1.1 In scope
This PAS sets out a common definition of demand side response (DSR) services for actors operating within the consumer energy supply chain and provides recommendations to support the operation of energy smart appliances (ESAs). The consumer-focused approach outlined in this PAS can coexist with other forms of balancing or
DSR.
NOTE 1 Regulated market participants currently use a range of balancing services. This PAS is not intended to limit or replace the operation of other forms of balancing or demand management, which fall outside the scope of this PAS and PAS 1878:2021; for example, DSR regarding larger industrial and commercial electricity users.
This PAS is aimed at those organizations responsible for providing and delivering
energy services to domestic (e.g. individual households) or small business (i.e. SME) premises, which are collectively referred to as consumers. The cyber security principles in this PAS apply to organizations performing any form of DSR, or sending remote signals to appliances to shift or modulate their energy consumption or supply.
With regards to compatibility with all forms of DSR-based activity, the two types of consumerDSR covered by this PAS are those employing ESAs, compliant with the specification in PAS 1878:2021, that implement:
-
a) routine DSR implemented through supplier set electricity tariffs or other electricity-related incentives; and/or
-
b) response DSR initiated at the request, often made in near real time, of regulated electricity market participants.
This PAS provides only the minimum recommendations to perform DSR-based activities involving electrical appliances used in domestic or small business settings. The specific appliance categories in scope for domestic DSR service are:
-
1) heating, ventilation and air conditioning appliances (HVAC);
-
2) cold appliances;
-
3) wet appliances;
-
4) battery storage; and
-
5) smart EV chargepoints.
NOTE 2 Any other type of appliance which meets specifications set out in PAS 1878:2021 can be considered an ESA.
