Turkey's natural gas necessity,consumption and future perspectives

Turkey is an important candidate to be the “energy corridor” in the transmission of the abundant oil and natural gas resources of the Middle East and Middle Asia countries to the Western market. Furthermore, Turkey is planning to increase its oil and gas pipeline infrastructure to accommodate its increased energy consumption. Naturally, Turkish natural gas usage is projected to increase remarkably in coming years, with the prime consumers, expected to be industry and power plants. Energy demand of Turkey is growing by 8% annually, one of the highest rates in the world. In addition, natural gas consumption is the fastest growing primary energy source in Turkey. Gas sales started at 0.5 bcm (billion cubic meters), in 1987 and reached approximately 22 bcm in 2003. This article deals with energy policies and natural gas consumption of Turkey. Besides modernization of present lines and realization of capacity increase, new lines will also be needed. In this context, Turkey, due to its geographical location is, in an important position to vary European supply. Therefore, Turkey's role as a transitory area gains importance.     

Electricity demand analysis using cointegration and ARIMA modelling: A case study of Turkey

In the early 2000s, the Republic of Turkey has initiated an ambitious reform program in her electricity market, which requires privatization, liberalization as well as a radical restructuring. The most controversial reason behind, or justification for, recent reforms has been the rapid electricity demand growth; that is to say, the whole reform process has been a part of the endeavors to avoid the so-called “energy crisis”. Using cointegration analysis and autoregressive integrated moving average (ARIMA) modelling, the present article focuses on this issue by both providing an electricity demand estimation and forecast, and comparing the results with official projections. The study concludes, first, that consumers’ respond to price and income changes is quite limited and therefore there is a need for economic regulation in Turkish electricity market; and second, that the current official electricity demand projections highly overestimate the electricity demand, which may endanger the development of both a coherent energy policy in general and a healthy electricity market in particular.     

A review of Turkish natural gas distribution market

In Turkey, natural gas consumption started at 0.5 bcm (billion cubic meters) in 1987 and reached approximately 35 bcm in 2007. Turkish natural gas usage is projected to further increase remarkably in coming years. In 2001, a reform process was started to create and strengthen a competitive natural gas market. However, the reform has not worked out as expected so far. The present article discusses the application of auctions in Turkish natural gas distribution zones. After presenting a short summary of current literature, natural gas utilization and recent developments in Turkish natural gas market, we draw attention to our main focus, namely city natural gas tenders. Having described the tenders, we present problems associated with them. In the end, we touch upon some regulatory issues and provide some suggestions for improvement.     

China's natural gas: Resources,production and its impacts

In order to achieve energy consumption targets, and subsequently reduce carbon emissions, China is working on energy strategies and policies aimed at actively increasing the consumption of natural gas—the lowest carbon energy of the fossil fuels, and to enhance the proportion of gas in total primary energy consumption. To do this, it is a necessary prerequisite that China must have access to adequate gas resources and production to meet demand. This paper shows that the availability of domestic gas resources are overestimated by China's authorities due to differences in classification and definitions of gas resources/reserves between China and those accepted internationally. Based on official gas resource figures, China's gas production remains low with respect to the projected demand, and will only be 164.6 bcm in 2020, far lower than the 375 bcm of forecast demand. The gap between gas production and demand will reach 210.4 bcm by 2020. Existing plans for the importation of gas and the development of unconventional gas will not close this gap in the next 10 years, and this situation will therefore present a severe challenge to China's gas security, achievement of targets in improving energy consumption structure and reducing carbon emissions.     

