At the location of a future wind farm, measurements are often taken with a meteorological measuring mast or LiDAR to determine the local wind climate, which is necessary for financing and engineering of the planned wind farm. Given that measurement campaigns only last a year, or even less, it is necessary to compare the data with a long-term meteorological data set. During the short-term measurement campaign, for example, the wind speed may be slightly higher than the average for that time of the year. We often use ERA5 data from the preceding 15 years for this comparison. A disadvantage of the ERA5 data (and most other comparable data sets) is that, due to the time required for the verification process, the data is only available 2-3 months after the date. This results in a considerable delay in the delivery of the wind reports, which is certainly undesirable if the project is approaching financial close.
ERA5T, available since the beginning of December 2019, changes this by making the data available within five days. This allows measurement campaigns to be analysed faster, and it also makes them more flexible. For example, Pondera can now decide during the campaign whether the desired minimum uncertainty has been achieved and thereby advise whether the campaign can be shortened. This reduces the costs of measurements and increases the speed. In this way Pondera helps to make wind energy more affordable and faster to realise.
The original ERA5 model is a weather model from ECMWF (European Centre for Medium-Range Weather Forecasts) and is based on historical weather data that models the weather around the world from 1979 to the present. In contrast to the ERA5 data, the ERA5T data from December 2019 has not yet been verified, but deviations from the final ERA5 data are very unlikely, according to ECMWF itself.
Eneco, Future Wind (a joint venture of Pondera Development and SIF Holding Nederland) and GE Renewable Energy announced today that Eneco will purchase all of the electricity generated by GE’s Haliade-X 12 MW prototype. The announcement was made during the inauguration ceremony for the prototype, that was recently installed at the port of Maasvlakte-Rotterdam (The Netherlands).
The prototype located at Maasvlakte Rotterdam in the Netherlands, has just set a new world record this past weekend by being the first wind turbine ever to generate 288 MWh of clean energy in 24 hours, enough to power 30,000 households in the region. Over the next five years period, the Haliade-X prototype will undergo a series of tests to validate the turbine’s power curve, loads, grid performance and reliability. The tests will also allow the company to validate operational procedures for installation and services teams. The testing will allow GE Renewable Energy to obtain a Type Certificate for the Haliade-X in 2020, keeping the company on track to commercialize the turbine by 2021.
The GE Haliade-X 12 MW has delivered its very first kilowatt hours. The prototype of the world’s most powerful offshore wind turbine has now entered its test phase on the Maasvlakte in Rotterdam. The data collected during this phase will be used to obtain the required certificate in 2020. Subsequently, the serial production of the largest and most powerful wind turbine can start.
Key figures for the Haliade-X 12 MW
Capacity: 12 MW
Rotor diameter: 220 m
Blade length: 107 m
Hub height: 150 m
Tip height: 260 m
Wind turbine swept area: 38,000 m2
Annual energy yield: approx. 67 GWh
Pondera Development and SIF Holding, together with GE Renewable Energy, are developing the Haliade-X on the Maasvlakte 2 in Rotterdam. The development of the innovative Haliade-X project in Rotterdam has been made possible thanks to Pondera’s extensive knowledge and many years of experience in Dutch wind energy legislation and regulatory policy. The increase in size and scale of (offshore) wind turbines is an important step in generating more sustainable energy, accelerating the energy transition and thereby limiting the effects of climate change.
The offshore wind turbine prototype will be installed onshore in order to ease access for testing and monitoring purposes. This will also allow GE to collect the data needed to obtain the Type Certificate, a key step in commercializing the Haliade-X.
The Haliade-X can generate 67 GWh of electricity annually. That is enough power for 16,000 European households and thus saves 42 megatons of CO2. In the fall of 2019, the Haliade-X will generate renewable energy on the SIF site on the Maasvlakte.
On the 9th of September, seven permit applications were submitted for constructing Wind farm Wieringermeer at the municipality of Hollands Kroon. The wind farm, located in the Wieringermeer polder, will consists of 102 wind turbines which will replace individual wind turbines in this area. The wind farm was initiated by Nuon, ECN and Wind collective Wieringermeer, a local collective of farmers and wind-turbine owners.
Pondera Consult prepared the environmental impact assessment and managed the permit application process.
The draft permits will be up for public consultation by the end of this year.
