1. Introduction and antecedents Article 14(1) of the Energy Efficiency Directive (EED) requires the following: Promotion of efficiency in heating and cooling (1) By 31 December 2015, Member States shall carry out [...] a comprehensive assessment of the potential for the application of high-efficiency cogeneration and efficient district heating and cooling,... The potential for high-efficiency cogeneration is, firstly, the amount of heat that can be produced by high-efficiency cogeneration and, secondly, the quantity of electricity that is cogenerated with this amount of heat. It is possible to determine these only by hydraulically independent district heating system (district heating area) on the basis of the heat demand of currently operational district heating systems converted to average meteorological conditions. The value of the theoretical feasibility potential of efficient district heating can be obtained from duration charts. As an example, the nature (P h,cs =100 MW, P h,hmv =7.7 MW, Q h,k =30 MW) of the baseline (converted to heating season with an average climate) duration chart of a district heating system is illustrated by the following figure: 100 P h,cs 90 MW 80 70 60 50 40 30 Q h,k 20 10 P h,hmv 0 0 1000 2000 3000 4000 5000 6000 7000 8000 9000 h/év where P h,cs is the thermal output fed to the network by heat generator(s) (heat input required by the system) at -13 C, P h,hmv is the heat output required by the system to be fed to an average network outside the heating season, and Q h,k. is a preferred (e.g. cogenerating or renewable) capacity, which is to be primarily utilised. For the determination of the heat output duration chart of district heating systems relating to an average heating period, the distribution function of daily average outside temperatures in the heating season as well as the linear regression relationship between the actual daily heat demand of the system and the daily outside temperature must be known. The latter must be calculated for an entire heating season. The duration chart of outside temperatures shows the number of hours on 183 days (184 days in a leap year), a specific or lower outside temperature occurs during an average heating season. Duration charts depend on graphical location. In Hungary, the table available for the capital can be used with good approximation. (The duration chart is available in tabular form. In the period before the proliferation of personal computers, scientific papers dealt with the determination of approximate closed formulas, but the development of information technology has made them obsolete.) Heat demand outside the heating season was taken into account in this study, with a single average value calculated on the basis of the actual use data made available for the last two years. 6

The existing cogeneration and renewable capacities may be fit into these duration charts made for the individual systems, thereby giving rise to the energy potential that is theoretically usable at present. As can be seen from the table below, 50 % coverage (e.g. implemented from renewable energy) in the above system requires, taking into account an actual availability of 23 %, the installation of nearly 30 % of renewable capacity. Q h,k /P h,cs (%) Proportion of max. cogenerated/renewable heat generation (%) 23 50 30 61 35 69.2 40 76.2 45 82.4 50 87.6 It can be determined from the actual installed capacity data for each district heating system that in the event of the maximum and actual utilisation of existing cogeneration/renewable/waste heat-based generation capacities, to what extent the set of conditions of efficient district heating is met. Furthermore, the required utilisation rate of existing capacities and/or the magnitude and required utilisation rate of new cogeneration/renewable/waste heat-based capacities to be established can be determined, where the criterion of efficient district heating can be met upon the fulfilment of the above conditions. With the appropriate summing up of the data determined for the individual district heating systems, the territorial/regional and national potential is obtained. Consequently, in the 2014 2020 programming period, it will be necessary to change and green the heat generation portfolio (the system integration of mainly mass, thermal, waste and waste heat) and to increase the efficiency of the distribution system, which requires the implementation of a significant number of large-scale projects. This requires the assessment and impact analysis of expected projects and the drawdown of KEHOP funds (capital cost estimates, expected indicators and schedule). On the basis of the specifications, the duration charts associated with the energetically optimal development of the district heating systems of the country that may be characterised with a heat demand over 8 TJ/year were surveyed and presented with the theoretical load distributions between heat source types. The results obtained serve as a basis for the fulfilment of the reporting obligation specified in Article 14 of the EED in the case of Annex VIII to the Directive, point 1(d), (e), (f), (h), (i) and (j). 7

2. Summary results The following summarises the results of our calculations from the available, individually reviewed basic energy data for 194 district heating systems of 93 municipalities in total. For lack of available data, the study did not include district heating systems that may operate in the individual municipalities and meet industrial demand only or in at least 90 % (basically with steam heat carrier). 2.1 Initial data The total heat input required by the existing district heating systems taken into account, determined by calculation 1 (at a daily average design outdoor air temperature of -13 o C), is 3 365 MW, its total heat demand fed to the network, converted to average meteorological conditions, is 31.9 PJ/year, while the amount of heat sold is 28.0 PJ/year (see Figure 1). More than three-quarters (76.4 %) of district heat is used for residential purposes.

As national average, the value of the capital, -13 C, can be used as a good approximation.

The existing renewable-based installed heat generation capacities that may be taken into account for the purposes of efficient district heating rating are illustrated in Figure 2. Based on the figure, it can be established that at present, a total renewable-based heat generation capacity of 454.5 MW 2 is installed in the district heating systems in question, 246.5 MW of which is cogeneration and 208 MW is direct heat generation capacity. About 111.5 MW of renewable-based installed cogeneration 3 electrical capacity is associated with them.

