Background
• Transition towards a sustainable energy system puts requirements on the electricity network. Adaptation of the electricity network to this transition is needed:– Enabling an increased integration of renewable
energy in the power system– Reduction of peak load– Supporting a more efficient use of energy– Allowing more active customers

Need for flexibility
• Production changes at a faster time scale than the network can adapt using existing technology.
• Any new technology that can offer increased flexibility has a clear advantage above existing technologies.

How do we define smart grid?
• Smart grid or intelligent network: the collection of new technology, functionality and regulation on the electricity market that cost-effectively – enables integration and use of renewable electricity
production, – contributes to power reduction during peak load,– results in more efficient energy consumption, – and creates conditions for more active customers –
including the implementation of demand response.

The Swedish Coordination Council for Smart Grid• Appointed by the Swedish Government in May 2012• The council consists of 15 members with key positions within
industry, governmental authorities and academia• Mission
– Coordinate and stimulate cooperation and knowledge transfer between different actors in the area of smart grid and deliver proposals to accelerate the development of smart grid in Sweden
• Specific obligations– Create “dialog forums” for specific issues within the area of smart grid with a
broad stakeholders involvement – Create a knowledge platform to gather and spread knowledge on research,
development, demonstration and innovations etc.• Link to smart meters (hourly reading and two-way communication).• Link to a number of demonstration projects to start in the near future
• Final output– A national action plan to remove further barriers against the introduction of smart
grids – final report by December 1, 2014

Energy efficiency - smart grids and smart meters
Samordningsrådet med kunskapsplattform för smarta elnät
Smart grid enabling a more efficient use of energy• Reduced losses in the network (out of 150 TWh
consumption)– 2.8 TWh in transmission (1,8 %)– 2.3 TWh in subtransmission (1,53 %)– 3.9 TWh in distribution (2,6 %)
• Electrification of the transport sector• Energy efficient consumption
– Feedback of consumption to the customers; on a monthly or hourly basis.
– Economic incentives for energy efficient investments– Research on how to inform customers to change their
consumption patterns.

The Swedish electricity market and the implementation of smart meters
• Market opened since 1996• 130 suppliers and 170 grid companies• From July 1 2006; Mandatory hourly meter
reading for all customers above 63 Amp; before above 200 Amp
• From July 1, 2009; Mandatory monthly meter reading for all customers (5,2 million)

Main drivers behind the new legislation• Billing was considered to be a major problem
by customers and also the number one complaint
• No more yearly estimates – customer should receive bill based on actual consumption
• Main driver for the new legislation was to provide customers with regular feed back on their electricity consumption to increase awareness and promote energy efficiency

Prerequisites for more active customers
• Cost reflective tariffs • Distinction between electricity price and
network tariffs• Possibilities to choose between
– Different suppliers– Different services or contract with the same supplier– Impact electricity costs by shifting consumption in
time

Smart metering roll-out 1(2)
• The DSO is responsible for meter reading –– very costly to do manual meter readings every
month
• The new legal demands lead to a major roll-out of remotely read electricity meters
• 99 % of all meters was replaced by 1st of July 2009

Smart metering roll-out 2(2)
• No actual legal demands on minimal functionalities as of now– Except on data storage
• What kind of meters have been installed?– Early interviews and estimates with the DSOs
indicates that almost 90% of the meters are able to handle hourly read meter values
– Survey made by Energy Markets Inspectorate during 2010; about 90% capable of hourly meter reading etc.

Communications systems
• No legal demands on communication systems/interfaces– Two way communication, displays etc
• Majority of the meters are connected to communication systems that can transfer hourly meter values
• Majority of systems capable of two way communication

Next step
• According to a recent parliamentarian decision network companies will be obliged to deliver hourly meter reading if customers demand it, starting October 1, 2012
• Activities with the aim to allow customers to react actively to price signals from the markets and to stimulate demand response to reduce peak load – Specify requirements on the functionality of smart meters and
the information provided to customers– Investigate the need for changing the structure of the network
tariffs – Investigate the benefits of deregulating the meter market
