Overview
• UK smart meter deployment is starting now
• SMETS 1 published in April – Smart Metering Equipment Technical
Specifications – Defines minimum functionality for meters and
displays
• Key design considerations beyond SMETS – Total cost to install, not just asset cost – Communications performance – Future-proofing the hardware – Models for meter firmware and applications

Issues in deployment and commissioning
• Initiating a new positive relationship with customer – Trouble-free on-time high-quality process – Belief of installation team that it is a good system
• Consider total cost of (hardware + installation) – More expensive hardware could improve
installation • Less time on site • Lower risk of a failed installation and subsequent
revisit
• Installation efficiencies make material cost savings – 10% saving in install time = £157m saving for the
UK rollout • Based on April 2012 Impact Assessment costs

WAN and HAN performance
• Strongly influenced by property characteristics – Location (overall WAN coverage) – Meter location (indoor, meter box, semi-concealed)
• Distance between gas and electric meter – Construction materials (timber, brick, stone etc) – Type of dwelling (apartment, detached property etc)
• Minimise chance of failed installation – Collect information on the meter locations and
properties – Use coverage maps for WAN – Provide tools, feedback and alternate options for
installer SLIDE 5

Beyond installation – future proofing
• Challenge of rapidly evolving markets for a long lifetime asset – Maintaining functionality – Predicting total cost of ownership and ROI
• International experience – it isn’t easy! – Italy – Australia/New Zealand – Sweden
• But it is possible – E.g. In-field upgrade of FlexNet meters in USA SLIDE 6

Choosing the right smart meter
• Traditional – Hardware cost – Performance stability – Reliability – Day 1 functionality
• Standards • Protocols
• Compatibility
• Additional Smart specs – Which processor – How much memory – Which OS – WAN hardware capability – HAN hardware capability
– Metrology capability – User interface capability – Upgrade processes – Ease of configuration

Requirements trends to consider
• Core functionality – Increasing complexity of Time of Use – Credit, Prepayment and PAYG operation – Increasing resolution of load profiling – User interface with smart meter system
• Future applications – EVs – HEMS – Microgeneration – Demand response appliances

Recent history in smart meter evolution
• Code growth
• Non volatile storage – Even faster than code size
• Increasing frequency of communications – From monthly to hourly
• Increasing communications bandwidth – Larger volumes of data
• Security requirements – Increasingly heavyweight

Writing meter firmware applications
• Traditional – Meter vendor writes
firmware • Using subcontractors • Licensing in stacks etc
– No third party access • Code is proprietary • Code often monolithic • Security issues
– Slow code evolution • Limited set of resources • Limited customisation per
customer
• Smart – Meter vendor provides
core OS • Including core metrology • Including hardware drivers
– Applications for everything else
• Third parties can develop • Defined interfaces
• Independently installable
– Meter vendor certifies

Predictions
• Small choices in design will have BIG impact on installation
• Expect unknown applications – for home and grid management
• Expect third party app development (already happening in US – ‘Green Button’ initiative)
