We introduce you redOS, the app of Red Eléctrica de España, which allows you to know, in real time, the situation of the electricity system through a set of indicators of the system operation. You can choose between two user profiles: a “consumer” profile that allows you to become an active player in the energy transition, as consumer and self-consumer; and a “professional” profile where you will find extended information on generation, demand, prices and exchanges to be always informed on the current situation of the electricity system. You can find the following information categories: • Electricity demand. • Generation. • CO2 emissions. • Installed power. • Electricity exchanges. • Wholesale prices. • Retail prices.
