Abstract:
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.

Abstract:
The study examined the productivity in the electricity industry in Nigeria. The aim of the study was to ascertain the determinants of productivity in the electricity sector. The research design adopted for the study was a longitudinal study of productivity in the electricity industry in Nigeria. The study considered time series data for a 20 year period from 1996 to 2015. Data on study variables were obtained from Central Bank of Nigeria (CBN) statistical bulletins, National Bureau of Statistics (NBS) annual publications, and the websites of both Transparency International (TI) and Energy Information Administration (EIA). Based on the study objectives, the fully modified ordinary least square (FM-OLS) technique was used to estimate the multiple regressions between productivity and the explanatory variables. Data analyses were carried out using the software application of E- View 9.0. Results from the study showed that the total factor productivity which is an indication of efficiency in the electricity sector was 0.29. This is low when compared with international best practice of 0.80. Also, results from the study revealed that funding, weather condition, vandalism and labour supply have significant effect on productivity of the electricity industry in Nigeria. However, tariff structure and corruption were not statistically significant in the prediction of productivity in the electricity industry. The study recommended that increased budgetary allocations should be made available to the electricity industry to provide the needed improvements in the sector.

Abstract:
The paper aims to summarize and analyze the statistical data on the generation structure and price behavior in the Russian electric power industry and, based on the analysis, make a statistical contribution to the discussion on the outcomes of the electricity reform in Russia. A brief review of this topic is provided. The study states that the electric power industry should be regarded as a combination of four sub-industries when regulation, market design, and industrial organization problems are discussed. These four sub-industries are generation, transmission, distribution, and sales because of different regulations applied to these businesses. The main trends in the retail price index and some other indexes in the four sub-industries are observed from 2009 to 2018. The trends in electricity consumption and generation structure are discussed as essential components of economic processes in the industry. The findings suggest that the four sub-industries make different contributions to the overall growth of the electricity supply costs for end consumers. Most growth was determined by regulated government-granted monopolies in network businesses (transmission and distribution companies). The sales business is represented in the research by suppliers of last resort.

Abstract:
Currently, the majority of world economies (even those located in the sunbelt (+/− 35 degrees of latitude with good sunshine with low seasonality) uses various types of fossil fuels as the main source of energy for their economies. However, this represents a very volatile and unsustainable strategy, since according to various estimates, the fossil fuel era will inevitably end as all carbon fuels are going to be spent in the next few centuries. Unlike traditional energy, renewable energy sources (RES) are not based on energy resources, but rather rely upon natural energy flows. With regard to its unique property, there has been an active construction of power plants of renewable energy and their gradual integration into national energy supply systems in recent decades. At the same time, the existing models of electricity markets were unprepared for their wide distribution. Hence, determination of the market value of energy generated by power plants using renewable energy sources becomes a particularly significant issue. This market value has to take into account the prevention of costs from the use of fossil fuels, as well as the resulting environmental benefits. Our paper proposes methods for solving this problem, contributing to the increase of economic efficiency of investment projects for the construction of renewable energy facilities and the formation of economic incentives for their propagation in energy supply systems. The proposed methods are based on the dynamic differentiation of tariffs for consumers with renewable energy sources depending on their structure of electricity consumption. Its effectiveness is demonstrated by calculating the cost of electricity for households located in the Krasnodar region using renewable energy sources. It is shown that this approach to the formation of tariffs for consumers allows the household to receive additional savings from the efficient use of energy installations on RES and energy storage devices in terms of alignment of the energy consumption schedule. This creates a significant incentive for households to use them and contributes to increasing the effectiveness of government renewable energy support programs, including by solving the acute problem of raising electricity tariffs from the grid.

Abstract:
The development and implementation of a strategy for organizational reconfiguration of a digital heat and power super system to streamline the processes of providing structured technological zones with heat makes the basis for creating a coordinated system for optimizing the tariff and price load on heat and electricity consumers in the Russian economy. Providing the industry with a mechanism for regulating the processes of rendering heat energy services based on the transition to the system of Unified Heat-Supply Organizations (ETOs) and ensuring a return on price trend investment in the heat market with the possibility of transferring departmental reporting and analytics to a single regulatory legal basis enables regulating the operation of the power system as a subsystem of the Russian energy sector with a common information technology platform. It is proposed to develop a methodology for constructing mathematical estimates of reliability indicators of provided heat and power services in the form of analytical relationships and simulation models, taking into account the complex nature of the operation of electric power transmission and heat transportation networks as well as information systems that provide processing, storage and distribution of digital data and documents. The key activities are: development of a methodology for constructing mathematical estimates of reliability indicators of provided heat and power services in the form of analytical relationships and simulation models; development of digital methods for detecting hazardous effects; development of algorithms for storing information in the presence of natural and artificial interference; development of digital methods for optimization, modernization and transformation of production chains and processes, control models and planning procedures to neutralize threats to the reliability of provided heat and power services. The result should be the creation of a computer-based information system for modeling impacts on the electric and heat grid facilities.

