Electricity Network Scenarios for Great Britain in 2050

The next fifty years are likely to see great developments in the technologies deployed in electricity systems, with consequent changes in the structure and operation of power networks. This paper, which forms a chapter in the forthcoming book Future Electricity Technologies and Systems, develops and presents six possible future electricity industry scenarios for Great Britain, focussed on the year 2050. The paper draws upon discussions of important technologies presented by expert authors in other chapters of the book to consider the impact of different combinations of key influences on the nature of the power system in 2050. For each scenario there is a discussion of the effects of the key parameters, with a description and pictorial illustration. Summary tables identify the role of the technologies presented in other chapters of the book, and list important figures of interest, such as the capacity and energy production of renewable generation technologies

Equitable Access to Basic Utilities: Public versus Private Provision and Beyond

Providing universal access to basic utilities is justified on human rights grounds and also because of the positive externalities involved. Adequate provision of water, sanitation and electricity contributes to the achievement of the other Millennium Development Goals (MDGs). Access to these services, however, is still unequal in the developing world. Services do not adequately reach the poor. This Poverty in Focus brings together a mix of policy issues and some country experiences. Degol Hailu and Raquel Tsukada provide an overview of the broad challenges involved in making access to basic services equitable and universal. Hulya Dagdeviren and Simon A. Robertson point out the difficulties of expanding utility networks in slum areas, which include technical barriers and a lack of land and housing tenure. They make a case for stronger public interventions. Kate Bayliss argues that the allocation of demand and investment risks during privatisation in Sub-Sahara Africa is distorted. This is because the risks are borne by governments and end users instead of the private contractors. David Hall and Emanuele Lobina provide a critique of both the investment potential of the private sector and cost recovery schemes in the provision of sanitation services. Ashley C. Brown discusses the externalities involved in supplying basic infrastructure to those who can least afford it. He argues that, contrary to established views, cross-subsidy schemes actually benefit all users and not only the targeted population. Alison Post emphasises the benefits of water metering but highlights problems of implementation and poor design in Argentina. Degol Hailu, Rafael Osorio and Raquel Tsukada examine the reasons for the privatisation and then renationalisation of the water supply in urban Bolivia. Andre Rossi de Oliveira explores water privatisation in Brazil. He argues that the expansion of coverage has stemmed mainly from high levels of investment by private operators. Suani Teixeira Coelho, Patricia Guardabassi, Beatriz A. Lora and José Goldemberg note that geographically isolated communities without access to electricity grids, such as those in the Amazon, can be served by renewable energy sources. Luc Savard, Dorothée Boccanfuso and Antonio Estache present the findings of a general equilibrium model that assesses the impact of electricity price changes on the poor in Mali and Senegal. Joana Costa, Degol Hailu, Elydia Silva and Raquel Tsukada empirically show that water provision reduces the total work burden on women in rural Ghana. Nitish Jha conducts a sociological analysis of access to water and sanitation in India, emphasising the challenges encountered in community-based schemes. Julia Kercher explains why and how a human rights framework must guide the design and implementation of private utility provision. We hope that this collection of articles will contribute to the discussion of how to provide vital infrastructure services more equitably. This Poverty in Focus is the result of an International Workshop on Equitable Access to Basic Services held on 5 December 2008 in São Paulo, Brazil. IPC-IG and the David Rockefeller Centre for Latin American Studies at Harvard University (DRCLAS) jointly organised the workshop. We gratefully acknowledge DRCLAS? contribution.

Performance improvement planning : developing effective billing and collection practices

Effective billing and collection systems are a critical component for ensuring the viability of a service provider. Improving billing and collection activities has an immediate impact on the revenue streams of a service provider that can, in turn, help the service provider in improving services. However, while effective billing and collection practices depend on many internal factors (including customer databases, the extent of metered and unmetered service provision, tariff and billing structures, delivery of bills, and facilities for customer payments), the institutional arrangements under which service providers operate and provide services determine whether such practices will remain sustainable in the long term. Efficient billing and collection practices can set incentives for the provider to effectively charge and collect water bills while also fulfilling a commercial orientation to services. This note draws on national and international cases to explore what it takes to implement an effective billing and collection system that encourages commercial and operational efficiencies for aiding the expansion and delivery of improved, reliable, and sustainable services. The note starts with an explanation of how poor billing and collection hurt the service provider, followed by the key principles of an effective billing and collection strategy, illustrated through national and international billing and collection practices.Town Water Supply and Sanitation,Urban Water Supply and Sanitation,Water Use,E-Business,Sanitation and Sewerage