Turkey's natural gas policy

This article deals with natural gas policy of Turkey. Natural gas became important in the 1980s. In recent years, natural gas consumption has become the fastest growing primary energy source in Turkey. Natural gas becomes an increasingly central component of energy consumption in Turkey. Current gas production in Turkey meets 3% of the domestic consumption requirements. Natural gas consumption levels in Turkey have witnessed a dramatic increase, from 4.25 Bcm (billion cubic meters) in 1991 to 21.19 Bcm in 2003. Turkish natural gas is projected to increase dramatically in coming years, with the prime consumers expected to be industry and power plants. Turkey has chosen natural gas as the preferred fuel for the massive amount of new power plant capacity to be added in coming years. Turkey has supplied main natural gas need from Russian Federation; however, Turkmen and Iranian gas represent economically sound alternatives. Turkey is in a strategically advantageous position in terms of its natural gas market. It can import gas from a number of countries and diversify its sources. Turkey's motivation for restructuring its natural gas ownership and markets stems from its desire to fulfill EU accession prerequisites in the energy sector.     

Application of genetic algorithm (GA) technique on demand estimation of fossil fuels in Turkey

The main objective is to investigate Turkey's fossil fuels demand, projection and supplies by using the structure of the Turkish industry and economic conditions. This study develops scenarios to analyze fossil fuels consumption and makes future projections based on a genetic algorithm (GA). The models developed in the nonlinear form are applied to the coal, oil and natural gas demand of Turkey. Genetic algorithm demand estimation models (GA-DEM) are developed to estimate the future coal, oil and natural gas demand values based on population, gross national product, import and export figures. It may be concluded that the proposed models can be used as alternative solutions and estimation techniques for the future fossil fuel utilization values of any country. In the study, coal, oil and natural gas consumption of Turkey are projected. Turkish fossil fuel demand is increased dramatically. Especially, coal, oil and natural gas consumption values are estimated to increase almost 2.82, 1.73 and 4.83 times between 2000 and 2020. In the figures GA-DEM results are compared with World Energy Council Turkish National Committee (WECTNC) projections. The observed results indicate that WECTNC overestimates the fossil fuel consumptions.     

Economic impact of oil price shocks on the Turkish economy in the coming decades: A dynamic CGE analysis

As a small open economy, Turkey depends on both imported oil and natural gas, importing almost two-thirds of its primary energy demand. This paper analyzes the economic effects of oil price shocks for Turkey as a small, open oil- and gas-importing country. To analyze the potential long-term effects of oil price shocks on macroeconomic variables of interest, including GDP, consumer price inflation, indirect tax revenues, trade balance, and carbon emissions, we developed TurGEM-D, a dynamic multisectoral general equilibrium model for the Turkish economy. Using TurGEM-D, we analyzed the impact of oil price shocks under three distinct scenarios: reference, high and low oil prices. The simulation results show that these oil prices have very significant effects on macro indicators and carbon emissions in the Turkish economy.     

The economic effect of efficiency programs on energy consumers and producers

An increase in the efficiency of natural gas fired residential appliances allows users to realize the same level of service, heating water for example, while using less natural gas. In addition to this technological benefit to the residential sector, the reduced demand for natural gas depresses the price of natural gas, resulting in pecuniary gains to other energy consumers and pecuniary losses to energy producers. The question we address in this study is whether purely pecuniary effects, those that follow from the price changes elicited by lower usage of natural gas, should enter the debate concerning the implementation of energy efficiency programs. To that end, we explore the price and social welfare impacts of natural gas energy efficiency standards by evaluating the impacts of a specific efficiency standard using the National Energy Modeling System. Our analysis indicates that purely pecuniary losses to producers are largely offset by pecuniary benefits to consumers. Our analysis also provides useful insight into the sources of these benefits and losses. Although our results are based on a specific model and efficiency standard, we believe that the results generalize to other efficiency programs and would be reproduced using other energy models.     

Analysis of the lithuanian final energy consumption with respect to economic changes

The development of energy consumption in Lithuania is investigated on the basis of realistic economic scenarios. The aim is to provide reasonable projections of final energy consumption for selected demand sectors. The main parameters determining consumption are the gross national product (GNP) and the real price for energy. The influences of price level and economic activity during preceding periods are evaluated by using multiple regressions with a quasi-dynamic model. Insofar as these mechanisms cannot be detected for Lithuania, experiences with other former centrally-planned economies, which have already turned into kinds of market economies, are applied to make realistic projections for the transitory period. The underlying scenarios for the GNP and price developments are taken from official Lithuanian projections, but they have been adjusted to allow for the most recent development. The results of the quasi-dynamic model are compared with the official final energy-demand projections to provide policy advice for a proper restructuring of the energy system.     

