Identifying and Addressing Drivers and Barriers to Construct Solar Thermal Power Plant in Mongolia Identifying and Addressing Drivers and Barriers to Construct Solar Thermal Power Plant in Mongolia A dissertation submitted to Murdoch University for the degree of Master of Science in Renewable Energy Buyanjargal Ser-Od B.Eng, Mongolian University of Science and Technology School of Engineering and Energy Murdoch University 2013 DECLARATION I declare that this dissertation is a true account of my research undertaken for identifying and addressing drivers and barriers for constructing solar thermal power plant in Gobi region of Mongolia. All extracts of the work of others are appropriately acknowledged. The main content of this work has not been previously submitted for a degree at any tertiary education institution. Buyanjargal Ser-Od Page | ii ABSTRACT Having an adequate energy supply is a crucial issue in encouraging and maintaining the sustainable economic growth of the country. Due to the development of mining activities, the expected electricity demand of the Gobi region of Mongolia is expected to reach 650 MW in 2020. Thus, it will be necessary to construct a number of new power plants in the Gobi region of Mongolia because the current installed capacity cannot meet the current peak load and the amount of electricity imported from Russia is constantly increasing. This dissertation focuses on identifying the feasibility of constructing solar thermal power plants in the Gobi region of Mongolia. Moreover, drivers and barriers for constructing solar thermal power plants and possible mitigation measures are discussed in this thesis. The current situation and future perspectives of Mongolian energy sector, Mongolian renewable energy resources and its applications, and development of solar thermal power technology in the world are studied and reviewed within the scope of work of this thesis. Technical and economic analysis on parabolic trough CSP and central receiver CSP are undertaken using the System Advisor Model software for performing preliminary analysis of varies renewable energy technologies. According to the findings of these studies, a 50 MW parabolic trough CSP with 2 hours of thermal energy storage is considered the most suitable option in Gobi Page | iii region of Mongolia in terms of the maturity and economic characteristics in comparison with other CSP technologies. In order to implement a 50MW parabolic trough CSP in Mongolia, it is necessary to consider drivers and barriers, and mitigation measures for dealing with the barriers. An abundant solar resource in the Gobi region of Mongolia, renewable energy legality and policy, and the necessity of constructing new power plants in the Gobi region are considered as the main drivers. On the other hand, there are barriers for implementing CSP such as high initial capital cost, and the lack of professional workers. However, it is possible to mitigate these barriers by using Clean Development Mechanism funding formulated in the Kyoto Protocol and preparation of professional workers by vocational training offered by TAFE colleges and universities. Moreover, there are also further potential cost reductions in CSP technologies expected through technological and efficiency improvement measures.

  • How to Create Efficient, Reliable and Clean Electricity Markets: a Regulatory Design for Mongolia and Northeast Asia
    MASTER’S THESIS HOW TO CREATE EFFICIENT, RELIABLE AND CLEAN ELECTRICITY MARKETS: A REGULATORY DESIGN FOR MONGOLIA AND NORTHEAST ASIA Working title: Beyond Mining: Barriers to Renewable Energy Investments in Mongolia Paul Maidowski International Relations (B.A.) University of Dresden, 2010 Thesis Advisor: Professor William Moomaw SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE: MASTER OF ARTS IN LAW AND DIPLOMACY THE FLETCHER SCHOOL OF LAW AND DIPLOMACY SEPTEMBER 13, 2012 Version history V 1. Original: September 13, 2012 V 2. Updated: December 7, 2012 V 2.1. Slightly edited: December 8, 2012 Abstract This paper develops a comprehensive proposal for how Mongolia’s domestic power sector could be made more efficient, reliable and sustainable. The analysis is based on inter- views in Ulaanbaatar. It reviews the literature on power sector reforms in small developing countries and regional electricity markets. In a second step, a framework is proposed for a re- gional electricity market between Mongolia, Russia and China. In principle, this framework is applicable also to South Korea and Japan. The findings include that inadequate regulation has contributed to performance prob- lems in every aspect of Mongolia’s power sector, which remains a horizontally integrated monopoly. A lack of generation capacity was ignored for decades; as a result, supply is ex- pected to fall critically short of demand for the coming 3 to 5 years. Mongolia possesses rich coal resources, but water scarcity, harmful emissions, high vulnerability to the effects of cli- mate change, social constraints and the need for economic diversification will limit the future role of conventional technologies.

  • Net Electricity Generation in Mongolia by Fuel Type (Twh)
    Additional information on calculating the conservative emission factor of Mongolia It is concluded that net emission reductions are achieved by applying the following emission factors in Mongolia: An emission factor of 0.797 tCO2/MWh, which is the emission factor of the most efficient coal-fired CHP (Combined Heat and Power) plant in Mongolia, is applied in case the PV system in a proposed project activity is connected to the Mongolian national grid (supplied by the Central Energy System (CES), Western Energy System (WES), Altai-Uliastai Energy System (AUES), Eastern Energy System (EES), and/or Southern Energy Systems (SES)) including internal grid which is not connected to a captive power generator. An emission factor of 0.533 tCO2/MWh, which is the emission factor of the most efficient diesel power generator in the world, is applied in case the PV system in a proposed project activity is connected to internal grid which is connected to both the national grid (CES, WES, AUES, EES, and/or SES) and a captive power generator or in case the PV system in a proposed project activity is connected to an internal grid which is not connected to the national grid. 1. Current status of electricity mix in Mongolia There are five types of fuel used for the national electricity generation: coal (lignite), wind, hydro, diesel, and imported electricity1. The share of the overall electricity generated from 2013 to 2015 by the type of fuel used is shown in Table 1 and Figure 1. The amount of electricity from wind and hydro power plants, regarded as low cost/must run (LCMR) power sources, was 0.11 TWh (2% of total) in 2013, 0.18 TWh (3% of total) in 2014 and 0.22 TWh (4% of total) in 2015.

