The paper uses a social cost benefit analysis (SCBA) approach to measure the effects of the power system reform starting from 2015 in Jiangsu province, China. We review the background of Jiangsu power system and summarize the implemented policies since the publication of “Document #9.” Then we pick the average industrial and commercial retail price...
In this paper we explore further how energy network regulation might better be adapted to the uncertainty challenges that are raised by net zero climate policy. We do this with specific reference to energy regulation in the UK. We discuss the drivers of change and the nature of the uncertainty that is faced by energy regulators. Next, we examine th...
Competition usually increases firm productivity; but in network industries, effective competition requires vertical separation, which might reduce productivity and lead to a potential trade-off. We analyze the combined effect of competition and vertical separation on inefficient costs for US electricity industry restructuring. We estimate firm-leve...
This paper seeks to shed light on the nature of optimal regulation of the electricity distribution system operator (DSO) over the period to 2025 and beyond, following the implementation of the EU Clean Energy Package and its constituent parts: Electricity Regulation (EU) 2019/943 and Electricity Directive (EU) 2019/944. We conducted two parallel su...
We analyse the productivity growth of electricity transmission and distribution networks in Great Britain and how changes in incentive mechanism have influenced the measured total factor productivity. In doing so we are also concerned to examine the effects of quality of service and environmental targets on measured productivity growth. It is incre...
This paper quantifies the benefits of introducing reactive power markets that promote the participation of distributed energy resources (DER) in a coordinated way, between the electricity system operator and the electricity distribution utilities. The contribution that DER could make by displacing conventional network assets in supplying reactive p...
The UK left the European single market in energy on 31 December 2020, having been a leading light in its promotion. It entered into a new energy relationship with the EU-27 as outlined in the EU–UK Trade and Cooperation Agreement (TCA) on 1 January 2021. This paper discusses what has happened to the UK energy sector since the Brexit referendum of J...
The rise of intermittent renewable energy generation, the coming mass penetration of electric vehicles and moves to decarbonise the gas grid are leading to widespread innovation experiments within electricity systems and their associated markets[...]
The aim of this paper is to analyse and evaluate the deployment of smart platforms (operated by distribution system operators—DSOs—or by independent parties) in key jurisdictions that facilitate the trading of flexibility services—primarily by DSOs. We look at key innovation projects/initiatives from seven jurisdictions, including Australia, France...
This paper identifies and explores regulatory issues that may have an impact on the use of flexibility services by distribution utilities to solve grid constraints. This can be done by flexible distributed energy resources which can be instructed, for instance, to reduce export generating capacity or increasing consumption. We want to identify how...
This paper draws on international experience to examine how the ongoing power sector reform (PSR) in China since 2015 should be measured and assessed. We proceed by reviewing some relevant international reform experience and then applying this to the Chinese context. Thus we focus on some of the extensive previous literature which has documented re...
For over three decades, air pollution has been a major environmental challenge in many of the fast-growing cities of the world, including Beijing, China. Given that any long-term exposure to high levels of air pollution has devastating health consequences, accurately monitoring and reporting air pollution information to the public is critical for e...
Ancillary services are electricity products which include balancing energy, frequency regulation, voltage support, constraint management and reserves. Traditionally they have been procured by system operators from large conventional power plants, as by-products of the production of energy. This paper discusses the use of markets to procure ancillar...

This paper reviews the international experience in the competitive procurement of reactive power and other electricity ancillary services. It involves system operators from different jurisdictions including Australia, the United States and Great Britain. The paper evaluates the different procurement mechanisms, related compensation schemes and look...
What accounts for the recent widespread slowdown in the productivity in advanced economies has remained a puzzle. One plausible explanation has been attributable to regulation, particularly anti-competitive regulations and environmental regulations. This paper focuses on the regulated energy network sectors by undertaking three sets of analysis in...
This final chapter seeks to summarise some of the key issues emerging from the previous chapters on the prospects for the reform of the Chinese electric power sector. In Sect. 5.1 we begin with some of the high-level messages from the previous four chapters. In Sect. 5.2 we comment on recent developments with the provincial power reform pilots acro...
Guangdong is the largest and the most economically successful province in China. In 2017 Guangdong contributed more than 27.1% of Chinese exports, 10.9% of GDP, 8.1% of the population (c.112 m) and 9.5% of electricity consumption in China. Guangdong has relatively high final electricity prices in China (for residential and most industrial and comme...
This chapter aims to unpack how the price of industrial electricity is determined within the liberalised power market in Great Britain in the context of the ongoing reform of the Chinese power sector, initiated by the March 2015 No. 9 document.
Looking across the world at electricity reform we can identify 14 reform elements that form part of a modern power market reform. We take 11 of these from Paul Joskow (2008) who identifies 11 key components of successful processes and supplement these with 3 additional reform elements appropriate to a low carbon transition (based on Pollitt and Ana...
This chapter introduces the Chinese power system and the background to the reform process which began in March 2015 with the publication of the No. 9 document of the China State Council on ‘Deepening Reform of the Power Sector’. Inter alia, this set of reforms seeks to introduce wholesale power markets to trade electricity under longer- and medium-...
The Chinese electricity sector is the largest in the world, covering well over 20% of the world's electricity supply. While many other countries liberalized their electricity systems in the 1990s, thereby creating competitive wholesale and retail electricity markets, China’s move towards liberalization has advanced at a slower pace – until now.

