Resetting of SDA target for eletricity generation assets for PE firm


I am trying to understand in what circumstances PE firm would have to re-set the SDA target covering eletricity generation assets.

I can see that PE guidance refences acquisitions and divestments on page 62. However, there is no such reference in the FI guidance that needs to be followed for setting SDA (assuming that FI can change the mix of their portfolio towards the renewable energy assets to achieve the target). Can you please clarify the expectation here?
