either locally, by timeswitching (i.e. via a timeswitch in, or attached to, the Meter); or
remotely, using a time signal from the Radio Teleswitch Service (RTS).

In the case of timeswitched Meters, Market Domain Data (MDD) pre-defines both the time-of-use registers and the switching times.

In the case of teleswitched Meters, MDD defines the registers, but the Teleswitch Agent notifies the Supplier Volume Allocation Agent (SVAA) of the broadcast switching times for each Teleswitch User (TSU) and a Teleswitch Group (TSG) on a daily basis.

Suppliers who use the RTS to switch load or registers should assign Metering Systems to an RTS Standard

Settlement Configuration (SSC). An RTS SSC includes two additional data items in MDD:

a TSU ID; and
a TSG ID.

The Time Pattern Regime (TPR) IDs for an RTS SSC have a teleswitch/clock indicator value of ‘S’ (as opposed to ‘C’ for clock-switched or timeswitched) and, by convention, have five-digit IDs that are greater than 00999.

Issues associated with the introduction of smart Meters

With the introduction of smart metering, the Data and Communications Company (DCC) will process requests from Suppliers to remotely switch registers and control load. In addition, it will send commands to be applied by the relevant smart Meter.

When a Meter Operator Agent (MOA) replaces an RTS Meter with a smart Meter, the Supplier can retain the Metering System on its existing RTS SSC. The MOA can then configure the smart Meter’s switching calendar so that the load (and/or time-of-use registers) is set to the same time as the RTS group to which the Metering System previously belonged. However, this presents three problems:

Assigning a non-RTS Metering System to an RTS SSC means that the Metering System will be mislabelled;
Suppliers, Supplier Agents and Distribution System Operators (DSOs) will lose the distinction between smart Meters and teleswitch Meters and will be unable to track the migration of RTS Metering Systems; and
When the RTS signals are eventually no longer broadcast for the RTS group in question, any Metering Systems left on the RTS SSC will no longer be settled correctly.

In February 2015, the Profiling and Settlement Review Group (PSRG) completed a project to identify ways to ensure accurate Settlement for dynamically-controlled load (and time-of-use registers) through smart Meters. The PSRG concluded that Half Hourly (HH) Settlement for dynamically-controlled load is the best longer-term option.

In the shorter term, Suppliers can treat dynamically switched smart Meters as static timeswitched (with an approximation in Settlement). Static or semi-static switching regimes already account for a significant majority of RTS Metering Systems, so Suppliers can move these Metering Systems to an equivalent timeswitched SSC.

At its 3 February 2015 meeting, the Supplier Volume Allocation Group (SVG) (SVG168/09) agreed with the PSRG’s recommendations. It requested that Elexon raise a Change Proposal (CP) (CP1443) to mandate that Suppliers move smart Meters with dynamically- controlled load to a new (or existing) non-RTS SSC upon installation of a smart Meter.

Establishing valid SSCs

The main Supplier from the old Public Energy Supply (PES) regions tends to have the majority of the teleswitch customers on each SSC within each Grid Supply Point (GSP) Group. The SVG proposed that these Suppliers voluntarily map the SSCs for the GSP Groups that map to the old PES regions. We note that this would be voluntary although it is in all Suppliers’ interests. The SVG has proposed that Elexon provides this central guidance to Suppliers on what a valid replacement SSC would be, and that Elexon collates and publishes the mappings on the BSC Website so that all Suppliers can refer to it.

THE GUIDANCE

There are a number of sources of data that can assist in identifying suitable existing SSCs to map the existing RTS SSCs to. These sources are summarised as follows:

The Electricity Networks Association (ENA) Teleswitch Quarterly Report data;
Market Domain Data (MDD);
The Teleswitch Contact Interval Data report File (D0279); and
The Daily Profile Report (D0018) data.

If a suitable SSC cannot be identified, Suppliers should consider raising a new SSC with appropriate switching times.

The Process Steps

Step 1- How do I identify the SSCs that need to be mapped?

In order to Identify the SSCs that need to be mapped you should use the Average Fraction of Yearly Consumption

(AYFC) table in MDD.

