3 Drivers
• Climate change
• Smart technology
• Finance

Decarbonisation of energy supply
• Switch of load from fossil fuel to electricity and renewables– Electric vehicles– Heat pumps– Wind– Nuclear / CSC– PV– CHP

Smart devices and communications
• Increasingly every device has intelligence– Smart meters– Smart appliances– IPv6 and the Internet of everything
• Communications media becoming available for all applications– R.F. / PLC / twisted pair / fibre– Broadband

Finance
• Need to rebuild generation capacity
• Need to rebuild TS/DS
• Can’t afford business as usual
• The role of the smart grid is to:– Avoid generation capacity– Avoid reinforcement of TS and DS– Increase the utilisation of the Grid
• Make use of the smart technology

Features of Smart Grid
• New advanced technology for LV Grid
• Improved operation of LV Grid
• Demand management– Control of load – Control of generation
• Data and communications

Issues for the UK• Security – the more powerful you make the grid the more this
is an issue
• Does the UK energy market model make us an outlier or a leader?
• Smart metering – can it be designed to support smart grids without halting the roll out?
• Development of new players and businesses – energy services/aggregators
• Demand response:
– How much flexibility in load/generation
– Market based or remote control, manual or automatic
