17Dutch approach to standards
- Standards are needed for interoperability
- All vendors claim interoperability, yet using
different protocols and / or implementations - Choice for open standards is evident
- Choosing a (open) protocol is not enough to
facilitate reaching interoperability a companion
standard is required - Choosing a vendor specific companion standard may
lead to vendor lock-out or biased tenders - Utilities and meter vendors have to work together
to attain an interoperable solution - Meter vendors for technical knowledge and to
prevent vendor lock-out - Utilities for functional requirements and making
final decisions - Only labelling as a standard is not enough

27Costs and benefits
- Investment costs
- meters ( write-off)
- concentrators
- data transmission lines
- data processing systems
- installation, meter site renewal
- project management
- customer info / education
- Operation costs
- data processing
- customer service
- maintenance / renewals
- Benefits
- maintenance costs of existing meters falls away
(e.g. repairs) - better accuracy
- lower reading costs (meters of all energy kinds
covered) - lower billing / contract costs
- technical / non-technical losses
- efficient network operation, forecasting
- deferred capacity investments
- more efficient operation of generating capacities
Which are the valid ones in my project?
28Barriers (from EU aspect)
- Investment costs and risks do not coincide with
benefits - it is necessary to regulate the distribution of
the benefits - Data protection and data security concerns
- Long return of investment
- in countries with low income / consumption /
population density justification of the business
case is more difficult - Social effects
- effect on labour
- low income customers need protection against high
spot prices
But
If smart metering is implemented differently in
the various countries or if its only sporadic,
the most important advantage, the single EU
energy / services market cannot be realized
29Considerations 1
- National/regional characteristics current
situation and trends - level of market liberalization achieved,
responsibility for metering - level of consumption, prices, incomes
- controllable loads
- balance between generation capacity and demand
- consumer density, network properties
- proportion of energy-savvy customers
- Multi-energy coverage
- Specification of minimum and optional functions
(e.g. Local display) - Data protection and security
- Roll-out strategy
- mandatory or not
- organization network company, retailer, third
party - road map
- Lifetime of technologies and equipment compared
to project duration - Allocation of costs and benefits
- Customer protection
30Considerations 2
- Project scope
- regional analysis, national consolidation (see
Australia) - Economic environment, current and forecasted
- Starting internal reference conditions
- e.g. meter park, current costs
- Methodology for costbenefit analysis,
sensitivity calculation - Project duration (e.g. 20 years)
- Calculation of Net Present Value (NPV)
- Allocation of costsbenefits, transferring
benefits to end customers - And many more....
31Some lessons learned
- Role of the State and the Regulator
- e.g. mandatory rollout with appropriate
conditions - Full coverage (at least by region)
- National circumstances must be observed
- To justify business case, maximalize benefits,
minimalize costs - all possible benefits must be exploited
- Minimum requirements shall be specified
- Interoperability based on open, international,
proven standards. e.g. IEC 62056 DLMS/COSEM - Coverage of future requirements (e.g. smart
grids) - Supply consortia
32Summary 1
- Smart metering is driven by political and
business drivers, technologically possible - what, when, under what conditions, to meet what
requirements - Benefits
- energy efficiency energy-conscious customers
- well working liberalized market all customers
- energy saving society
- business efficiency, new services supplier
- network efficiency grid operator
- need to transfer to the end customer?
- Risks return of investment, data security,
social consequences - co-operation of end customer is indispensable
- Standardisation and flexibility to accommodate
future needs
33Summary 2
- Role of metering equipment becomes even more
important - Deep influence on business processes
- Suppliers and purchasers must co-operate
- New players telecommunication and data
processing companies - The correct solution depends on local conditions
