Mounting of direction stabilizer in the wind power plant on the rooftop of the Institute
 
In 2014, a scientific research financed by the state subsidies Research of application and intensification and development possibilities in Lithuania of small-scale wind power plants and solar energy systems was completed. During the implementation of this study, the analysis of technical characteristics and possibilities of development of small-scale wind power plants (WPP) in the country was carried out; efficiency of small-scale WPPs and its dependence on the wind conditions were assessed. The results of the research show that wind power plants with larger relative rotor area can produce up to two times more energy than the standard small WPP; therefore, in the regions with smaller wind resource it is reasonable to build small WPPs with relatively larger rotors.
Based on the analysis of the complex methodology of assessment of technical-economic efficiency applied to small capacity WPP, it was determined that the analyzed small WPP with horizontal axis is about 5.5 times more efficient than the small WPP with vertical axis. The results of investigations of the wind power plant mounted on the rooftop of LEI led to installation of the direction stabilizer, a so called “tail”. Production of electric power was stabilized and the capacity factor of the turbine increased.
A database for the wind speed prediction model was compiled, the accuracy of statistical methods during the forecast of wind speed for 6–48 hours was assessed, the method of artificial neural network was applied for wind speed prediction. The application of neural network has positive impact on error reduction. It was also found that error values depend on the length of time series used for calculations.
During the research of wind conditions, measurements of wind speed and direction were performed in Kaišiadorys and Lazdijai districts; the impact of meteorological conditions, surface roughness and terrain on the operation of wind power plants was analyzed.
Moreover, the efficiency of power production at photovoltaic power stations in various regions of the country was analyzed in the study, the impact of environment air temperature was assessed, feasibility research of production of electric energy at solar power plants not integrated into electric network and hybrid solar-wind power plants was performed.
 
 
 
Production of electric power from various RES in Lithuania in 2014 
 
 
Since 2013, during the research of small wind power plants, a doctoral dissertation Investigation of renewable energy technologies and application in urban environment has been prepared. The research of the forecast methods for the capacity of wind power plants was also conducted for another doctoral dissertation Investigation of the impact of meteorological and topographical conditions on short term wind power prediction.

 Noise measurements conducted nearby 250 kW capacity WPP 
 
 
In 2014, together with other divisions of the Institute, a long-term program project Research of RES application for efficient energy production and environmental impact of institutional scientific research and experimental development (further – R&D) continued. In 2014, the information about small farms, potential for use of low-capacity bioreactors there, their construction, operation principles, and applicability was collected. Technical and economic indicators, installation and mounting costs of bioreactors were assessed. It was determined that for the farms raising up to 20 heads of cattle, 20 m3 bioreactor module is the most suitable. For the farms raising a larger number of cattle heads, it is more efficient to install bioreactors of 50 m3 capacity.
After the research of the wind conditions, it was determined that the mean annual wind shear coefficient in Kaišiadorys district at the height of 30–50 m reaches 1.55. Measurements at a greater height indicate that the wind shear at the height of 80–100 m is by about 20 % smaller. Due to this reason, the rotors of the lower wind power plants experience greater dynamic loads, and this affects the performance indicators of power plants.
The situation of power production from renewable energy sources was overviewed: in 2014, about 12 % of the consumed electric power was produced from RES, and their largest part (44 %) was comprised by the energy produced in WPP parks.
Solving the issues of environmental impact from wind power plants, causing dissatisfaction of the local communities, the research of the noise produced by wind power plants continued in cooperation with the researchers from the department of Physics of the Faculty of Environmental Studies at VMU. A portable noise analyzer 2250 Bruel&Kjaer and special software were used for this research. Noise measurements were performed at the municipalities of Kalvarija and Vilkaviškis districts nearby 250 kW wind power plants at various distances. It was determined that during a quiet sunny day, the level of background environment noise achieves 33–35 dBA, while at a stronger than 10 m/s wind, the level of background environment noise (50–60 dBA) exceeds the permissible noise made by WPP. At the wind of 5–6 m/s, noise level of 45 dBA is exceeded only up to 50 m from the WPP.
 
Participation in international programs
 
COST program
Since March 2014, the researchers of the Laboratory participate in COST activity Wind energy technology reconsideration to enhance the concept of smart cities (WINERCOST). This activity is aimed at collecting and systematizing the information about expertise of European countries in developing wind energy in the urban environment and assessing the potential of application of wind power plants in smart future cities. Technical, economic and social obstacles and the most efficient measures, fostering development of wind power plants in urban built environment are analyzed. During implementation of this activity, work group meetings, international conferences take place, and summer camps are organized for specialists of various levels.
 
