Eneco purchases electricity Haliade-X prototype

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.

GE Haliade-X 12 MW supplies power

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

General information

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.

Declaration of no objections for Wind farm Bovenwind

On 23 September 2019, the Staphorst municipal council issued a declaration of no objection for the Bovenwind wind farm (previously Staphorst wind farm). This means that the developer of the park, Wij Duurzaam Staphorst (WDS) can now apply for the environmental permit. The wind farm consists of three wind turbines with a maximum rotor diameter of 150 metres.

The cooperative was established in response to the order from the province of Overijssel to the municipality of Staphorst to realise 12 MW of wind energy. The reason for establishing a cooperative for this was that if it had to be done, then the Staphorsters would rather do it themselves. And they succeeded.

In 2018 the young cooperative won the tender issued by the municipality for the development of three wind turbines in the municipality of Staphorst. The plan was considered by the advisory committee to be the best of five submitted plans. This was mainly due to it complying most closely with the municipality’s objective – to develop a 100% cooperative wind farm in which 100% of the returns flows back to the community.

Both the spatial framework, the framework with economic and financial participation, and the framework with process participation were assessed as excellent. The municipality was very satisfied with the proposal, which is ‘almost entirely cooperative’.

In order to provide certainty about the feasibility, the cooperative has entered into a partnership with the regional water board to help achieve part of its energy objectives.

The first step in the financial participation process has now been taken. From 20th August to 7th September 2019, residents of the municipality of Staphorst were able to take part in the participation survey in the Windpark Bovenwind. Almost 3.6 million euros in pre-registrations have been made. Registration will open in 2020.

Pondera supports the initiative of Wij Duurzaam Staphorst. For example, we supported the initiative to draw up the wind plan and its implementation by drafting an EIA and permit applications, and attended the various public and sounding board meetings in order to decide on things such as the number of turbines and dimensions. In addition, the focus has been on two principles, maximising the return for the village and minimising disturbance.

Pondera Consult supervises tender Nieuwleusen wind farm

In July 2019, Pondera drew up the tender documentation for Westenwind 1 B.V. for the design, construction and maintenance of two wind turbines in the vicinity of Nieuwleusen, The Netherlands. The two wind turbines have a combined maximum installed capacity of 9 MW. The project is another positive step towards the Province of Overijssel’s goal in achieving 85.5 MW of installed wind energy by 2021.

Invitation to tender

Pondera has announced an “Invitation to Tender” asking market parties to make an offer for the design, realization and maintenance of the wind farm. A distinction is made between the actual wind turbines, the crane stands, access roads, cabling and the transformer station. A special and challenging aspect is that both contract terms of the UAV-gc 2005 and Fidic Yellow are used. The offers will be assessed on both quality and price. The best market parties are expected to be selected for the wind farm before the end of the year. Once the wind turbines have been installed, Pondera will also take on contract management to ensure that everything proceeds according to the agreements made.

Pondera’s services

The support of tenders is a new service that Pondera has been offering to various customers for the past two years. Pondera can also assists in contracting, construction supervision, mediating and concluding PPAs (power contracts) and contract management of sustainable energy projects.

Blog: Largest wind turbines for low to medium wind speeds

Windy areas in countries that have well-developed wind energy markets, like the US, UK or Germany, are gradually being filled by wind farms. Renewable energy developers are therefore looking at opportunities to further develop wind farms in areas with low to medium wind speeds. Other regions with lower wind speeds are also being considered in new and upcoming markets like parts of West and Southern Asia, South-East Asia, Africa and other mid to lower latitude regions around the world.

Wind turbine manufacturers are attempting to cover this segment of the market by producing turbines that are specifically targeted to lower wind-speed sites and conditions. This is done by providing customers with higher turbine towers, combining existing generators with newer and longer turbine blades or even designing new generators from scratch. As wind turbines become more reliable, efficient and less costly, it is expected that even low wind-speed conditions in near-shore and offshore locations will also be further exploited in the future.

What does the wind energy industry consider low or medium wind-speed turbines? According to the IEC 61400-1: 2019 (editie 4.0) international standard regarding wind turbine design, when looking at annual average wind speeds, we find that wind turbines are categorized into four design classes: I (up to 10 m/s), II (up to 8.5 m/s), III (up to 7.5 m/s) and S (a site specific class). When turbulence intensity is considered, the following categories are added as suffixes to the classes:  A+ (a turbulence intensity up to 0.18),  A (up to 0.16), B (up to 0.14) and C (up to 0.12). Furthermore, the 10-min average wind speed with a 50 year return period in normal and typhoon conditions is also considered in the classification (Table 1). For example, class IA+ is then the most extreme wind turbine class outside of class S.

