§ 19 Abs. 2 StromNEV

Information for our market partners for the settlement of the lost proceeds as well as the apportionment according to § 19 Abs. 2 StromNEV

Lost revenues and levy according to § 19 Abs. 2 StromNEV

Under Article 19 (2) of the Electricity Fees Regulation, final consumers may, under certain conditions, require an individual network charge from their network operator. The operators of transmission networks are obliged to reimburse lost revenues resulting from individual network charges to downstream operators of electricity distribution networks. The transmission system operators have to compensate these payments as well as their own lost revenue among themselves. The lost proceeds will be added to the network charges (§ 19 StromNEV surcharge) proportionately allocated to all final consumers.

The amount of the surcharge according to § 19 Abs. 2 StromNEV can be found on the common website of the German TSOs: www.netztransparenz.de

In the context of load balancing, the lost revenues of network operators from individual network charges pursuant to Section 19 (2) StromNEV must be reported to the regular transmission system operator and must be reported by 31.07. of the following year by an auditor.

In order to facilitate all parties involved in § 19 StromNEV testing, TenneT has prepared a model for the system for the auditor's certificate. The pattern can be downloaded here.

Please note that the corresponding annual statement of lost revenue acc. § 19 StromNEV must comply with the certified values.
