German gas storage operator Sefe sold less than a fifth of the capacity on offer at its Rehden site in an auction on Thursday — the first capacity sold at the site for the current storage year.
Sefe offered 5TWh and received bids in excess of this, but said it allocated only 900GWh, suggesting most bids were below its reserve price. German THE prices for delivery over the remainder of the summer, including the balance-of-May market, closed €2.08/MWh below the following winter price and €2.18/MWh below the first-quarter 2026 price on Wednesday.
The 900GWh was the first allocated space at the site for the current storage year, after one unsuccessful auction in January and one last week. The German government last month halved the mandatory fill level at the site to 45pc by 1 November.
Now there is capacity booked, there might be scope for Rehden not to be fully emptied, given that there is still 1.1TWh of gas in the 45TWh site. There is a two-month period during which capacity holders can withdraw their gas after the beginning of the storage year, and withdrawals have continued at the site since 1 April.
Sefe said it will publish further details on upcoming auctions for the capacity not yet marketed "in a timely manner".
Injections at Rehden would have to start by 17 August to meet the 45pc mandate, according to Argus calculations, factoring in 18.5 days of maintenance in October. Under the previous 90pc mandate, injections would have had to start before the end of May, taking Rehden's injection curve into account.
