Early Framework Agreements (EFAs) are modular contracting structures that create stable, repeatable partnerships between utilities, suppliers and public authorities to accelerate grid expansion and modernization. They define consistent commercial, technical and governance terms across multiple projects, enabling earlier initiation of engineering, procurement and permitting activities while maintaining flexibility to adapt to system needs as they evolve.
Traditional project-by-project contracting often results in fragmented delivery, duplicated risk assessment and long procurement cycles. EFAs replace these short-cycle tenders with programmatic delivery models that allow standardized designs, clearer risk allocation and economies of scale. This supports more predictable scheduling, improves supply-chain visibility and enables faster build-out of transmission and distribution assets needed for renewable integration and electrification.
By introducing consistent delivery frameworks, EFAs help reduce total program costs, improve coordination among stakeholders and strengthen supply-chain resilience. They provide more predictable investment flows and clearer execution pathways for large-scale infrastructure programs.

Case Studies
TenneT, GE Vernova and Seatrium (2025), Germany
In December 2025, TenneT awarded a contract to a consortium comprising GE Vernova and Seatrium for the delivery of BalWin5, a 2.2 GW high-voltage direct current (HVDC) offshore grid connection designed to transmit electricity from wind farms in the German North Sea to the onshore grid at Bremen-Werderland. BalWin5 forms part of TenneT’s programme to expand offshore grid connections using a standardized 2 GW+ design. GE Vernova and Seatrium will also realize the 2 GW offshore grid connections of three Dutch TenneT projects to the onshore grid at Maasvlakte, Port of Rotterdam.
The award is the fourth project granted to the GE Vernova–Seatrium consortium under a five-year Framework Cooperation Agreement announced in March 2023, and the first under this framework for TenneT’s German 2 GW projects. The framework establishes common technical specifications, delivery models and commercial terms to support repeatable execution across multiple offshore grid connections. Under the contract, GE Vernova’s Electrification Systems business will deliver the complete HVDC technology, including the onshore and offshore converter stations and associated control and protection systems. Seatrium will design, build, transport and install the offshore converter platform, with fabrication planned at its facilities in Singapore and Batam. Construction is scheduled to commence in January 2026, with commissioning planned for 2032.
In parallel, TenneT has also put in place its largest framework arrangement for 2 GW offshore grid projects with Hitachi Energy and Larsen & Toubro and with Siemens Energy and Dragados, covering multiple HVDC converter stations across the North Sea. Together, these arrangements underline TenneT’s strategy of using early framework agreements and standardized designs to ensure supplier continuity, industrial scale-up and more predictable delivery of complex offshore transmission infrastructure.[1,2]
RTE (2024), France
In 2024, RTE, France's transmission system operator, contracted with five European suppliers – Prysmian, Nexans, NKT-SolidAl and Hellenic Cables – to secure high-voltage underground cable supplies through 2028. The nearly €1 billion (USD 1.15 billion as of Sep 2026) commitment covers the supply and installation of approximately 5,200 km of 90-400 kV cables. RTE's procurement strategy combines earlier demand anticipation, equipment standardization, larger purchasing volumes and framework contracts extended from five to eight years, with the aim of providing manufacturers with greater visibility over future demand.
The contracts reserve almost all French cable production capacity still available through 2028, including production of more than 1,700 km of cables in France. RTE reported that the greater demand visibility enabled Prysmian to invest in a new cable production line in Seine-et-Marne, illustrating how longer-term procurement commitments can support additional manufacturing capacity while securing strategic equipment for grid expansion.
