Balancing Mechanism Activity

Keeping the National Grid inputs and outputs in balance is an essential operation. Without the constant attention it would not be long before the frequency of the supplies drifted and power outages resulted.

The exact effect that renewables have on this mechanism can be hard to guage and often results in dramatic headlines of the sums of money involved. The listings below show the daily volumes and cashflows involved for the Balancing Mechanism operation in the hope that this will allow the involvement of renewable energy sources to be seen in context.