In total, about 1 150 MW of non-renewable-based installed cogeneration electrical capacity is associated with them. 2.2 Reviewed scenarios and results In our calculations, the thermal and primary energy mixes and the amount of cogenerated electricity of four energy scenarios were determined for each district heating system. In the case of the latter 2 Considering the mass capacity in Tatabánya existing and the thermal capacity in Győr non-existing. 3 Therefore, no condensing capacity is included in this. 9

amount, only the electricity fully cogenerated with the useful amount of heat was taken into account. In further calculations, a constant district heating demand in the future was taken as a basis in this paper, i.e. with a somewhat optimistic approach, it was assumed that the sector would be able to offset the heat demand-reducing effect of the upgrading of primary and secondary systems through market expansion; greening the generated heat mix provides a hope to this. The four scenarios reviewed are as follows: (1) The heat generation mix attainable with existing equipment with the actual/real utilisation of cogeneration and renewable-based equipment (labelled Existing actual/r. in the figures) For systems where actual data were available for the typical average value of the heat generation mix and natural gas-based electricity cogeneration in the current legal and economic environment, these values were included. In other systems, the utilisation rate of the natural gas-based cogeneration capacity quantified by the Hungarian Cogeneration Association at 2 000 h/year in the current condition was reckoned with, and 80 % of the demand that may be met at maximum with existing renewable capacities was taken into account. (2) The best heat generation mix attainable with existing equipment from the point of view of the efficient district heating criterion (labelled Existing max. in the figures) In load distribution, renewable capacities are taken into account for base load, and natural gas-based cogeneration capacities are loaded after renewable capacities have been loaded to maximum. (3) The heat generation mix attainable in the event that new renewable-based generation capacities enter 4 (labelled as Theoretical 1 in the figures) The existing cogeneration capacity carries the base load at maximum utilisation rate in the Theoretical 1 mix, if any. Conceivable new types: -mass, -thermal and municipal solid waste (the MSW ). Of the new renewable-based district heat generators, cogeneration was reckoned with only in Debrecen and in the case of the new Waste-to-energy Plant in Budapest. However, only the value calculated for exclusive heat generation 5 was taken into account. For district heat supply systems where the proposed development is already known (e.g. Budapest North Buda), only the planned capacity was reckoned with, even if the heat generation mix required for the efficient district heating rating also would expect/allow a higher capacity. Otherwise, the capacity of the new technology was selected in such a way that the old cogeneration and the new renewable heat generation units jointly ensure the efficient district heating rating under any circumstances. In the case of systems that already meet the efficient district heating 4 No establishment of any new natural gas-based cogeneration capacity in the foreseeable future was reckoned with. 5 According to estimates, the total capital cost of the whole Waste-to-heat Plant 2 (HUHA2) would be HUF 50 to 65 billion depending on the location of installation and the technical solution. 10

rating even now, no new development was envisaged, and the calculation is based on existing capacities (thus, e.g. no further development was reckoned with for Komló, because on the basis of the current mix, the efficient district heating criterion is met). No development projects were reckoned with for 44 small systems, which do not reach an annual heat demand of 8 TJ, i.e. a thermal power demand of 0.7 to 0.8 MW (less than 200 homes), the total heat demand from a network does not even reach 155 TJ/year, which is half per cent of the total heat demand. (4) Heat generation mix attainable in the event of the entry of new renewable-based generation capacities (labelled as Theoretical 2 in the figures) The scenario reckons with the capacities taken into account for the Theoretical 1 mix, but in this case, renewable capacities carry the base load. For currently efficient systems (in which no new heat generation equipment was reckoned with), it is identical with Scenario 2. In Scenarios Theoretical 1 (3) and Theoretical 2 (4), the renewable-based thermal and electrical capacities foreseen to be installed are shown in Figure 3 and Figure 4. According to the figures, the installation of 482 MW of renewable-based thermal capacity and 41.4 MW related cogeneration electrical capacity were foreseen in the reviewed district heating systems. We note that the possible future appearance of any new aid scheme similar to the previous mandatory power purchase scheme was not taken into account for the estimation of the foreseen cogeneration electrical capacities.

In the four outlined scenarios, the distribution of primary energy use for district heat generation and its percentages are shown in Figure 9 and Figure 10, respectively. In the case of cogeneration, the primary energy used for district heat generation was derived in such a way that the primary energy used for cogenerated electricity, calculated with reference efficiency, was deducted from the total primary energy used. Accordingly, the primary energy demand of 16

district heat is lower in the scenarios that assume more cogeneration (this is exactly the energy benefit of cogeneration). 30 000 000 25 000 000 20 000 000 GJ 15 000 000 Nukleáris Tszh Depónia gáz Geotermikus Biomassza Földgáz 10 000 000 5 000 000 0 (1) Reális (2) Meglévő max (3) Elméleti1 (4) Elméleti2 Nukleáris Tszh Depónia gáz Geotermikus Biomassza Földgáz Nuclear MSW Landfill gas Geothermal Biomass Natural gas Figure 9 Primary energy used for district heat generation in the individual scenarios (GJ/a) 17

