Demand and production curves in real time

See the demand for each electrical system in real time.

Electricity generation and consumption at all times

We publish the energy demand being registered in the electricity system in real time. These are graphs, the so-called curves, which are updated every five minutes and include data on actual, forecast and programmed demand, as well as the maximum and minimum values of daily demand.

The curves are accompanied by the different production or generation technologies that are needed to meet the demand, including the energy destined for export and consumption of pumped storage. Also shown are the equivalent CO₂ emissions associated with the Spanish generation capacity.

The curves in detail

Real demand or the yellow curve
This shows the current demand for electricity.

Forecast demand or the green curve
We create this using the consumption values for similar periods in the past, correcting this with factors that influence consumption, such as working days, the climate and business activity.

Operational programming or the red stepped line
This is the programmed production for the generators that are matched to the daily and intraday markets as well as the deviation management and tertiary regulation markets. In the Canary and Balearic Islands, where there are no electricity markets, the programme is configured through a technical-economic office.

We provide you with the electricity demand and production curves for each electricity system in Spain.

CO₂ emissions associated with electricity generation

Learn about the emission factor for each system, expressed in t CO₂ eq/MWh and also the details related to emissions by time and technology. We use different sources to calculate the emission factors for each technology and system, based on the best information available.
