Invoices include the following concepts:

1. A monthly charge

2. A variable charge based in the energy consumption monthly

3. If applicable, a phi-cosine surcharge

included within this tariff scheme are divided into:

• Tariff 1-R: Low consumption for residential use (*).

• Tariff 1-R TS: Low consumption for residential use with social tariff (*).

• Tariff 1-R EBP: Low consumption for residential use of public nonprofit organizations (*).

• Tariff 1-R ELD: Low consumption for residential use, electricity dependent users.

• Tariff 1-R MA: Low consumption for residential use with self-administered meter.

• Tariff 1-G: Low consumption for all-purpose use.

• Tariff 1-AP: Low consumption for public lighting

Note:

(*) These have a reduction in the variable charge price according to verified consumption saving compared to the same period in 2015. The new supplies entered after said date compare its consumption against its first active year.

It is applied to with a maximum demand equal or greater than 10 kW but less than 50 kW

Invoices include the following concepts:

1. A monthly fixed charge per issued invoice.

2. A fixed charge per each “scope of supply” of KW capacity agreed

3. a fixed charge based on a maximum KW capacity registered, in low, medium or high voltage, applicable to the maximum capacity registered during the billing period.

4. A variable charge for the electricity consumed, without hour discrimination.

5. If applicable, a phi-cosine surcharge

If the event the customer acquired a KW capacity superior to the agreed capacity indicated and notwithstanding the appropriate to avoid a new excess, in the billing period when the transgression took place, the distributor shall bill the KW capacity effectively registered plus  50% surcharge of the supply capacity in excess compared to the agreed capacity

It is applied to customers whose maximum demand is equal or greater than 50 kW

This tariff is divided into two categories:

• Large demands with agreed with agreed maximum power equal or greater than 50 kW and inferior to 300 kW.

• Large demands with agreed with agreed maximum power equal or greater than 300 kW.

Likewise, supplies are differentiated according to three voltage types.

• Low Voltage (LV): voltage up to 1 kV inclusive.

• Medium Voltage (MV): voltage greater than 1 kV and inferior to 66 kV.

• High Voltage (HV): voltage equal or reater than 66 kV.

Invoices include the following concepts:

1. a fixed charge per invoice issued.

2. a fixed charge per each “scope of supply” of KW capacity agreed for low, medium or high voltage, with or without electricity consumption.  

3. a fixed charge based on a maximum KW capacity registered, in low, medium or high voltage, applicable to the maximum capacity registered during the billing period.

4. a charge resulting from the electricity supplied in the voltage corresponding to the provision, in accordance with the consumption registered in each of the tariff timetables: “peak”, “night-time” and “remaining hours”

5. if the supply is carried out in continuous current, a surcharge equivalent to a percentage of the price of the rectified electricity

6. It applicable, a cos phi surcharge

If the event the customer acquired a KW capacity superior to the agreed capacity indicated in b) above and notwithstanding the appropriate to avoid a new excess, in the billing period when the transgression took place, the distributor shall bill the KW capacity effectively registered, plus a 50% surcharge of the supply capacity in excess compared to the agreed capacity. If said excess is over 50% of the contracted capacity, the surcharge will be 100% over the registered surplus.  

Likewise, in Annex XIV (Sub annex I) of the Concession Contract, the Electricity Reserve Service and the Toll Service tariff, which has a similar structure to Tariff 3.
