IoT Technologies for Smart Grids
• Pros: – IoT grids allow energy distribution to be managed in real
time based on immediate data rather than historic patterns of energy use (Predictive Maintenance)
– IoT grids and smart meters open the door to energy services and payment tariffs that could dramatically reduce business energy costs
– Remote/scheduled control electric appliances utilize the value of automation.
– Consumption data provide great insight
• Cons:– Market re-structure make technological change difficult
– smart grids/devices could lead to more security breaches in the future

Smart Meter Data Traffic Scenario

Smart Meter Penetration
Smart Meter Installed Units
Total Data Traffic % of TW Mobile
*20% 2,400,000 1.44Mbps *7.9%
40% 4,800,000 2.88Mbps 15.8%
60% 7,200,000 4.32Mbps 23.7%
80% 9,600,000 5.76Mbps 31.6%
100% 12,000,000 7.2Mbps 39.5%
Large scale of smart meter network delivers tiny data traffic. Can the upfront cost of an IoT network be justified by the value of data delivery?
DECC puts the cost per household of installing smart meters at £214.50. British Gas saving per household stands at just £26 per year.(Telegraph, Nov 5 2015)
The architecture of smart meter infrastructure remains ambiguous. Such as quality of service; demarcation point; ownership of recurring cost.., etc.
Smart meter data traffic has no impact on mobile operator’s network, but the installed base will consume a considerable amount of resources of SGW.
No incentive to the monopolistic electricity supplier.
