LCoE of future Dutch offshore wind farms

The Netherlands has the ambition to have multiple offshore windfarms operational by 2030 to fulfil climate agreements. The future wind farms will be constructed in sites located offshore of the North-Holland coast and north of the Wadden Isles. The ministry of Economic Affairs and Climate Policy of the Netherlands recently gained insight into the Levelized Cost of Energy (LCoE) of different variants for the wind farm sites considered for Hollandse Kust (west), Ten Noorden van de Waddeneilanden  and IJmuiden Ver.

BLIX Consultancy and Pondera Consult provided the study. Sites with varying energy density (in MW per km2) were considered. The LCoE was modelled per individual turbine with yield simulations and a financial model based on recent market prices.

Wikipedia: The levelized cost of electricity (LCOE) is the net present value of the unit-cost of electricity over the lifetime of a generating asset. It is often taken as a proxy for the average price that the generating asset must receive in a market to break even over its lifetime.

The results of this study were discussed by the ministry of Economic Affairs and Climate Policy and the Dutch wind industry. The tender of the first project in this study (Hollandse Kust (west)) is planned in 2020/2021.

Ben de Sonneville, researcher BLIX Consultancy: “We are proud to have contributed to optimizing the wind farm zones of the Dutch offshore wind roadmap 2030. We gained interesting new insights. The results reveal which site alternatives have lowest costs (LCoE) for wind farm development. Also, the study shows which factors (such as site orientation, water depth, wakes) influence the LCoE in each zone and which subareas are most economic for wind farm development.”

Wind in Vietnam: Dutch Opportunities

The opportunities for wind energy in Vietnam are looking very promising. Research by the World Bank estimates a total potential of 500 gigawatt, which is ten times Vietnam’s expected energy capacity in 2020. Areas with some of the best wind resources are located across the country’s long coastline or at sea. At the moment, Vietnam is mostly focused on onshore and nearshore wind energy.

Eric Arends, partner at Pondera Consult, conducted a baseline study earlier this year, on the opportunities for Dutch businesses and investors in Vietnam’s wind energy market. The research concluded that opportunities are plenty, even though the market in Vietnam is relatively in its early stages.

“European and Asian investors from for example South-Korea and China are keeping an eye  on Vietnam, especially because of the favourable wind conditions in the south-eastern part of the country. For offshore wind, not enough information is available on the wind climate and the seabed.”

In anticipation of a multiannual program, which connects Dutch knowledge with Vietnamese opportunities, Pondera Consult attended the Offshore roundtable on 23 November 2018. Eric Arends presented on the possibilities and future of offshore wind energy in Vietnam. He also discussed the opportunities for international, local and regional companies and investors. Eric recommended that the Vietnamese government develop a system for the controlled tender of offshore projects. The Dutch model, which has led to a large and fast reduction of costs, seems to be a good starting point.

“For the next ten years, both Vietnam and the Netherlands will see a period of strong renewable energy growth. Dutch experience in integrating renewables  into the power grid will be of great value to Vietnam.”

-Eric Arends, Pondera Consult

Vietnam’s future

In response to the baseline study from earlier this year, Pondera Consult was also invited to give a presentation on Dutch experiences at the ‘Scientific Conference on Renewable Energy and the Operation of the Electricity System’, organised by the Vietnam Electricity Group (EVN) in collaboration with the Vietnam Electricity Association and ICASA.

By the end of November 2018, there were 126 planned renewable energy projects in Vietnam, with a total capacity of almost 13 GWp. Only a small share of that capacity so far consists of wind energy. One of the challenges for Vietnam is integrating all that energy into the national power grid.

According to Ngo son Hai, Deputy Director of EVN, Vietnam will experience local overloads because of these new projects. This is due to the non-synchronous nature with which the Vietnamese power grid has been developed. Besides overloads, the quality of the energy grid can be affected (reliability, balance, harmonic distortion, etc.).

These problems will have to be resolved if the share of wind energy in Vietnam is to grow. According to the ministry of Trade and Industry, the goal is to increase the installed wind energy capacity to 6 GW by 2030, which is 2.1% of Vietnam’s total electricity demand.

