Book Description
The ongoing deregulation of energy markets has greatly impacted the power industry. In this new environment, firms shift their focus from cost-efficient energy supply to more profit-oriented goals, trading energy at the price set by the market. Consequently, traditional management approaches based on cost minimisation disregarding market uncertainties and financial risk are no longer applicable. In this thesis, we investigate medium-term planning problems in deregulated energy markets. These problems typically involve taking decisions over many periods and are affected by significant uncertainty, most notably energy price uncertainty. Multistage stochastic programming provides a flexible framework for modelling this type of dynamic decision-making process: it allows for future decisions to be represented as decision rules, that is, as measurable functions of the observable data. Multistage stochastic programs are generally intractable. Instead of using classical scenario tree-based techniques, we reduce their computational complexity by restricting the set of decision rules to those that exhibit an affine or quadratic data dependence. Decision rule approaches typically lead to polynomial-time solution schemes and are therefore ideal to tackle industry-size energy problems. However, the favourable scalability properties of the decision rule approach come at the cost of a loss of optimality. Fortunately, the degree of suboptimality can be measured efficiently by solving the dual of the stochastic program under consideration in linear or quadratic decision rules. The approximation error is then estimated by the gap between the optimal values of the primal and the dual decision rule problems. We develop this dual decision rule technique for general quadratic stochastic programs. Using these techniques, we solve a mean-variance portfolio optimisation problem faced by an electricity retailer. We observe that incorporating adaptivity into the model is beneficial in a risk minimisation framework, especially in the presence of high spot price variability or large market prices of risk. For a problem instance involving six electricity derivatives and a monthly planning horizon with daily trading periods, the solution time amounts to a few seconds. In contrast, scenario tree methods result in excessive run times since they require a prohibitively large number of scenarios to preclude arbitrage. Moreover, we address the medium-term scheduling of a cascaded hydropower system. To reduce computational complexity, we partition the planning horizon into hydrological macroperiods, each of which accommodates many trading microperiods, and we account for intra-stage variability through the use of price duration curves. Using linear decision rules, a solution to a real-sized hydro storage problem with a yearly planning horizon comprising 52 weekly macroperiods can be located in a few minutes, with an approximation error of less than 10%.

Book Description
In England, it has been possible since 2013 to convert an office building into residential use without needing planning permission (as has been required since 1948). This book explores the consequences of this central government driven deregulation on local communities. The policy decision was primarily about boosting the supply of housing, but reflects a broader neoliberal ideology which seeks to reform public planning in many countries to reduce perceived interference in free markets. Drawing on original research in the English local authorities of Camden, Croydon, Leeds, Leicester and Reading, the book provides a case study of the implementation of planning deregulation which demonstrates the lowering of standards in housing quality, the reduced ability of the local state to proactively steer development and plan for their places, and the transfer of wealth from the public to private spheres that has resulted. Comparative case studies from Glasgow and Rotterdam call into question the very need for the deregulation in the first place.

Book Description
With increasing demand of electric power in the context of deregulated electricity markets, a good strategic planning for the growth of the power system is critical for our tomorrow. There is a need to build new resources in the form of generation plants and transmission lines while considering the effects of these new resources on power system operations, market economics and the long-term dynamics of the economy. In deregulation, the exercise of generation planning has undergone a paradigm shift. The first stage of generation planning is now undertaken by the individual investors. These investors see investments in generation capacity as an increasing business opportunity because of the increasing market prices. Therefore, the main objective of such a planning exercise, carried out by individual investors, is typically that of long-term profit maximization. This thesis presents some modeling frameworks for generation capacity expansion planning applicable to independent investor firms in the context of power industry deregulation. These modeling frameworks include various technical and financing issues within the process of power system planning. The proposed modeling frameworks consider the long-term decision making process of investor firms, the discrete nature of generation capacity addition and incorporates transmission network modeling. Studies have been carried out to examine the impact of the optimal investment plans on transmission network loadings in the long-run by integrating the generation capacity expansion planning framework within a modified IEEE 30-bus transmission system network. The work assesses the importance of arriving at an optimal IRR at which the firm's profit maximization objective attains an extremum value. The mathematical model is further improved to incorporate binary variables while considering discrete unit sizes, and subsequently to include the detailed transmission network representation. The proposed models are novel in the sense that the planning horizon is split into plan sub-periods so as to minimize the overall risks associated with long-term plan models, particularly in the context of deregulation.

Book Description
Bridges the knowledge gap between engineering and economics in a complex and evolving deregulated electricity industry, enabling readers to understand, operate, plan and design a modern power system With an accessible and progressive style written in straight-forward language, this book covers everything an engineer or economist needs to know to understand, operate within, plan and design an effective liberalized electricity industry, thus serving as both a useful teaching text and a valuable reference. The book focuses on principles and theory which are independent of any one market design. It outlines where the theory is not implemented in practice, perhaps due to other over-riding concerns. The book covers the basic modelling of electricity markets, including the impact of uncertainty (an integral part of generation investment decisions and transmission cost-benefit analysis). It draws out the parallels to the Nordpool market (an important point of reference for Europe). Written from the perspective of the policy-maker, the first part provides the introductory background knowledge required. This includes an understanding of basic economics concepts such as supply and demand, monopoly, market power and marginal cost. The second part of the book asks how a set of generation, load, and transmission resources should be efficiently operated, and the third part focuses on the generation investment decision. Part 4 addresses the question of the management of risk and Part 5 discusses the question of market power. Any power system must be operated at all times in a manner which can accommodate the next potential contingency. This demands responses by generators and loads on a very short timeframe. Part 6 of the book addresses the question of dispatch in the very short run, introducing the distinction between preventive and corrective actions and why preventive actions are sometimes required. The seventh part deals with pricing issues that arise under a regionally-priced market, such as the Australian NEM. This section introduces the notion of regions and interconnectors and how to formulate constraints for the correct pricing outcomes (the issue of "constraint orientation"). Part 8 addresses the fundamental and difficult issue of efficient transmission investment, and finally Part 9 covers issues that arise in the retail market. Bridges the gap between engineering and economics in electricity, covering both the economics and engineering knowledge needed to accurately understand, plan and develop the electricity market Comprehensive coverage of all the key topics in the economics of electricity markets Covers the latest research and policy issues as well as description of the fundamental concepts and principles that can be applied across all markets globally Numerous worked examples and end-of-chapter problems Companion website holding solutions to problems set out in the book, also the relevant simulation (GAMS) codes

Book Description
The electricity market has experienced enormous setbacks in delivering on the promise of deregulation. In theory, deregulating the electricity market would increase the efficiency of the industry by producing electricity at lower costs and passing those cost savings on to customers. As Electricity Deregulation shows, successful deregulation is possible, although it is by no means a hands-off process—in fact, it requires a substantial amount of design and regulatory oversight. This collection brings together leading experts from academia, government, and big business to discuss the lessons learned from experiences such as California's market meltdown as well as the ill-conceived policy choices that contributed to those failures. More importantly, the essays that comprise Electricity Deregulation offer a number of innovative prescriptions for the successful design of deregulated electricity markets. Written with economists and professionals associated with each of the network industries in mind, this comprehensive volume provides a timely and astute deliberation on the many risks and rewards of electricity deregulation.
