Enhancing cyber resilience in electricity systems
…of cyberattacks on electricity systems is substantial and growing. Threat actors are becoming increasingly sophisticated at carrying out attacks. A successful cyberattack could trigger the loss of control over devices and processes, in turn causing physical damage and widespread service disruption.While the full prevention of cyberattacks is not possible, electricity systems can become more cyber resilient – to withstand, adapt to and rapidly recover from incidents and attacks, while preserving the continuity of critical infrastructure operations. Policy makers, regulators, utilities and equipment providers have key roles to play in ensuring the cyber resilience of the entire electricity value chain.Policy…

Secure energy transitions in the power sector
…of electricity security. In order to address risks to adequacy in the long term and operational security in the short term, regulations and market designs must ensure that all system resources are compensated in accordance with their system value. New products will need to be created in response to the development of flexibility sources such as dispatchable generation, demand response, storage, digitalisation and interconnections. Policy makers should particularly focus on the role distributed energy resources, energy source diversity, energy efficiency and fuel security will play in ensuring a secure and resilient power system at lowest cost to consumers.

Saving Electricity in a Hurry 2011
Saving Electricity in a Hurry 2011 As demonstrated by the March 2011 earthquake and tsunami-triggered blackouts in Japan, electricity shortfalls can happen anytime and anywhere. Countries can minimise the negative economic, social and environmental impacts of such electricity shortfalls by developing emergency energy-saving strategies before a crisis occurs. This new IEA report, Saving Electricity in a Hurry: Update 2011, highlights preliminary findings and conclusions from electricity shortfalls in Japan, the United States, New Zealand, South Africa and Chile. It draws on recent analysis to reinforce well-established guidelines on diagnosing electricity shortfalls, identifying energy-saving opportunities and selecting…

Climate and Electricity Annual 2011
…fuels, electricity is also the largest and the fastest-growing source of energy-related CO2 emissions, the primary cause of human-induced climate change. Forecasts from the IEA and others show that “decarbonising” electricity and enhancing end-use efficiency can make major contributions to the fight against climate change. Global and regional trends on electricity supply and demand indicate the magnitude of the decarbonisation challenge ahead. As climate concerns become an essential component of energy policy making, the generation and use of electricity will be subject to increasingly strong policy actions by governments to reduce their associated CO2 emissions. Despite…

Managing the Seasonal Variability of Electricity Demand and Supply
…both demand and supply affect electricity system operations to 2050 – in Europe, India, Indonesia and Korea – and what sources will be used to manage them. Seasonal variations are put in context with the annual electricity mix and short-term (hourly) variability. Each of the analysed regions has a unique electricity mix today, available resources, geographies, and patterns of electricity demand. Each has charted a different course for their clean energy transitions and is located in different climatic zones. This study also recognises that weather conditions are uncertain and vary from year-to-year, exploring their impact on system operations and…

Electricity Security Policy
…regulatory and economic uncertainty, create a more complex infrastructure investment environment.The IEA Secretariat has developed an integrated assessment framework to incorporate electricity security assessments into emergency response reviews, including the impact of climate resilience on electricity infrastructure and growing cybersecurity threats. The IEA has outlined three strategic areas to assess electricity security: generation adequacy, regional market integration and variable renewable generation. These strategic areas all affect electricity reliability, security and adequacy.As the IEA expands its analysis on energy security beyond the oil industry, to include natural gas and electricity, an interconnected vision of all three energy sources has…

Electricity 2025
…it forecasts electricity demand, supply and carbon dioxide (CO2) emissions for select countries, by region and worldwide. The report explores emerging trends such as growing electrification, expanding power systems and an increasing share of weather-dependent energy sources in the generation mix. Through this lens, it assesses resource adequacy and the methods needed to ensure the security, resilience and reliability of power systems and electricity supply. This year’s report, now in its sixth year, includes a special feature on China’s evolving power demand as well as a section on the phenomenon of negative wholesale electricity prices in some…

Securing Power during the Transition
…However, policies to decarbonise electricity systems have served to magnify investment risk and uncertainty. At the same time as renewable support schemes have proven effective in facilitating deployment of wind and solar photovoltaics, they also introduce new challenges to design a stable regulatory framework and well-functioning markets. Securing Power during the Transition assesses the threats and identifies options for competitive electricity markets embarking on the transition towards generating electricity from low-carbon sources. The analysis covers the impact of the global economic and financial situation, energy policy context and the implications for electricity market design. Its objective is to…

Learning from the Blackouts
…a more integrated and dynamic network environment with new real-time challenges for reliable and secure transmission system operation. These operational challenges are intensified as spare transmission capacity is absorbed. The major blackouts of 2003 raised fundamental questions about the appropriateness of the rules, regulations and system operating practices governing transmission system security. Despite the considerable efforts since 2003 to address the weaknesses exposed by the blackouts, it can still be argued that the development of these rules and operating practices have not kept pace with the fundamental changes resulting from electricity market reform. More can and should be done.

Global Energy Review 2019
…well below the average rate since 2010. This deceleration was due mainly to slower global economic growth and the impact of milder weather on heating and cooling.
There was, however, significant variation across energy sources, with coal showing an absolute decline and renewables a record increase. Electricity demand grew at the slowest rate since the financial crisis. Energy efficiency continued to improve but at levels well below those needed to meet the Sustainable Development Goals. Energy-related CO2 emissions remained flat as emissions from electricity generation in advanced economies declined markedly.
