Several components go into the retail gas price that households pay to gas suppliers.
- Energy procurement and supply costs, plus the supplier's margin (i. e. the amount set through market competition)
- Regulated network tariffs (which may include charges for meter operation, metering and billing) that must be paid to the grid operator for supplying a particular customer
- (taxes and rights-of-way use fees)
State-introduced price components and network fees are set by legislators or regulators and thus fall outside the supplier's control. The supplier's procurement and supply costs, by contrast, are determined by market competition and can vary from one supplier to the next.
The from the Federal Network Agency (BNetzA) and the Bundeskartellamt (BKartA) puts the total average gas price at 6.68 cents/kWh for household customers, based on an annual gas consumption of 23.26 kWh. According to the Report, energy procurement and supply accounted for 3.51 ct/kWh on average (competition-based share).
Grid use fees vary across the country, because they depend on the costs in the specific grid area and the gas consumption in that area. According to the 2015 Monitoring Report, the nation-wide average was 1.45 ct/kWh.