You need to filter by the GSP Group (you wish to consider) and by Time Pattern Regimes (TPRs) greater than 999. You can then remove duplicates by deselecting the effective dates and AYFCs using the remove duplicates function in Excel:

This will provide the list of SSCs to be mapped for the GSP group (of which this is an extract):

GSP Group ID	Profile Class ID	Standard S	Effective From Settlement Date (VSCPC)	Effective From Settlement Date (AFOYCS)	Time Patt	Average Fraction Of Yearly Consumption
_A	2	126	01/04/1996	01/04/2011	1193	0.532541

_A	4	331	01/04/1996	10/04/2008	1169	0.260922

Step 2- How do I replicate Load Managed Area (LMA) SSC’s and TPR’s

Suppliers should refer to the designated Load Managed Area (LMA) notice as defined in DCUSA Schedule 8. The LMA notice will contain information to support Suppliers when replacing Radio Teleswitch (RTS) metering systems in a LMA where the current Load Switching Regimes should be replicated.

There are certain RTS metering systems that have separate Load Switching Regimes for space heating and water heating, whilst other RTS metering systems may have combined Load Switching Regimes for space heating and water heating or may simply switch space heating on its own.

In order to ensure RTS metering systems that are subject to a LMA notice are replaced with replicating Load Switching Regimes, it’s important that Suppliers are aware of these differences and understand how the LMA notices provides the information to explain both the combined SSCs for Settlements, as well as the physical on-site meter configurations required to replicate existing LMA Load Switching Regimes.

The following LMA notice extracts explain how to interpret the notice when replacing RTS meter systems that are subject to an LMA notice.

Figure.1 displays the peak and off-peak configurations for general load, with existing and replicating Standard Settlement Configurations (SSC’s), replicating Time Pattern Regimes (TPR’s) and the time periods for peak and time periods for off-peak for either a one MPAN option or two MPAN.

Figure.1 – LMA notice example

Figure.2 displays the space heating and water heating configurations with existing and replicating SSC’s, the combined TPR time periods for space heating and water heating which can be used for Settlement purposes and the separate TPR time periods for space heating and water heating which can be used for physical on-site meter configurations for either a one MPAN option or two MPAN to replicate of existing Load Switching Regimes subject to a LMA notice.

Figure.2 – LMA notice example

Step 3 - How do I identify the switched load TPR?

For the following worked example we will use SSC 0126 for Profile Class 2 in GSP Group _A.

You can identify the switched load TPRs by looking at the Valid Measurement Requirement Profile Class table in MDD. The switched load indicator is set to ‘T’ for ‘True’:

_P_r_o_{file Class}_ID

_S_t_a_n_da_r_d_S_e_t_t_leme_{nt Co}_n_f_igu_r_a_ti_o_n_ID

₁₁₉₃

₀_1/04/₁₉₉₆

₁₂₆

1194

₀_1/04/₁₉₉₆

Step 4 - How will I know if switching times are in GMT or Clock Time?

All Teleswitch times are in Coordinated Universal Time (UTC). They are converted in Settlement to clock time during the British Summer Time (BST) period if the Greenwich Mean Time (GMT) Indicator in the Time Pattern Regime table in MDD is set to ‘Y’ for Yes;

Time Pattern Regime ID	Teleswitch/Clock Indicator	GMT Indicator
1193	S	Y
1194	S	Y

Step 5 - How do I identify the Teleswitch User Groups and Teleswitch Group Ids?

The Teleswitch Time Pattern Regime table in MDD provides this mapping:

Time Pattern Regime ID	Teleswitch User ID	Teleswitch Group ID	Teleswitch Switch ID
1193	5	99	A
1194	5	99	B

Step 6- How do I identify the most common switching times associated with each TPR?

There are several methods to identify switching times for Teleswitch TPRs.

Step 6A

High level indication can be obtained from the ENA Teleswitch Quarterly Report. (For example when looking at Teleswitch User Group 5 (see tab 05 at bottom of the file) and Teleswitch group id 99 you can see the operating window for the switched load and the switching length.) The additional information column can also provide useful context.

