysisSurvey of households and services which are in progress (IPA project) will improve estimates

Fuel wood and renewable energy sources It is known only final consumption in industry (CBS)There are no additional data on the consumption of fuel woodConsumption is estimated on the basis of cuts of wood in forests - these data are from CBSI also make a climatic correction for each reference yearIt is a very rough assessment - on site surveys in some areas (counties) indicate that consumption determined on that way is too lowOther renewable sources have very small shareConsumption of solar energy determined on the basis of installed collectorsConsumption of geothermal energy determined on the basis of deliveries from several geothermal plantsConsumption of wood briquettes, wood pellets and charcoal is determined on the basis of the sspecial pilot survey –CBS and estimationsConsumption of wood waste in industry is known from industry data (CBS data)Surveys of households and services which are in progress (IPA project) will enable the development of a model for determination and calculation the actual consumption of listed renewable energy sources

Petroleum products - motor fuelsMotor fuels include - gasoline, diesel fuel, jet fuel and LPG (heavy fuel oil - very rare for the drive ships)Primary side of energy balance determined the total final consumption of each motor fuelConsumption of LPG is only in road transport - I conduct a survey of all LPG tradersJet fuel is consumed in air traffic - the only supplier is INA - big problem is division on domestic consumption and on international air bunkerGasoline and diesel are consumed for transport, construction and agricultureThere are some data for construction (CBS), but it is not quite clear what the data includeConsumption in agriculture is assessed (based on ‘’blue diesel’’ consumption’’ and level of activity in agriculture) - the rest is consumed in transportationData from the CBS - known consumption in rail, inland sea and river transport and urban public transport - difference to the total consumption for transport is the consumption in road transportConsumption of road transport include - consumption of Croatian vehicles, vehicles in transit through Croatia, Croatian tourist vehicles and cross-border so called ‘’fuel tourism’’Due to lack of knowledge of these factors it is urgently necessary to conduct on site surveys for transport, agriculture and construction, and to develop corresponding models to determine all these values (survey for transport should be started next year – IPA project, beneficiary is CBS)

Other petroleum productsOther petroleum products are LPG, extra light fuel oil, heavy fuel oil and a very small amount of petroleumMajority of consumption is realized in households and services, and only partly in agricultureThere are no sources of data for consumption in these sectorsConsumption in these sectors are assessed on the basis of relations that are valid for natural gas and other energy formsThe estimates of consumption will be improved after the implementation of the survey of energy consumption in households and services, and in the future probably for agriculture

Non-energy petroleum productsThe CBS data for the industry does not have adequate data for non-energy petroleum products consumption (ethane, naphtha, bitumen, white spirit, oil and lubricants, paraffin, waxes ...). These products must be included in the energy balanceIt is necessary to redesign and improve the way of energy data collection for the industry in CBS. It is necessary to define list of energy products which correspond to list of energy products in the energy balanceData collection should be organized on that way all data will be in one place (in one table) - production, raw material consumption and energy consumption for transport and technological purposes

ConclusionExisting system of data collection for final energy consumption should improve and expandRedesign and improve the way of energy data collection for the industry in CBSConduct on site surveys for households and service sector for the determination of total consumption, purposes of energy consumption and energy consumption in the service sub sectors (survey of households and services are in progress - IPA project)Conduct on site surveys and develop a model for the consumption determination of motor fuels for the different purposes in transport sector (transport survey should start next year - IPA project) Conduct surveys for agriculture to determine the energy consumption in this sectorConduct surveys for determine domestic jet fuel consumption and international air bunkerConduct additional research and possibly surveying the construction sector for a more precise determination of energy consumptionDevelop model for connecting consumption of motor fuels in transport, construction and agriculture.Surveys for final energy consumption should be conducted and repeated every five years in order to gain insight in the dynamics of change
