Abstract.
The TenneT 2GW Program represents one of the largest ongoing offshore transmission initiatives in Europe, comprising fourteen high-voltage direct current (HVDC) grid connection systems, each capable of transmitting 2 GW of renewable energy from offshore wind farms in the North Sea to consumers in Germany and the Netherlands. To enable a more efficient delivery of this portfolio, TenneT has introduced Systems Engineering (SE) practices based on ISO/IEC/IEEE 15288 with a systems approach and early verification. A systems engineering tool has been set up to support this effort.
This presentation examines the program through the perspectives of both employers, TenneT, and con-tractors, Hitachi Energy, a major HVDC supplier participating in six of the 2GW projects, systems engineers. The presentation draws on experiences from mainly four projects over the past three years, spanning tender and design phases. Attention is given to the interaction between TenneT’s program-level SE framework set up and the engineering, architectural, and delivery approaches of Hitachi Ener-gy to meet, support and benefit from this framework.
The presentation explores how SE objectives, structures, and information models established by the employer are interpreted and implemented within a contractor organization operating its own established engineering processes and system architectures. The findings highlight both opportunities and challenges associated with aligning differing architectural viewpoints, re-use requirements and design, and introducing early verifications. Benefits observed include increased reuse of contractual requirements enabling improved consistency between projects, enhanced traceability, and opportunities for design reuse that contribute to shortened engineering cycles and improved quality in later projects. Challenges include organizational changes, recovery and reconstruction of SE data, two different architectural reference systems, and the practical integration of customer-driven SE frameworks with con-tractor-specific ways of working.
The experiences presented provide insights into the ongoing adoption of Systems Engineering within the energy sector and the HVDC industry, emphasizing the importance of governance, architecture alignment, data quality, and collaboration between employer and contractor organizations. The presentation concludes with lessons learned, recommendations for large-scale infrastructure programs, and reflections on future developments in the application of Systems Engineering to complex energy transition projects.
Implementing Requirements Management in Tender projects, a
contractor’s perspective

Tendering for High Voltage Direct Current (HVDC) systems presents significant challenges for contractors. Invitations to Tender (ITT) and Requests for Quotation (RFQ) typically comprise contractual documentation of different types and structure, containing thousands of interrelated requirements. The requirements also reference a variety of internal, industry, customer-specific, and regulatory standards. Contractors must interpret, assess, price, and negotiate these requirements while considering technical, commercial, and legal constraints within a limited timeframe.
Schedule is challenging during both contract negotiations and in the transition from tender to project execution. Contractors are often given limited time to review final contract proposals, while requirements managers must rapid-ly establish a structured and quality-assured requirements baseline following a contract award.
To address these challenges, Hitachi Energy initiated the implementation of requirements management practices and tooling in tender projects, extending an approach previously introduced in project delivery. A pilot project was initiated to develop, implement, and evaluate processes, tool configurations, and operational practices. The project was conducted for one year and involved several tender projects. Based on project findings and tender projects feedback, the initial methodology was refined and adapted to the tendering environment. A decision to implement the refined solution in future tender projects was made at the end of the pilot.