_{Group Code}	RTS Contact	_Re_gime₍₁₎	_Dur_a_tion ₍_h_o_urs)	_Operating _W_i_n_d_ow₍₂₎	_Additi_o_n_al_Information
123	A B C D	Dynamic Dynamic Dynamic Dynamic	7 7 7 7	22:00 - 08:00 22:00 - 08:00 22:00 - 08:00 22:00 - 08:00	Not separately identified in Settlements. Always switched co-incidentally with Group Code 98; shared SSC. Dynamic switching of contactors is a maximum of 7 hours during operating window.
99	A B C D	Dynamic Dynamic Dynamic Dynamic	7 7 7 7	22:00 - 08:00 22:00 - 08:00 22:00 - 08:00 22:00 - 08:00	Dynamic switching of contactors is a maximum of ₇_h_o_u_r_s_dur_i_ng_op_e_r_ating_w_i_n_d_ow.
98	A B C D	Dynamic Dynamic Dynamic Dynamic	7 7 7 7	22:00 - 08:00 22:00 - 08:00 22:00 - 08:00 22:00 - 08:00	Dynamic switching of contactors is a maximum of 7 hours during operating window. Always switched co-incidentally with Group Codes 2, 3, 4 and 123.

Not separately identified in Settlements. Always switched co-incidentally with Group Code 98; shared SSC. Dynamic switching of contactors is a maximum of 7 hours during operating window.

Dynamic

22:00 - 08:00

Dynamic switching of contactors is a maximum of ₇_h_o_u_r_s_dur_i_ng_op_e_r_ating_w_i_n_d_ow.

Dynamic

22:00 - 08:00

Dynamic switching of contactors is a maximum of 7 hours during operating window. Always switched co-incidentally with Group Codes 2, 3, 4 and 123.

So, after following steps 1-5A above for SSC 0126 in GSP group _A, we know we are looking for an SSC that switches for seven hours between 22:00 - 08:00 GMT.

Step 6B

For many SSCs a suitable non-teleswitch SSC may be easily identified if common regimes are known that match the required pattern.

For more detail you could look at D0018 Daily Profile Data Report. Stripping out the True (T) and False (F) values shows the switching pattern for each TPR. You need to note the time of year for the file you are looking at and should also look at weekday / weekend differences:

GSP

07:00

07:30

08:00

08:30

126

1193

126

1194

Note the times in the header column above are the half-hour ending at that time. So, from following steps 1-5B above, we know that SSC 0126 in GSP group _A is a 01:00 to 08:00 GMT regime

Step 6C

You can also look in the D0279 Teleswitch Contact Interval Data Report file to see the switching times associated with the TSU and TSG Searching the file TSU 5 and TSG 99:

_TSG|99

_TSC|A|F

_TCI|010000|T

_TCI|080000|F

_TSC|B|F

_TCI|010000|T

_TCI|080000|F

_TSC|C|F

_TCI|01₀_000|T

_TCI|08₀_000|F

_TSC|D|F

_TCI|01₀_000|T

_TCI|08₀_000|F

From following steps 1-5C above, we can see that the times in the file show that all contacts for TSU 5 and TSG 99 switch from 01:00 to 08:00.

Step 7 - How do I identify a non-Teleswitch equivalent SSC?

There are several methods that should be used.

Step 7A

Using the D0018 Daily Profile Data Report data you could filter the ‘Ts’ and ‘Fs’ for TPRs (VMR (for Valid Measurement Requirement in the D0018 file) to find a matching pattern¹:

GSP

SSC

TPR

00:30

01:00

01:30

02:00

02:30

03:00

03:30

04:30

05:00

05:30

06:00

06:30

07:00

07:30

08:00

08:30

152

211

153

212

As can be seen above that both SSC 0152 and SSC 0153 provide a matching pattern to SSC 0126 and are valid for the same Profile Class and GSP Group.

