1. An apparatus for demand side electrical load management, the apparatus including a communication arrangement operable to receive messages from a remote site and a display arrangement operable to display information, characterised in that:

  • the communication arrangement is operable to receive from a remote site an indication message indicative of an instantaneous electricity consumption, the display arrangement being operable to display visually the instantaneous electricity consumption;

    the communication arrangement is further operable to receive from the remote site a threshold message including an indication of an electricity consumption threshold and an indication of a time period within which the consumer must limit his or her electricity consumption to comply with the electricity consumption threshold;

    the display arrangement is operable to display a time remaining within which the consumer must limit his/her electricity consumption, andthe apparatus further including an acoustic transducer operable to emit an audible beeping alert indicative of receipt of the threshold message, a frequency of the beeping alert being dependent on a difference between current electricity consumption and the consumption threshold.
