Meanwhile, my local formula, if I understood this correctly:
template:
- sensor:
# see https://github.com/virtualdj/pun_sensor/pull/11
- unique_id: current_retail_electricity_price
name: 'Current retail electricity price'
icon: mdi:currency-eur
unit_of_measurement: '€/kWh'
# 1.102 = 10.2% spread
# 1.038 = 3.8% MT (not sure what this is)
# 0.073 = delivery fees
# 0.042 = distribution/measurement fees
state: >
{{ (1.102 * 1.038 * (states('sensor.pun_prezzo_fascia_corrente')|float(0) + 0.073 + 0.042))|round(3) }}
Probably mixed up the formula a bit, so please do feel free to correct me, so I both get it right for myself and for others here :D
EDIT: in fact, I think it's like this
template:
- sensor:
# see https://github.com/virtualdj/pun_sensor/pull/11
- unique_id: current_retail_electricity_price
name: 'Current retail electricity price'
icon: mdi:currency-eur
unit_of_measurement: '€/kWh'
# 1.102 = 10.2% spread
# 1.038 = 3.8% MT (not sure what this is)
# 0.073 = delivery fees
# 0.042 = distribution/measurement fees
state: >
- {{ (1.102 * 1.038 * (states('sensor.pun_prezzo_fascia_corrente')|float(0) + 0.073 + 0.042))|round(3) }}
+ {{ (states('sensor.pun_prezzo_fascia_corrente')|float(0) * 1.102 * 1.038 + 0.073 + 0.042)|round(3) }}
To be honest, I don't remember at the moment where I found that formula... and I'm not sure it's actually perfect. For example grid losses and dispatchment costs are based on the kWh (so they must be multiplied) but there are also monthly costs that are not included here.
Anyway, everything it's just an indication because you won't get the correct result until near the end of the month.

As explained by @ virtualdj, retail prices depend on the current contract with the electricity retailer, and therefore need to be computed with a template sensor.
This patch provides an example, although it is unclear where this would be positioned in
configuration.yml