As already been mentioned, no development was assumed in 44 small systems representing a heat demand of only 155 TJ/year in total fed to the network. One of them, the Nagyatád system, forms part of the 18

134 efficient district heating systems due to its existing thermal heat generation, thus the number of small systems not to be improved is actually 43. The heat demand of the remaining 15 inefficient systems is 834 TJ/year, which is 2.6 % of the total demand. In their case, due to the high (but not sufficiently high) proportion of either the existing cogeneration (gas engine) or renewable capacity, the establishment of only smaller or 0 new capacities was assumed. 2.3 Additional potential In the scenarios outlined above, the new capacities were included in the systems by bearing in mind only the condition that they should possibly meet (with modest reserves) the criterion of efficient district heating. With regard to practical examples of certain existing district heating systems and values determined by estimation, used in technical and energy engineering practice, if the establishment of new capacities at a rate allowing them to approach 50 % of the thermal power demand in the given system were envisaged, it would be conceivable to establish an additional about 110 MW of new renewable heat generation capacity. The amount of heat that can be generated by them is about 1.6 PJ/year. Assuming that mostly mass and to a smaller extent thermal-based capacities are involved, the investment required for this can be estimated at HUF 15 or 16 billion. 2.4 Estimation of cooling potential A few words will be said below also about the potential of district cooling in this paper (which means only heat-driven cooling (trigeneration)). The economic potential of district cooling is currently zero, because only the energy costs of heatdriven cooling clearly exceed the energy cost of cooling energy generated with traditional electricdriven compressor liquid coolers, not to mention capital load differences due to significantly higher capital costs. The theoretical potential for the district cooling of residences can be estimated on the basis of the amount of heat used for heating (15.87 PJ/year), which is sold to the general public. According to the experience from the few completed district cooling projects, compared to heating demand, both the cooling power demand and the cooling energy demand can be approximated at 50 %, thus the theoretical cooling energy potential can be estimated at 25 % of the heating demand, i.e. exactly 4 PJ/year, in the case of the general public. In the case of non-residential users, setting the capacity demand at 80 % and the cooling energy demand at 65 % of the heating demand (5 843 PJ/year), the theoretical cooling energy potential can be estimated at 52 % of the heating demand, i.e. exactly 3 PJ/year. The technical potential of district cooling is lower than this, because for economic and security of supply reasons, it is not warranted to establish heat-driven liquid coolers to meet load demand. The heat-driven liquid cooler capacity installed at half of the cooling capacity demand may provide for meeting 80 % of the cooling energy demand. Therefore, the technical potential can be put at 80 % of the theoretical potential. There is currently no example for the local trigeneration (a cogenerating and heat-driven liquid cooler at the same site ) in domestic district heating systems. Heat-driven ( sorption ) liquid coolers 19

are installed at one consumer of each of the Tiszaújváros, Szentendre and Csepel (Budapest) district heating systems and a few users of the Debrecen district heating systems, but these pieces of equipment do not operate or hardly operate due to a driving energy price that has multiplied compared to the period of installation. Instead, cooling energy is generated with electric-driven machines. 20

Annexes Duration charts for district heating systems that can be characterised by over 8 TJ/year of heat fed to the network according to Scenario Theoretical 2 The diagrams also show a particular theoretical load distribution between heat generators in accordance with the load allocations in Scenario Theoretical 2, taking into account an existing or planned/proposed renewable (mass, thermal energy or municipal solid waste) energy source for base load (shown in green). In the diagrams, the next element in the order of loading is the existing natural gas-based cogeneration capacity (shown in blue), and finally thermal capacities of natural gas fired load boilers are shown in yellow on top. The new renewable capacities were determined in such a way that together with the existing (high-efficiency) cogeneration equipment, the primary energy mixes required for the efficient district heating rating can be met with a modest reserve for the given district heating system. The figures show, under the name of the system as title, the quantities of heat (GJ/year) generated by the above three heat generation groups (renewable, connected, ) in a year with an average climate and their share in the heat generation mix. The quantities from renewable (mass, thermal) heat generation and cogeneration, taken into account in district heat supply, are theoretical maximum values, which may be affected in reality by scheduled and unexpected failures of the specific equipment generating them. If, in municipalities that have several district heating systems in island operation, the strategic connection of the systems is carried out, both the load allocations and the duration charts of thermal power demand themselves may also change. In the capital, nine large district heating systems supply heat to nine district heating areas. Of these, the strategic connection of the North Pest and Újpalota systems has been implemented. The experience of joint operation is continuously evolving; therefore, the two systems were presented in separate heat demand duration charts in this paper. The Kispest-Kőbánya, Csepel-Pesterzsébet and South-Buda Heating Districts are supplied with heat in island operation; therefore, the duration charts are also shown separately. The connection of three systems in the South Budapest area is a task planned for the coming years. The one- or two-line brief remarks to the figures belong to the figure above the text. 21
