In the recently published Summary of Responses to the EV Smart Charging consultation, the Department for Transport confirmed their intention to mandate that all new private chargepoints are smart, subject to further policy development and the continued development of device-level standards. To deliver consistent minimum standards and meet government objectives for smart charging, as outlined in chapter 2 of the consultation, the smart chargepoint regulations will ordinarily require compliance with elements of the BSI PAS standards for energy smart appliances (specifically PAS 1878).
The ESA PAS (1878) is now available for public review and can be found here, where the British Standards Institute (BSI) will be gathering technical comments. For further details, you can contact BSI directly on SmartAppliances@bsigroup.com or visit the BSI Standards Development Portal.
As part of our Smart Energy and Utilities Group, we are holding a member input session on the consultation. The deadline for submission is 2 September 2020.
This PAS covers:
• the generic, or specific, functional requirements of ESAs, which enable the performance of DSR-based activities;
• the ESA system architecture for DSR-based activities, including communication links and object functionalities and, in particular, the interfaces between the CEM and the ESA and between the CEM and the DSRSP;
• the ESA operational sequence of DSR-based activities, including communication protocols where necessary; and
• relevant ESA lifecycle considerations.
This PAS also covers compatibility with smart meter technologies, specifically full compatibility with the GB smart metering system.
This PAS applies the following criteria in defining the requirements that are to be met by an ESA performing DSR-based activities.
• Interoperability: the ability of an ESA to work seamlessly across any appropriate DSR service operated by any authorized system actor.
• Data privacy: the secure transmission and storing of data on the device or with any controlling party.
• Grid stability: the prevention of outages on the grid caused by inappropriate operation of ESAs.
• Cyber security: the appropriate protection of ESAs from unauthorized access and the correct use of ESAs by authorized parties only in order to achieve valid DSR events.
For requirements relating to compatibility with all forms of DSR-based activity, two types of DSR are covered in detail:
• supplier/utility set electricity tariffs; and
• TSO/DSO requested services with responses called by DSRSPs (transmission and distribution network level, including grid frequency sensitive).
This PAS specifies the minimum requirements to perform these DSR-based activities, in line with the four criteria above.
This PAS covers the following electrical appliances that are used in a domestic or small business settings):
• heating, ventilation and air conditioning (HVAC) appliances;
• cold appliances;
• wet appliances;
• battery storage; and
• smart EV chargepoints.
This PAS does not cover:
• the deployment and functional configuration of the wider DSR environment;
• standards implied by existing relevant overarching regulation, for example the general safety or other aspects of the non-smart functionality of an ESA; and
• contracting, payment services or general consumer protections.
