Oh boy this will be a tricky one, at least for Sweden. While the taxes and such are the same for the whole country the fees the utility takes varies a lot. This is further complicated by the fact you can and most do have to electricity utilities for each home. One is responsible for the last mile infrastructure and takes a fee for that, the other is the one you actually buy the electricity from. Both of these take out a fee and for the utility that owns the infrastructure this usually varies per municipal or city at the very least. The only way I see this working if the users can input some of the data themselves in the settings and we then calculate the price locally based on known factors like the day ahead price and taxes together with variable factors like utility fees. |

You can get annual statistics for each European country here. I am assuming some taxes are per kWh (network costs, renewable premium...), and some are per € (VAT), so if you know the wholesale market price, you would be able to determine the rest dynamically? |

For Germany, Zeit has a great overview for the current price for new end customer contracts. They apparently use data from the German comparison portal verivox |

I have source for Czechia as the network operator provides them, however, it's temporarily unusable as there's a not closer explained bug in the data provided. I'll add it if the CZ.pay parser will be approved when this is available again (raw electricity). |

In Ontario there are two different basic rateplans to choose from (time-of-use and flat-per-kWh): https://www.oeb.ca/consumer-information-and-protection/electricity-rates. Delivery fees vary by city or region (by operator of local distribution and billing), for example I pay (nominally) 40.70 CAD per 30 days, while my relatives pay 29.77 CAD per month. There are also various extra fees and credits. This is a recent bill for a 30 day period: Not sure how you would process or display this... |

In the case of Spain, which I'm familiar with, you can find the energy price with all charges included (transmission+distribution costs, ancillary services, utility margin, support to renewables, and the adjustment due to the current gas cap) at https://www.esios.ree.es/en/pvpc. However, these prices do not include taxes, which currently amount to 5.53% of the electricity price (27.19% before the measures taken by the government because of the war in Ukraine). The final electricity bill also includes charges on the rated or maximum allowable power of the household but, since the escalation of prices, energy comprises the majority of the costs. You also need to know that only ~50% of the consumers in Spain pay the variable price or PVPC. The other 50% pay a fixed rate set by the utility company, though it is heavily based on the variable price. |

For Italy: Another useful source is Government GME website. Also cumulative historical data here: PUN, prices split by bidding areas, ... and even much more. |

Data sources for electricity price data
The inclusion of electricity price data for end consumers would be a large milestone for expanding Electricity Maps' data coverage. We need your help to identify potential open and free data sources that could enable that data to appear on Electricity Maps. 🙏
But doesn't Electricity Maps already show electricity prices?
Yes that's true! As you can see below on Fig. 1, Electricity Maps already displays electricity prices for some zones.
Figure 1: Example of Electricity Maps' price data for 24h
The price data shown is nevertheless not representative of what end consumers would actually pay for their consumption of electricity. That price corresponds to the day-ahead price for electricity. That is the price that is decided a day ahead in advance for a MWh of electricity. That price is decided on a market and corresponds to what producers would receive in exchange for injecting that amount of electricity on the grid.
For that electricity to reach end consumers, other parties and processes must be accounted for. These include for example transmission systems and distribution systems.
Decomposition of the price for end consumers
When actually accounting for everyhing that the end consumer must pay for to consume electricity we obtain something like what is displayed on Fig. 2.
Figure 2: Typical decomposition of an electricity bill in DK.
This clearly shows that the price shown above, that corresponds to the electricity itself only represents around 40% (in DK) of the entire bill.
To be more exhaustive, we would therefore need more information, in Europe at least, regarding,
Ideally, a data source would provide data about one or more of these points in a unified format for all EU countries.