After the introduction of the Energy Law in 1997, many enterprises started to operate in the power industry, which is translated into the electricity prices competitiveness. The further household tariff extension with more expensive rates at peak times, and favorable lower rates during the night and off-peak hours, did not result significantly change among users belonging to the most generic household tariff G11 with a single electricity rate per KWh (Kilowatt hour) regardless time of use. The article analyzes the electricity purchase and supply costs of the largest households group belonging to G11 tariff and simulates the effectiveness of moving from existing tariff group to the offered competitive tariff according to electricity suppliers.

Abstract:
Purpose To promote the development of renewable energy, the Chinese Government adopts the policy of Feed-in Tariff and subsidy. However, the high purchase price and the intermittence limit the development of renewable energy source electricity (RES-E). The purpose of this paper is to discuss the pricing strategy for system operators to stimulate the development of the RES-E industry under the scenario of uncertain supply and demand. Design/methodology/approach The authors establish a two-echelon supply chain investment model led by a power grid operator considering the uncertainties in both demand and supply, and study the impact of the power purchase price designed by a system operator using Stackelberg’s model. Findings There is an optimal capacity for RES-E generators, that is, independent of the market demand. Besides, the optimal order of grid operators is independent of the uncertain RES-E supply and the purchase price of fossil fuel. By properly setting the purchase prices, the system operator can stimulate the capacity investment in renewable energy. Finally, increasing the punishment in power shortage can stimulate the capacity investment in RES-E under certain conditions. Practical implications The result of this paper can mitigate the phenomenon of power abandonment in the RES-E industry and promote the grid integration of RES-E. Originality/value Both uncertain demand and supply are considered in this paper. A heuristic algorithm is provided to compute the optimal purchase price combination.

The existing methods for calculation electricity tariffs for enterprises are analyzed numerically. The efficiency of diesel generators use for power supply was estimated using a real object as an example. A methodology has been developed for choosing the optimal price category, based on the schedule for consumption of electrical energy of a particular enterprise, taking into account introduction of its own generation in the 0.4 kV network. It is shown how to get the maximum benefit using one of the most affordable and autonomous power sources, taking into account the peculiarities of tariff setting for electricity.

Abstract:
Os pólos industriais são uma realidade no Brasil, mas, do ponto de vista da legislação, carecem de um tratamento específico e claro, particularmente com relação ao compartilhamento da infra-estrutura e aquisição de insumos energéticos. A falta de clareza na regulamentação brasileira abre espaço para interpretações divergentes com relação ao suprimento energético, que muitas vezes acaba prejudicando a captura de sinergias e ganhos de escala nos pólos industriais, principalmente para as empresas menores. Este cenário gera incerteza com relação aos preços finais de energia e reduz, de forma artificial, os benefícios inerentes à formação de pólos industriais. A adequação na legislação do setor elétrico brasileiro é fundamental para se criar um ambiente regulatório que defina de forma clara e objetiva soluções para a questão energética nos pólos industriais. Neste trabalho apresentam-se proposições de inovações na legislação do setor elétrico brasileiro que poderiam criar um ambiente regulatório transparente e seguro às empresas, no que se refere ao suprimento elétrico, compartilhamento de infra-estrutura e aquisição de energia elétrica em pólos industriais. As inovações propostas preservam as condições de suprimento elétrico dos pólos existentes e também incentivam a criação de novos pólos.
Industrial cluster systems are a reality in Brazil but Brazilian electric regulation does not have a specific and clear treatment about industrial cluster electric supply, especially regarding infra-structure common usage and group energy purchase. This lack of regulation generates a scenario of uncertainty about the energy costs for companies placed in Industrial cluster systems, and reduce, in an artificial way, the advantages that industrial clusters naturally has. The modification in Brazilian electric regulation is fundamental to define energy policies aspects for industrial clusters, to provide a safe environmental for existents industrial clusters and to generate conditions to create new ones. In this dissertation, innovations in Brazilian electric regulation are presented aiming to create a safe and clear environmental for industrial clusters. The proposed innovations preserve the electric supply conditions for the existents industrial clusters and support the creation of new sites, where two or more industries can share electric infra-structure and purchase energy together.

