Surveys the current situation and market status of distributed generation in selected OECD countries, including the impact of current energy policies.
This volume contains data on the supply and consumption of coal, oil, gas, electricity, heat, renewables and waste presented as comprehensive energy balances expressed in million tonnes of oil equivalent.
This paper seeks to assess the impact of liberalisation and privatisation on performance in the generation segment of the electricity supply industry. Regulatory indicators for a panel of 19 OECD countries over a 10 year time period were constructed to examine the influence of regulatory reform on efficiency, price, and quality, and to assess the relative efficacy of different reform strategies. The presence of data with both cross-country and time-series dimensions allows separate identification of country specific and regulatory effects. The primary findings are that while changes in legal rules may be slow to translate into changes in conduct, unbundling of generation, private ownership, expanded access to transmission networks, and the introduction of electricity markets impact the performance measures in a statistically significant way, on average.
This book analyses the development of choice and competition in the Electricity Supply Industry (ESI). Drawing on a review of the international experience, it describes the main approaches that are being developed, discusses the key issues in the effective reform of electricity markets and provides an assessment of the emerging approach to reform. The book is written from the perspective of regulators and policy makers. It seeks to answer the question: what is an effective regulatory framework for competition in electricity markets?
Wind power and solar photovoltaics (PV) are crucial to meeting future energy needs while decarbonizing the power sector. Deployment of both technologies has expanded rapidly in recent years, one of the few bright spots in an otherwise bleak picture of clean energy progress. However, the inherent variability of wind power and solar PV raises unique and pressing questions. Can power systems remain reliable and cost-effective while supporting high shares of variable renewable energy (VRE)? And if so, how? Based on a thorough review of the integration challenge, this publication gauges the economic significance of VRE integration impacts, highlights the need for a system-wide approach to integrating high shares of VRE and recommends how to achieve a cost-effective transformation of the power system. This book summarizes the results of the third phase of the Grid Integration of VRE (GIVAR) project, undertaken by the IEA over the past two years. It is rooted in a set o
This comprehensive overview explores the policy issues and other factors affecting the future of nuclear power in OECD countries. It provides a wealth of historical and current information of interest to both energy industry professionals and policy makers. Nuclear power has grown steadily since the early 1960s. Today it provides one quarter of OECD electricity supply from 300 GWe capacity. It is an important contributor to OECD energy security. Existing nuclear plants appear ready to meet the challenges of electricity market competition. The industry has experienced sustained improvements in technical and economic performance. A major advantage of nuclear power is that it produces none of the airborne pollutants or carbon dioxide that fossil-fuelled plants do. Nonetheless, nuclear power must cope with many challenges. New nuclear plants face formidable competition from fossil fuel generation, given nuclear power s high capital cost and today s fossil fuel prices. Almost half of OECD countries have placed restrictions on building nuclear power plants. Disposal facilities for high-level wastes are under development, but face technical and political hurdles before they can become operational. Can nuclear power meet these challenges and thrive in future energy markets? Or will its contribution to energy supply ebb in coming years? This book provides a critical assessment of the issues that will shape the answers to these questions.
This publication provides host country governments with guidance on the policy options that are available to make the most of investment opportunities in clean energy infrastructure, drawing on the expertise of climate and investment communities among others. It identifies key issues in investment policy, investment promotion and facilitation, competition, financial markets, and public governance. It also addresses cross-cutting issues, including the implications of regional co-operation and of international trade for investment in clean energy infrastructure.
This report addresses the increasingly important interactions of variable renewables and dispatchable energy technologies, such as nuclear power, in terms of their effects on electricity systems. These effects add costs to the production of electricity, which are not usually transparent. The report recommends that decision-makers should take into account such system costs and internalise them according to a "generator pays" principle, which is currently not the case. Analysing data from six OECD/NEA countries, the study finds that including the system costs of variable renewables at the level of the electricity grid increases the total costs of electricity supply by up to one-third, depending on technology, country and penetration levels. In addition, it concludes that, unless the current market subsidies for renewables are altered, dispatchable technologies will increasingly not be replaced as they reach their end of life and consequently security of supply will suffer. This implies that significant changes in management and cost allocation will be needed to generate the flexibility required for an economically viable coexistence of nuclear energy and renewables in increasingly decarbonised electricity systems.
Electricity Information provides a comprehensive review of historical and current market trends in the OECD electricity sector. It provides an overview of the world electricity developments covering world electricity and heat production, input fuel mix, supply and consumption, and electricity imports and exports. More detail is provided for the OECD countries with information covering production, installed capacity, input energy mix to electricity and heat production, consumption, electricity trades, input fuel prices and end-user electricity prices. It provides comprehensive statistical details on overall energy consumption, economic indicators, electricity and heat production by energy form and plant type, electricity imports and exports, sectoral energy and electricity consumption, as well as prices for electricity and electricity input fuels for each country and regional aggregate.Electricity Information is one of a series of annual IEA statistical publications on major energy sources; other reports are Coal Information, Natural Gas Information, Oil Information and Renewables Information.
