Background

The Fraunhofer Institute for Solar Energy Systems is a German applied-research body headquartered in Freiburg. Alongside its core solar and hydrogen research, it operates energy-charts.info, a public platform that aggregates power price and generation data rather than generating its own readings.

The platform draws Germany's day-ahead and balancing figures from SMARD, the Bundesnetzagentur's market data register, and cross-border generation and flow data from ENTSO-E, the European transmission operators' association. Both feeds are republished through a single API under a CC BY 4.0 licence, so the underlying figures are regulator-derived rather than aggregator-sourced.

That distinction is what gives energy-charts.info its standing as a citation source: a price or generation figure pulled through it traces back to SMARD or ENTSO-E rather than to a commercial data reseller, which is why this desk uses it for German and French power-price comparisons rather than pricing services covering gas or carbon.
