Aker Solutions' consultancy arm Entr and its wholly owned subsidiary Unitech Power Systems (a specialized, independent electrical engineering consultancy) have been awarded a contract by Nadara (renewable energy company) to conduct electrical infrastructure studies for the proposed 1.8 GW Bellrock Offshore Wind Farm, located 120 kilometres off the coast of Aberdeenshire, Scotland.

Contract Scope and Project Scale

Nadara, described as one of Europe's largest renewable-energy independent power producers, awarded the contract to the two companies to support the development of a high-level electrical infrastructure concept for Bellrock. The studies will cover the project's full electrical transmission system, spanning from offshore generation through to onshore grid connection.

The scope of work includes assessment of multiple transmission configurations as well as key elements of the electrical system, among them inter-array cabling, offshore and onshore substations, export cables, and grid integration.

The studies are designed to provide cost, schedule, and supply chain insights to support procurement planning, refine the project's electrical infrastructure concept, and reduce risk as Bellrock advances through future design, consenting, and investment milestones.

Division of Responsibilities Between the Two Firms

Under the contract, Entr and Unitech Power Systems will each bring distinct capabilities to the work. Entr will contribute project execution experience and real-world data to the study, while Unitech Power Systems will provide specialist electrical power engineering capability.

The intention is for the combination of these competencies to inform key investment decisions and establish what the companies describe as a robust foundation for future design, procurement, and delivery activities.

Dorthe Kirkeby, Vice President of Ocean and Wind at Entr, Aker Solutions, said that early definition of the transmission system is essential to managing cost, schedule, and technical risk on projects of the scale Bellrock represents.

"Through Entr and Unitech Power Systems, we will combine project execution insight with deep electrical power engineering expertise to help identify a practical, optimised and future-ready concept for Bellrock," Kirkeby said.

Kirkeby also noted that floating offshore wind has a major role to play in the energy transition, and that robust early-stage design will be key to enabling projects to move forward with confidence.

Nadara's Strategic Rationale

David Robertson, Portfolio Director at Nadara, framed the contract as a decision focused on getting technical choices right at an early and critical stage in Bellrock's development.

Robertson said the work will help Nadara assess the most robust and efficient transmission options, understand key cost and programme considerations, and build a stronger evidence base for future investment and procurement decisions.

"This study is about making the right technical decisions early. By working with Entr and Unitech Power Systems, we are bringing together strong offshore project experience and specialist electrical engineering capability at a critical stage in Bellrock's development," Robertson said.

Project Status and Consenting Progress

Bellrock's Wind Farm Development Area consent application was submitted in April 2026 and is currently progressing through the determination process. Further work is continuing across the project's offshore and onshore transmission infrastructure, covering engineering design, surveys, site selection, and stakeholder engagement.

Subject to the necessary consents and approvals, the project is expected to move through further transmission consenting, procurement preparation, and investment decision stages. The electrical concept study is intended to help refine the project's future transmission design as it advances through those stages.

Floating Wind Supply Chain Implications

The announcement highlights Bellrock's potential contribution beyond power generation, specifically its role in supporting the growth of the floating offshore wind supply chain. The project has been described as having the potential to make a significant contribution to Scotland and the UK's renewable power ambitions more broadly.

Floating offshore wind, which allows turbines to be installed in deeper waters where fixed-bottom foundations are not viable, represents an emerging segment of the offshore wind industry.

Scotland's deep waters make it a particularly relevant location for the technology, and projects of Bellrock's proposed scale are seen as significant steps in demonstrating the commercial viability of floating wind at large capacity.

About the Companies Involved

Entr is the consultancy arm of Aker Solutions, the Norwegian energy services company. Unitech Power Systems is a wholly owned subsidiary of Aker Solutions and brings specialist electrical power engineering capability to offshore energy projects.

Nadara is identified in the announcement as one of Europe's largest renewable-energy independent power producers and is the developer behind the Bellrock project.
