Grid operator TenneT today presented its financial results for the first half of 2023. In addition to solid results, the first six months were marked by a doubling in grid investments and entering into new long-term partnerships. Concerns over congestion remain.
In the first half of 2023, TenneT’s Underlying operating result (“Underlying EBIT”) increased by EUR 351 million to EUR 930 million. IFRS operating result is significantly higher at EUR 1,242 million. This is mainly due to TenneT in Germany being reimbursed for expected grid. The onshore and offshore high-voltage grid operator once again maintained a high grid availability of 99.99997%.
grid expansion and replacement
TenneT invested EUR 3.5 billion in grid expansion and replacement, almost double the amount for the same period last year. This is in line with TenneT’s expectations and earlier announcements of a growing investment portfolio to support the strong political and its intrinsic ambition to drive the energy transition in the Netherlands and Germany.
In addition to TenneT’s solid financial results, the first half of 2023 was marked by solutions and partnerships for the medium and long term, economies of scale. But also security of supply in a carbon-neutral energy system, and international cooperation.
“The huge grid expansion and maintenance task we carry out for the energy transition does not take place overnight. With our hundreds of projects, both onshore and offshore, now and over the next two decades, we are realising the electricity system of the future with a clear end picture in mind: Target Grid 2045. Achieving economies of scale, innovating together with the market, international cooperation and timely and governmental supported long-term infrastructure planning are key in making a carbon-neutral energy system feasible and affordable for households, industries, suppliers and TenneT itself.”
TenneT CEO Manon van Beek
“The societal, political, but certainly also financial efforts regarding the energy transition are of unprecedented proportions. TenneT is gearing up for this. We continue to be engaged in discussions with the German government, to explore a sale of TenneT’s German activities to the German State on acceptable terms. Such a transaction would enable the creation of two strong, national Transmission System Operators (TSOs) with a European focus that will continue to closely cooperate, particularly on the North Sea and that are capable of executing our investment agenda of around EUR 111 billion. The recent shareholder contribution of EUR 1.6 billion and the EUR 8 billion credit facility we concluded in this first half of 2023 provide ample financial headroom.”

Economies of scale and investment security
TenneT concluded several exceptionally large and long-term framework agreements to develop high-voltage infrastructure for the energy transition. These included framework contracts for 14 grid connection systems for offshore wind energy, each with 2GW capacity. These agreements – which include converter stations, cable systems, transportation, and installation – have a total market value of more than EUR 40 billion. With these agreements, new economies of scale and technical standardisation can be achieved, and TenneT can be certain that the suppliers and necessary grid components will be available on time. They also offer suppliers planning certainty and predictability, which they need to be able to invest in necessary additional resources and facilities.
International cooperation as a must
As political goals for large-scale development of offshore wind energy become increasingly ambitious, cooperation between countries and TSOs is no longer a choice. Closer international cooperation is needed to come to a more robust European energy system, connecting more diversified energy sources – including increasing amounts of wind and solar – to maintain a high level of security of electricity supply. This applies especially to offshore energy hubs and hybrid interconnectors. In May this year, TenneT and National Grid Ventures announced LionLink, a new multi-purpose interconnector (MPI) between the Netherlands and the United Kingdom. As well as being an interconnector, it will also transport wind energy from a future 2GW Dutch offshore wind farm. The development is the first of its kind for the UK and the Netherlands, and the first step towards an integrated North Sea grid.
Thanks to innovations like the MPI and the new 2GW standard for offshore grid connection systems, TenneT is playing an important role in developing the North Sea as the powerhouse for Northwest Europe. Together with five other TSO’s, TenneT showed in April 2023 how to achieve large-scale expansion of offshore wind energy in Europe in the joint expert paper The Esbjerg Cooperation: transforming the North Sea into Europe’s green power plant. In the so-called Esbjerg Declaration, Germany, the Netherlands, Belgium, and Denmark agreed to jointly install up to 150 GW of offshore wind energy by 2050, and 65 GW by 2030. To realise that goal, TenneT will connect 40 GW of offshore wind energy in the Netherlands and Germany by 2031.
Preparing high-voltage grids for a future zero-carbon energy system now
With the introduction of Target Grid 2045, TenneT provides a clear design and approach to ensuring that the high-voltage infrastructure at sea and on land needed for a sustainable energy system is completed efficiently and is ready by 2045. Target Grid proposes an internationally meshed grid of direct current (DC) electricity ‘superhighways’ and energy hubs, as well as significant improvements to the existing alternating current (AC) grid. This combination of energy hubs – connected by DC superhighways – ensures that renewable electricity can be transported over long distances from the North Sea to consumers and industry and that the electricity network remains reliable and secure.
Other important developments in H1 2023 in the Netherlands
TenneT delivered the 700 MW offshore grid connection system for Hollandse Kust (Noord). With this, TenneT achieved the objectives of the ‘Offshore Wind Energy Roadmap 2023’ on time and within budget.
TenneT also completed the largest new 380 kV onshore grid connection between Eemshaven and Vierverlaten (40 km) which is now fully operational, including a new high-voltage substation the size of 25 football pitches.
Congestion
TenneT, like other grid operators, suffered delays in grid expansion projects due to nitrogen impasse. This involves 13 projects. According to TenneT, almost 100 projects could be delayed in the long term if there is no solution. In addition, TenneT has to deal with congestion areas. The massive switch to heat pumps, solar panels, electric transport in households and accelerated plans for electrification by businesses is growing faster than the pace at which grid expansions can be executed. As a consequence, the grid is at full capacity in several regions. Grid operators make great efforts to expand the grid and are also developing solutions for the shorter term. To reduce grid congestion in the coming years, grid operators are encouraging businesses and industry to avoid using the grid in peak hours. Unfortunately, interest has been low so far, TenneT says. The National Action Plan aims to provide further insights for businesses, deliver better information and improve incentives for flexibility. Read the full report here. Source: TenneT
