North see Energy island already above cost estimations

The North Sea energy island project, also known as the Princess Elisabeth Island, is a key initiative in Belgium's federal energy policy. The artificial island, being constructed by Belgian dredging companies DEME and Jan De Nul and operated by high-voltage grid operator Elia, is designed to act as a hub for offshore wind energy. Its purpose is to connect new offshore wind farms to the mainland electricity grid while also linking Belgium to an international wind farm network in the North Sea. The project is considered vital for supporting Europe's climate goals and renewable energy transition.

Initial Vision and Cost Estimates

Originally, the energy island was estimated to cost €2.2 billion when plans were unveiled in 2021. However, due to rising material costs, supply chain pressures, inflation, and increased ambition in renewable energy targets, the estimated cost has ballooned to €7 billion. This cost surge has raised concerns among energy regulators, businesses, and consumers.

The island is expected to connect three offshore wind farms by 2030 and eventually facilitate undersea cables to the UK, Denmark, and other North Sea countries. These interconnections would allow countries to balance their energy needs by compensating for drops in wind power in one region with energy generated in another.

Factors Driving Cost Increases

Several factors have contributed to the dramatic rise in costs:

A) Supply Chain Pressures and Inflation: Global supply chain disruptions and rising prices of essential materials have significantly increased the cost of high-voltage infrastructure.

B) Technical Challenges: The inclusion of a direct current (DC) component, which is critical for long-distance energy transmission, has become notably more expensive.

C) Rising Energy Ambitions: As Europe's climate goals have grown more ambitious, so too have the requirements for the project, further increasing its complexity and cost.

Energy Minister Tinne Van der Straeten has acknowledged these challenges and has created a joint task force with Elia and the Electricity and Gas Regulatory Commission (CREG) to monitor and contain costs. Additionally, an audit of the design and costs is currently underway, with Elia expected to finalize the island’s new design in the first quarter of 2025.

Impacts on Consumers and Businesses

The rising costs of the Princess Elisabeth Island have significant implications for Belgian households and businesses. The high-voltage grid operator Elia funds its projects through investments that are passed on to consumers via energy tariffs. These tariffs are already set to rise from January 1, 2025, with average households paying an extra €82 per year, while large companies will face additional annual costs of €1 million. If the project's costs continue to escalate, these figures could rise further, placing additional financial strain on consumers and energy-intensive industries.

Regulator CREG has expressed concerns about the cost increases, noting that it warned the energy ministry about potential overruns as early as May 2024. It is closely monitoring the situation to ensure that the project’s costs do not unduly burden consumers.

Broader Implications for International Collaboration

The North Sea energy island is intended to be part of a larger international network of wind farms, connecting Belgium with other countries in the region. This collaboration aims to enhance energy security and resilience by allowing nations to share wind-generated electricity. However, the escalating costs are creating uncertainties about the project's feasibility. For example, Denmark has put its own plans for a similar energy island on hold, and the undersea cable that would connect Danish wind farms to the Princess Elisabeth Island is also delayed.

Despite these challenges, proponents of the project argue that the long-term benefits of the energy island outweigh the initial investment. By facilitating renewable energy generation and transmission, the island could help reduce dependence on fossil fuels and contribute to achieving net-zero climate goals.

Leadership Changes at Elia

The cost concerns come at a time of leadership changes within Elia. Bernard Gustin, who has served as chair of the Elia Group since 2017, will assume the role of CEO starting January 15, 2025. Gustin has expressed concerns about the rising costs but has also emphasized the need to focus on the long-term benefits of the project. He noted that while the current cost increases are significant, failing to invest in the island could lead to regrets in the future.

Gustin also highlighted Elia's ambitions to expand its activities internationally, particularly in the United States, where the energy transition presents significant opportunities. He aims to leverage Elia's expertise in renewable energy infrastructure to establish a stronger presence in developing markets.

Next Steps

The final cost of the Princess Elisabeth Island will depend on the outcome of ongoing tenders for electrical installations and the results of the cost audit. The tenders have faced calls for postponement from Febeliec, the federation of large industrial power consumers, due to the rising expenses. By the end of 2025, Elia and its partners aim to finalize the project’s budget and move forward with construction.

While the cost overruns have raised concerns, the project remains a critical component of Belgium’s energy transition strategy. Its successful completion could serve as a model for other countries looking to harness offshore wind energy and build interconnected energy networks in the face of growing climate challenges.
