Renewable Energy and Security of Supply A view from a TSO 23.September.2009 Francisco Saraiva Cigré’s International Colloquium
Sustainability& NewEnergyParadigm • Role ofElectricity • RenewablePower • Role oftheGrid
Security of supply Competitiveness Climate change SUSTAINABLE ENERGY The Key Drivers OIL/GAS IMPORT DEPENDENCY Business as Usual is unsustainable TOTAL COST OF ENERGY CO2 EMISSIONS
SECURITY OF SUPPLY Primary energy sources Adequacy of supply systems

TRADITIONAL ENERGY SOURCES: OIL Conventional oil reserves. Countries with > 1 Gt oil reserves Source: BGR • Priceshighly influenced by numerous factors (extraction and refining capacity, availability of resources...) • Production’s growth might stop in 10-15 years
TRADITIONAL ENERGY SOURCES: NATURAL GAS Regional distribution of estimated ultimate recovery of conventional natural gas(2007) Source: BGR • Priceslinked to oil • High efficiency of the electricity production technologies using NG (CCGT) • Environmental friendly energy (comparing to coal and oil)
TRADITIONAL ENERGY SOURCES: COAL • Abundantandworldwide distributed Proven reserves (10 biggest producers) Source: WEC, SER (2007) Reserves estimated in 150 years, at current consumption rate • Relatively stable price • According to the International Energy Agency (IEA) coal will be the primary energy source with the higher growth until 2030 • But ....a major CO2 emitter
The traditional fossil energy resources are limited Alternatives are required ….
ENERGY SCENARIO is CHANGING all over the World EUA: American Clean Energy And Security Act European Union: Energy and Climate Package G8, IEA Outlook, COP
«Current global trends in energy supply and consumption are patently unsustainable - environmentally, economically and socially. .... What is needed is nothing short of an energy revolution» World Energy Outlook 2008- International Energy Agency (IEA) 12.Nov.08
The New ENERGY PARADIGM • Energy Efficiency • Endogenous and Renewable Energy Sources and other Low-Carbon technologies
Sustainability & NewEnergyParadigm • Role ofElectricity • RenewablePower • Role oftheGrid
Demand Side • LESS ELECTRICITY WHERE POSSIBLE(electricity savings) • MORE ELECTRICITY WHERE NECESSARY(more efficient processes; new uses) Industry PHEV Rail transport Household Appliances Motor Systems Heat Pumps Lighting
Supply Side Towards low-carbon power generation and new technologies in electricity supply Fossil Fuels Low-Carbon Tech. Renewables
Energy Efficiency (demand side) Renewable Power (supply side) + Security of Supply (less dependent on energy imports) + Environment Protection(less CO2 emissions) Electricity Sinergies + Sustainable Energy

More RENEWABLE ENERGY Grid Expansion/Reinforcement Huge Investments • New lines • Reinforcement of existing lines; • New substations (receiving wind) • More transformation power • More reactive energy compensation capacity • Control and command equipment modernization In the future: One-way transmission systems (from power plants to consumers) or … a different model?
SMART GRIDS The new Grid model paves the way for the integration of distributed generation (renewables and other micro-generation, …) and “consumer side” applications (demand response, home made energy, …) Source: “Smart Gris – Vision and Strategy for Europe’s Electricity Networks of the Future”
SMART GRIDS BENEFITS “Updating the way we get our electricity by staring to build a new SMART GRID that will save us money, protect our power sources from blackout or attack, and deliver clean, alternative forms of energy.” U.S.A. President Barack Obama, 2009 • New uses of the electric grid (operation and “consumer side” applications) • More distributed generation can be integratedwith the grid • Mass-scale renewablesintegration • Consumer incentive for efficiency
