Wake gain from stopped turbines¶
A stopped turbine produces no wake. The turbines downstream of it therefore produce more than they would if it were running.
"Production at 100% availability" is the production with every turbine running, as assumed by the model. It therefore excludes this gain, which is added back as a separate step of the energy chain, "Wake gain from stopped turbines", next to the stopped loss, so that the energy chain ends at the measured production.
For a running turbine at a given timestep, the wake gain is its simulated power with the actual availability of the turbines minus its simulated power with every turbine running.
Example: the upstream neighbour of a turbine is stopped for one hour. During that hour, the turbine produces 1.20 MWh instead of the 1.00 MWh it would have produced behind a running neighbour. The wake gain is 0.20 MWh. The production at 100% availability includes 1.00 MWh for this turbine, and the energy chain adds the 0.20 MWh as a separate gain.
For datasets processed before this step was introduced, the wake gain from stopped turbines is reported as zero; Actual (100% availability) then includes the gain.
