Motivations for Smart Metering

Political

Energy efficiency / CO2 reduction

Pricing transparency / consumer protection

Energy suppliers

Improvement of the billing process

New possibilities for customer service

and sales products. . . to bidirectional communication

Smart Metering Regulatory Framework in the EU/Germany

Customer is entitled to demand

smart meters for metering

electricity, gas, district heat, water

and hot water consumption

EU Directive2006/32/EU Art. 13

From 1 January 2010, obligation touse smart meters in new or

extensively renovated buildingsGerman Energy Industry Act

Sec. 21b (3a). . . or in existing metering

systems if requestedby the customerSec. 21b (3b)

Right of customer:

energy suppliers areobligated to make out

intra-year invoices

if requested by the customer

German Energy Ind. Act Sec. 40 (2)

Obligation of

energy suppliers:

tariffs depending on load/

time of day to be introduced

for electricity end users by

30 December 2010.

German Energy Ind. Act Sec. 40 (3)

Condition: if technically feasible and economically reasonable

EU Directive Transposed into National Law (II)

Sec. 40 of German Energy Industry Act:

From 1 January 2010, suppliers are obligated to bill energy costs for periodsnot substantially exceeding twelve months. If the customer wishes, thesupplier is obligated to invoice the customer on a monthly, quarterly or half-yearly basis.

Remote meter reading is an economically viable option for billing periods

shorter than one year.

Remote billing

Smart meter

Solution: smart meters with

remote meter reading

EDL 40 meter

EDL 40 meter costs are not accepted as operating expenses in the regulated market.

Smart Residential Gas Meters

Type of meter Manufacturer Features

Diaphragm meter - Elster Kromschrder

- Itron

- Flonidan

- and others . . .

Mechanical measurement principle

Reliable, low price

Current trend towards replacing mechanical by

electronic counters

Remote meter reading option

Thermal meter - Diehl Gas Meter Thermal mass flow measurement

MID-approved

Measurement principle dependent on gas

properties; only for H-gas

Acceptance currently limited

Ultrasonic meter - Landis and Gyr Measurement of ultrasonic wave transit times

Costs still a disadvantage

May be competitive in smart metering

applications

Meters being launched

Experience from E.ON 10,000 Meter Pilot Project

Customer acceptance

Over 90 % of the voluntary - participants in the pilot project are

interested in the further use of the smart meter system

Transparency of consumption and costs is the main focus and has higher

priority than potential energy savings

Regarding consumers as a whole, only a minority is interested in smart

meter services, especially when additional costs are to be expected

Privacy protection issue In Germany, energy consumption data are subject to privacy regulations;

thus encryption methods are necessary for data transfer and data

processing

EDL21 meter displays open to third parties must be protected, e.g. by PIN

code

Smart Metering: Conclusions

Standardisation is necessary and on the way according to EU mandate

Country-specific conditions and regulations for the implementation of

smart metering will remain in Europe, influencing the cost / benefit

relation

Customers, energy suppliers, and grid operators are main stakeholders in

smart metering technology, each of them pursuing their own interests

Potential benefits of smart metering gas are lower than benefits of smart

metering electricity

Smart metering communication is the nucleus for future smart grid

communication
