1 Power Transmission Lines Are there alternatives? Denis Imamovic, Head of Power Transmission Lines siemens.at/future-of-energy

2 The business environment is in transition Need for efficient bulk power transmission and flexible operation Grids in transition Energy autonomy Support-policies for renewable energy Cross border interconnectors Declining revenues Investment risk for new technologies Investing in automation vs. improving hardware Huge installed (aging) assets Energy efficiency directives demands Underground bulk power lines investment Integration of municipalities (electricity/gas/heat/water) Demand response vs. demand management Involving prosumers through Smart Metering Unbundling and privatization Improving supply of powercritical consumers Affordability of grid automation New power lines and capacity expansion Growing grids Page 2

3 Today s main challenges of the energy system Economic efficiency Reliable power supply Climate protection Resource efficiency Acceptance Over the past century, affordable energy has been a significant component of global economic growth and development. World Economic Forum Inefficient, antiquated energy supply stifles productivity. United Nations Foundation,»Achieving Universal Energy Access«Europe will cut its greenhouse gas emissions by 40% by 2030 and will produce 27% of its energy from renewable sources. The Guardian Decentralized generation will call for changes to the electricity network and, to ensure flexibility, the power sector will need to become more intelligent and computer-controlled. Kelvin Ross, Power Engineering International The concept of achieving public awareness, positive experience and acceptance as a prerequisite for the successful full scale roll-out of a smart grid has not only delivered a positive stakeholder response 2013 Global Impact Report Page 3

4 Growing share of renewables and distributed generation calls for transmission grid expansion More electrification Further development of electrification levels in emerging economies Grid modernization required in many regions Distributed generation Increasing level of renewable and distributed generation Grid stability challenges Page 4

5 Energy system changes and grid development requirements differ from country to country Development cycle of energy systems Level of maturity DE CN IN Time (Basic-) Electrification Industrial Growth Energy Efficiency Change in generation mix Extension of capacities for power generation Distance between generation and consumption Decentralization (public/ private) Example India Increasing power demand mainly covered by coal plants New grid access and integration of renewable mainly in North / West India Focus: Reliable grids, e. g. extension of transmission capacities Example Germany More renewable generation Integration of distributed renewable resources and grid access of large offshore wind parks Focus: Extension of transmission grid / stability / grid integration Page 5

6 Sustainable energy supply: Solutions for grid reliability and resiliency Challenges Goals Solutions Urban infrastructures Grid development Complex Exploding digital data volume systems Compact and reliable power corridors Public acceptance Security of supply Interoperability IT security GIL, GIS, low noise transformers Compact transmission lines Standardization Open control architecture Product and process security hardening Economic pressure CAPEX/OPEX optimization Asset management Variable power flows and bulk power transmission System stability and efficiency Forecasting and resiliency Power electronics HVDC/FACTS Digitalization Page 6

7 Pushing the integration of infrastructures Central Large Utilities Application cases by location of storage Decentral Small utilities, municipalities, industry prosumer Pumped storage H2 Battery Thermal Electricity Electricity H2/ Methane H2 Fuel (gas grid) for car Grid balancing and stability Power-to-gas Power to value Electricity Grid stability and self-supply Heat (power) Power-to-heat Page 7

8 Electricity highways How to do? Overhead Lines Cables Compact transmission lines Page 8

9 Compact transmission lines enable for highest transmission capacities at very low losses Page 9

10 Compact transmission lines are used in three main applications 1 Transmission lines (between two pylons) 2 Hydro power plants vertical GILs 3 Substations and conventional plants Page 10

11 Electricity highways there are no alternatives! Compact transmission lines as one solution for the balance in the magic triangle Affordability / economic efficiency Highest efficiency transmission and long lifetime Environmentally friendly SUSTAINABLE ENERGY SUPPLY Availability / security of supply Low land usage & low external electromagnetic fields High reliability and high safety (no fire hazard) Page 11
