Regulation electricity (RE)

Electricity procured in real time by the transmission system operator (TSO) to balance system deviations, ensuring the stability of the transmission system and the quality of electricity. Regulation electricity can be positive or negative. Positive regulation electricity balances positive system deviations (i.e. excess electricity in the power grid) and requires an increase in electricity production from energy sources or a decrease in consumption on the part of customers. Negative regulation electricity compensates for negative deviations in the system (i.e. a lack of electricity in the power grid), and necessitates a reduction by producers or an increase in consumption by consumers.
