Background The Utility Regulators Forum was established in recognition of the need for cooperation in a federal system among State-based regulators. The forum consists of regulators operating in industries where utilities that traditionally operated as monopolies are being opened up to competition as a result of the competition reform process. By acting as a focal point for regulators in different jurisdictions the forum seeks to: < foster understanding of issues and concepts faced by regulators on similar industries; < minimise overlap of regulations for large users who operate across jurisdictions; < provide a means of exchanging information; and < enhance the prospects of consistency in the application of regulatory functions. The following paper is released by the Regulators Forum to encourage discussion in a range of important regulatory issues. CONTENTS 1.

Introduction Since the creation of the National Electricity Market (NEM), there have been criticisms of the different regulatory reporting requirements imposed by the various jurisdictional regulators. Although the transmission sector has almost completed its move towards a national regulatory framework under the ACCC, the remaining sectors (generation, distribution and retail) retain a significant element of State or Territory based regulation. With the different jurisdictional legal frameworks, requirements for information vary; in general, each jurisdiction has continued to collect information in the form that it was collected prior to the NEM. This has resulted in the need for businesses operating in multiple jurisdictions to collect their data in jurisdiction-specific forms. Indeed, many businesses only have the capability to collect data in the form collected prior to the NEM. Such differing requirements have prevented cross-jurisdictional businesses from achieving economies from a single data base collection system, and also made it difficult to compare performance across jurisdictions. Accordingly, in November 2000 the Utility Regulators Forum agreed that jurisdictional economic regulators would develop a core set of nationally consistent performance reporting requirements covering the electricity industry. A Steering Committee on National Regulatory Reporting Requirements was established to oversight the development of the requirement for reporting of: < service performance of electricity distributors; < financial performance of electricity distributors; and < service performance of electricity retailers. The Steering Committee comprised representatives of jurisdictional and national electricity regulators and relevant departments from NSW, Victoria, ACT, Queensland, Tasmania and South Australia. Three working groups were established comprising staff from the above regulatory organisations and electricity industry representatives nominated by the Electricity Supply Association of Australia. Draft proposals were distributed for comment to the industry and other interested parties in August 2001, and comments received were reviewed by the working groups. Final draft proposals were submitted to the Steering Committee in December 2001 for approval. National Regulatory Reporting for Electricity Distribution and Retailing Businesses 1 This document presents the outcome of the above process, and sets out the agreed national regulatory reporting framework for the three areas covering the electricity distribution and retailing sectors. National Regulatory Reporting for Electricity Distribution and Retailing Businesses 2 2. Electricity Distribution Businesses Distribution network service providers (DNSPs) operate a network of low voltage substations and wires that transport electricity from distribution centres to end-use customers. These utilities may be either privately or publicly owned. The networks must be maintained and operated securely and in a manner that provides open access to participants who trade in the national electricity market and to smaller operators who trade directly with local retailers. DNSPs are regulated businesses whose prices and service standards for prescribed services are set by independent regulators. Each State and Territory jurisdiction has its own regulator, and each has developed different reporting requirements for DNSPs operating in their jurisdiction. The Steering Committee was established to determine a common reporting framework acceptable to all jurisdictions. 2.1 Distribution Quality of Service The objective of the Quality of Service Working Group was to review and compare the measures of network service quality currently used by regulators, and develop performance measures that can be collected on a consistent and reliable basis across the jurisdictions. The Working Group’s terms of reference required it to develop quality of service measures having regard to: < the costs of measurement and data collection; < their appropriateness as a basis for performance benchmarking; < compatibility with measures currently used by jurisdictions; < the extent to which they reflect and encompass issues of concern to customers; < the availability of data to calculate the measure. While the Working Group recommended measures that in its view balanced the above objectives, selection of performance measures was primarily driven by the availability of data in the short-term. The measures proposed are or should be monitored by distributors in the normal course of their business. However it is recognised that in some cases there are deficiencies in the information currently available, and further work is needed to improve the quality of performance measurement. As a number of submissions noted, much of the data currently collected and the systems for recording the data serve the objective of asset management rather than monitoring the quality of service provided to customers. National Regulatory Reporting for Electricity Distribution and Retailing Businesses 3 Submissions also noted that improved monitoring and reporting of some performance measures may involve additional investment in capital equipment and in the analysis and reporting of data. To the extent that this is so, there is a balance to be struck between the benefits of more accurate and comprehensive performance monitoring and the costs of measurement and reporting. The Steering Committee identified a number of areas in which improved reporting would serve to facilitate the comparison of distributors’ performance, and potentially provide information on future network investment priorities. These issues, discussed below, will be considered by the Steering Committee when the regulatory reporting framework is reviewed. However, in some cases enhanced performance reporting may be dependent on jurisdictional regulators approving additional expenditure. While performance measures for network reliability are widely used in a standardised format, there are limitations with the current systems and practices for monitoring and calculating reliability performance that impact on the robustness and comparability of reported data. These include: < where distributors’ information systems do not provide connectivity data that links individual customers to a part of the physical network, customer-weighted reliability measures (such as SAIDI and SAIFI) are based on estimates of customer numbers.

