| Latest update | Discussions with DCUSA are going on parallel with SEMP0046 to identify the cross code impacts and governance surrounding the usage of the technical solution proposed in SECMP0046. Additionally, discussions with BEIS and Ofgem are also planned regarding the SECMP0046, and what they would expect. |
What is the issue?
This modification proposes changes to the SEC to enable electricity Distribution Network Operators to use Smart Meter infrastructure to modify Electric Vehicle charging load within a household. This is in order to avoid the risk of overloading low voltage circuits from secondary substations to properties, and therefore avoid power outages.
What is the solution?
The solution discussed at the Working Groups is to use Han Connected Auxiliary Load Control Switches (HCALCS). The HCALCS will be connected to domestic Electric Vehicle chargers, and this modification seeks to allow Electricity Distributors to send the relevant Service Request via the DCC to alter the load on a domestic Electric Vehicle charger. This would be in the event that the Electricity Distributor detects a potential risk of overloading on a low voltage network.
