# Supplying distribution grid exit points in Belgium

## Transmit natural gas to a distribution grid exit point without making an explicit capacity subscription

## Beschreibung

### Want to transmit natural gas to a distribution grid exit point?

If so, you don't have to subscribe to capacity yourself. Every month, we make implicit peak-capacity allocations to you based on your end users' market share within each aggregated receiving station (ARS).

We do this based on four end-user profile segments:

**Telemetered end users **

- End users whose consumption is measured remotely on an hourly basis (S30)

**Profiled end users**

- Non-household consumption of < 150,000 kWh per year (S31)
- Non-household consumption of ≥ 150,000 kWh per year (S32)
- Household consumption (S41)

**In May each year (N), **we determine an hourly exit capacity value for the whole of Belgium, in kWh per hour and at an equivalent temperature of **-11°C (Q _{-11C}). **We work this out based on an analysis of the five most recent winters.

We spread this hourly capacity value at **-11°C** across the four segments which also apply to Belgium as a whole and to a period from 1 October N to 30 September N+1:

- Q
_{-11C}S30 - Q
_{-11C}S31 - Q
_{-11C}S32 - Q
_{-11C}S41

### How do we determine your allocated capacity?

For segments S31, S32 and S41, we work out your individually allocated capacity based on the level of the calculated commodity allocated by the **distribution system operator** (DSO).

For segment S30, we do this based on the respective individual end user's peak consumption over the **previous 12 months**.

### More details about calculations by segment

**S31 & S41**

- Each month, the DSO sends us a commodity allocation per shipper of a given ARS within segments S31 and S41.

- Based on Q
_{-11C}S31 and Q_{-11C}S41, we perform a monthly calculation for the period from 1 October N to 30 September N+1.

- We determine the capacity allocation per ARS by dividing your commodity allocation per ARS for S31 and S41 by the commodity allocation for the whole of Belgium and multiplying by Q
_{-11C}S31 and Q_{-11C}S41.

**S32**

- The DSO sends us the commodity allocation of a given ARS for segment S32 for January and February.

- Based on Q
_{-11C}S32, we perform a monthly calculation for the period from 1 October N to 30 September N+1.

- We determine the capacity allocation per ARS by dividing your commodity allocation per ARS for the months of January and February by the total for Belgium for these 2 months and multiplying by Q
_{-11C}S32.

**S30**

- The DSO sends us the hourly values per shipper for the individual telemetering readings of a given ARS for segment S30 spread over 12 months.

- We determine the capacity allocation per ARS by dividing the sum of peaks over a 12-month period of your telemetering readings by the total of all hourly peaks of all telemetering readings for the whole of Belgium and multiplying by Q
_{-11C}S30.

By way of illustration, here is an example with two ARSs and two shippers for segment S31 :

Q_{-11C}-capacity for segment S31/Belgium = 1,000 kWh/h

### Do you already estimate your distribution capacity ?

- For the segments S31 et S41:
- Take the standard annual consumption of your client (kWh).
- Divide this consumption by the indicative estimation factor which corresponds to the number of operating hours.

- For the segment S32:
- Take the consumption of the months of January and February of your client (kWh).
- Divide this consumption by the indicative estimation factor which corresponds to the number of operating hours.

- For the segment S30:
- Take the peak consumption of your client (kWh).
- Multiply this consumption with the indicative estimation factor.

### Below you will find an overview of the indicative estimation factors that apply from 1 October 2019 to 31 September 2020

**Telemeasured end customers**

The yearly indicative estimation factor for end customers type S30 (IEFy, S30) = **0.883**

**Profiled end customers**

The yearly indicative estimation factor for end customers type S31 (IEFy, S31) = **1583**

The yearly indicative estimation factor for end customers type S41 (IEFy, S41) = **1593**

The yearly indicative estimation factor for end customers type S32 (IEFy, S32) = **566**
