Construction on juwi's 1,000th wind turbine plant has commenced. The plant in Mohlis, Germany, was awarded to juwi by the country’s Federal Network Agency, in a tender process conducted last year.

With the construction of a recent four wind turbine project, juwi is one of the first German project developers to reach the mark of 1,000 wind turbines onshore.

The company states to have started laying the foundations and the park is scheduled to be commissioned in late summer.

The project marks an extraordinary milestone in the more than 22-year history of the manufacturer-independent project developer for wind and solar parks.

The commencement of construction also marks juwi’s successful arrival in the new Renewable Energy Sources Act (EEG) environment.

The Amendment of the EEG in 2014 aims to continue steady deployment of renewable energy in Germany in a cost efficient manner by integrating renewable energy solutions more to the market.

juwi's 1,000th wind turbine is a Vestas V136 turbine with a nominal output of 3.6MW, a hub height of 149 metres and a rotor diameter of 136 metres.

The total height is 217 metres. After commissioning, the four wind turbines will jointly generate around 50 million kilowatt hours of climate-friendly electricity.

This corresponds to the annual average energy consumption of more than 16,000 households, the company noted.

It further highlighted that the anniversary plant impressively documents the expertise of the juwi group in the planning, construction and operation of wind turbines as well as the technological advancement of wind energy over the past 20 years.

"In 1996, a 500-kilowatt-class wind turbine generated around one million kilowatt hours per year, and today we are creating around twelve times this much with the Mohlis plant. And the costs have fallen enormously, to now only about 5% per kWh," said juwi executive, Michael Class.

Wind energy market

According to the company’s MD, Greg Austin, in South Africa, wind energy has excellent potential and will increasingly be used in a hybrid mix.

Austin said: “We were successful in the awarding and financial closing of the 140MW Garob Wind Farm in Round 4 of REIPP.

There’s a very good complement between solar and wind in many parts of the country, particularly in the Northern Cape and Karoo. On a smaller scale, it offers a way for farmers to become independent of Eskom and of upward price pressures. Globally on a larger scale for grid connected renewable generators, we are increasingly seeing technology neutral tenders, where wind and solar can freely compete. Currently, in many markets the tariffs for the two technology types is on par.”

He continued: “When we assess a hybrid power project, if there’s a reasonable to good wind and PV resource, we typically see that financially it makes sense to plan PV first, wind second and only then do we consider storage. In other words, it often makes sense given current storage pricing to combine PV with wind before adding storage.”