Abstract:
The global transition towards sustainable, secure, and affordable electricity supply is driving changes in the consumption, production, and transportation of electricity. This chapter provides an overview of three main causes of political–economic tensions with smart grids in the United States, Europe, and China, namely industry structure, regulatory models, and the impact of energy policy. In all cases, the developments are motivated by the possible improvements in reliability and affordability yielded by smart grids, while sustainability of the electricity sector is not a central motivation. A holistic smart grid vision would open up possibilities for better integration of distributed energy resources. The authors recommend that smart grid investments should remain outside of the regulatory framework for utilities and distribution service operators in order to allow for such developments.

Abstract:
Abstract The purpose of this chapter is to investigate the effects of some mainstream policy schemes in the power sector on the reduction of CO2 emissions. The first part of this chapter is the analysis on the effects of promoting generation (fuel) efficiency of fossil-fuel power generation, specifically assuming more efficient coal-fired power plants that recently indicates increased presence in the Japanese power sector. Improvement in generation efficiency of fossil-fuel power plants is expected to reduce emissions of carbon dioxide mainly from a technological aspect. However, overall effects on carbon reduction in the whole industry would be ambiguous since it also depends on market structure. The increased efficiency in generation leads to an improvement in cost conditions of fossil-fuel power producers relative to their rivals. It enables them to expand their generation and market share. Analyzing the Cournot oligopoly model, it is shown that an improvement in fossil-fuel power generations produces two effects: the ‘saving effect’ and the ‘rebound effect’. The total CO2 emission in the whole industry decrease if the former effect exceeds the other, and vice versa. In addition, it is indicated that a rise in the generation efficiency would increase a difficulty of implementing carbon tax. In the second part of this chapter, I study the combination of feed-in tariff and carbon tax; that would be worthy to investigate since they could possibly complement each other. FIT policy could be financed by the revenue of carbon tax, and a reduction in electricity supply by the carbon tax would be lessen by supporting renewable power generations under FIT. It is demonstrated that FIT had the combined effects: it fosters a competitive environment in addition to indirectly reduces CO2 emissions. The result indicates that the combination of these policies would produce potential welfare gains.

Madhya Pradesh is in a low level equilibrium of low quality supply, high loss levels, low collection efficiency, and growing subsidy. This outcome persists despite a reform effort, but one which only consolidated bureaucratic control and introduced a tariff shock without tangible gains to the population. The state has bet on electricity supply as a growth industry, increasing capacity five-fold since 2000, but the resultant overcapacity could further limit room to manoeuvre. The electricity sector continues to be perceived as a political risk, a perception shaped by a post-reform loss by the reforming party, the India National Congress, in 2003.

The Introduction outlines the structure of this VSI, which starts with a review of basic ideas and well-established energy systems before moving on to consider how a future energy system might be configured. Energy systems provide the solid, liquid, and gaseous fuels as well as electricity that we use in buildings, industry, transport, and agriculture. They are essential for modern life, but energy systems are changing at a pace not seen since electricity began to be distributed widely more than 100 years ago. The radical changes in both the supply and use of energy are being driven by the needs of modern society, environmental concerns, and rapid developments in technology.

