This morning 6am CEST our OpenEMS displayed a GridBuyPrice of 25.705 ct/kWh, see below screenshot:
The Entso-e transparency plattform reports a price of 11,997 ct/kWh for the time frame of 18/06/2026 04:30 - 18/06/2026 04:45 UTC. Our DSO is Netze BW and adds ancillary costs of 9,01 ct/kWh. So we end up with 21.007 ct, which is a difference of approx. 4.698 ct/kWh.
Can someone please give me a hint where this difference of 4.698 ct comes from?
