Wind measurement campaign now even more efficient!

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.

Background

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.

Pondera member of DeepWind cluster

Pondera is expanding its business to Scotland by entering into the DeepWind cluster. This coincides with the start of the close cooperation of Pondera and Pronewable, where Matthias Haag is project director of Neart na Gaoithe, and forms a ‘flying start’ of Pondera’s Scottish operations.

The push for closer engagement in the Scottish and other UK offshore developments is a direct consequence of the collaboration with Oldbaum Services, located in Scotland and a long term partner. Pondera is currently focussing on expanding its turbine & wind resource testing services and is keen to demonstrate its unique knowledge and experience based on over 10 years of Dutch offshore developments, as well as its knowledge as launching customer of the Haliade-X turbine, suggested to be a key workhorse for many future UK projects.

Applications for SDE+ Autumn 2019 well exceed budget

The SDE+ (Stimulation of Sustainable Energy Production) is an operating subsidy for the production of renewable energy in the Netherlands, which covers the price difference between cost price of renewable energy and its market price. For technologies such as wind and solar energy, the subsidy is granted for a period of 15 years.

Between the 29th of October and the 14th of November of 2019, renewable energy projects were able to apply for subsidy during the Autumn edition of the SDE+. The edition required a mandatory proof of consent from the regional grid operator which demonstrated that the local electricity grid was able to transport the project’s intended power production (‘transmission capacity indication’). Many projects were unable to file a complete SDE+ application due to this demand. Despite this new requirement, the total amount of applications for the SDE+ subsidy greatly exceeded the available budget.

In our previous news item regarding the SDE+, we expected that the available budget of 5 billion EUR was likely going to be exceeded. However, we didn’t anticipate that the total amount of applications during the autumn edition would total 9 billion EUR of budget claims. This amount of subsidy applications is remarkable. It indicates that there are plenty of renewable energy projects waiting to be realised in the Netherlands.

Additional SDE+ Spring edition in 2020

Early November 2019, the Minister of Economic and Climate Affairs announced an additional SDE+ edition in the Spring of 2020. This edition will be open for SDE+ applications from the 16th of March until the 2nd of April 2020. The set-up will be identical to the 2019 editions.  However, the maximum subsidy prices (base/phase prices) will be adjusted. The tables below show the new prices for onshore wind and solar PV, together with the provisional correction amount for 2020.

Solar PV, ≥ 1 MWp, rooftop mounted0.0790.0470.069
Solar PV, ≥ 1 MWp, soil mounted or aquatic based systems0.0740.0470.069

On December 19th 2019, the minister informed the House of Representatives (Tweede Kamer) about the extra SDE+ Spring edition in 2020. For this edition, a budget of 2 billion EUR will be made available. Considering the budget exceedance of previous Autumn edition, this budget will most likely not be sufficient to grant all SDE+ applications. Therefore, it is of the utmost importance to submit a correct and complete application. Furthermore, adjusting the height of the SDE+ Base amount for which you would like to apply could also impact the chances of receiving the grant.

Pondera has successfully applied for and supported the application of many renewable energy projects in the past, including during the previous SDE+ edition. We are available for all your enquiries regarding the SDE+ subsidy and the new SDE++ subsidy scheme which will launch in the autumn of 2020.
