Periodic Reporting for period 1 - ReaLCoE (Next Generation 12+MW Rated, Robust, Reliable and Large Offshore Wind Energy Converters for Clean, Low Cost and Competitive Electricity)
Reporting period: 2018-05-01 to 2022-02-28
Today, only less than 30% of the cost for electricity from large offshore wind energy converters incur from the turbine itself. ReaLCoE work to optimise innovation across the whole value chain; from initial turbine design to equipment handling in the port, to testing, financing installation and the final customer to substantially reduce the Levelised Cost of Electricity (LCoE) of offshore wind.
The consortium has brought together some of Europe’s experienced actors in both on- and offshore wind energy to demonstrate a 12+MW WEC. After a period of 13 month, the implementing OEM suffered insolvency and was substituted by GE, with DTU taking the coordination role for the project, with it’s aim of jointly contributing to the development and consolidation of a competitive market of offshore wind energy in the 12+MW turbine class.
We are confident that ReaLCoE will have a global impact on offshore wind energy market, reinforcing Europe’s technological leadership and bringing growth and job opportunities to the industrial base. Not only in the wind energy sector through the manufacturing, installation and operation of 12+MW WEC in a competitive environment; but also through the provision of cheap, clean energy across an integrated system of renewables. This paves the way for a turbine generation with rated capacities of 12+MW and triggers hundreds of millions in investment into the European clean tech sector.
After Senvion filed insolvency in 2019, the ReaLCoE project was suspended for a period of 29 month, after which the project was resumed with GE as the participating OEM.
The project re-started in October 2021 (M42) with the modified consortium. After resumption of the project with DTU as coordinator and GE as OEM, the process with determination of wind turbine concept and turbine characteristics ware repeated based on GE turbine data and taking the actual starting conditions for GE into account. This means that all previously submitted deliverables, including those related to the project management have been revised, updated and resubmitted.
During the last 6 months (Oct’21 to Apr’22), the consortium has started the collaboration, by signing the contract amendment, and updating the first key deliverables:
• WP1: Tech. specification of design basis completed (D1.1)
• WP2: Key assumptions MOL concepts (D2.1)
• WP3: Requirements verification matrix (D3.1)
• WP7: Insurance/bankability assessment (D7. 2)
• WP8: First communication material developed (D8.2)
• WP9: Project Manual (D9.1) Detailed Project Plan (D9.2) Risk Mitigation Plan (D9.3) Consortium agreement and IP management (D9.4)
The following milestones were reached as part of the restart of the consortium:
• M1 Governance
• M2 Site mapping
• M3 Validation of concept design
With GE taking over and after 29 month further general development, the basic conditions have also evolved, so that the starting point for the resumption is with the experience gained from the development of the GE 12+MW prototype turbine. This is assumed at this point to make our main objectives and specific objectives achievable with lower risk, even for the increased 14+ MW turbine in the revised project description.
The preliminary parameters of the next turbine generation of GE and the input from deliverable D1.1 are used as operational requirement in design and development of a new built jack-up installation vessel of JDN (Voltaire). The work has provided sufficient technical input to determine the operational limits for WEC logistic and installation in deliverable D2.1 “Key Assumptions MOL Concepts”. The provided data in D2.1 will be used by other project members as essential input for the modelling and optimization in design, fabrication, logistic and installation methods of next generation of WEC’s.
