Energynautics, the German power-systems engineering consultancy based in Darmstadt, was retained by APOLLO-LINK promoter OMNIA GmbH to conduct a connection-point assessment for the planned 2 GW Spain–Italy HVDC interconnector ahead of the project's submission to the ENTSO-E TYNDP 2024 cycle. The scope covered a quantitative comparison of candidate onshore connection points on the Iberian and Italian sides, modelled in PyPSA against a European transmission system snapshot, with the objective of confirming each candidate's technical viability under ENTSO-E's 4th CBA Guideline and the TYNDP 2024 Guidance for Applicants. The analysis estimated usable Net Transfer Capacity (NTC) values in both directions for the new interconnector and identified post-connection grid bottlenecks at each candidate hub. Outputs from this study informed APOLLO-LINK's later route refinement, ultimately moving the preferred connection points from Ramis (ES) / La Spezia (IT) to the Vandellòs (ES) / Marginone (IT) pair confirmed in the developer's April 2026 Media Kit. Project lead at Energynautics was Peter-Philipp Schierhorn (Senior Engineer R&D). The role is recorded as engineering consultancy (NTC modelling, grid impact assessment) and technical advisory (regulatory support for TYNDP project promoter compliance). No public contract value or contract-execution date is disclosed.