Scientific applied research

 
In 2014, cooperation with business companies continued: the researchers of the Laboratory conducted applied research for six projects, financed by the Agency for Science, Innovation and Technology (MITA) under support means “Innovation vouchers.” During the projects, the analysis of efficiency and aspects of environmental impact of small-scale wind power plants was conducted, noise and shading zones were modeled, the analysis of wind conditions was performed, the perspectives of construction of WPP of various power were assessed, feasibility studies were carried out.

Scientific research carried out in the laboratory  
.
In 2014, a new study Research on efficiency of implemented measures for sustainable energy on the municipal level financed by the state budget was launched. In the first year, the analysis of measures for sustainable energy development and experience, applied methods and criteria, possibilities of their application under existing conditions in Lithuania were researched, based on the analysis of reports on implemented measures; furthermore, a methodological ground for the assessment of these measures was prepared, taking into consideration the strategic goals of the county’s energy sector.
The implementation of this study is aimed at systematization and generalization of the legal framework provisions (Heat, RES, Territorial planning, Renovation of blocks of flats and other laws), allowing and binding municipalities to participate in the development of RES and lead to a wider uptake of the RES technologies and potentials. Economic, financial and legal preconditions for increase of RES and energy efficiency on the municipal level were analyzed and summarized.
 
Long-term institutional scientific research program Economic and sustainability analysis of energy sector development.
The first task of the program is to develop a theory for harmonious energy progress based on sustainable development and knowledge-based interfaces of economy concepts.
In 2014, investigations were performed in two directions for the solution of this task: 1) Analysis of economic preconditions for development of advanced energy technologies in the country and 2) Analysis of Lithuanian education system in terms of formation of mentality of sustainable development and its comparison to the experience of the most advanced foreign countries.

Participation in international projects
 
New Business Opportunities for Solar District Heating and Cooling
.
A 36-month duration project New Business Opportunities for Solar District Heating and Cooling (SDHplus) continued in 2014. The project is coordinated by the partners from Germany Research Institute for Solar and Sustainable Thermal Energy Systems, SFZ Solites. The project involves 18 partners from 12 EU member states. SDHplus project is aimed at a wider integration of solar plants in district heating networks and meeting heating needs in buildings.
The objectives of SDHplus project are to foster a wider application of solar energy in district heating systems by describing and promoting successful examples of solar energy integration into district heating systems; developing and implementing new pilot business models, taking into consideration the fact that the use of RES in buildings is assigned to measures for increasing energy efficiency, also developing and implementing new market strategies for solar energy in district heating sector (e.g., the green tariff, purchasing models).
It is estimated that the activities of the project will help to develop new business models and market strategies, will provide new opportunities for heat suppliers and other market stakeholders, and will directly contribute to the growth of market for solar district heating supply (SDH). During preparation of pilot projects, possible hindrances will be determined (combined operation of solar collectors and cogeneration, high costs, etc.). According to the assessment of European experts, the power of solar heat plants in new EU member states might reach 500 MW by 2020.
Information dissemination, international SDH seminars, and visits of participants of district heating markets to the existing SDH plants are of great importance. In 2013, two meetings of project participants were held. In April, a conference, dedicated to technical decisions of solar DH systems and discussion of city planning and business models, took place in Malmö, Sweden.
 
 
Solar heat collectors in Graz City, Austria
 
The second meeting of the project partners took place in the city of Graz in Austria, where mounted 1 MW power solar collectors directly supply heat to district heating system. Generally, decentralized solar heat supply of the city DH is handled by energy service companies (ESCO).
Integration of solar thermal collectors systems into a large city’s district heating system is innovative, and currently, it is not the cheapest way to produce heat by applying the existing infrastructure. In Hamburg City district heating system, solar thermal collectors with seasonal heat storage produce only 3 percent of the annual heat production. The investments of the project amounted to €22 million, which was financed by the EU and private funds.
 
In June 2014 a symbiotic approach to the application of systems of solar thermal collectors in combination with cogeneration or operation of wind power plants, taking into account the change of electricity prices in the market, was presented at the project meeting and at the conference in Hamburg. Moreover, the reasons for difficult development of the idea of green settlements even in West European countries with a high standard of living were assessed and discussed.
 
