“PROgress on Meshed HVDC Offshore Transmission Networks” is a very precise project description but also a bit lengthy. In contrast, the dynamic acronym “PROMOTioN” refers quite well to the ambitions that the consortium members contribute to the research project. General goal of PROMOTioN is the further development of innovative technologies relevant for the deployment of meshed offshore HVDC nets. The more specific objective is to improve cooperation between grid operators and major suppliers of technical architecture and interoperable technologies to accelerate offshore HVDC grid development. PROMOTioN is the largest energy project funded under the EU Horizon 2020 programme, with a consortium of 33 partners from 11 countries, including the two TSCNET shareholders Energinet, the Danish transmission system operator (TSO), and TenneT, the Dutch-German TSO.
A report by PROMOTioN has just been published (“Regulatory and financing principles for a meshed HVDC offshore grid”) summarising the principal findings for the design of a legal, regulatory and financial framework for cross-border HVDC offshore connections. The report provides recommendations for policy-makers and other stakeholders for overcoming regulatory and financial obstacles to the realisation of a North Sea transmission system. The key conclusion of the report and of the whole project is that the North Sea riparian states need to establish a harmonised legal and economic framework to fully exploit the potential of a meshed offshore grid in the North Sea.
A distinction is made between short-term and long-term recommendations, each of which is presented very concisely. Short term recommendations include the improvement of governance and regulation of the internal market for (offshore) electricity, optimisation of innovation financing, support for early communication of all parties involved and the formalisation of cross-border cost allocation (CBCA) as a binding contract. The latter aspect is regarded as one of the most important pillars in the economic framework. The most significant long-term recommendation is that EU member states, third countries and the EU should consider adopting a North Sea Treaty containing the objectives and principles of the offshore grid.
Tim Meyerjürgens, COO at TenneT, comments on the PROMOTioN project: “The development of a cross-border HVDC grid is one of the most promising opportunities for a sustainable energy future in Europe. TenneT is cooperating closely with other TSOs to develop the idea of a meshed and efficient offshore grid in the North Sea, which requires the creation of a common regulatory framework. PROMOTioN’s research shows the way to make this happen.”
