In total, the German federal energy regulator, the Bundesnetzagentur (BNA), awarded 30 contracts for solar PV projects with a combined capacity of 203.7MW in the auction.聽
鈥淗istory shows that joint tenders as an instrument have failed," said聽Wolfram Axthelm, CEO of the BWE.
鈥淎lthough they are successful with regard to the pure electricity generation costs for the absolute cheapest technology, they neglect the effects on the overall system. Important energy-related questions are ignored.
鈥淭herefore, the experiment of joint tendering should be ended," he added.
The weighted average of successful bids decreased to聽鈧53.30/MWh from聽鈧54/MWh in the previous joint-technology tender in November 2019.
Contracts were awarded with values ranging from 鈧49.70/MWh to 鈧56.10/MWh - compared to 鈧48.80-57.40/MWh six months ago.
By comparison, in the most recent wind-only tender for which results are available, successful bid prices ranged between 鈧57.60/MWh and 鈧62/MWh, with a weighted average of 鈧61.80/MWh.
The next technology-specific onshore wind and solar tenders will be held on 1 June, with 900MW available for each energy source.
Solar PV projects have now secured all the capacity in each of Germany鈥檚 five joint onshore wind and solar auctions.
One wind developer bid in the聽second onshore wind-solar PV tender聽in November 2018 but was unsuccessful. No wind developers entered the other four tenders.
Successful developers and projects in the latest technology-neutral tender have not been published online.聽
Normally, the publication would start the timeline to project deadlines. But the BNA opted not to do this to give developers more time during the coronavirus pandemic, the agency explained.
It will announce winners 鈥渁fter the situation has calmed down鈥, the BNA added.
