On behalf of Ørsted, Ea Energy Analyses has carried out a study on synergies between substantial offshore wind power buildout and the increasing need for transmission grid to support a decarbonized European energy system.
The study models a decarbonisation of Europe towards 2050, based on assumptions derived from the European Commission’s 1.5 TECH-scenario, and carried out using the power system model Balmorel.
The modelling considers different options and costs of connecting the European offshore wind potential to the load centres. Additionally, effects of P2X-demand, which play an important role in the European Commission’s vision for the European energy system, are modelled and analysed.
The study shows that combining offshore wind with transmission in multilinked (hybrid) farms can contribute to decreasing the total investments in infrastructure. In addition, CO-optimization of the location of P2X-plants with multilinked projects leads to system benefits and substantially reduces transmission capacity needs, thereby contributing to a lower cost of decarbonizing Europe.