Pondera to attend Vietnam’s Offshore Roundtable

During Vietnam’s Offshore Wind Roundtable on November 22nd, Eric Arends, director of Pondera Consult, will discuss the potential and outlook for the offshore wind industry in Vietnam and the potential for local and regional offshore companies and investors to participate in this future market. This event will bring together senior executives from the offshore wind industry in Asia.

The wind energy potential in Vietnam is very high and preparations to develop certain areas for wind energy are in progress. The Netherlands is a front runner in the field of wind energy with Dutch companies contributing to the majority of offshore and nearshore wind farms throughout the world. In the Netherlands, parties are looking with great interest at the renewable energy policy plans and wind energy development in Vietnam. In 2017, Pondera Consult was asked by the Dutch government (Netherlands Enterprise Agency, RVO) to carry out a study on the opportunities to contribute to wind energy development in Vietnam.

Renewable hybrid energy systems tourism industry

There is a high demand for affordable and reliable energy in the Indonesian tourism industry. The increase in energy price, the unreliable electricity supply and the trend towards sustainable tourism call for urgent action.

Tourists are increasingly aware of the impact their holidays have on the environment and are taking this issue more into account when booking their holidays. Yet, they wish to keep the high level of comfort they desire and are used to. At the same time, hotel and resort owners and managers are confronted with the increasing impact of energy consumption on their business profitability as well as on the image of their hotels. This is why affordable, reliable and sustainable energy is of great interest for large holiday resorts and hotels, as their electricity consumption is high and not easily reduced.

Pondera South East Asia can help businesses to resolve these problems. We have extensive technical knowledge to design sustainable and reliable energy production systems. We can design and calculate both on-grid and off-grid solutions consisting of several renewable energy production systems (mainly wind and sun) which eventually, combined with battery storage systems, form a reliable hybrid system with high availability of sustainable energy.

Various calculations of business cases carried out by Pondera South East Asia show that a hybrid sustainable energy supply can be a cost effective alternative to the current energy supply for large resorts and hotels in remote areas. In some cases, a sustainable energy system is more cost effective than the existing electricity supply. This of course depends on a large number of factors, such as the amount of sun-hours, wind speeds, current electricity prices and the availability of suitable space for renewable energy systems.

Pondera can calculate your business case for increasing the sustainability of the energy supply of your company with hybrid (renewable) energy systems. A quick analysis of your business case is always free of charge, without any obligation. The result of this first analysis will be an overview of your current and future costs for energy. If the quick scan shows high potential for a sustainable solution for your energy supply, Pondera can also assist you in all steps necessary to realize the sustainable energy supply for your company.

Consortium will support by conducting WRA HKN

A consortium consisting of Oldbaum Services, Pondera Consult, Whiffle and Deltares will support the Netherlands Enterprise Agency ( by conducting a Wind Resource Assessment (WRA) for Wind Farm Zone Hollandse Kust (noord) (HKN). The quartet was awarded the contract, among others due to extensive prior experience both in Dutch and European offshore wind projects.

Uncertainty reduction

The WRA – a desk study on the wind climate in the area of future Wind Farm Zone HKN – is used as input for the modelling of wind farms and/or estimating the future energy production of a wind farm. The approach of the study has the goal of reducing the uncertainties in this wind energy project, which might lead to a reduction of costs.

Hollandse Kust (noord) zone, next to existing wind farms

In order to achieve the most accurate results possible, the consortium will use the latest, state-of-the-art measurements techniques and models. Data from metmasts and (floating) LiDARs (laser-based wind measurement devices) will be combined with already existing data from KNMI/Rijkswaterstaat monitoring stations. This allows the wind climate to be determined and verified.

1 million households

The Dutch government wants to achieve a 14% renewable energy share in 2020, growing to 16% in 2023. Wind energy is an important renewable energy source in the Netherlands.

Wind Farm Hollandse Kust (noord) Wind Farm Zone is one of the offshore Wind Farm Zones designated by the Dutch government, with a total power output of 700 MW. This Wind Farm Zone will be located 18.5 kilometres off the coast and will provide power to 1 million Dutch households. This Wind Farm Zone is one of the six new offshore Wind Farm Zones which will be developed in the Netherlands.

Demand for wind measurement services quickly increasing

The demand for wind measurement services is increasing due to the growth and maturing of the wind energy market. Accurate wind resource assessments help in determining the right locations for wind turbines. Extensive knowledge of the local wind climate allows for a more precise wind farm layout design which is reflected in the final energy production. Wind resource assessments are also demanded by investors and wind energy financiers. The reduction of the uncertainty of energy yield estimations allows banks to finance wind energy projects on more favourable terms.