In the final year, the project focused on Lithuania, where climatic possibilities for the use of solar heat are practically the same as in Germany, Denmark or Sweden. Several Lithuanian DH companies have already installed solar collectors; their produced heat is used for preparation of hot water for companies’ needs. The first project has been implemented in Dūkštas DH system, when the sun generated heat is supplied to the town heat supply system. Project participants have visited Dūkštas boiler house, where they have inspected the installed solar heating system, got acquainted with peculiarities of its functioning, design and operational limitations.
For pilot possibilities calculations of solar energy used for heat production, several small DH systems in Lithuania were selected; they are located in small towns, where the installation of such solar system could be technically and economically reasonable. Primary assessments of the possibilities of Radviliškis and Raseiniai DH systems were elaborated. Based on technical and economic data presented by the companies, also on the Danish experience, a technical-economic analysis of solar heat production and supply was performed there.
 
On November 4, 2014, Lithuanian Energy Institute arranged a seminar-training, where LEI and Danish experts presented the interested heat suppliers, manufacturers and developers of solar collectors, also consultants and experts the experience of various countries in installation of solar heat systems in district solar supply, technical and economic aspects of such systems, first experience in Lithuania, and possibilities of implementation of a greater number of projects.
 
The possibilities of using solar heat in Lithuanian district heat networks were analyzed while implementing the project. The analysis covered 17 DH systems, most of which are in smaller towns. Primary results of the analysis enabled to expect that solar energy systems may be competitive with other ones, for example, biomass technologies in case of relevant financial support. Such systems along with short-term thermal energy storages would allow covering heat demands during summer season and saving significant volumes of biomass and other fuel. The main benefit of solar energy integration into DH systems if compared to individual facilities is scale economy and lower investments due to the fact that there is no need to install regulation and control devices, heat accumulators, pipelines, circulation pumps in each house, issues of overheating of collectors are easier dealt with.

Research on energy production and energy efficiency in Lithuania
 
In 2014, the scientific study Research of application of new generation heat pumps for heat production financed by the state subsidies was completed.
During implementation of the research, statistical data on the existing one-flat (1-2 flats) buildings, multi-flat (3 and more flats) buildings and buildings of other designation in Lithuania were systematized and analysed.
Reduction of energy consumption in buildings and usage of renewable energy sources in the building sector is one of the priority strategic fields of the European Union. In 2010, for implementation of these goals, a new EU Directive 2010/31/ES (PEND) for enhancement of energy efficiency in buildings was approved. By implementation of this directive, the European Commission encourages that all newly built buildings no later than from December 31, 2020 comply or are close to requirements of energy efficiency of passive or zero energy buildings.
This presents an opportunity in the production field for such technologies as heat pumps, thermal energy designated to heat buildings.
The main requirements that have to be met during design of the heating, ventilation, and hot water preparation systems with heat pumps are discussed in this work. A geothermal analysis of heating systems with horizontal and vertical deep-water collectors, as well as building heat supply using heat pump with thermal pole, was performed.
Lithuanian legislation approved in 2009–2013 and foreseeing measures for installation of heat pumps in Lithuania was overviewed. Scarce works designated for monitoring of the performance of heat pumps operating in Lithuania in real conditions were overviewed. A technical-economic feasibility expertise for heat pumps in apartment houses was presented.
Geothermal heating by application of heat pumps for years has been a subject of discussions in Lithuania; it is called the leader in residential heating. The number of such installed heating technologies is increasing in Lithuania. However, one of the factors preventing a more rapid installation of these technologies in Lithuania is a too high heat consumption in buildings, which currently amounts up to 120 kW/m2 per annum in multi-flat buildings, and in one-flat buildings and public designation premises this amount is even higher. At such high heat consumption, for radiator (not floor heating) heating systems in buildings, the option of using heat pumps is not very economically attractive. Starting from 2020, under EU Directive 2010/31/ES (PEND), thermal energy consumption in buildings will be extremely reduced and will not exceed the amount of 15 kWh/m2 per annum.
Under these conditions, heat production by applying heat pumps may become most advanced technology for thermal energy production. This would substantially reduce the use of fossil fuels and the amount of greenhouse gas emissions. During the preparation for this period, it is necessary to develop scientific research, pilot projects, applied research works for the installation of heat pumps in Lithuania. This requires enhancement of knowledge and competence for experts working in the field and educational activities.
The report presents an overview of European Union and Lithuanian legislation, regulating the use of freons, design and manufacture of heating systems with heat pumps, and qualification requirements for the natural and legal persons installing and maintaining these systems. The propagation means for installation of heat pumps in Lithuania are presented.
It is estimated to use the results of the research to renew the National program for enhancement of efficiency of energy consumption, to draft new legislation of the Republic of Lithuania, regulating construction of passive and almost zero energy buildings and thermal energy production for heating of the mentioned buildings, also regulating expansion of heat pumps in Lithuania.
The obtained results were presented at international and national conferences and in scientific journals. Representatives and specialists of the interested residential houses, educational institutions, and other organizations were introduced to the research results. All the above will help to accelerate the development of technological progress in Lithuania.
The results of the research were used in implementation of the projects Public energy alternatives – Strategy for sustainable development as an opportunity for the region development, (BSR Interreg IV B 2007–2013 program) and Increasing transparency of energy service markets (EU Intelligent Energy Europe program).
 
