SMART GRIDS PROJECTS IN EUROPE THE BIG PICTURE More than 450 projects 221 ongoing 578 Implementation sites 1750 Organisations 3.15 b total Average budget per project 7.5 M Largest investors: UK, FR
SMART GRIDS PROJECTS IN EUROPE THE BIG PICTURE Good degree of application diversity Smart network management and smart consumers/homes are the most targeted New control/automation system consolidated Distributed ICT for DER/flexibility Density of implementatiion sites weighed by budget EU 15 concentrated most of the activity Some interest on East side but small budget allocation
EUROPE: LESSONS LEARNED SMART GRIDS LANDSCAPE Projects not evenly distributed (EU15 doing most of the job) Many projects focus on integration of technologies and applications Fundamental role of the DSOs / TSOs Deployment cover most of investments (7% of projects 60% of investments) LARGE SCALE MULTIDISCIPLINARY DEMONSTRATORS Large scale demonstrators, involving high number of sites and communities needed to prove up-scaling and reliability of solutions Incresaed complexity of electricity system requires multidisciplinary consortia to integrate competences and share risks SET UP OF MARKET PLATFORMS FOR THE PROVISION OF SERVICES Revise incentives model to accelerate innovation uptake and encourage to move towards a service-based business model Most of smart grids benefits are systemic in nature service-based market platforms are essential to attract operators
EUROPE: LESSONS LEARNED CONSUMERS Need to have trust to harvest benefits from smart grids technologies and applications; Consumer engagement is crutial to development of electricity services platforms; Consumer segmentation is very important to taylor energy services, target early adopters, guarantee different levels of engagement. INTEROPERABILITY, DATA PROTECTION AND DATA SECURITY Open and secure ICT infrastruture is core for smart grids implementations; Convergence towards IP communications and other standard-based solutions; Energy and ICT communities need to work together to coordinate security measures, avoiding blind spots; Data protection and security not yet sufficiently addressed by the projects. Experience from other sectors is needed. Privacy-by-design approach
USA: APPLICATIONS OF DOE «SGIG» PROGRAM (SMART GRID INVESTMENT GRANT) DOE SG private induced investments: $4500 million SGIG program: $3425 million
USA: IMPLEMENTATION SITES
USA: LESSONS LEARNED Reliability Automated feeder switching: Reduction of frequency of outages, number of customers affected by sustained outages and momentary interruptions, total amount of time without power Automatic control VVO: Voltage and VAR control Optimization: Reduction of line losses by 5-10%; Peak demand reduction by 1-2.5%. Advanced Metering Infrastructure Cost reductions and productivity improvements related to reductions in labor and vehicle costs; Less problems between systems and customers for projects with preceding experience in smart meter deployment. Demand Demand reductions from the application of Advanced Metering Infrastructure, pricing programs and customer-based systems.
BRAZIL: APPLICATIONS OF SG PROJECTS $60 billion 2010-2013 Projects of distribution utilities supported by government and regulator Research and Development Energy Efficiency Government Fund Distribution 0.2% 0.5% 0.3% Transmission 0.4% - 0.6% Generation 0.4% - 0.6% income % to SG by law Smart metering and AMI (concentrators) T&D automation (fault detection, Volt / VAR control, automatic dispatchment) Demand response Electric vehicles Remote management systems for residential customers
BRAZIL: LESSONS LEARNED Smart meters Important reductions in total losses through advanced metering systems (meters and concentrators). Focus: Government heavily focused on investing in improving energy efficiency and sustainability. Subsidies and incentives: National subsidies and incentives to assist Brazilian companies and technology institutes to develop innovative technologies for power sector (solar power, smart grids, energy-efficient vehicles, ). Business: Great opportunity to R&D and to do business in Brazil in both energy sector and Smart Grids
CHINA: APPLICATIONS OF SGCC PROJECTS STRONG AND SMART GRID PLAN (SGCC-STATE GRID CORPORATION OF CHINA) 2009-2010 2011-2015 298 pilot projects concluded: 4.8 b invested. 70 GW wind; 16 GW PV

CHINA: LESSONS LEARNED Motivations of the good results in network and SG development RES: Acceleration of SG development to efficiently connect renewable powered electricity into the grid. Timing: Advantage of building Smart Grid technology into transmission infrastructure from the outset. Regulation: Facilitation of regulatory systems due to enormous size of state-owned transmission companies. Economy of scale: Economy of scale that helps to reduce costs and spark domestic manufacturing of Smart Grid equipment. Government support: Support of the government to efforts of domestic and foreign Smart Grid manufacturers through subsidies, R&D funding and major lines of credit.
CONCLUSIONS Prominence in each country SG vital part in government strategy to achieve common goals of energy security and low carbon economic growth Smart meters first measures used and deployed: present deployment level depends on development stage of the country T&D control needs similarities in T&D control needs between more and less developed countries in integrating interconnections and distribution network for upgraded or new plants and lines Advancement Japan and South Korea most advanced in SG development thanks to good performance of electricity systems, thus devoting efforts to customer side applications Government support need for governments to put strong efforts and investments in development of SG applications, and mainly in demonstration projects, and that local authorities support start of initiatives