Next week, our wind measurement team will start 2 new wind measurement campaigns:

  • Wind Farm Pottendijk, where Pondera has also provided the Environmental Impact Assessment and permits;
  • Energy Park Daarle, where Pondera is also responsible for feasibility studies, permit applications, stakeholder management and project communication.

We are currently looking for new colleagues to expand our wind measurement team. If you are interested, here is a link to one of our job vacancies.

Pondera organizes Wind energy conference in Bali Indonesia

Pondera South East Asia will be organizing the WindDays in Indonesia on 7 and 8 October 2019.


“The Indonesians are ambitious with their renewable energy targets. We want to see if the experience from Europe and especially the Netherlands can help the Indonesians to build up their share of renewable energy. More specific we want to assess if we can assist the Indonesian government, state companies and private companies to develop wind farms and hybrid solutions with wind, solar and energy storage,” says Ester Bierens, WindDays trade fair manager in Bali. “We are organising the WindDays together with the Dutch Wind Energy Association (NWEA) and its Indonesian sister organization IWEA (Indonesian Wind Energy Association).”

Indonesia, the largest economy in Southeast Asia, has an attractive demographics and strong demand for energy. With one large, recently opened wind farm in Sulawesi of 75 MW, Indonesia is just at the beginning towards a more sustainable future. The countries’potential for wind energy is high. It has been calculated to have a total potential for onshore wind energy of 9.3 GW. The Indonesian government is aiming for 1.8 GW of installed wind capacity by 2025.

Do you want to be a pioneer in this development? If yes, the WindDays South East Asia will provide an excellent opportunity to explore this market and to take the first steps. View the leaflet of the WindDays here or visit the website of the WindDays South East Asia.

Pondera starts in Indonesia

Pioneering in Indonesia

Just like other countries Indonesia is beginning its own energy transition. The government has recently announced serious ambitions for this purpose. The archipelago has many natural resources available. And one of those sources is wind energy. Since 2016 we explore opportunities for cooperation and that has led to the opening of an office in Jakarta recently. Below you will find an (English) interview with our director in Jakarta.

For more informatie:

Let us introduce Mr. Chandra Soemitro, the Director of our new branche office Pondera South East Asia

Let’s start with yourself. What is your relation with renewable energy?

With my technical background, graduated at the University in Delft, I am responsible for a company in lightning protection systems named Zeus. My first encounter with Renewable Energy started around 10 years ago. At that time solar panels and hybrid systems consisting of small wind turbine and solar PV to generate electricity for LED lights were introduced commercially for the private customers. Later, the Indonesian government launched incentives and issued special regulations for the development of power plants based on renewable energy. Based on my technical background this development was and is very interesting for me. Especially the potential for wind energy has my interest. That is also the reason why, together with some business friends, we founded the Indonesian Wind Energy Association.

A new Pondera office in Indonesia. Why Indonesia?

Wind Energy in Indonesia is just in its starting phase and has quite a significant potential. Although I have to admit that the wind speed is lower compared to the Germany and Netherlands. Indonesia, as the largest economy in South east Asia, has attractive demographics and a rapidly increasing power demand.
This year Indonesia’s  first ever utility scale wind farm of 75 MW was opened by our President Joko Widodo. The Sidrap Wind Farm is currently the largest wind farm in South East Asia at this moment and is located in Sulawesi.
According to Indonesia’s Minister of Energy the total capacity of identified wind farm potential in Indonesia at this moment is round  1.8 GW.

What advantages does it have to operate from an office in Jakarta Indonesia?

The advantage to operate from Jakarta, is that  as  the largest country in South East Asia,  Jakarta is not only the capital of Indonesia, but also the headquarter of the South East Asian Countries Organization (ASEAN).
And with its 10 million inhabitants Jakarta faces enormous energy challenges, especially related to the transition to renewable energy sources. All relevant authorities to develop wind and solar projects around the country are based in Jakarta.
So, an office in Jakarta is geographically is important. From this city we can ideally serve our customers’ needs.

What will be the activities and services of PSEA?

