## Summary

The Celtic Sea Floating Offshore Wind Leasing Round 5 ("Round 5") is a services concession contract initiated by The Crown Estate, a public corporation based in London, United Kingdom. This procurement process involves the grant of new seabed rights to developers for the development of floating wind farms with a maximum energy generation capacity of 4.5GW. The procurement stage includes a pre-qualification questionnaire phase with a submission deadline of 18th April 2024.

This tender presents opportunities for businesses in the construction-related services industry, particularly those involved in wind turbines, offshore mooring work, and turbine installations. Suppliers are required to participate via The Crown Estate's e-tendering portal and will be evaluated based on set criteria detailed in procurement documents. Successful suppliers will be awarded agreements for lease for the development of floating offshore wind farms in specific project areas within the Celtic Sea, fostering growth and innovation in the renewable energy sector.

## Notice

This is a services concession contract. The contracts which The Crown Estate expects to enter into as a result of the Celtic Sea Floating Offshore Wind Leasing Round 5 ("Round 5") will grant new seabed rights to developers for the development of new floating wind farms within three project development areas, each of which has a maximum potential energy generation capacity of 1.5GW (meaning a combined maximum potential energy generation capacity of 4.5GW across all 3 project development areas). These rights will be governed by three separate 'agreements for lease', which The Crown Estate intends to award to three different successful suppliers through a competitive tender process - one for each of the three project development areas. Holders of the agreements for lease will acquire the rights necessary to develop floating offshore wind farms in the relevant project development areas and will have the option to enter into leases with The Crown Estate for the construction and operation of these wind farms for the purposes of the generation, transmission and sale of electricity (or other forms of energy, where permitted), subject to the satisfaction of certain conditions detailed in the agreements for lease.