Analysis of the Lithuanian final energy consumption using fuzzy sets

In the paper, the development of final energy consumption in Lithuania, on the basis of realistic economic scenarios, is investigated. The main parameters influencing the energy consumption are the gross national product (GNP) and the wholesale price of energy. Owing to the uncertainties in former socialist economies, these parameters are described as ‘fuzzy sets.’ The theory of fuzzy sets is used to study the influences that the prices of preceding periods have on the actual final energy consumption, with a quasidynamic model. In so far as this mechanism cannot be ascertained for Lithuania, experiences with other former centrally planned economies, which have already turned into a kind of market economy, are applied to give realistic projections for the transitory period. The underlying scenarios for the GNP and price developments are taken from official Lithuanian projections. The results of the fuzzy quasidynamic model are compared with the official final energy demand projections, to provide policy advice for a proper restructuring of the energy system.     

World oil prices,precious metal prices and macroeconomy in Turkey

We examine the long- and short-run transmissions of information between the world oil price, Turkish interest rate, Turkish lira–US dollar exchange rate, and domestic spot gold and silver price. We find that the world oil price has no predictive power of the precious metal prices, the interest rate or the exchange rate market in Turkey. The results also show that the Turkish spot precious metals, exchange rate and bond markets do not also provide information that would help improve the forecasts of world oil prices in the long run. The findings suggest that domestic gold is also considered a safe haven in Turkey during devaluation of the Turkish lira, as it is globally. It is interesting to note that there does not seem to be any significant influence of developments in the world oil markets on Turkish markets in the short run either. However, transitory positive initial impacts of innovations in oil prices on gold and silver markets are observed. The short-run price transmissions between the world oil market and the Turkish precious metal markets have implications for policy makers in emerging markets and both local and global investors in the precious metals market and the oil market.     

Analysis of imperfect competition in natural gas supply contracts for electric power generation: A closed-loop approach

The supply of natural gas is generally based on contracts that are signed prior to the use of this fuel for power generation. Scarcity of natural gas in systems where a share of electricity demand is supplied with gas turbines does not necessarily imply demand rationing, because most gas turbines can still operate with diesel when natural gas is not available. However, scarcity conditions can lead to electricity price spikes, with welfare effects for consumers and generation firms. We develop a closed-loop equilibrium model to evaluate if generation firms have incentives to contract or import the socially-optimal volumes of natural gas to generate electricity. We consider a perfectly-competitive electricity market, where all firms act as price-takers in the short term, but assume that only a small number of firms own gas turbines and procure natural gas from, for instance, foreign suppliers in liquefied form. We illustrate an application of our model using a network reduction of the electric power system in Chile, considering two strategic firms that make annual decisions about natural gas imports in discrete quantities. We also assume that strategic firms compete in the electricity market with a set of competitive firms do not make strategic decisions about natural gas imports (i.e., a competitive fringe). Our results indicate that strategic firms could have incentives to sign natural gas contracts for volumes that are much lower than the socially-optimal ones, which leads to supernormal profits for these firms in the electricity market. Yet, this effect is rather sensitive to the price of natural gas. A high price of natural gas eliminates the incentives of generation firms to exercise market power through natural gas contracts.     

The reform in the Turkish natural gas market: A critical evaluation

Turkey is in a strategically advantageous position in terms of its natural gas market. Being in the middle of Europe and energy-rich countries of Central Asia, it can be an energy corridor between these two regions. It can import gas from a number of countries and diversify its sources. This situation may also provide motivation for a competitive gas market. The recent reform in the market, which began in 2001, was an attempt to strengthen the natural gas market to this end. However, the reform has not worked out as expected so far. This article discusses recent restructuring efforts in the Turkish natural gas market. We focus on the legal structure and economic consequences of the legal change within the international economic relations. After presenting a detailed discussion of the legal framework, we draw attention to the problems of the industry and difficulties in the transition to a more competitive market structure. In the end, we touch upon some regulatory issues and potential conflicts.     

