Gather information related to reduced costs of operating the TenneT grid from better power forecasts (part 2)

[MartijnCa]

Acceptance criteria:

1. Answers to the following questions have been documented:
   • Would better transmission forecasts allow TenneT to connect more parties to the existing grid? (At Alliander it does: good forecasts >> congestion management successfully possible >> possible to have more customers connected on the same grid.)
   • Would better transmission forecasts alleviate the need for TenneT to expand the grid (and reduce expected CAPEX)? Since the grid can be used more efficiently when transmission forecasts are good better.
2. Insights have been provided and documented on the SharePoint with respect to:
   • Development of costs of the grid (+80-120% in 2023) (CAPEX).
   • Growing costs for congestion management, redispatch, balancing (OPEX).