From our Pondera South East Asia Jakarta Office we will be offering more or less the same services that are offered by our Dutch mother company Pondera Consult. In addition, Pondera South East Asia will be also focusing on initiating wind farm and potentially solar projects in this country.

What goal does PSEA have for the next 5 years?

The goal for the next 5 years is that Pondera South East Asia Office has to be securely settled in Jakarta with a professional team that has the competence to serve customers in South East Asian countries such as Singapore, Malaysia, Philippines, Vietnam, Cambodia, East Timor.

What are the first activities of the company?

We are currently working on a very interesting pioneering wind farm project on the island Sumba. I hope that Pondera will  successfully build a 3 MW Wind Farm on the island, including a energy storage facility and very interesting social community development that has been roles out already. We think that this could be seen as a good example for implementation at other islands with the similar conditions.

Beside this relatively small wind farm,  Pondera South East Asia currently initiating quite a number of wind farms projects with a much larger capacity.

What is your personal goal?

I would like to see that especially wind energy and solar energy play a significant role in the future energy mix of Indonesia. The challenge of Indonesia to fight climate change and city air pollution is enormous and I am enthusiastic, although our influence is perhaps small, to contribute in partly solving these challenges.

Highest court: wind farm Fryslân may be built

All the submitted objections against the permit applications or land-use planning for Wind Farm Fryslân were rejected. By this ruling The Council of State, the highest court in the Netherlands, has decided that the construction of Wind Farm Fryslân, in the Frisian part of the IJsselmeer at the height of Breezanddijk. Wind Farm Fryslân will consist of a cluster of 89 wind turbines, with a combined capacity of approximately 320 megawatts (MW). The the output of this wind farm equals the electricity consumption of 340.000 households. Construction will start in 2019. The expected start of operation is in 2021.

Pondera Consult has been involved from the earliest stage of development of the wind farm since 2008. After the preliminary feasibility studies, Pondera assisted during the drafting of the environmental impact assessment and took care of all the permit applications. Stakeholder engagement was a crucial part of Pondera’s role. Many stakeholders were involved such as official authorities but also inhabitants, nature, fishing sailing and tourism associations and others.

Pondera Consult congratulates the owners of Wind Farm Fryslân with their accomplishment.

Dutch perspective on New York’s ambitions wind energy

Last week Martijn ten Klooster (Pondera Consult) and Aaldert ten Veen (Stibbe) participated in the closed seminar organized by Sive, Paget & Riesel in New York, focusing on the ambitions of the state of New York regarding offshore wind energy. Governor Cuomo has set high ambitions. New York wants to have a 50% renewable energy supply by 2030. A significant share is to be supplied by 2.4 GW offshore wind farms, which means speed is of the essence. Last year, the first 30 MW of offshore wind energy was put into service. In 2019, over 800 MW is expected to be licensed.

The seminar was centered around discussing the most important points for the development of 2.4 GW. This was done in panel groups consisting of local and regional authorities, developers and consultants. The discussions focused on the power grid (interconnectors, ac/dc, public or private grid, etcetera.), the systematics of an environmental impact report (EIA), financing and supply chain, such as the availability of harbors. Martijn and Aaldert were asked to provide some insight into the lessons we have learned in Europe and in the Netherlands, by giving feedback on the panel discussions from a European perspective.

The participation of Dutch experts produced interesting discussions and contacts. It is clear that American governmental institutions and businesses are aware of Europe’s expertise and success in wind energy, indicating that now is the right time for New York to develop it’s off shore wind energy. However, knowledge and experience are lacking which means there are plenty of opportunities for the Netherlands.

The following were the most important strategical advices given by the Dutch experts:
• In order to anticipate rapid technical development of wind energy, EIA’s and permits need to be made as flexible as possible. Thus avoiding considering only the current state of technology.
• Another important point is the consideration of the accumulated effects of multiple future wind farms. This can lead to competing and conflicting interests between wind farms and the delay of procedures.
• A few months should be taken to create a thorough plan of action, both for the EIA and the general organization, to make sure the goals can be realistically achieved. Take for example the Dutch road map for offshore wind energy which is a good base for the development of future wind farms. An important point is to also highlight positive financial side effects of, for example, offshore power hubs.

If you have any questions about the opportunities for wind energy in New York or Pondera Consult’s activities, please contact Martijn ten Klooster ( +31 6 46 111 889).
