By August 1 of this year, the Federal Grid Agency had received 115 bids for solar systems on buildings and noise barriers. The Federal Network Agency announced the acceptance of 106 bids, covering a total volume of 201 megawatts. This means that the accepted bids are well below the 767 megawatts announced by the authorities.
The goals appear ambitious, especially as the federal government strives to fit as many rooftops as possible with solar energy systems. A tender was launched last year for 300 MW, and bids for 212 MW were received. The Federal Network Agency has announced that the next round of tenders will take place on December 1, 2022.
According to the Federal Network Agency (PDF), awards in this round of tenders are distributed regionally in a generally balanced manner, with projects awarded in 14 federal states. Most of the 52 contracts went to projects in North Rhine-Westphalia, followed by 15 in Brandenburg and 14 in Saxony-Anhalt.
Covered highways
Since the Renewable Energy Sources Act (EEG), which was amended at the beginning of 2021, all single-pot solar systems are no longer considered in tenders, and building systems and noise protection walls are being tendered separately from open space systems and other structural structures. systems. In Germany, those who want to build a photovoltaic system with a capacity of at least 750 kW and want to pay for their solar energy must participate in such a tender in “Part Two”.
In Switzerland, the government there, the Bundesrat, recently decided to make areas along national roads available to renewable energies free of charge from October 1, 2022. Concrete tests are also being conducted there to cover highways with solar panels. In Germany, this should be tested in the Hegau-Ost service area on the A 81 in Baden-Württemberg.
