Power-to-gas plants are flexible and responsive. This makes them perfect for providing balancing energy. PtG can provide negative balancing power. This takes effect when there is too much electricity in the grid. Then the feed-in must be reduced or the demand increased in order to stabilise the grid frequency within the limits. An additional benefit is that the gas generated in this way can also be kept. Furthermore, power-to-gas plants can additionally provide positive balancing energy during continuous operation by shedding load, i.e. reducing their electricity demand.
