The Manual Frequency Restoration & Replacement Reserves (mFRR & RR) are implemented by the French TSO, RTE, to balance the power grid. After the secondary reserve, they are used to manually restore the frequency of the power grid.

Flexcity remunerates you for making your flexible power available to the grid (availability remuneration) and the real modulation of this flexible power (activation remuneration).
In 2021, a flexible asset always available could have generated up to 11k€/MW in mFRR of availability remuneration according to market prices, and could have been combined with an additional remuneration from RR.
