Senior figures in Chancellor Angela Merkel’s governing coalition have agreed a deal to finally meet a commitment made earlier this year to hold special wind and solar tenders designed to bring Germany closer to its 2020 climate targets.

But the compromise now reached will see the additional capacity stretched into 2021, in order to ease possible grid bottlenecks.

Instead of tendering off 2GW each of wind and PV in 2019 and 2020 as promised during coalition talks earlier this year, the Christian Democrats (CDU), their Bavarian allies from the Christian Social Union (CSU) and the Social Democrats (SPD) have agreed to hold additional 1GW auctions each for onshore wind and solar in 2019, then 1.4GW
