Physical operations

We report on several physical characteristics of an asset which we estimate from the available data

Throughput

Energy throughput is calculated as the energy exported by an asset whilst delivering frequency response services, and for balancing mechanism units, energy exported into the wholesale market and balancing mechanism.

The throughput of delivery frequency response services is calculated using 1 Hz grid frequency data - you can read more about how we calculate the power output of an asset delivery frequency response services here.

For balancing mechanism units, we calculate the energy exported into merchant markets by integrating the area under an asset's physical notifications, and combine this with the volume dispatched into the balancing mechanism.

Throughput from wholesale markets are not estimated for non-balancing mechanism units as we do not have visibility over their wholesale positions.

Cycling

Cycling is calculated as the energy throughput, divided by the asset's energy capacity (MWh).
