Offices ELECTRICAL POWER Approximately 930 GWh
of hydroelectricity, 200 GWh of combined heat and
power, 4 GWh of biogas electricity and just over
30 GWh of wind-power-generated electricity are
produced in an average year (from
2007). Hydroelectric power stations 1

... Rönnöfors ELECTRICITY NETWORK The length of
the grid is 7,971 kilometres, of which 588
kilometres are regional networks, 3,216
kilometres are distribution networks and 4,167
kilometres are low voltage networks. There are
2,580 network stations and 40 transmission and
distribution stations in the grid. Combined

HEATING Jämtkraft has district heating operations
in the following locations Östersund, Brunflo,
Ås, Krokom, Nälden, Föllinge, Järpen, Mörsil,
Åre, Duved, Kall and Hallen. It produces
approximately 645 GWh in an average
year. District heating plant TELECOMMUNICATIONS
Jämtkraft provides broadband to companies,
property owners and private individuals. The
optical network is approximately 3,000 kilometres
long. Current broadband network Planned

Background of the cooperation SAMS

• User defined development rather then supplier
  defined.
• Build a knowledge base, within the companies not
  educate concultants.
• Possibilities to share recourses, for example,
  for example during summer vacations, spare parts
  pooling, installation manpower etc
• Advantage of scale- better price, stronger in
  negotiations for an agreement
• Try to avoid vertical integration from the
  suppliers and open up the systems

11
The new Generation of Meters Basic vs. the
New Generation
Functionality
N.G.
Basic

• Correct Invoice, Change of supplier,
• Monthly values
• Time of use, hourly values
• Power tariffs
• 2-Way communication
• Interruption info on low tension
• Direct read Online
• -Remote connect and disconnect of
  customers
• -Control of external load

Why NG-meters

• Increasing customer demands
• Outage info to reduce outage costs
• Active load control
• New tariffs, tariff optimization
• Develop a more efficient utiity
• Assetmanagement
• Netcontrol, reduce losses, circuit/equipment
  engineering analysis
• Systemload analysis
• Administrationdevelopment-reduce losses improve
  effiency
• Customerservice
• Energysaving

SAMS-North

• NG meters
• Interoperability
• Common multivendor softwaresystem for
  meterreading.
• Our communication choice is primarly PLC-MV.
• Common Data Base software
• Hourly values
• 2-way communication

16
Why MV PLC

• GSM/GPRS isnt covering our network in many
  places.
• Topological reasons makes radiocommunication too
  expensive to cover all the network
• Few customers under many MV/LV substations makes
  LV PLC expensive
• Remains PLC-solution from HV/MV substation(11
  eller 24 kV) down to customer on LV as
  communication choice.
• By using MV PLC you have long term control over
  costs and quality trough communication on yuor
  own network

MV/LV PLC

• Open standard protocols and communication
  interfaces
• Known flexible technology
• Interoperability hybrid systems

20
Experiences

• Every network har their own techincal problems to
  solve and adjust the plc-equipment to
• You must have the plc-communication equipment
  installd before you install meters
• Solve upcoming problems immediately
• Approx 3 of installations need more than 1 vist
  at customer site

21
Future outlook

• IP-based AMM down to a IP meter over PLC
• Net metering
• Extend scada systems down to the breaker at the
  customers meter
• Integrate AMM with energy end-use and energy
  services
• Separate metersadministration and AMR from
  Billing systems
