Electricity Industry has worked for over 50 years with a set framework of organisation and regulation. The growth till 1990 witnessed a pattern of doubling the capacity in energy decade except in the decade of Nineties. The pace of expansion declined sharply in last ten years. The present status of the Power Sector is far from being satisfactory. Huge transmission and distribution losses coupled with totally improper tariff structure have led to substantial gaps between cost of supply and tariff and much more so between cost of supply and revenue. De-Politiciation of tariff formulation and proper regulation of utilities was considered to be one of the first few essential requirements to set things in order. The Ministry of Power, Government of India has taken a number of important initiatives in the recent past. The Electricity Bill 2001 is perhaps the most important initiative of the Ministry of Power. The steps that have been taken now to bring about reform and restructuring of tariff, removal of imbalances, elimination of gaps between cost of supply and revenue would strengthen the industry commercially and financially.

The term "smart grid" refers to the transformation of the traditional electric power grid into a modern grid. Modernization of the present electric power system is an important step to implement the Smart Grid technology. The structure of the existing power sector in Bangladesh is almost a hundred years old. Due to which the power sector of Bangladesh facing huge power wastage. A Smart Grid also ensures the efficient transmission and distribution of electric power. This paper gives a brief description of Smart Grid, the latest trends, challenges, prospects, cost analysis of smart grid equipment, and its facility. The spotlight of this paper is to implement the Smart Grid's perspective to Bangladesh. That’s included to have new distributed generation technology, smart meter, a pilot project, etc. Also, the main objective of this paper is the comprehensive development of transmission and distribution loss reduction, which will be saving a big amount of capital every year. And that will play a huge role in the economy of Bangladesh to move forward in global progress.

Power supply security tops the agenda of policies, and it is related to restructuring with the intention of improving efficiency. To investigate relationships between restructuring and reliability in the electricity industry of 15 OECD countries from 1987 to 2013, reliability is measured by the index of the sub-sectors (resources, generation, transmission and distribution, and electricity import), and the effects of the forms of liberalized restructuring—entry, privatization, and vertical divestiture—on sub-sectors are evaluated with the random-effect model. Results indicate that restructuring has a partially negative relationship with reliability, but the effect differs by the type of liberalization and supply sub-sectors.

Power sector is considered a key segment for accelerating economic and social growth in India. It has registered significant growth in recent past and has potential to transform the economy. An uninterrupted and quality power supply is the need of the hour. Amongst the three major channels of power sector i.e. generation, transmission and distribution, the distribution Sector has direct interface with the end consumers and is accountable for consumer satisfaction and also for flow of revenues in the entire value chain of Power Sector. Thus, distribution Sector plays a vital role in sustenance as well as growth. But in present scenario is plagued by poor financial health, imbalance in demand and supply, heavy transmission and distribution losses, poor billing and collection and operational and cost inefficiencies. Also consumers also faces problems like high frequency of power cuts, low and fluctuating voltage, lack of responsiveness of service providers and inadequate grievance redressal mechanism. Thus the major concern for power sector is the declining efficiency of the distribution sector and therefore a real challenge today lies in efficient management of the distribution entities. In order to bring improvements in power distribution sector, government has initiated several plans. Reforms have been under way in the power sector for making it efficient and more competitive. Formulation of integrated rating methodology is one major step to bring improvements in the performance of distribution utilities and a tool for quality assessment

In this paper, a discussion has been made about the current contemporary issues and challenges of the power sector in Haryana. The issues related to tariff rates, transmission and distribution losses, financial constraints & NPA, capacity constraints, and aggregate technical and commercial losses are discussed. The Haryana Power Utilities (HPUs) are required to be changed adequately from substantial losses to the sound profits by taking legitimate activities for improving the financial efficiencies, and technical performance.

Transformer failure is a major problem confronting the Nigerian power sector, hindering the transmission and distribution of electric power to various households, institutions, and industries. Many of these transformer developed problem due to the old age of the transformers, overloading, in-availability of technical expertise, poor maintenance culture, manufacturer's faults, just to mention few. The present research focuses on providing half exponential power model for the failure of already installed transformers, with respect to years of installation up to the time of the first failure, using secondary data from the south western part of Nigeria as a case study. The results obtained showed that half exponential power performed better in modeling the first time failure of power transformers. This was possible because of the present of shape parameter which gives flexibility to half exponential power when compared with a half normal distribution.

This paper is based on a research study which was carried out, to empirically assess the impact of power sector reforms, comprising privatization, competition and regulatory reforms in 29 African countries, for the period 1988–2005. The list of countries in the research sample is shown in Appendix 1. The main findings for the generation sector is that, in Africa, though energy sector regulation backed by sector law can bring about favorable outcomes, better results are likely to be achieved if the regulatory agency has been in existence for at least 3 years, and it co-exists with either competition ‘for’ the market or private sector participation. On private sector participation, the presence of Independent Power Producers, management contracts and private shareholding in generation assets, can enhance generation sector performance. The results on the transmission system seem to indicate that though the establishment of a regulatory agency can reduce transmission system loss level, this outcome is likely to be achieved if the regulatory agency has been existence for at least 3 years. On distribution system loss, it emerged that the sole existence of a regulatory agency may not be enough to influence a downward trend in distribution system loss level, unless the market, permits the co-existence of competition ‘for’ the market, with a regulatory agency.

Constant power supply is the hallmark of a devel-oped economy. Any nation whose energy need is epileptic in supply, prolongs her development and risks losing potential investors. Nigeria, a country of over 120 million people, has for the past 33 years of establishment of the National Electric Power Authority (NEPA) agency empowered with the elec-tricity generation, transmission and distribution, wit-nessed frequent and persistent outages. Presently, the federal government has embarked on power sector reforms with the intention of improving the above unpalatable scenario and in turn reduce the scope of monopoly control of the nation’s power industry. This paper therefore looks at the overall power sector reforms as well as evaluates the opportunities and challenges there from; while advocating introduction of a demand side manage-ment (DSM) program by Power Holding Company of Nigeria (PHCN) as a way of reducing energy con-sumption among customers with emphasis on ener-gy conservation, energy efficiency and load man-agement.

Power sector subsidies constituted 83 percent of the federal government’s total subsidies of PRs 558 billion in 2012. The tariff differential subsidy (TDS) amounted to PRs 464 billion (including arrears of PRs 312.8 billion from previous years). The TDS is provided to distribution companies (DISCOs) to cover the difference between the tariff schedules approved by the National Electric Power Regulatory Authority (NEPRA) (which can differ across DISCOs) and the uniform tariff schedule (by consumer group) notified by the Ministry of Water and Power (MoWP) for all regions of the country. The NEPRA-approved tariff takes account of DISCOs’ revenue requirements and various elements of cost. In calculating the average tariff, NEPRA also takes into account companies’ transmission and distribution (T&D) losses. Both revenue requirements and T&D losses differ across DISCOs, which are duly reflected in NEPRA-approved tariffs. The fact that NEPRA approves different tariffs across DISCOs while the MoWP sets uniform tariffs (by consumer group) implies that each DISCO receives a different TDS from the federal government. This translates into different subsidies for each province. By aggregating the TDS by consumer group across all DISCOs, we can also calculate the aggregate subsidy by consumer group.
