Vestas 15 MW prototype WTG produces first kWh
Denmark Wind power
Vestas has finalised installation of its V236-15.0 MW offshore WTG prototype at the Østerild National test centre for large wind turbines in Western Jutland, Denmark. On 30 December the prototype produced its first kWh of power and will now undergo an extensive test and verification programme to ensure reliability before full type certification and serial production begins.
“This is a great step forward … colleagues across Vestas have worked very hard and collaborated closely to ensure rapid progress in developing and assembling the V236-15.0 MW prototype … with this wind turbine we set new standards for technological innovation, industrialisation and scale across renewable energy to create a sustainable offshore wind
industry”, commented Anders Nielsen, Vestas Chief Technology Officer. The prototype development and assembly work has taken place across Vestas’ R&D and production sites in Denmark. The test programme for the generator, converter and grid system integration has already started at LORC test facility in Denmark.
With a swept area exceeding 43 000 m2 the V236-15.0 MW is expected to move the upper boundary of wind energy production to around 80 GWh/year per turbine, enough to displace more than 38 000 tonnes of CO2
every year.
The V236-15.0 MW is described as “globally applicable” and offers 65% higher annual energy production than the V174-9.5 MW. For a 900 MW wind park it
would increase production by 5% with 34 fewer turbines.
It is said to offer excellent partial-load production, and a capacity factor over 60% depending on site-specific conditions.
Net electricity production reduced – IEA
Worldwide Power production The most recent International Energy Agency ‘Monthly Electricity Statistics’ report, which includes October 2022 data, shows that for all OECD members total net electricity production amounted to 819.5 TWh in October 2022, down by 4.2% y-o-y compared to October 2021.
Electricity production from renewable sources slightly decreased by 0.4% y-o-y at 270.8 TWh. A higher production from solar (+9.4% y-o-y) and wind (+1.3% y-o-y) could not compensate the decrease observed for
hydro (-4.0% y-o-y). Overall, the share of renewables in the OECD electricity mix settled at 33.0%.
Nuclear electricity production dropped by 11.8% y-o-y at 129.9 TWh, continuing the downward trend observed during previous months. This decrease was mainly driven by OECD Europe (-23.9% y-o-y), followed by OECD Asia-Oceania (-6.1% y-o-y) and the OECD Americas (-2.0% y-o-y). Electricity production from combustible fuels amounted to 441.1 TWh, down by 4.0% compared to the same month last
year. Generation from natural gas remained fairly stable at 250.9 TWh (-0.9% y-o-y), while coal power production decreased to 147.0 TWh (-8.3% y-o-y), driven by a sharp decline in the OECD Americas (-12.9% y-o-y). Overall, the share of combustible fuels in the OECD electricity mix was 53.8%.
IEA’s Monthly Electricity Statistics feature electricity production and trade data for all OECD Member Countries and electricity production data for a selection of other economies.
DNV acquires AI-enabled Proxima Solutions
Norway Mergers & acquisitions DNV, the independent energy expert and assurance provider has strengthened its green power monitoring portfolio by acquiring Proxima Solutions, a prominent company in the provision of digital platforms for remote monitoring and asset management of renewable energy plants. Proxima Solutions offers a suite of artificial intelligence-based (AI) asset management software tools that enable renewable energy asset owners and managers to optimise operations, assess plant performance and maximise energy production. Its AI algorithms are intended to allow the early detection of component
anomalies and enable asset owners to implement preventative maintenance measures to avoid expensive machinery breakdowns and production losses. Headquartered in Berlin, Germany, Proxima operates a technology centre in Madrid, Spain, and is active in over eight target countries.
Proxima Solutions’ technical expertise and its Windlog and Energylog software tools will be merged with DNV’s GreenPowerMonitor business to strengthen its renewables advanced analytics capabilities and offer state-of-the-art monitoring – including real time updates, asset management and predictive

diagnostics services to renewable asset owners.
DNV’s Energy Transition Outlook forecasts, for the first time, that non-fossil energy will move slightly above 50% of the global energy mix by 2050. This is mainly because of the growing and greening of electricity production. Electricity production will more than double, and its share will grow from 19% to 36% of the global energy mix over the next 30 years. Solar PV and wind are already the cheapest forms of electricity in most locations and by 2050 they will grow 20-fold and 10-fold respectively and will dominate electricity production with 38% and 31% shares, respectively.