  • Rural Electrification & Renewable Energy Utilization in Mongolia
    December 2005 Rural electrification & Renewable Energy utilization in Mongolia Rural Electrification & Renewable Energy Utilization in Mongolia Introduction The Government of Mongolia has identified rural development and rural living standards as having a high priority and acknowledged the drawbacks played by a lack of rural electricity access. Background Energy access in rural areas of Mongolia is minimal and delivered services leave much room for improvement. Of the 314 Soum centers, 55% operate diesel generators to satisfy minimal electricity needs: about half do not operate during the summer, continuous operation is carried out by only 13% of the Soum centers during summer and only 34% of the centers during the winter. The remainder operate only at about 2-4 hours per day during the winter. Soum centers are sparsely populated during the summer when herders move to pasture lands, but provide essential services (such as health and education) during the winter when many herders temporarily settle to survive the cold. The systems are owned and operated by the Soum governments and are not financially or operationally sustainable. The main problems are the inability to generate revenues needed to purchase diesel for plant operation and poor institutional capability of operating Soum utilities. The herders have no possibility of getting electricity service other than by an individual supply source. Under such conditions, cost recovery and maintenance of investments in conventional electricity supply infrastructure have proven to be difficult and alternative delivery mechanisms need to be looked at. It is expected that a combination of institutional reforms, establishing public-private partnerships, and the expanded use of renewable energy will greatly improve living conditions of the rural population as well as improve the delivery of rural services.

  • Geothermal Resources in Mongolia and Potential Uses
    GEOTHERMAL TRAINING PROGRAMME Reports 2001 Orkustofnun, Grensásvegur 9, Number 15 IS-108 Reykjavík, Iceland GEOTHERMAL RESOURCES IN MONGOLIA AND POTENTIAL USES Batbayar Tseesuren Renewable Energy Corporation, P.O. Box 479, Ulaanbaatar 210136, MONGOLIA ABSTRACT This paper presents an overview of surveys on geothermal energy that have been made in Mongolia to date and explores possibilities for its use. Mongolia has geothermal resources but geothermal utilization is not widely developed. Hot springs are though used for bathing, health resorts (balneology) and to a small amount for greenhouse heating. The main region of geothermal activity is Khangai, where there are 3 aimag (province) centres and 44 soum (village) centres, with approximately 241,000 people. Most of them are without electricity, using diesel generation in the evenings for 5-6 hours because of high oil costs. Coal and wood are used for heating. Using geothermal energy for heating, electrical generation and industrial purposes are the main incentives for developing a geothermal infrastructure in the rural areas of Mongolia. Bearing in mind that the Mongolian main gross domestic products come from animal husbandry, good possibilities are also to use geothermal energy for wool and cashmere washing and drying. 1. INTRODUCTION Mongolia is situated in the northern part of Central Asia, far from the oceans, on a high plateau surrounded by mountain ridges. The mountainous country’s mean elevation is 1580m above sea level. Mongolia consists of 22 aimags or province (approx. 50,000-110,000 people in each aimag), and each aimag consists of 12-22 soums (each soum or village has approx. 4,000-5,000 people).

  • C. Group C Countries (Armenia, Azerbaijan, Belarus, Kazakhstan, the Kyrgyz Republic, Mongolia, Russia, Tajikistan, Turkmenistan and Uzbekistan)
    C. Group C Countries (Armenia, Azerbaijan, Belarus, Kazakhstan, the Kyrgyz Republic, Mongolia, Russia, Tajikistan, Turkmenistan and Uzbekistan) Referred to herein as Group C, this group is made up of Armenia, Azerbaijan, Belarus, Russia, Mongolia, Kazakhstan, the Kyrgyz Republic, Tajikistan, Turkmenistan and Uzbekistan. It is a complex grouping, made up of countries with widely disparate natural resources, infrastructure, size and economic development. The grouping recognises the historical links between these countries, which all (except from Mongolia) formed part of the former Soviet Union’s integrated power system, and the absence of any overarching treaty that defines a collective framework for the countries, as is the case with Group A and Group B, though again, voluntary and indicative only with respect to the observers in Group B. The individual country profiles provide an understanding of the level of development each energy sector has undergone and needs to undertake. Unlike Groups A and B above, Group C countries have no external pressure towards the modernisation and liberalisation of their energy regulatory sector. It is thus particularly interesting to observe the progress they may have accomplished in this area. The three highest-performing countries in this group – Armenia, Mongolia and Russia – have made significant efforts over the last five to 10 years to reform their energy markets and regulatory frameworks. In the electricity sector Russia is the best-performing country by a considerable margin. In the six lowest-performing countries, the least-developed indicator is the absence (or low level) of a wholesale market, while limited transparency and the absence or limited independence of the regulator are other critical factors.
