IEA – Monthly Electricity Statistics

The latest IEA’s Monthly Electricity Statistics report including May 2023 data shows that for Total OECD:


In the OECD, total net electricity production amounted to 831.5 TWh in May 2023, down by 3.9% compared to the same month last year.

This decrease was led by reduced generation from fossil fuel sources (-9.8% y-o-y), driven by coal (-19.7% y-o-y) and natural gas (-4.3% y-o-y). Overall, the share of fossil fuels in the OECD electricity mix plunged to 45.2%, around three percentage points lower than in May 2022.

Total electricity production from renewable sources slightly increased 1.5% y-o-y, as strong generation from solar (+ 15.1% y-o-y) and hydropower (+2.2% y-o-y) compensated for lower wind power output (-7.3% y-o-y). The share of renewables in the OECD electricity mix reached 38.2%, up by two percentage points y-o-y.

Nuclear power increased 2.0% y-o-y, as reduced output in OECD Europe (-1.4% y-o-y) and in the OECD Americas (-1.1% y-o-y) was offset by higher production in OECD Asia-Oceania (+25.8% y-o-y). Overall, the share of nuclear power in the OECD electricity mix remained stable at 16.3%.



Highlight of the month:

In Serbia, electricity production from hydropower amounted to 1.3 TWh in May 2023, up by 42.8% compared to the same month last year. This was the result of increased rainfall in the country, which boosted water inflows in major hydropower plants. Overall, the share of hydropower in Serbia jumped to a record-high of 48.2%, overtaking coal (43.8% share) as the country’s largest source of electricity in May 2023.



The IEA’s Monthly Electricity Statistics features electricity production and trade data for all OECD Member Countries and electricity production data for a selection of other economies. The latest dataset is available below in CSV.

We have now moved to a new integrated platform and in order to access data, all users will need to login using their IEA account. If you would like to access the data, please create your IEA account on this page. Once you are logged in, you can download the dataset here.

EMR Analysis

More information on IEA (International Energy Agency): + The IEA is at the heart of global dialogue on energy, providing authoritative analysis, data, policy recommendations, and real-world solutions to help countries provide secure and sustainable energy for all.

The IEA was created in 1974 to help co-ordinate a collective response to major disruptions in the supply of oil. While oil security this remains a key aspect of our work, the IEA has evolved and expanded significantly since its foundation.

Taking an all-fuels, all-technology approach, the IEA recommends policies that enhance the reliability, affordability and sustainability of energy. It examines the full spectrum issues including renewables, oil, gas and coal supply and demand, energy efficiency, clean energy technologies, electricity systems and markets, access to energy, demand-side management, and much more.

Since 2015, the IEA has opened its doors to major emerging countries to expand its global impact, and deepen cooperation in energy security, data and statistics, energy policy analysis, energy efficiency, and the growing use of clean energy technologies.

More information on OECD (Organisation for Economic Co-operation and Development): + The OECD is an international organisation that works to build better policies for better lives. Our goal is to shape policies that foster prosperity, equality, opportunity and well-being for all. We draw on 60 years of experience and insights to better prepare the world of tomorrow.

Together with governments, policy makers and citizens, we work on establishing evidence-based international standards and finding solutions to a range of social, economic and environmental challenges. From improving economic performance and creating jobs to fostering strong education and fighting international tax evasion, we provide a unique forum and knowledge hub for data and analysis, exchange of experiences, best-practice sharing, and advice on public policies and international standard-setting.
