What is PAS 1878 - Energy smart appliances about?
BSI is working with the UK Government to encourage the uptake of safe, secure, and interoperable Energy Smart Appliances (ESAs). These are needed for the active management of demand on the electricity network, known as Demand Side Response (DSR).
PAS 1878 on energy smart appliances is a critical component in this because it details the requirements and criteria necessary to make an energy-smart appliance compatible with DSR activities.
Who is PAS 1878 - Energy smart appliances for?
PAS 1878 on energy smart appliances can be adopted by:
- Manufacturers and maintainers of energy smart appliances (ESAs)
- Manufacturers and maintainers of consumer energy managers (CEMs)
- Demand Side Response energy providers/energy aggregators
- Distributed power network operators
What does PAS 1878 - Energy smart appliances cover?
PAS 1878 specifies requirements and criteria that an electrical appliance needs to meet in order to perform and be classified as an energy smart appliance (ESA). It defines the attributes, functionalities, and performance criteria for an ESA, and specifies how compliance with these can be verified.
PAS 1878 covers:
- The generic and specific functional requirements of ESAs that 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 Customer Energy Manager (CEM) and the ESA and between the CEM and the DSR service provider (DSRSP)
- The ESA operational sequence of DSR-based activities, including communication protocols where necessary
Why should you use PAS 1878 - Energy smart appliances?
Some of the key benefits of PAS 1878 on energy smart appliances include:
- It provides a specification to manufacturers of ESAs that can be used to certify their products as ESAs, in accordance with certification schemes
- It defines the ecosystem within which an ESA can operate
- It specifies the parameters within which ESAs shall communicate signals to DSR service providers, giving those service providers the information needed to develop the infrastructure to receive and respond to those signals
PAS 1878 thereby enables the standardized control of energy smart appliances on an electricity network in order to:
- Match the short-term availability of intermittent generation sources such as wind and solar renewable energy Decrease the peak load on transmission and distribution networks, alleviating the need for network upgrades to handle new domestic appliance types such as electric vehicle (EV) charge points and electric heating, ventilation and air-conditioning systems
- Allow control of electricity network characteristics such as grid frequency, system inertia, and network voltage, and provide immunity from network and generation outages
- Allow the offset of short-term market imbalances by controlling flexible load on the network
