New rate proposals from the CNMC


Rates Sector 0


The CNMC proposal defends that the cost of the networks be based on the energy and power consumed, as well as propose an extension of the hourly discrimination, encouraging more efficient consumption. Its objective is that the consumer is aware of the transport tolls, the different types of consumers and how much the cost of the networks in their invoice.

Following Royal Decree 1/2019, of January 11, on urgent measures to adapt the powers of the National Commission of Markets and Competition (CNMC), according to the European guidelines, the powers of Define the methodology for calculating tolls for access to electricity networks to cover the remuneration of transport and distribution.

For this reason, the CNMC, through the Circular proposal of July 25, 2019, which establishes the methodology for the calculation of transportation and electricity distribution tolls. It has proposed a series of changes both in the tariff structure and in the calculation of tolls.

It is worth mentioning that there has been no change in the tariff structure since Order ITC / 2794/2007, of September 27, by which electricity rates are reviewed. Similarly, access tolls have not been modified since Order IET / 107/2014, of January 31, which reviews the access tolls for electrical energy for 2014.

The circular will apply to the determination of the prices of the terms of billing of transport and distribution tolls.

It is not yet a definitive structure, since it is in a period of allegations and will be approved before January 1, 2020.

However, in Lumisa we want to show you how they would be for the moment:

3.0A Rate

This is the rate with 3 periods in power and energy, with contracted power exceeding 15 kW. According to the Circular, it is renamed 3.0DT.

The substantial modification lies in the change of accrual passing to 6 periods of energy:

  • The P1 power becomes the P1 power in the new 3.0TD rate
  • The power P2 becomes the powers P2, P3, P4 and P5 in the new 3.0TD rate
  • The P3 power becomes the P6 power in the new 3.0TD rate
Rate 2.0A, 2.2DHA, 2.1A and 2.1DHA

All 2.X rates have 1 or 2 periods in energy and only one in power and are for contracted powers equal to or less than 10 kW. According to the Circular they are called 2.0TD.

The substantial modification also lies in the change of accrual:

  • It goes to 6 periods of energy (with the same accrual as the 6.1DT rate, previous 6.1A) in the new 2.0TD rate.
  • Go to 2 periods of power in the new 2.0TD rate.

6.1 6.1TD 6 6

Energy accrual

Energy accrual will be unique for all rates, depending on the season you are in, geographical area, the day of the week and the time of day.

Therefore, 4 seasons are set:

  • High
  • High average
  • Half
  • Low

And classify the seasons according to the geographical area:

Iberian Peninsula
  • High season: January, February, July and December.
  • High middle season: March and November.
  • Mid season: June, August and September.
  • Low season: April, May and October

Melilla
  • High season: January, July, August and September
  • High middle season: February and December.
  • Mid season: June, October and November.

In the same way, each season is assigned a type of day according to:

  • Type A: From Monday to Friday, no high season holidays.
  • Type B: From Monday to Friday, non-holidays of high middle season.
  • Type B1: From Monday to Friday, no mid-season holidays.
  • Type C: Monday through Friday, non-holiday season.
  • Type D: Saturdays, Sundays, holidays and January 6.

Finally, it defines the periodification of the power that will be the same as the energy, except in the 2.0TD rate that will have only two periods in power:

Monday to Friday:

  • Period Tip: 8: 0 h to 24: 0 h.
  • Valley Period; 24:00 h

Saturdays, Sundays and holidays:
