Previous situation
Windpark Zijpe, the Netherlands, was the first commercial windpark in North-Holland, the Netherlands. Since 1992, the 9 Lagerwey windturbines are producing sustainable electricity.
The last years, three turbine were not producing anymore. After 25 years of spinning and producing electricity, these 3 turbines are at the end of their technical lifespan.
Counting from the north, 6 turbines (1992) are still spinning in the wind. Windturbine number 7 (counting from the north) was the first windturbine that was replaced in november 2019 for a new WES80 windturbine.

A community funded turbine, how does it work?
The WES turbine on Wind farm Zijpe (located in North-Holland) is realized by community participation project ‘Postalcode Rose Scheme’ (PCR). This ‘Incentive Programme’ makes it possible to replace an old, existing wind turbine by a new one, funded by private individuals, companies and foundations in the immediate vicinity (a specific postal code area).
The participants invest by purchasing a ‘wind share’ for which they receive an exemption on the energy tax on electricity for the next 15 years. This means that for each ‘kWh consumed’ one member will easily safe 50% on their annual energy bill. The Volksmolen cooperative consists of 56 members, the majority of whom are citizens plus a few companies that also decided to participate.
Transport and preparation
The different components of the turbine are pre-assembled in our workshop. After per-assembling, they are transported by a truck to the site. Our WES turbines fit in 40 feet containers, so they can be transported easily all over the world.
Installing the turbine
After unloading the transport, the different components will be prepared for lifting.
The tower parts are mounted to each other. After mounting, the internal cabling in the tower is prepared. After the erection, this cables will be mounted to the nacelle/ topbox and to the control cabinet.
The blades are mounted to the rotorhead on the ground. After mounting, the total nacelle with rotorhead and blades is lifted onto the tower en mounted at the tower.
After installation, the electrical parts will be connected to each other.
Forecast and production
The new WES wind turbine was forecasted to have an annual production of 180.000 kWh. Due to a number of very good wind months and a reliable and solid turbine technology, the new WES turbine has produced 215.000 kWh in 1 year.
After 2 years, the Volksmolen had produced 396.000 kWh. And, within 2,5 years, the Volksmolen reached 500.000 kWh of production.
Yearly environmental profit
Compared to generating electricity in a non-sustainable power plant, we yearly save more than 72 tons of CO2 with our Volksmolen Zijpe (72,343.59 kg CO2)!
For one entire production year, this is equal to the emissions of approximately 618,321 car kilometers
Per ‘wind share’, this amounts to approximately 103 kilograms of CO2, equal to more than 808 car kilometers with an emission of 117 grams/km (average emission of new cars in 2020).
