Conducting power curve verification offshore
DNV has been selected by the Iberdrola Group to perform power curve verification at the Bay of St. Brieuc offshore wind farm, employing advanced nacelle lidar technology.
Situated 16 km off Cap Fréhel in the Bay of St Brieuc in the Côtes-d’Armor district, the farm is notable for being the first large-scale offshore wind power installation in Brittany – a region renowned for its strong winds and high tides, which have historically shaped its landscape and economy – and the second in France dedicated to producing clean energy. Developed by Ailes Marines, a subsidiary of Iberdrola, the 62-turbine farm has been fully operational since May 2024. With a total installed capacity of 496 MW, the wind farm is expected to significantly enhance the region’s clean energy supply, covering 9% of the region’s total consumption. DNV’s power curve verification project encompasses the design, commissioning, and
execution of a power performance measurement (PPM) campaign for three turbines, along with the installation of all necessary equipment to ensure the campaign meets accreditation standards. Before deployment, the lidars will be calibrated at DNV’s testing facility in Germany to comply with the updated IEC 61400-50-3:2022 standard. This standard allows for the use of nacelle-mounted lidars (NML) in performance assessments, an area where DNV has extensive expertise. The power curve verification will enable Iberdrola to align actual energy production with initial projections, improving the accuracy of economic models for the wind farm. The initiative enhances operational efficiency and supports broader sustainable development goals. “DNV is one of the pioneers in power performance measurement using nacelle lidar technology. This project showcases our ability to leverage advanced technologies and adhere
to stringent industry standards in wind energy. We are dedicated to advancing safety and performance, setting industry benchmarks, and developing solutions to address the global energy transformation,” said Santiago Blanco, executive VP and regional director for Energy Systems at DNV.
The data from St Brieuc provided by DNV is expected to be essential to understanding and optimising performance of the wind asset, setting a benchmark for other future offshore wind projects.
PeroNova unveils ‘groundbreaking’ perovskite technology
PeroNova has announced its entrance into the renewable energy market by unveiling its ‘pioneering perovskite technologies’ aimed at revolutionising solar energy, space technology and the supply chain for perovskite production. PeroNova hopes to capitalise on significant opportunities arising in the renewable energy sector and space tech sector. Perovskite, noted for its efficiency in converting sunlight to electricity, offers a promising alternative to traditional silicon-based solar cells. The global building-integrated photovoltaics market was valued at $23.67 billion in 2023, driven by roof
installations, and showing high demand for perovskite technologies. Production is likely to be supported by opportunities in the space tech market, which worth $534 m and currently using the more expensive Gallium arsenide cells. PeroNova has achieved what are said to be significant enhancements in the stability and reliability of perovskite films, critical factors for commercial viability. The company will launch several pilot programmes in the USA later this year with space tech companies and real estate developers. Specifically, the latter collaboration is expected will bring large-scale implementation of
BIPV and agrivoltaics across the country. Dr Min Chen, co-founder, CEO and CTO of PeroNova, commented: “We are … privileged to have Dr Peter H. Diamandis join our advisory board, bringing a wealth of knowledge that will undoubtedly enrich our strategic direction as we navigate this pivotal phase.” Mr Diamandis is well known as the founder and executive chairman of the XPRIZE Foundation, which leads global large-scale incentive competitions, and Singularity University, a Silicon Valley graduate-level institution that counsels leaders on exponentially growing technologies.
Celeros to supply Sizewell C with nuclear pump packages
Celeros Flow Technology has secured multiple contracts to supply the safety-critical nuclear pump packages for Sizewell C, the UK’s newest nuclear power station, currently under construction. The pumps will be designed and manufactured by the company’s ClydeUnion Pumps brand at its nuclear-accredited facility in Annecy, France.
The 3.2 GW Sizewell C NPP is being constructed alongside the existing Sizewell B plant on the East Suffolk coast. It will avoid nine million tonnes of CO2
for every year of the
anticipated 60 years of operation, and may help kick-start net zero technologies such as hydrogen production and direct air capture.
ClydeUnion Pumps will be manufacturing numerous safety-critical pump packages for the power station. These include the pumps for the Emergency Feedwater System (ASG), which supplies the required rate of water to the steam generator’s secondary side if all the systems contributing to normal supply of the steam generators are unavailable; the Component Cooling Water System (RRI), which is designed to cool and transfer the heat load from various components and systems within the nuclear island during different operating conditions of the nuclear plant units; the Safety Injection System (LHSI and MHSI ), which stops the nuclear reactor and supplies it with a
constant source of water during a coolant loss incident; the Nuclear Island Vent/Drain System (RPE), which confines radioactive substances in the event of an accident by transferring contaminated fluids to the reactor building; and the Safety Chilled Water System (DEL ), which produces and distributes chilled water for HVAC systems.
Celeros’ involvement in the nuclear power market began with the first ever industrial scale nuclear power plant. Since then, they have been central to many major nuclear power programmes and their pumps and valves are installed in more than 65% of operational nuclear power plants globally.
