Vattenfall implemented a smart meter project in Sweden from 2002-2008 that replaced over 850,000 electrical meters. The project used different communication methods including power line communication, radio, and GPRS networks. The system was designed to collect meter data daily with a typical performance of over 99.5% collection. Security of the system was improved over time, allowing for remote switching capabilities. While smart metering provides data for customers' homes, smart street lighting provides opportunities for managing street lights but may require new business models and legislation to encourage broad implementation.

 And we have now in Sweden billing based on actual consumption.
 The AMR system included much more functions and technology that original
planned such as power outage reporting, power quality reporting and alarms,
power/peak control and remote switching.
 The actual total cost within investment decisions.
 The AMR Project main roll-out started up in 2002 and was completed 27:th of
June 2008. More than 99 % of 850 000 meters exchanged in December 2008
when the project was completed and closed down. Remaining meters was
changed out during 2009.

6. Communication partner - Maingate

The collection of metering data required a suitable and
reliable partner for telecom-services.
By that reason Vattenfall signed a contract with
Maingate in 2002 to support with telecom services for
the planned installation of electrical meters.
For the initial Smart Meter Project the communication volume are:
Part 1: AMR1=112 000 meters Radio/GSM 3 900 SIM 327 kmin/month
Part 2: AMR2=118 000 meters PLC/GPRS 17 600 SIM 15 GB/month
Part 3: AMR3=620 000 meters PLC/GPRS 25 900 SIM 22-32 GB/month
Additional projects for larger customers are ongoing to exchange old meter technology and
to improve communication solution. For the main part of those customer point to point
communication are used – but also in combination with existing power line communication.
Vattenfall is currently evaluating future communication solutions together with Maingate and
especially their eUICC based offering. Freedom to change operator and negotiations on
equal terms is something Vattenfall highly appreciate.

7. Experience of communication on PLC, radio and GPRS
The performance of the communication
solution is on a high level. Meter values
and other information from meters are
retrieved every day.
Typical performance level is well over 99,5
% calculated of a time period of 96 hours.
Major reasons not reach 100 % is mainly
for power line communication:
- noise or disturbances on the power line.
- rebuilding of the power grid.
- power failure (the customer turns off the
power in such a way that the communication
are interrupted).

And for radio communication weather sensitivity is the most common disturbance.
Lack of coverage in the GSM/GPRS-network still influences on the performance but due to
the combination with PLC or radio this problems are manageable.

8. System Security

Initial setup of the communication solution was just an information delivery, but with two-way
communication to enable remote system upgrade etc.
With the delivery of smart meters from NES (Echelon) it was possible to include the option
for remote switching on/off of customers.
This switching-functionality induced improvement of system security that we just now is
utilizing by for example:
• Reducing internal access by partitioning the network
• Patching of servers, improve patch management
• Close down unnecessary communication
• Improve functionality in Disaster Redundant Solution

10. Metering vs Street Lighting in Sweden
Confidentiality - None (C1)
Vattenfall Smart Meter Project in Sweden | E Nordgren | 2015.06.1710
Metering
No of residential customers: 5 200 000
Average consumption per customer: 8 000 kWh/year
Not only for measuring but also part of Smart Home
Street Lighting
No of street lights: 2 000 000
Average consumption per streetlight: 750 kWh/year
Not only for control but also for Smart City Soultions

11. Summary and conclusions
• Same type of challenges for Smart Street Light as for Smart Metering.
• More than 15 year of experience from Smart Metering can be reused.
• Less energy value handled require special designed pricing models.
• But it might be so that we need legislation really to push for a broad
implementation of Smart Street Lighting in Sweden as well as in Europe.
