RVO publishes progress report on onshore wind in the Netherlands between 2014-2020

This week, Netherlands Enterprise Agency (RVO) published the so called onshore wind monitor (Monitor Wind op Land) 2014-2020. This report provides an overview of the main developments of seven years of onshore wind energy in the Netherlands.

Since 2014, RVO, by order of the Ministry of Economic Affairs and Climate Change, has annually presented the progress of onshore wind energy in the onshore wind monitor. The monitor shows both the development of the construction of new wind turbines and innovations.

Total installed capacity and number of wind turbines

In 2014, renewable energy accounted for 10% of total electricity consumption. Onshore wind accounted for 4.6% of this share. In 2020, this share has grown to 8.8 %. According to the report, the total number of installed onshore wind turbines increased from 1,954 in 2014 to 2,112 in 2020. The installed capacity increased from 2,579 MW to 4,177 MW over the same period.

This means that the target of 6,000 MW in 2020, as agreed in the Energy Agreement, has not been met as expected. On 31 December 2020, 2,783 MW of capacity is under construction. According to forecasts, the target of 6,000 MW will be met in 2023 (6,665 MW).

Development in size and yield

Since 2014, wind turbines have become bigger, with larger rotor diameters. The tip height increased from 144 metres to 187 metres, the rotor diameter from 94 metres to 123 metres, while the capacity grew from 3 MW to 3.8 MW in the period from 2014 to 2020.

As a result of this development, the electricity production per wind turbine increased significantly: from 8.1 GWh to 12.9 GWh in 2020.

Cost price of electricity from wind energy

Between 2014 and 2020, the cost price of onshore wind energy fell by 42% from €89 to €52 per MWh. The drop in cost price has meant that less subsidy is needed to operate onshore wind energy profitably.

Innovations

Innovations have been implemented in the area of nature protection, such as bird detection radar systems, noise reduction (by using finlets/’owl feathers’ on the blades) and aviation lighting. For the latter, two systems have been developed. The first system ensures that the lights only burn brightly when the weather and visibility are poor. At night, the lights may also be fixed instead of blinking. Work is also being done to make approach detection legally possible. This means that lights will only switch on when aircraft are detected in the vicinity of the wind turbine.

Type of developers

In addition to commercial developers, parties such as energy cooperatives and farmers are increasingly becoming involved in the development of wind farms. In the past seven years, the cooperative wind energy capacity has increased from 71 MW in 2014 to 230 MW in 2020.
