Applied general equilibrium models for energy studies: a survey

Subhes C. Bhattacharyya

The importance of energy in any economy, developed or underdeveloped, became clear after the first oil shock in 1973. Since then, different studies were carried out to formulate energy policies and to study their impact on the economies. Since energy policy issues are related to various aspects of the economy such as price formation, output determination, income generation and distribution, consumption behaviour, government operation, etc., a coherent and systematic mechanism is required for such analysis. By offering such a framework of analysis, AGE models gained popularity among energy modellers. In the 1980s, the environmental issues have gained importance, and the focus shifted towards curbing and containing emissions of environmentally unfriendly gases resulting from the use of energy, AGE models, because of their capability to capture the complexities of the economy, have found relevance in analysing the economic impacts of controlling pollution and greenhouse gases. This paper surveys the literature on such general equilibrium models as applied to energy studies, and reports their special features, evolution through time as well as their limitations.

A review of energy system models.

Subhes C. Bhattacharyya; Govinda R. Timilsina

Purpose – The purpose of this paper is to provide a comparative overview of existing energy system models to see whether they are suitable for analysing energy, environment and climate change policies of developing countries.Design/methodology/approach – The paper reviews the available literature and follows a systematic comparative approach to achieve its purpose.Findings – The paper finds that the existing energy system models inadequately capture the developing country features and the problem is more pronounced with econometric and optimisation models than with accounting models.Originality/value – Inaccurate representation of energy systems in the models can lead to inaccurate decisions and poor policy prescriptions. Thus, the paper helps policy makers and users to be aware of the possible pitfalls of various energy system models.

Energy demand models for policy formulation : a comparative study of energy demand models

Subhes C. Bhattacharyya; Govinda R. Timilsina

This paper critically reviews existing energy demand forecasting methodologies highlighting the methodological diversities and developments over the past four decades in order to investigate whether the existing energy demand models are appropriate for capturing the specific features of developing countries. The study finds that two types of approaches, econometric and end-use accounting, are used in the existing energy demand models. Although energy demand models have greatly evolved since the early 1970s, key issues such as the poor-rich and urban-rural divides, traditional energy resources, and differentiation between commercial and non-commercial energy commodities are often poorly reflected in these models. While the end-use energy accounting models with detailed sector representations produce more realistic projections compared with the econometric models, they still suffer from huge data deficiencies especially in developing countries. Development and maintenance of more detailed energy databases, further development of models to better reflect developing country context, and institutionalizing the modeling capacity in developing countries are the key requirements for energy demand modeling to deliver richer and more reliable input to policy formulation in developing countries.

An overview of problems and prospects for the Indian power sector

Subhes C. Bhattacharyya

The power sector in India has registered tremendous growth after independence. As in many other developing countries, demand for electricity is outstripping supply, resulting in widespread power shortages. This trend will continue unless options for improvements are implemented.

An estimation of environmental costs of coal-based thermal power generation in India

Subhes C. Bhattacharyya

Assessment of the costs of environmental degradation of energy use is very important for policy analyses on the one hand and the proper management of the environment on the other. In recent years, some attempts have been made in developed countries to estimate certain environmental costs, especially those related to the electricity sector. However, the environmental costs of electricity generation in developing countries can also be quite important. An attempt has been made in this paper to estimate the environmental costs of coal-based thermal power generation in India. It is found that the costs of environmental impacts are small but not insignificant and results are sensitive to assumptions regarding atmospheric conditions and wind speed.

Energy Security Issues

Subhes C. Bhattacharyya

This chapter focuses on the economic issues related to energy security concerns. Issues related to energy security have resurfaced in recent times due to concerns about fossil fuel depletion, threats to infrastructure and possibilities of disruption due to inadequate investments in infrastructure or market manipulation by market players. This has been strengthened by the recent high oil prices as well as periodic supply interruptions in certain parts of the world. This chapter explains the concept, the economic dimension of the problem and discusses the policies that can be taken to improve the situation.

Electrification Experiences from Sub-Saharan Africa

Subhes C. Bhattacharyya

This chapter provides a review of electrification experience from the African continent by focusing on a selected set of country experiences from Sub-Saharan Africa. The review captures the diversity and similarities of approaches adopted by the countries in this continent and contrasts the successful examples of South Africa and Ghana with other Sub-Saharan African cases. The region lags behind significantly in terms of electricity access and unless huge investment is made urgently, the region is unlikely to catch up with the global trend. While strong government commitment, requisite financial support, and organizational and policy competence have produced clear benefits in the successful cases, tentative approaches, weak governance and poor financial support have created the vicious circle of weak outcomes.

Rural electricity tariffs: Case of India

Subhes C. Bhattacharyya

This paper examines the nature of rural electricity tariffs existing in India and finds that in most cases, there is no special treatment of the rural consumers for tariff purposes, except for agricultural use. There is need for distinct rural electricity tariffs to reflect the costs of supply and to account for targeted subsidies for the rural areas. The factors to be considered for setting up distinct rural electricity tariffs are discussed. These include issues related to subsidy and financial viability of rural electricity supply and the constraints for setting distinct rural tariffs in the Indian context. Separate electricity tariffs for the rural areas could be justified on the basis of cost and quality of supply, better accounting of financial resources, and other social parameters. However, information constraints, political acceptability, and regulatory management of such spatial tariffs may be difficult. There is need for a holistic treatment of the issue of rural electrification and electricity tariffs as opposed to the piecemeal approach followed so far.

Poverty Amidst Plenty: Renewable Energy-Based Mini-Grid Electrification in Nepal

Gopal K. Sarangi; Pugazenthi D; Arabinda Mishra; Debajit Palit; V. V. N. Kishore; Subhes C. Bhattacharyya

Providing access to electricity to a large section of rural population in Nepal has traditionally been a challenging exercise. This has been exacerbated by difficult geography, poor-socio-economic profile of rural Nepal and moreover by the on-going energy crisis. This chapter conducts an objective assessment of the renewable energy-based off-grid electricity sector in Nepal, with specific focus on micro-hydro-based mini-grid systems by applying a mixed method research design built on both qualitative and quantitative research techniques. While the country’s experiences of developing micro-hydro- and solar energy-based off-grid interventions are captured by qualitative analysis, a standard techno-economic analysis of a micro-hydro mini-grid project is conducted to explore the possibility of introducing additional productive loads and to examine the cost efficacy of generating energy from micro-hydro vis-a-vis solar. Assessment of off-grid electrification options reveals that despite visible progresses, there still exist multiple roadblocks to scale up. Absence of clearly spelt out policy goals, weak institutional designs, low load factors, and lack of adequate finance and overall regulatory concerns stand as major obstacles for off-grid electricity sector development in the country. In addition, project-specific analysis reveals that solar loses out as a cost-effective option compared to micro-hydro. But optimal use of energy generated from micro-hydro-based mini-grids requires creation of productive applications at the local scale on a sustainable basis.
