  • Synopsis

    Electricity networks in Great Britain were not designed to accommodate the significant additional demand that certain consumer devices (such as electric vehicle (EV) chargers) presents. In some circumstances, Electricity Network Operators will be required to act to find a balance between their obligation to operate cost-effective, safe and reliable electricity networks and the need to support customers who wish to adopt low carbon technologies such as EVs.

    Whilst the Electricity Network Operators are aiming to use market-sourced flexibility services to keep the networks within their limits, there is a need for a system to prevent supply interruptions and/or damage to networks in limited circumstances as a short-term, last resort action in emergency scenarios – i.e. the absence or failure of market-based solutions and where failure to act is likely to cause power outages due to overloads.

    The SEC Modification proposal SECMP0046 is progressing the technical aspects of implementing such a system using the Smart Meter infrastructure, yet as this involves turning down demand it will require a change to DCUSA.

    It is felt that Schedule 8 would a logical place to accommodate such amendments and detail the governance arrangements for the process.
