Managing the Seasonal
Variability of Electricity
Demand and Supply
The IEA examines the full spectrum of energy
issues including oil, gas and coal supply and
demand, renewable energy technologies,
electricity markets, energy efficiency, access to
energy, demand side management and much
more. Through its work, the IEA advocates
policies that will enhance the reliability,
affordability and sustainability of energy in its 31
member countries, 13 association countries and
beyond.

Managing the Seasonal Variability of Electricity Demand and Supply
PAGE | 3
Abstract
Abstract
Electrification of end-uses and the growth of solar and wind is
changing how electricity systems operate on all time scales. This
report analyses how seasonal variations in 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 power system costs. The study
finds that, in each system, both short-term and seasonal flexibility
needs rise considerably to 2050. Flexibility, currently provided by
thermal power plants and hydro, will increasingly come from new
sources demand response and batteries on shorter timescales and
hydrogen across weeks to seasons with low emissions thermal
power plants and hydro remaining important providers of seasonal
balancing. As the systems become more capital-intensive,
consumers are increasingly insulated from the impact of weather
variations on power plant operations and the volatility of fossil fuel
prices.
This work expands on the report Managing Seasonal and Interannual
Variability, published in April 2023 which assesses the impact of
weather-related variability on system operations across seasons and
between years in different climatic zones.
