Energy and Environmental Challenges for the Metering Industry
Paolo BertoldiEuropean Commission DG JRC
Ispra 7 March 2005
2Ispra 7.3.2005
The EU Energy Policy Key Areas
security of supply
climate change and sustainable development
effective competition and creation of an internal market
3Ispra 7.3.2005
Two Neglected Energy Sources
To improve the security of supply and meet the international climate change obligation there is the need :
– To foster the penetration of renewable energy sources;
– This shall be accompanied by a prompt action on the demand of energy through a sharp increase of the end-use energy efficiency;
4Ispra 7.3.2005
The draft Energy Service Directive
• EU security of supply and Kyoto Commitment.
• EU savings potential >20%; 1%/yr target possible in all M.S.
• Demand-side not addressed in Internal Market Directives.
• Need for umbrella for existing & proposed energy efficiency legislation (EPBD, CHP, Eco-design, etc).
• Also need for harmonisation of energy efficiency & energy services in internal market.
5Ispra 7.3.2005
The draft Energy Service Directive - Content 1
• 1 % annual overall target (Article 4):
- cumulative to 2012; 6 years (6-yr target discussion).- target amount fixed for period; independent of GDP. - early actions (1991) allowed; (discussion on start date). -allows impacts of information, building codes, tax changes; (double-counting an issue ). - annexes: guidelines on M&V (standards? committee?).
• “white certificates” later. (need harmonised M&V!).
6Ispra 7.3.2005
The draft Energy Service Directive - Content 2
• 1,5 % annual public sector target (Article 5):- a sub-target of the overall 1 % target (PS=10%).
- uses same methodology as overall target.
- uses aggregated public procurement to increase demand for energy efficiency & energy services.
• Precise definition of ”public sector” important.
7Ispra 7.3.2005
The draft Energy Service Directive - Content 3
• Obligation for some energy distribution and/or retail energy sales companies (Article 6): - to offer energy services or energy audits (electricity, gas, district heating and heating oil).
• Enterprises to help remove market barriers. • If 5 % of customers not covered by services, free
energy audits (under discussion; likely to change).
• Information from enterprises to public authorities to promote energy services & energy efficiency.
8Ispra 7.3.2005
The draft Energy Service Directive - Content 4
• Qualification, certification and accreditation of energy service providers (Article 8):- ensures technical competence & mutual recognition.
• Financial instruments (Article 9):- third-party financing, energy performance contracting & similar instruments promoted.
9Ispra 7.3.2005
The draft Energy Service Directive - Content 5
• Tariffs & regulations net-bound energy (Article 10).- tariff structures to weaken volume incentive link.
• Cost recovery for distribution companies, if reasonable, fair & if competition ensured. (Possible market distortion effects under discussion.)
10Ispra 7.3.2005
The draft Energy Service Directive - Content 6
• Financing of energy efficiency programmes, measures, ESCOs etc. allowed (Article 11).
• Opens funds to all providers of energy services, energy efficiency programmes & measures, without prejudice to State Aid rules.
• Energy audits (Article 12):Member States to ensure the wide availability of independent energy audit schemes.
11Ispra 7.3.2005
The draft Energy Service Directive - Content 7
• Metering & informative billing (Article 13):
- Ensures accurate metering of net-bound energy, actual consumption & time of use. (Small customer coverage discussion.)
• Member States to ensure frequent & informative billing from all energy suppliers; information on benchmarks, available energy services & measures. (Branch organisations helpful.)
12Ispra 7.3.2005
The draft Energy Service Directive - Content 8
• Reporting (Article 14):-M. S. report not later than 2 years after adoption of Directive & then every 3 years up to 2012.
(Discussion on interim and final reports only.)
-Commission to report on progress toward achieving national targets.
• Transposition (Article 16):- by June 2006.
13Ispra 7.3.2005
Current Status of Discussions
• Discussions on-going in Council & E. P. Mixed but mainly positive reactions. Concern with targets & measurement.
• Luxemburg's Presidency will give proposal appropriate attention. Possible political agreement in 2005.
• May form committee to harmonise measurement & verification.
• Metering and billing important to provide accurate and timely
information on energy end-use. These are vital sources of information that promote energy efficiency and energy services.
14Ispra 7.3.2005
The Challenges for Metering and Demand Response Initiatives
Advanced Metering and Demand Response Initiatives have the capacities to meet all three the energy policy goals of the Union, however there is the need to make sure that Regulation and Policy direct the technology potential in the right direction.
15Ispra 7.3.2005
The role for ICT and Meters
Good examples of the available technologies are:
real time meters which would allow the users to know the price and environmental impact of the electricity the are using;
intelligent appliances and equipment which would allow to maximise the energy savings;
building control systems designed to minimise energy use and the maximise wellness of the occupants;
16Ispra 7.3.2005
Advanced Meters
The evolution of Power Line Communication, Internet, and ADC technology for Energy Management have permitted the AMR (Automatic Meter Reading) solutions to reach high competitiveness capable of guaranteeing not only automatic reading of consumption but also the ability to offer the domestic user new services necessary for optimising energy consumption and respecting the environment.
17Ispra 7.3.2005
The ENEL “Digital Meters”
18Ispra 7.3.2005
The “Digital Meters”
What the end-user should be able to do:
• check the total consumption (KWh) over a period
• check the instant absorbed power (KW)
• have the possibility to compare the last week/month consumption, with other period and check if it is increasing/decreasing
• understand the consumption of individual appliances;
19Ispra 7.3.2005
Additional desirable features
• To indicate the type of electricity used ( to serve for the full disclosure and Guarantee of Origin, Tradable Green Certificates, etc.);
• To guide the user to save energy, power and maximise the use of renewable energies by providing first of all information;
• To receive and sell White Green certificates, if they exist;• To allow to participate in real time demand side bidding;
20Ispra 7.3.2005
What should an advanced meter able to do ?
• In the home, the meter could become an “intelligent home gateway”. It can act as the two way interface between the external service centre and home appliances or systems and generate related graphic or aural feedback to the user through a dedicated display or the television receiver or the PC monitor. An immediate low cost solution for millions of homes in many European Nations would be the use of the subscription satellite or cable Digital TV interactive network
• The meter can readily supply data to the display of energy usage which profiles, lighting, heating, wet appliances and cold appliances. The careful presentation of this information can reduce energy consumption.
• A small scale UK project, in which homes were fitted with a display screen giving a clever presentation of total energy usage, recorded a sustained 10% average energy requirement reduction for all homes (Source: Bob Harrison).

Conclusions - 1
• The environmental and energy challenges requires a new ways of using in the most intelligent way the limited energy sources (in particular RES);
• The economic efficiency and increased demand for green electricity and its efficient use requires more advanced control systems and meters to optimise the energy services (lighting, cooling, heating, washing, entertainement, etc.) to the the limited energy sources;
25Ispra 7.3.2005
Conclusions - 2
Regulations and Technology Deployment Programme shall foster the develop of new, cheap and reliable technologies and systems to allow the efficient and cost-effective decentralized control and management of the energy demand for the services and the environmental conditions (indoor temperature, lighting) which we need.
Today we are here to discuss:• the technologies;• the R&D needs;• the user and utilities expectation from the advanced meters;• the present barriers to their large deployements; and • the best solutions to remove these barriers