Step 7B

Having identified potentially valid SSCs, it is worth looking in the Clock interval table in MDD to confirm the switching times:

Time Pattern Regime ID	Day of the Week ID	Start Day	Start Month	End Day	End Month	Start Time	End Time
211	1	1	1	31	12	00:45	07:45
211	2	1	1	31	12	00:45	07:45
211	3	1	1	31	12	00:45	07:45
211	4	1	1	31	12	00:45	07:45
211	5	1	1	31	12	00:45	07:45
211	6	1	1	31	12	00:45	07:45
211	7	1	1	31	12	00:45	07:45
212	1	1	1	31	12	01:00	08:00
212	2	1	1	31	12	01:00	08:00
212	3	1	1	31	12	01:00	08:00
212	4	1	1	31	12	01:00	08:00
212	5	1	1	31	12	01:00	08:00
212	6	1	1	31	12	01:00	08:00
212	7	1	1	31	12	01:00	08:00

From the above it is clear that TPR 00211 switches at 00:45 until 07:45 which is then rounded from 01:00 to 08:00 in the D0018. TPR 00212 is an exact match, So the correct SSC for mapping purposes would be SSC 0153.

Step 7C

It is important to check that the data is the same time in both summer and winter by looking in the Time Pattern Regime table in MDD. If it does not match it could still be a valid mapping if the switching times fall within the operation window identified in the ENA Teleswitch Quarterly Report. You can look to see if there are other options or raise a new non-RTS SSC.

Time Pattern Regime ID	Teleswitch/Clock Indicator	GMT Indicator
46	C	Y
212	C	Y
1193	S	Y
1194	S	Y

Step 8 - How do I check the Line Loss Factors are valid?

Finally, it is worth checking that both SSCs can be used with the same Line Loss Factor Class ids. To do this look in the Valid MTC_LLF_SSC_PC Combination table in MDD. This shows that both SSC 0126 and SSC 0153 can be used with LLFC ID of 7 and 43. If the LLFCs are not valid for the SSC then you will need to contact the LDSO and get a new SSC LLFC combination set up:

Meter Timeswitch Class ID	Market Participant ID	Standard Settlement Configuration ID	Line Loss Factor Class ID	Profile Class ID
126	EELC	153	7	2
126	EELC	153	43	2
176	EELC	126	7	2
176	EELC	126	43	2

General Considerations

If the switched load period for an SSC falls within the operating window for the Teleswitched SSC (TSU and TSG) then it should be a valid mapping provided the timeswitch SSC is of the same duration.

Dynamically Teleswitched SSCs

Dynamically Teleswitched SSCs by definition will not have a matching time-switched SSC. If the dynamic switching needs to be retained the only option currently is to settle such customers on a Half-Hourly basis since profiling processes for Settlement cannot model the switching pattern without some form of feedback. If a non-dynamic non- Half Hourly (NHH) equivalent needs to be mapped then the closest time-switched SSC as possible should be identified or a new SSC should be raised for the appropriate combination. The ENA Teleswitch Quarterly Report provides guidance on whether SSCs are Dynamic, Static or Semi-Static. However, many potentially dynamic SSC are in fact set to static times. Appendix A contains a table giving our interpretation from previous work in this area.

For example a Dynamic SSC would map to an existing SSC provided all switching times for the existing SSC fall within the Operating window of the Dynamic SSC and is of the same switching length:

CONTENTS

Radio Teleswitch - Standard Settlement Configuration Mapping

BACKGROUND

Issues associated with the introduction of smart Meters

Establishing valid SSCs

THE GUIDANCE

The Process Steps

Step 1- How do I identify the SSCs that need to be mapped?

Step 2- How do I replicate Load Managed Area (LMA) SSC’s and TPR’s

Step 3 - How do I identify the switched load TPR?

Step 4 - How will I know if switching times are in GMT or Clock Time?

Step 5 - How do I identify the Teleswitch User Groups and Teleswitch Group Ids?

Step 6- How do I identify the most common switching times associated with each TPR?

Step 7 - How do I identify a non-Teleswitch equivalent SSC?

Step 8 - How do I check the Line Loss Factors are valid?

General Considerations

Dynamically Teleswitched SSCs
