Hitachi Energy has been named the preferred bidder for the design and construction of HVDC converter stations for the EGL3 project. This significant initiative is set to transform electricity transmission in the UK and is part of a larger £20 billion investment by SSEN Transmission to modernize Scotland’s electricity infrastructure. The Eastern Green Link 3 (EGL3) project includes a remarkable 680km HVDC subsea and underground cable which facilitates the transmission of up to 2GW of clean power from Longside in Aberdeenshire to Walpole in Norfolk. In this blog post, we'll examine the implications of this milestone, its impact on the energy sector, and what it means for the future of energy in the UK.
The Importance of the EGL3 Project
The EGL3 project represents the largest proposed HVDC transmission initiative in the UK. As the country moves toward a sustainable energy future, such projects are crucial for enhancing the capability of the national grid. The 680km of HVDC cable will not only enable efficient long-distance electricity transmission but will also help to ease network bottlenecks that have been a point of contention for years.
The converter stations play a pivotal role in this process. By converting electricity between AC and DC, these stations increase the efficiency of power transfer, which is particularly vital in a nation rich in renewable resources like wind and solar. This project is expected to generate enough power for approximately two million homes, showcasing the scale at which renewable energy can be integrated into the grid.

Hitachi Energy's Role
Being selected as the preferred bidder is a major milestone for Hitachi Energy. It not only underscores the company’s engineering and technological expertise but also aligns with the UK's Clean Power 2030 target. Hitachi Energy's broader vision is to create sustainable energy solutions that facilitate the transition to a low-carbon future.
The company's role in this project entails designing and building sophisticated converter stations essential for the HVDC framework. This involves cutting-edge technology that requires precision engineering and expert project management. The ability to navigate these complex requirements will be vital in ensuring timely delivery and efficient operation of the stations.

Planning and Construction Timeline
The EGL3 project is slated to unfold over several years. With planning applications scheduled for 2026 and construction expected to begin in 2029, there is a clear timeline for project managers and construction teams to consider. The objective is for the project to be completed by 2033.
This well-defined timeline allows procurement officers and estimators to develop efficient planning strategies. Understanding the landscape of procurement and resource allocation will be crucial for various stakeholders involved in the project. It is advisable for these professionals to remain informed about relevant regulations and best practices in order to optimize their strategies.
Impacts on the Energy Sector and Beyond
The implications of the EGL3 project extend beyond just electricity transmission. For construction managers, the scale and complexity of this project present numerous opportunities for innovation and growth within the sector. The investment in infrastructure creates jobs and stimulates the economy, highlighting the interconnectedness between energy and economic stability.
Moreover, the transition to an HVDC system addresses several critical issues related to energy security. By improving the transmission framework, the UK can reduce reliance on fossil fuels and enhance its energy independence. This, in turn, supports not only environmental goals but also political stability, making it a priority for stakeholders across the board.

Moving Forward: Key Considerations
As we look ahead, there are several key considerations for those involved in the EGL3 project and similar initiatives. Emphasis should be placed on sustainable practices throughout the construction process. Implementing eco-friendly materials and preserving local ecosystems can mitigate the environmental impact of significant infrastructure projects.
Furthermore, collaboration between construction companies, local governments, and regulatory bodies is essential. Open lines of communication will facilitate problem-solving and foster a cooperative work environment, reinforcing the project's success. Stakeholders are encouraged to engage in community outreach to address concerns and promote transparency in the development phases.
Investment in training and skill development for the workforce will also play a crucial role. As technology evolves, the demand for skilled professionals in energy and construction will increase. Companies should prioritize education and training programs to keep their teams up to date with the latest industry standards and innovations.
The Future of Energy in the UK
The success of the EGL3 project may serve as a blueprint for future infrastructure projects across the UK and beyond. By emphasizing efficient energy solutions, investing in cutting-edge technologies, and prioritizing sustainability, the energy sector can continue to evolve.
As major infrastructure projects come to life, stakeholders can glean insights from projects like EGL3. Successful implementation can help streamline processes for future endeavors while creating a more robust energy network. Additionally, the long-term benefits of such projects can lead to a greener and more resilient economy, setting an example for other countries.
With planning applications expected in 2026 and construction commencing in 2029, the EGL3 project symbolizes not just an advancement in technical capabilities but a step towards a sustainable energy future for the UK.
The completion and operation of the EGL3 project will represent a long-awaited shift in the UK energy landscape, contributing to the goals established for a clean and sustainable nation. By leveraging the expertise of companies like Hitachi Energy, stakeholders are working towards a more effective and green energy framework.
In summary, as the EGL3 project takes shape, stakeholders across the energy, construction, and public sectors should remain engaged in conversations about its benefits. Together, they can ensure that this pioneering initiative serves as a cornerstone for future energy projects in the UK.
