Smart meters will facilitate demand side response (DSR) through a number of load control features supported by the smart metering system.
DSR could give consumers new options to help them manage their electricity usage, allowing them to schedule usage for particular times or to vary it on demand to save money. Widespread use of load control could also allow better and more cost-effective balancing of supply and demand. It would reduce the costs associated with unexpected peaks and help to provide security of supply as well as helping with the integration of renewables. This could potentially reduce expenditure on building generation capacity and reinforcing the transmission and distribution networks.
