Components of
network access fees

Cost of network infrastructure

Provision and maintenance of power lines, switching stations, transformers and other transmission grid equipment (points of use ‘Extra high voltage network’ and ‘Transformation – EHV/HV’).

Cost of system services

Services pursuant to Section 5 of TransmissionCode 2007, which are necessary for transmission and distribution of electricity, and which ensure the safety and reliability of the power supply. These include primary control reserve and power, the provision of secondary control reserve and minute reserve, and operation of the transmission grid, including the point of use ‘Transformation – EHV/High voltage’.

Cost of covering transmission losses

The electrical losses that arise during transmission of electricity through the transmission grid.

Calculation of fees

The network access fees comprise an annual demand charge and a kilowatt hour rate. These depend on the annual period of utilisation, the network customer’s point of use and the optional use of other services. To see an explanation of the formula used to calculate fees, please visit the following link.

Please refer to the relevant price sheets for exact price information and a breakdown of invoices that are invoiced separately.

Further information on calculating network access fees

TransnetBW has calculated the network access fees, as of 1 January 2015, in accordance with Section 4 (3) Sentences 1-2 of the Incentive Regulation Ordinance (ARegV) of 29 October 2007.

When levying the network access fee, TransnetBW implements the Energy Industry Act (EnWG) of 7 July 2011, last amended 5 December 2012, and the ordinance issued on the basis of the EnWG. Furthermore, it implements the Combined Heat and Power Act (KWKG) of 19 March 2002, revised 25 August 2009 and last amended 28 July 2011, and the Renewable Energy Act (EEG) of 25 October 2008, last amended 17 August 2012.

Since 1 April 2002, TransnetBW has passed on the expenses incurred from the combined heat and power levies to end consumers who are directly connected to its transmission grid. Equalisation of the financial burden between TransnetBW and downstream grid operators, pursuant to KWKG 2009, is subject to separate provisions and not discussed here.

All prices given in the following price sheets do not include taxes, levies or any other payments TransnetBW is legally obliged to make, which directly or indirectly increase the cost of network utilisation. In these cases, TransnetBW invoices network users for the applicable amount and shows these payments separately on the invoice for network access fees.