Industrial electricity demand for Turkey: A structural time series analysis

This research investigates the relationship between Turkish industrial electricity consumption, industrial value added and electricity prices in order to forecast future Turkish industrial electricity demand. To achieve this, an industrial electricity demand function for Turkey is estimated by applying the structural time series technique to annual data over the period 1960 to 2008. In addition to identifying the size and significance of the price and industrial value added (output) elasticities, this technique also uncovers the electricity Underlying Energy Demand Trend (UEDT) for the Turkish industrial sector and is, as far as is known, the first attempt to do this. The results suggest that output and real electricity prices and a UEDT all have an important role to play in driving Turkish industrial electricity demand. Consequently, they should all be incorporated when modelling Turkish industrial electricity demand and the estimated UEDT should arguably be considered in future energy policy decisions concerning the Turkish electricity industry. The output and price elasticities are estimated to be 0.15 and − 0.16 respectively, with an increasing (but at a decreasing rate) UEDT and based on the estimated equation, and different forecast assumptions, it is predicted that Turkish industrial electricity demand will be somewhere between 97 and 148 TWh by 2020.     

Vision 2023: Feasibility analysis of Turkey's renewable energy projection

Electricity consumption of Turkey at the year 2023 is estimated to be around 530,000 GWh. Turkey plans to supply 30% or 160,000 GWh of this demand from renewable energy sources according to the recently avowed government agenda Vision 2023. However, the current installed renewable energy capacity is around 60,000 GWh. Detailed literature analysis showed that only wind and solar energy potential in Turkey can solely supply this demand. In this study, two different scenarios were generated to analyse the cost and environmental impacts of supplying this demand. Scenario 1, which is derived from the official Vision 2023 targets, suggests supplying this demand from wind, solar, geothermal energy and hydropower. The total projected cost based on Scenario 1 is estimated to be $31.000 billion and annual greenhouse gas emissions of 1.05 million tonnes of CO₂ equivalent. According to Scenario 2 or the contrary setup it is assumed that the required demand gap could not be supplied from new renewable energy investments but equally from coal and natural gas. The projected cost is estimated to be around $8.000 billion and annual greenhouse gas emissions at appalling 71.30 million tonnes of CO₂ equivalent. Assuming carbon tax at the year 2023 to be $50 per tonne of CO₂ emitted, supplying the demand from renewable energy sources according to Scenario 1 would generate savings worth nearly $2.175 billion from environmental taxes annually. Thus, making the payback time of the renewable energy investments less than 15 years.     

Gas-on-gas competition in Shanghai

In common with other major economic centres in China, Shanghai's energy consumption has been increasing rapidly to support the high growth rate of its economy. To achieve rational, efficient and clean use of energy, together with improved environmental quality within the city, the Shanghai municipal government has decided to expand the supply and utilization of natural gas. Shanghai plans to increase the share of natural gas in its primary energy mix to 7 per cent by 2010, up from 3 per cent in 2005. This increase in natural gas demand has to be matched with a corresponding increase in supply. To date, the Shanghai region has relied on offshore extracted natural gas but this supply is limited due to the size of the reserves. Since 2005, the West–East pipeline has provided an alternative for Shanghai but demands from other regions could reduce the potential for expanding supplies from that source. Since domestic production will not be sufficient to meet demand in the near future, Shanghai is building a liquefied natural gas (LNG) regasification terminal at the Yangshan deep-water port that would allow an additional supply of more than 3 billion cubic meters per year of natural gas. Malaysia has already committed to supply LNG to the Shanghai terminal at a price that is significantly higher than the wholesale “city-gate” price for natural gas transported via pipeline, but still lower than the gas price to end-use consumers. The presence of both an LNG terminal and a transmission pipeline that connects Shanghai to domestic gas-producing regions will create gas-on-gas competition. This study assesses the benefits of introducing such competition to one of China's most advanced cities under various scenarios for demand growth. In this paper, the impact of imported LNG on market concentration in Shanghai's gas market will be analysed using the Herfindahl–Hirschmann index (HHI) and the residual supply index (RSI). Our results show that Shanghai remains a supply-constrained gas market that will continue to rely upon gas supplies from the western provinces and imported LNG. After 2017, the gas market in Shanghai can be regarded as unconcentrated since its HHI fall below 1800 under a very high growth scenario. In terms of RSI, the gas market can be considered competitive at low, moderate and high growth consumption between 2012 and 2015.     

