Smart Cities: Commercial Viability
Integration and commercialisationFew unfulfilled technical challenges Many individual technologies trialled and proven Current solutions are low-volume, high cost
Isolated solutions, little integration Many duplicated functions and systems
For commercial successMust be more cost-effective than “Dumb City” in the long termMaximum benefit leveraged from every system and piece of dataInterchange of relevant data must be possible Security and privacy must be designed in

Communications examplesUnified single system e.g. UK Smart Metering
AdvantagesOnly one system to install Lower infrastructure cost ?
Clear development path
DisadvantagesLong time to market Already obsolete ?
Complex specificationInflexible, inappropriate
Multiple competing systemse.g. US Smart Metering
AdvantagesCompetition lowers costOngoing evolutionFeatures driven by business value
DisadvantagesCommercial access to network For other users
Higher running costsMarket complexity

Unifying systems for the Smart Grid
Old thinkingStandardised communicationsPrescriptive functionalityLittle flexibility
New thinkingOpen systems Published API’s,
Interface at system (not device) level Connectors & plug-ins
Flexible and adaptable

Example: combining data, synthetic sensors
E.g. smart street lightMotion sensorLight sensorCommunicationsTemperature
Primary functionEnergy saving Dimming Turns off when no traffic Turns on ahead of traffic
Count traffic flowFeed into traffic control systemsUseful during day
Calculate speedsTimes as vehicles pass
Measure sunlightPV generating capacityWeather forecasting

Unifying the System – is it possible ?
Highly complex systemsMultiple dimensions even for relatively simple functionalityEvolving technical and business interactions
EitherDevelop comprehensive suite of standards (CEN/CENELEC/ETSI)Encourage manufacturers to build products that meet themInnovators must influence standards to facilitate new functionality
OrDevelop open systems and API’sAllow innovation and competition to generate the solutionsWrite standards based on the solutions that work