Scenarios for the development of smart grids in the UK: literature review

Smart grids are expected to play a central role in any transition to a low-carbon energy future, and much research is currently underway on practically every area of smart grids. However, it is evident that even basic aspects such as theoretical and operational definitions, are yet to be agreed upon and be clearly defined. Some aspects (efficient management of supply, including intermittent supply, two-way communication between the producer and user of electricity, use of IT technology to respond to and manage demand, and ensuring safe and secure electricity distribution) are more commonly accepted than others (such as smart meters) in defining what comprises a smart grid. It is clear that smart grid developments enjoy political and financial support both at UK and EU levels, and from the majority of related industries. The reasons for this vary and include the hope that smart grids will facilitate the achievement of carbon reduction targets, create new employment opportunities, and reduce costs relevant to energy generation (fewer power stations) and distribution (fewer losses and better stability). However, smart grid development depends on additional factors, beyond the energy industry. These relate to issues of public acceptability of relevant technologies and associated risks (e.g. data safety, privacy, cyber security), pricing, competition, and regulation; implying the involvement of a wide range of players such as the industry, regulators and consumers. The above constitute a complex set of variables and actors, and interactions between them. In order to best explore ways of possible deployment of smart grids, the use of scenarios is most adequate, as they can incorporate several parameters and variables into a coherent storyline. Scenarios have been previously used in the context of smart grids, but have traditionally focused on factors such as economic growth or policy evolution. Important additional socio-technical aspects of smart grids emerge from the literature review in this report and therefore need to be incorporated in our scenarios. These can be grouped into four (interlinked) main categories: supply side aspects, demand side aspects, policy and regulation, and technical aspects.

Information and modeling issues in designing water and sanitation subsidy schemes

In designing a rational scheme for subsidizing water services, it is important to support the choice of design parameters with empirical analysis that stimulates the impact of subsidy options on the target population. Otherwise, there is little guarantee that the subsidy program will meet its objectives. But such analysis is informationally demanding. Ideally, researchers should have access to a single, consistent data set containing household-level information on consumption, willingness to pay, and a range of socioeconomic characteristics. Such a comprehensive data set will rarely exist. The authors suggest overcoming this data deficiency by collating, and imaginatevily manipulating different sources of data to generate estimates of the missing variables. The most valuable sources of information, they explain, are likely to be the following: 1) Customer databases of the water company, which provide robust information on the measured consumption of formal customers, but little information on unmeasured consumption, informal customers, willingness to pay, or socioeconomic variables. 2) General socioeconomic household surveys, which are an excellent source of socioeconomic information, but tend to record water expenditure rather than physical consumption. 3) Willingness-to-pay surveys, which are generally tailored to a specific project, are very flexible, and may be the only source of willingness-to-pay data. However, they are expensive to undertake, and the information collected is based on hypothetical rather than real behavior. Where such surveys are unavailable, international benchmark values on willingness to pay may be used. Combining data sets requires some effort and creativity, and creates difficulties of its own. But once a suitable data set has been constructed, a simulation model can be created using simple spreadsheet software. The model used to design Panama's water subsidy proposal addressed these questions: a) What are the targeting properties of different eligibility criteria for the subsidy? b) How large should the subsidy be? c) How much will the subsidy scheme cost, including administrative costs? Armed with the above information, policymakers should be in a position to design a subsidy program that reaches the intended beneficiaries, provides them with the level of financial support that is strictly necessary, meets the overall budget restrictions, and does not waste an excessive amount of funding on administrative costs.Water Conservation,Environmental Economics&Policies,Health Economics&Finance,Economic Theory&Research,Decentralization,Water Supply and Sanitation Governance and Institutions,Economic Theory&Research,Environmental Economics&Policies,Town Water Supply and Sanitation,Health Economics&Finance

Social Equity Impacts of Congestion Management Strategies

This white paper examines the social equity impacts of various congestion management strategies. The paper includes a comprehensive list of 30 congestion management strategies and a discussion of equity implications related to each strategy. The authors analyze existing literature and incorporate findings from 12 expert interviews from academic, non-governmental organization (NGO), public, and private sector respondents to strengthen results and fill gaps in understanding. The literature review applies the Spatial – Temporal – Economic – Physiological – Social (STEPS) Equity Framework (Shaheen et al., 2017) to identify impacts and classify whether social equity barriers are reduced, exacerbated, or both by a particular congestion mitigation measure. The congestion management strategies discussed are grouped into six main categories, including: 1) pricing, 2) parking and curb policies, 3) operational strategies, 4) infrastructure changes, 5) transportation services and strategies, and 6) conventional taxation. The findings show that the social equity impacts of certain congestion management strategies are not well understood, at present, and further empirical research is needed. Congestion mitigation measures have the potential to affect travel costs, commute times, housing, and accessibility in ways that are distinctly positive or negative for different populations. For these reasons, social equity implications of congestion management strategies should be understood and mitigated for in planning and implementation of these strategies

Public sector pricing policies : a review of Bank policy and practice

Nearly a decade has passed since the Bank codified its position on cost recovery policies (OMS 2.25) for public sector projects. In a review of 13 sectors, the authors find that the Bank guidelines are followed fairly closely in seven sectors: coal, irrigation, oil/gas, power, roads, telecommunications, and water/sewerage. In the other six sectors the focus is heavily on either distributional (health, education, housing) or financial (fertilizer, ports, railways) concerns - with little attempt to incorporate economic pricing principles. Efficiency pricing is not irrelevant or impossible in these sectors, and - even if used only as a benchmark - could improve sector management and project selection and design.Environmental Economics&Policies,Economic Theory&Research,Health Monitoring&Evaluation,Public Sector Economics&Finance,Banks&Banking Reform