Still, there is no standardized definition of what constitutes “low” or “medium” wind speeds, which are basically qualitative descriptions. However, generally speaking, low wind-speed turbines are often considered as being in the classes up to IIIA (7.5 m/s), with medium wind speed turbines considered to be in the classes up to IIA (8.5 m/s). All other classes up to IA+ are generally considered to be high wind speed turbines.

Below, we look at the latest wind turbines designed for the low to medium-wind speed market. Each turbine mentioned on our list is offered by a different manufacturer in order to get a good view of what is or will become available in the near future. This list is not a full overview, but it does cover most of the major players in the wind turbine industry.

Wind turbine Siemens Gamesa SG 5.8-170

First on our list is the largest onshore dedicated wind turbine in the world in terms of rotor size as of writing. The SG 5.8-170, as obvious from its name, has a rotor diameter of 170 m, consisting of a three-stage gearbox and a 5.8 MW generator which is also the most powerful in the Siemens Gamesa onshore family of turbines. Hub heights are site specific and can range from 100 to 165 m according to the company’s website. The turbine is specifically recommended for low to medium wind speed conditions, with the first prototype expected to be built in the third quarter of 2020.

Wind turbine Vestas V162-5.6 MW

The V162 has the largest rotor size of all onshore Vestas wind turbines to date and is part of the newest EnVentus platform utilizing permanent magnet generators. The IEC S classed turbine is designed for low to medium wind sites but also suitable for higher wind speeds. Hub heights are expected to range between 119 and 166 m. As the first company to globally install 100 GW of wind turbines, Vestas aims to target the low to medium wind speed market with the EnVentus platform while continuing to develop also smaller turbines in the 3 MW range for the lower wind speed categories. The V162 is expected to roll out as a prototype in the middle of 2020.

Wind turbine GE 5.3-158

The GE 5.3-158 is part of the new onshore Cypress platform of turbines designed to be scalable over time in order to offer wider ranges in rated power and hub heights. The turbine was presented at the WindEurope Conference 2018 in Hamburg. It is currently GE’s largest and most powerful onshore wind turbine and builds on the previous GE 4.8-158 turbine design. The turbine was installed at ECN’s Wieringermeer test site, waar Pondera Consult assisted in the permitting, noise and shadow studies. Pondera was also responsible for the wind resource assessment and the energy yield calculation for the wind turbine’s Dutch subsidy application. Despite the 5.3-158 being the largest onshore GE wind turbine, it is still not GE’s largest. This prize goes to GE’s offshore Haliade-X with a rotor size of 220 m, making it currently the largest wind turbine in the world. The Haliade-X is being installed for prototype testing in the Port of Rotterdam’s Tweede Maasvlakte area by GE and Future Wind, a joint venture between Sif Holding and Pondera Development.

Wind turbine Goldwind GW155-3.3 MW

In October 2018, the largest Chinese wind turbine manufacturer Goldwind announced the development of the GW155-3.3 MW as part of the 3S platform. If built, it will become the largest Chinese manufactured onshore dedicated wind turbine in terms of rotor size. The permanent magnet direct-drive (PMDD) GW155-3.3 MW was announced together with the low wind-speed offshore GW168-6.45 MW turbine that is also adaptable for typhoon conditions. This clearly indicates Goldwind’s increased focus on the low wind-speed market segment, which is also very important for China being the largest wind energy market in the world.

Is bigger always better?

Whether bigger is always better really depends on the situation. In general, a large rotor swept area will convert more wind into energy. However there are many factors that need to be considered like the site specific conditions and wind climate, the costs of the turbine and its installation, the operation and maintenance costs, the turbine’s power curve and its overall capacity factor. All these factors play a role in the levelized cost of energy (LCOE). The “specific power”, which is the ratio between the rated power of the generator (also called the name plate capacity or nominal capacity) and the rotor swept area, is also an important factor. A very large rotor size combined with a smaller rated power would lower the specific power, reducing the amount of electricity generated. However, there are examples where lowering the specific power is purposely chosen in order to maximize the capacity factor, producing more stable and cheaper energy. In such cases, turbines like the Goldwind GW155-3.3MW or the Nordex N149 4.0 MW are sometimes more reliable options for developers than more powerful turbines.
