Cierco Energy has signed an agreement for lease with The Crown Estate, securing seabed rights for its Llŷr Wind floating offshore wind projects in the Celtic Sea. The agreement unlocks two 100 MW test and demonstration projects off the Pembrokeshire coast, among the first in the UK to trial next-generation floating wind technologies at scale. The company positions the projects as a launchpad for future gigawatt-scale developments, aiming to transform South West Wales into a hub for offshore engineering and supply chain growth.
Details of the Agreement
Cierco Energy has secured formal rights to develop in the Celtic Sea. It signed an agreement for lease with The Crown Estate. This agreement grants seabed rights for the Llŷr Wind projects. The projects are located off the Pembrokeshire coast in Wales. Securing seabed rights represents a foundational step for any offshore wind development.
The agreement unlocks two specific demonstration projects. Each is a 100 MW test and demonstration floating offshore wind project. Together they will trial next-generation offshore wind technologies at scale. This makes them among the first UK projects to do so. The test and demonstration focus distinguishes them from commercial-scale developments.
Purpose of the Demonstration Projects
The projects are designed to prove emerging floating wind technologies. Company leadership described them as vital stepping stones toward commercial deployment. They provide an opportunity to test world-leading offshore foundations. Mooring systems and dynamic cabling will also be trialled. This testing occurs before scaling up to full commercial developments.
Demonstration projects play a distinct role in the development pipeline. They allow technologies to be proven under real operating conditions. Company leadership noted that such projects are where supply chains form. They are also where investor confidence is built through demonstrated performance. This positions the projects as a bridge between innovation and commercial deployment.

Significance for Floating Wind
The projects contribute to advancing floating offshore wind technology. Floating wind enables development in deeper waters than fixed foundations allow. The Celtic Sea presents a significant opportunity for this technology. It offers potential to unlock new sources of clean energy through floating wind. This makes the region strategically important for the sector's growth.
The Crown Estate framed the projects within a broader technological effort. Projects such as Llŷr help advance the technologies needed for future offshore wind. They also develop the skills and supply chains the sector requires. This supports the next generation of offshore wind development. The agreement for lease is described as an important milestone in this progression.
Economic Ambitions for Wales
The projects carry significant economic aspirations for the region. The company positions them as establishing a launchpad for gigawatt-scale developments. This aims to position Wales as a global leader in offshore wind innovation. The goal is to transform South West Wales into a powerhouse for offshore engineering. Supply chain advancement forms a central part of this vision.
The anticipated benefits extend to jobs and regional standing. The projects are expected to generate high-skilled jobs in the region. They would strengthen South West Wales's position on the world energy map. Company leadership described the potential for a world-class industrial ecosystem. This would span offshore fabrication, engineering, advanced manufacturing and technology exports.
Collaboration and Delivery
Successful delivery depends on engagement with multiple stakeholders. The company committed to working closely with local communities. It also aims to collaborate with supply chain partners and government stakeholders. This collaborative approach is intended to deliver on the project's vision. Company leadership described the agreement as a defining moment for the Celtic Sea's green energy future.
The projects are framed as catalysts for wider industrial development. Company leadership suggested today's innovation hub could become tomorrow's manufacturing cluster. The Crown Estate emphasised driving economic growth alongside clean energy. It highlighted long-term benefits for Wales from the development. Together these ambitions link the projects to both energy and economic goals.
