DTN and adaptors can lower cost and risk for players connecting to half hourly settlement architecture – ElectraLink

May 18, 2021

The Half-Hourly Settlement (HHS) Architecture Working Group (AWG) recently published their preference for an event-driven architecture (EDA) to deliver the HHS programme, enabling real-time data transfer. As energy market transformation continues, real-time data transfer will be more broadly required, and we at ElectraLink are very supportive of this important step towards the future of the energy system.

However, the introduction of an EDA will require a significant overhaul in how industry manages and interacts with data. It will present challenges in its implementation, including the need to make sometimes significant system changes at a local level. So, while ElectraLink supports the use of an EDA, it needs to be delivered in a cost-effective, low risk way and market participants should be given time to ready their systems for when an EDA is required.

ElectraLink suggests the trusted, established Data Transfer Network (DTN) – the foundation of the Energy Market Data Hub (EMDH) – be used in conjunction with adaptors to give players autonomy and cost savings when connecting to the EDA. When the process an EDA is supporting is not in real time, the use of existing infrastructure is a low risk, cost-effective alternative for market participants to manage their own approach to connecting with the new HHS system.

This hybrid approach incorporating the DTN, adaptors and EDA allows a secure, comprehensive move towards a full EDA model for settlement processes. This position is recommended in the AWG consultation and ElectraLink has outlined how this could work in our White Paper.