    ELECTRICITY RETAILING DECISION MAKING BASED ON DATA MINING TECHNIQUES By JIAJIA YANG B.E. M.E. A thesis in fulfilment of the requirements for the degree of Doctor of Philosophy School of Electrical Engineering and Telecommunications Faculty of Engineering April 2018 PLEASE TYPE THE UNIVERSITY OF NEW SOUTH WALES Thesis/Dissertation Sheet Surname or Family name: Yang First name: Jiajia Other name/s: Abbreviation for degree as given in the University calendar: PhD School: School of Electrical Engineering and Faculty: Faculty of Engineering Telecommunications Title: Electricity Retailing Decision Making Based on Data Mining Techniques Abstract 350 words maximum: (PLEASE TYPE) With the continuous development of Smart Grid, especially the emergence of Energy Internet, there is an increasing amount of measurement data available collected from power system end-users. Through data mining techniques, these measurement data can enable a better understanding of the load composition and end-user consumption behaviours, and therefore would provide great potentials for developing more flexible and targeted or even customized pricing schemes for electricity retail. This research starts with a comprehensive literature survey on decision-making for electricity retailers. Publications on electricity retailing in the last two decades are surveyed and discussed in detail. Then, key business framework of electricity retailers is studied. It elaborates the typical business process of electricity retailers and its procedure of creating a new sales agreement. Considering the drawbacks of existing load data mining methods, a new non-intrusive load monitoring method is proposed which is able to cope with the big load data in the Smart Grid environment. After obtained the status of all identified appliances, a statistical residential load model is developed.

In order to balance the need for the Electricity Distribution Industry (EDI), to improve its livelyhood, to obtain reasonable returns on investment, to deliver services at least cost to needy and poor communities, it has become imperative to address issues of electricity industry restructuring, corporatization, privatisation and the socio-economic upliftment. On the other hand, in order to ensure development and sustainability of the South Africa economy, it is equally imperative to ensure lower input costs to the industrial sector, which is the backbone of the economy. This is particularly so in respect of bulk consumers of electricity. The challenge will always be how to strike a balance between ensuring sustainability and facilitating growth of the Electricity Supply Industry (ESI) and the socio-economic demands placed upon it.

  • Implication of Competition Law Enforcement in the Electricity Sector: Comparative Analysis of the UK and the US
    Francisca Kusi-Appiah Implication of Competition Law Enforcement in the Electricity Sector: Comparative Analysis of the UK and the US Introduction Competition policies and laws are being adopted and introduced by countries, especially developing countries, in order to gain investment. 1 This research examines literature on competition in the energy sector with specific focus on electricity. Critical analysis is made of the competition legal regimes as exist in the electricity markets of UK (England and Wales, and Scotland) and US (PJM). The comparative analysis of the implication of competition on electricity in the US (PJM) and the UK electricity or power markets will rely on indicators for both competition and electricity security. The indicator for competition will consist of the substantive competition law/legal regime while the indicators for electricity security, will consist of availability (generational capacity), fuel diversity (environmental concerns) and affordability. Competition Legal Regime United States Competition in the electricity markets in the United States started in the 1990s but majority of the states adopted this new approach in the 2000s. 2 In 2000, the Federal Energy Regulatory Commission introduced independent system operator (ISO) or regional transmission organisation (RTO) and in October of that same year, FERC 1 Francisca Kusi-Appiah ordered the compulsory adoption of either an ISO or RTO by all utilities. 3Competition in the Unites States of America was only in respect of wholesaling. 4 Currently, most states have implemented competition of electricity retailing with the emergence of electricity service providers who do not have to produce their own electricity but buy from the market place and resell to consumers.

    COVER STORY Energy Solutions for Future Earth Activities 1 Achieving a Sustainable Society through Digital Innovation in the Electric Power Industry —Establishing Digital Solutions for the North American Power Grid— The deregulation of electricity retailing, combined with greater adoption of renewable energy sources and distrib- uted generation have produced advances in digital technologies that are bringing major changes to the energy industry. This trend is occurring throughout the global market and in the electric power industry in particular. The changing nature of this industry is driving the value chain towards more sophisticated ways of operating power plants, maintaining equipment, realigning roles, and reordering the relationships between suppliers and consum- ers. The traditional model is evolving toward a system of supply and demand, away from the tightly regulated systems and practices that once governed the main grid. With this as a backdrop, electric utilities are starting to recognize that the use of digital technologies will result in superior operating decisions that are based on effective data management. For example, greater integration and compatibility between in-house systems incorporating fi eld data from the grid can use that data for improving performance measures. In North America, a market where electric utilities number more than 3,000 companies, Hitachi is engaging in collaborative creation with customers in order to incorporate digital solutions that address the challenges facing customers. These solutions

This research study aims to give a global overview of the digital transformation and channel integration of free-market electricity retailers in Spain from a consumer’s perspective. The analysis includes all free-market electricity retailers that operate at the national scale, explores the level of digital transformation and channel integration of these companies based on a structured set of indicators, and measures them using the mystery shopper technique. The results show important differences between leading retailers and the rest of companies, evidence an important lag of the sector when compared to other retail markets and an overall lack of multichannel and omnichannel strategies, show a strong effort of retailers in online billing and self-service customer data management, and reveal shortcomings in the availability of communication channels with customers.

  • Avoiding Pitfalls in Reforming China's Electricity Sector
    Pre-publication version, accepted to The Energy Journal, 2020 Avoiding Pitfalls in China’s Electricity Sector Reforms† * ** Michael R. Davidson and Ignacio Pérez-Arriaga China has recently reinvigorated reforms to its electricity sector, focusing on increasing the role of markets and improving regulation. While restructuring an electricity sector is difficult and can require years of detailed planning, China’s approach relies upon broad central guidelines with many details and initiatives left to provincial governments. We assess the current state of reform efforts through the lens of five “pitfalls” based on well-established regulatory economics literature and international lessons, focusing on contract structure, system operation, and regulation. We find that while market efforts are likely to achieve efficiency gains with respect to the planned system, they may fall short of crucial functions of a market, such as incentivizing flexibility given increasing renewable energy penetrations. Making markets work will likely require a stronger centralization of market design and regulatory oversight authorities.
