Mercedes: Wind power for the EQC

Good for the operators, even better for Mercedes: When the first wind turbines from the EEG subsidy fall, the Stuttgart-based carmaker takes the power for its electric model EQC. The batteries will also be manufactured with wind power in the future.

The discussion about the CO2 emissions of electric cars is in full swing, as it ends Mercedes Benz in its own right again: The power for the in-house electric hope EQC comes in future directly from the wind turbine.
The background: With the end of the EEG subsidy, many operators of wind turbines conclude so-called Power Purchase Agreements, PPA for short . With these operators and pantographs agree on a fixed price and a long term. And Mercedes Benz Cars is one of the pioneers here.
The direct marketer Statkraft will sell the power of six community wind farms with 46 megawatts of total output to the Swabians, both announced in December. The factory in Bremen, where the EQC is manufactured, then runs on wind power. Likewise the battery location Kamenz of the Daimler subsidiary German Accumotive.

PPA prevail

Such new PPAs are not worthwhile for new systems. With about six cents subsidy worth the EEG trade. But experts assume that the transition begins slowly. Such subsidies, as they have enjoyed the now falling from the funding facilities, there is no longer.
Especially green electricity providers and large consumers are interested in the old systems, here there is finally cheap green electricity with proof of origin.
Statkraft has signed the first PPA contracts in Germany with six community wind farms (31 turbines in total) from Lower Saxony. The plants, with an installed capacity of 46 MW, went into operation in 1999 and 2001 and generate 74 GWh of electricity per year. This is one of "many cases in which a company without support is possible," said Carsten Poppinga, CEO of Statkraft in Germany. Mercedes Benz's electricity supplier Enovos from Luxembourg is responsible for the integration.
The power output from the wind turbine is staggered depending on the end of the EEG subsidy. For 2021, 33.1 million kWh are planned. In the years 2022 to 2024 it is expected to be 74 million kWh and in 2025 the contract provides for a delivery of 21.8 million kWh. "We want to supply all of our German plants with CO2-neutral energy by 2022. We are the first industrial company in Germany to use electricity from wind farms and thus ensure continued operation," explains Markus Schäfer, Member of the Board of Management Mercedes-Benz Cars, Production and Supply Chain.
This also calls the competition on the plan: "We are currently in discussion with other car manufacturers and other large industrial companies from different industries," says Statkraft spokeswoman Anne Joeken.
For Mercedes Benz in turn it is not the first PPA contract. With the project developer VSB, the automaker has signed a long-term contract for the purchase of wind energy for the plant in Jawor, Poland. From 2019, the Taczalin wind farm will deliver environmentally friendly energy to the entire high-tech factory with an installed capacity of 45.1 megawatts.