Natural gas demand by agriculture in the USA

This study sets out to determine whether agricultural consumers of natural gas are responsive to changes in the relative prices of different types of energy. A demand model is specified and estimated. The conclusions strongly suggest that not only is the price of natural gas a factor having an impact on the quantity of natural gas demanded by agriculture, but that other types of energy are substitutes for natural gas and that income and weather (measured by heating degree days) likewise affect natural gas demand.     

Implied elasticities in some UK energy projections

This paper presents some estimates of price and income elasticities for the demand for total delivered energy to final users in the UK. It compares these with the elasticities implicit in three energy projections for the UK and finds that the implicit elasticities in official projections are not obviously consistent with recent experience, while the price elasticity implicit in an unofficial (low-energy) projection is not obviously implausible. These tentative, but important, conclusions are not in any way weakened by looking at other estimates.     

Assessment of demand for natural gas from the electricity sector in India

Electricity sector is among the key users of natural gas. The sustained electricity deficit and environment policies have added to an already rising demand for gas. This paper tries to understand gas demand in future from electricity sector. This paper models the future demand for gas in India from the electricity sector under alternative scenarios for the period 2005–2025, using bottom-up ANSWER MARKAL model. The scenarios are differentiated by alternate economic growth projections and policies related to coal reforms, infrastructure choices and local environment. The results across scenarios show that gas competes with coal as a base-load option if price difference is below US $ 4 per MBtu. At higher price difference gas penetrates only the peak power market. Gas demand is lower in the high economic growth scenario, since electricity sector is more flexible in substitution of primary energy. Gas demand reduces also in cases when coal supply curve shifts rightwards such as under coal reforms and coal-by-wire scenarios. Local environmental (SO₂ emissions) control promotes end of pipe solutions flue gas de-sulfurisation (FGD) initially, though in the longer term mitigation happens by fuel substitution (coal by gas) and introduction of clean coal technologies integrated gasification combined cycle (IGCC).     

Assessing of energy policies based on Turkish agriculture:: current status and some implications

In this study, the current energy status of Turkey and the effects of national energy policies on Turkish agricultural support policies are discussed for both current and future requirements. Turkey is an energy-importing country producing 30 mtoe (million tons of oil equivalent) energy but consuming 80 mtoe. The energy import ratio of Turkey is 65–70% and the majority of this import is based on petroleum and natural gas. Furthermore, while world energy demand increases by 1.8% annually, Turkey’s energy demand increases by about 8%. Although energy consumption in agriculture is much lower than the other sectors in Turkey, energy use as both input and output of agricultural sector is a very important issue due to its large agricultural potential and rural area. Total agricultural land area is 27.8 million hectares and about 66.5% of this area is devoted for cereal production. On the other hand, Turkey has over 4 million agricultural farm holdings of which 70–75% is engaged in cereal production. Machinery expenses, mainly diesel, constitute 30–50% of total variable expenses in cereal production costs. It is observed that energy policies pursued in agriculture have been directly affected by diesel prices in Turkey. Therefore, support policy tools for using diesel and electricity in agriculture are being pursued by the Turkish government.