Participation in international programs
 
In 2014, an international project launched in 2013 Increasing transparency of Energy service marketscontinued. The project is implemented based on the EU program Intelligent Energy Europe together with partners from 20 European countries (Czech Republic, United Kingdom, Germany, Slovenia, Sweden, Belgium, Austria, Bulgaria, Italy, the Netherlands, Poland, Portugal, Slovakia, Spain, Greece, Hungary, Denmark, Norway, Latvia, and Lithuania). The duration of the project is three years. Coordinator of the project is Czech Center for Effective Energy Use (SEVEn).
Currently, for financing projects for enhancement of efficiency of EU energy consumption Energy Performance Contracting – EPC model is applied, which enables achieving good energy saving results. The main characteristic of the agreement on efficiency of energy consumption, i.e., agreement between beneficiary and service provider (Energy Service Company, ESCO), is that the service provider ensures (using their financial resources) the saved amount envisioned in the agreement, which will be achieved after installation of energy saving measures at the customer’s place. The beneficiary (customer) pays off the provided services (in full or partially, taking into consideration the bilateral agreement) not at once, but during a certain period (envisioned in the agreement) from the profit, gained for factually saved energy or energy resources.
European Parliament and Committee Directive 2012/27/ES also obliges the application and expansion of this model. This directive envisions the program for common measures aimed at propagation of energy efficiency in the European Union in order to ensure that the goal of 20 % efficiency of energy consumption is achieved by 2020, and the further enhancement of energy efficiency is enabled.
 
Scheme of implementation of the Agreement on energy efficiency 
 
The main objective of the international project Transparense is to collect most comprehensive information on the activity of Energy Service Companies in the EU, to enable the exchange of experience between individual countries on the achievements and challenges of the mentioned companies.
A pilot form of the agreement on energy efficiency was prepared and approved by the Minister of Economy of the Republic of Lithuania by order No. 4-511, on October 27, 2008. The approval of this agreement form was initiated due to requirements of the European Parliament and Committee Directive 2006/32/ES.
 
The main difference between the Agreement on energy efficiency as compared to currently used various forms of agreements is that after signing the mentioned agreement, the provider of the services ensures saving the amount of energy foreseen in the agreement for the receiver of the services, which will be achieved after installation of energy saving measures at the service receiver’s place. If the actual amount of the saved energy is smaller than that envisioned in the agreement, the service provider covers the incurred financial losses. In this way, the service provider (energy service company) takes all the technical and financial risk related to installation of measures for saving energy at the service receiver’s place.
 
 
Moment of training for the basics of application of the ESCO model for the implementation of efficient energy consumption projects 
 
On September 11, 2014, Lithuanian Energy Institute held training for the application of ESCO model for implementation of the projects for enhancement of energy efficiency. The basics of application of Agreements on efficiency of energy consumption, EU documents, promoting the market of energy services in EU countries, projects for enhancement of efficiency of energy consumption, financial frameworks, the strategy for their funding, and other issues were presented during training. Representatives of Ministry of Energy, Energy Agency, Agency for public investment development, Police department, energy service companies, residential houses and other organizations participated in training.
 
During the implementation of the project, a Code of Conduct for Energy Service Companies was drafted. Compliance with this code enhances the transparency of the activity of Energy service companies and ensures the quality of the provided services. The obtained results enrich the knowledge about the activity of Energy service companies and their capabilities in individual EU countries. Main issues analyzed in this project are presented in the scheme.
The results obtained during implementation of the project will enhance the knowledge about activities of companies providing energy services and their capabilities in different EU countries. The results of the project will be continuously presented during training and at various seminars. The experienced EU energy specialists will help to initiate and implement pilot projects in the 20 countries that participate in the project.
 
In 2014, researchers of the Laboratory published four articles in foreign journals, one paper was delivered at a scientific conference in Lithuania; five research papers on dissemination of science were published.
