MP247 'Future Dating of Service Requests for SMETS1 Devices'

Smart Energy Code (SEC) Appendix AD ‘DCC User Interface Specification’ (DUIS) confirms that all Future Dated Requests for Smart Metering Equipment Technical Specifications (SMETS) 1 Devices are held by the DCC and released accordingly to meet their specified date. This means that even if a User sends a Service Request (SR) in advance of the execution date, these requests are held at the Data Service Provider (DSP) and released once the execution date and time of the request is due. Whilst there is existing functionality within DCC systems to control the rate at which these requests are released, Supplier behaviour seen by the DCC is to send the requests as on-demand requests.

The Proposed Solution is to allow DCC Users to send Future Dated Service Requests to SMETS1 Devices without being held at the DSP, for SRV 1.1.1 ‘Update Import Tariff (Primary Element)’, SRV 1.2.1 ‘Update Price (Primary Element)’, SRV 1.6 ‘Update Payment Mode’, SRV 2.1 ‘Update Prepay Configuration’, SRV 6.4.1 ‘Update Device Configuration (Load Limiting General Settings)’ and SRV 11.3 ‘Activate Firmware’.

The Alternative Solution is to allow DCC Users to send Future Dated Service Requests to SMETS1 Devices without being held at the DSP, for only SRV 1.1.1 ‘Update Import Tariff (Primary Element)’ and SRV 1.2.1 ‘Update Price (Primary Element)’.