The aim of this paper is to evaluate different well-established non-electric storage markets (cloud data, frozen food and natural gas) in order to identify relevant lessons for electrical energy storage (EES) connected to electricity distribution networks. The case studies that have been evaluated are Google Drive (cloud storage), Oakland Internati...
The European single market in electricity has been promoted vigorously by the European Commission since 1996. We discuss how national electricity markets and cross-border electricity markets have been reshaped by the process. We examine the Commission’s own work on evaluating the benefits of the single market. We look at the wider evidence of impac...
In virtually all jurisdictions that explicitly price carbon, its average (emissions-weighted) price remains low. Our analysis focuses on the political economy of its introduction as well as its stringency in an international panel of national and North American subnational jurisdictions. Results suggest that political economy factors primarily affe...

Does privatization increase plant productivity because the private owner's objective is different, or because they are better able to control management? And, is privatization sufficient to improve productivity, or is it only effective in combination with competition? We answer these questions using the quasi-experiment of Great Britain's electrici...
China's electric power industry has experienced a reform whereby the generation sector is being opened up to competition but the transmission and distribution sectors are still under regulation. Efficiency and benchmarking analyses are widely used for improving the performance of regulated segments. The impact of observable environmental factors, t...

This chapter discusses a set of possible business models that traditional utilities or new entrants can deploy in order to succeed in the changing energy market. The business models are derived from emerging market models that, in turn, are influenced and shaped by the megatrends driving change. The chapter highlights relevant examples, and the cap...
Multiple market drivers suggest that electrical energy storage (EES) systems are going to be essential for future power systems within the next decade. However, the deployment of the technology is proceeding at very different rates around the world. Whereas the sector is progressing quickly in California, it is not gaining much traction, so far, in...
This paper looks at the empirical and theoretical background to high shares of renewables in the electricity system. First we examine what is meant by ‘high shares’ of renewables; next we consider what we mean by electricity ‘markets’; then we discuss what the term ‘cope with’ implies; before returning to the suitability of ‘current’ electricity ma...
A structural shift from transaction-based, marginal cost pricing to fee-based service business models often accompanies the emergence of “platform” markets, that is, multisided markets where an intermediary captures the value of the interaction between user groups. The many examples include telecommunications, data storage, cinema, music and media,...
This chapter aims to discuss the main socio-economic issues raised by smart grid developments, drawing on the subsequent chapters in this section. These start with cyber-security and privacy concerns. The economic benefits of smart grids are examined, focussing on business-to-business transactions within the electricity system, the system benefits...
Competition increases firms’ performance. But in many industries, especially network
based industries, effective competition requires the separation of firms. Separation
can lead to a trade-off between technical efficiency gains from competition
and losses from separation. But separation itself can be beneficial, too. We estimate
the combined effec...

The electricity industry in most developed countries has been restructured over
recent decades with the aim of improving both service quality and firms’ performance.
Regulated segments (e.g. transmission) still provide the infrastructure for the competitive segments and represent a notable amount of the total price paid by final customers. However...
The complexities of financing, installing, implementing, and regulating public infrastructures, including empirical research, analytical models, and theoretical insights.
Infrastructures—tangible, intangible, and institutional public facilities, from bridges to health care—are a vital precondition for economic and societal wellbeing. There has been...
This study examines the outage loss differential between firms that engage in backup generation and those that do not. Unmitigated outage losses were estimated to be US$2.01-23.92 per kWh for firms engaging in self-generation, and range from US$1.54 to 32.46 per kWh for firms without self-generation. We also find that firms engaging in self-generat...
I am delighted to have been asked to write a chapter in this volume.1 I write as a neo-classical microeconomist with in interests in behavioral economics (i.e., how consumers actually respond to economic information) and new institutional economics (i.e., how institutional structures actually work within the economy). Most of my published work is o...
This paper focuses on how to promote electricity regional cooperation. We begin by discussing the theory of international trade cooperation in electricity, with a view to discussing what preconditions might be important in facilitating wide area trading across national borders.
We then develop lessons based on the comparison of four case studies....
