The Technical Architecture and Business Architecture Sub-Committee (TABASC) was established to provide advice and guidance to the SEC Panel regarding Technical Code Specifications, End-to-End Technical Architecture, and Business Architecture. The TABASC meets on a monthly basis.
End-to-End Technical Architecture means the DCC Systems and the Smart Metering Systems together, including as documented in the Technical Code Specifications. Business Architecture is the framework designed to enable Parties to use the Services and/or to enable Parties, Energy Consumers and those acting on behalf of Energy Consumers to access the functionality described in the Technical Specifications.
The functions of the TABASC, as set out in Section F1 of the SEC, include but are not limited to, the following:
Document Development and Maintenance
- Develop and maintain the Technical Architecture Document
- Develop and maintain the Business Architecture Document
Details on both documents are available on the Business Architecture Document and Technical Architecture Document page on the SEC Website.
Support and Advice
- Provide support and advice in respect of Modification Proposals that affect or are likely to require change to the Technical Code Specifications, the End-to-End Technical Architecture and/or the Business Architecture
- Provide support and advice in respect of Disputes relating to Technical Code Specifications, the End-to-End Technical Architecture and/or the Business Architecture
- Review and report to the Panel on the effectiveness of the End-to-End Technical Architecture and of the Business Architecture
- Review and report to the Authority and the Panel the effectiveness of the HAN Requirements
The TABASC has developed a set of principles to facilitate the assessment of Modification Proposals, which can be found on the right, under Documents.
The TABASC is made up of:
- 6 Large Suppliers
- 2 Small Suppliers
- 2 Network Parties (1 Gas and 1 Electricity)
- 2 Other Parties
- An Independent Chair
You can view the current members below, and enquire about our current vacancies here.

Technical and Business Expert Community (TBEC)
Due to the wide and varied nature of the duties that fall within the Technical Architecture and Business Architecture Sub-Committee’s (TABASC’s) remit, the Technical and Business Expert Community (TBEC) was established to support and provide expertise to the TABASC when required.
Auxiliary Load Control Switch (ALCS) and Home Area Network (HAN) Connected Auxiliary Load Control Switch (HCALCS) Label Online Forms
The latest label list for ALCS and HCALCS can be found here.
The Electrical Smart Metering Equipment (ESME) is able to control load switching for different electrical appliances through integrated ALCS and connected HCALCS.
As variable tariffs become more common, so too will the use of ALCS and HCALCS, allowing Energy Consumers to optimise their electricity consumption by setting appliances to draw electricity at beneficial periods of the day. For example, an ESME could control a water storage heater to draw electricity only in periods of lower tariffs.
As take up increases, it is beneficial for Energy Suppliers to be aware of what these devices are being used for. The ALCS and HCALCS labels list assists in recording the variety of uses and introduces a standardised naming convention for all ALCS and HCALCS labels.
In addition, the list is used to validate the ALCS and HCALCS description (Switch Description) in the DCC’s systems. Essentially, an Import Supplier can update the switch description by executing Service Request Variant (SRV) 6.14.1 – UpdateDeviceConfiguration(AuxiliaryLoadControlDescription). Within the specific data items for this service request, there are set parameters for switch description, which are the validated against the labels list.
Once these labels have been reviewed by the Technical Architecture and Business Architecture Sub-Committee (TABASC), the labels list will be published here.
Live Import Suppliers, once logged in to the SEC website, can use the online forms below to inform the TABASC if they wish to add, edit or remove ALCS / HCALCS labels:
The TABASC requests, as part of each submission, that you briefly explain why you would like any changes to be made. If you have any questions, please contact the SECAS Helpdesk.