Abstract:
The state-owned power utility, Eskom, generates about ninety five percent of the electricity produced in South Africa. Plans by the government of South Africa in the mid-nineteen nineties to restructure the electricity industry in the country prevented Eskom from embarking on capacity expansion activities when it was necessary. Load growth, as a result of economic growth and a national electrification programme, caused an erosion of the electricity reserve margin, which was quite massive in the early nineties. The large reserve margin then caused Eskom to reduce operating capacity by mothballing some generating plants and putting them in reserve storage. The current situation is that the reserve margin has dropped to about 17,4 percent and a capacity expansion programme is underway. Though the apparent reserve margin is within the desired range, plant unavailability has diminished the reserve margin in real terms and this does not leave Eskom with much room for planned maintenance and a buffer to manage unplanned maintenance, the result being that plant incidents and technical problems cannot easily be absorbed within the power system to avoid interruption of supply. Also, the new environmental legislation does not help the situation, as it has the potential to shut down generating plants that do not meet the new emissions standard. In addition, there have been problems with the New Build Programme that caused a delay, of over three years, in the delivery of new power, and to compound the problem the Energy Regulator refused recently Eskom’s application for additional tariff increase, which was requested to enable the company provide the finances to cover the shortfall in funding for operational expenses and the New Build Programme. As such, Eskom faces many challenges in meeting its obligation to South Africa, and interventions are in place to manage the situation. In the short term, the key to generation sustainability is improved plant health, brought about by on-time maintenance and correctly-scoped and no-slip outages. This paper presents an overview of the power situation in South Africa, explaining where the country has come from, the plan for long term security of supply, and the challenges faced by Eskom from the generation supply side in meeting the demand load in the short term. Trends in the performance indices indicative of plant health are examined and it is argued that executing planned plant maintenance will improve plant health and, hence, plant availability, which can bring about a turnaround in the short term power supply situation, as Eskom awaits new capacity from the New Build Programme.

Abstract:
Utilities in regulated energy markets manage power generation, transmission, and delivery to consumers. Matching peak demand with peak generation is costly, and the increasing penetration of renewable energy into the grid adds complexity due to fluctuations in supply. A few options exist for addressing the task of balancing supply and demand, including demand response, energy storage, and time-varying pricing (tariffs). Arizona Public Service (APS), the largest electric utility company in Arizona, employs tariffs that charge more for electricity at certain times (on-peak periods) and a demand charge for the highest power demand throughout the billing period. Such tariffs incentivize end users to lower peak demand. Arizona State University (ASU), a public university with its largest campus in Tempe, AZ, participates in a time-of-use tariff structure with APS. Analysis in this paper shows that ASU’s 16MWdc of onsite solar capacity alone can lower its monthly electricity bills by over 10% by decreasing on-peak power demand. A novel contribution of the paper is the analysis of the value of small scale, on-campus energy storage in lowering the demand charge. Most analyses consider savings from transferring off-peak electric power to peak-electric power, but this paper considers using stored electricity solely to reduce peak demand and thus lower the demand charge. Small amounts of electricity could greatly reduce overall cost. An algorithm was developed and executed in Python to decide when on-campus storage should be charged and discharged. The critical part of the algorithm is to decide when to discharge. Deploying too early, or too late, will not change peak demand. The paper’s storage dispatch model is implemented alongside a financial model that calculates the savings in electricity bills and determines the net present value (NPV) of different storage technologies as a function of storage lifetime and installed capacity (kWh). The results show that, for all storage technologies considered, a positive NPV is realized. NPVs are very sensitive to actual power demand and thus vary from year to year. This is to be expected because the storage dispatch strategy operates on extreme values, which tend to include very rare events. This analysis uses actual data from ASU, which allows us to extend the results to other universities and commercial customers. The favorable results suggest that a smarter dispatch algorithm based on machine learning would enable further cost savings by determining what can be thought of as a shadow price of electricity.

Abstract:
Abstract The manufacturing industry is a major source of greenhouse gas emissions (GHG). Additive manufacturing, owing to its multiple advantages, plays a critical role in innovating the current manufacturing industry, especially from a supply chain perspective. Currently, the majority of research on GHG emissions in the manufacturing industry is focused on traditional manufacturing, either single processes in the supply chain or specific case studies, indicating the lack of models on GHG emissions in additive manufacturing-enabled supply chain structures. In this work, a mathematical model is established to estimate the GHG emissions in both traditional manufacturing and additive manufacturing-enabled supply chains. To explore the advantages of additive manufacturing in terms of fast production and reduced or even eliminated the need for assembly and labor involvement, a unique integrated production-inventory-transportation structure is investigated in additive manufacturing case studies. The results indicate that a potential reduction of 26.43% of GHG emissions can be achieved by adopting the additive manufacturing technique in the supply chain. Also, the impacts of rush order rate, emission intensity, and vehicle GHG emission constant rate on the overall GHG emissions are investigated in the sensitivity analysis. Results indicate that a 20% variation in GHG emission intensity (the amount of CO2eq emissions caused by generating a unit of electricity) can lead to a 6.26% change in the total GHG emissions in additive manufacturing.
