Ageing infrastructure (generation, transmission & distribution systems) . Energy crisis (energy security & costs) Coal . Financial crisis (grid reinforcement becomes unaffordable) . Environmental crisis (green house gaseous) • They occur simultaneously TNB’s case; TNB’s long term strategic plans • TNB’s 25 years Electricity Technology Roadmap (TRM) , with a purpose of modernising electricity supply industry in Malaysia • TRM focuses on 4 main goals: . Reliable and efficient delivery system . Intelligent power-delivery systems . Value-added electricity products and services . Enhanced environmental management • The actions to go ahead is now 10 TRM sets TNB’s journey towards smart grid Year 2004 Year 2005 Year 2007 TNB Technology TNB Research TNB Technology Roadmap (TRM) 1 Technology Roadmap Roadmap 2 • Overview of 25-year Electricity • Align TNB 20 years Strategic • Technology options derived TRM for the electricity supply Plan and TNB TRM from TRM 1 industry (2004 – 2030) • 1st Destination (2006-2010) - • Detail out action plan of chosen • 4 themes in the TNB Electricity 18 research programs have technology options TRM been created to ensure long • 6 technologies identified: •Reliable and efficient term and progressive effort to • Improve combustion delivery system improve the TNB power efficiency •Intelligent power-delivery delivery system and 11 Niche • RBI systems Technical Services will • IEC 61850 •Value-added electricity spearhead the company • WAIS products and services towards business expansion • DNIM •Enhanced environmental • 2nd Destination (2011-2015) – • CRM management 4 Advanced Research Program and 2 Specialised Technical Services have been identified TNB TRM sets up the foundations and goals for near and long terms 11 TNB’s TRM destinations 4 2030: Breakthrough Energy Conversion Technologies & Sustainable Development 2020: Smart & Intelligent 3 Electricity Delivery Management 2015: Robust & 2015: Enhanced Electricity Resilient Power Products & Services Delivery System 2 1 2010: Reliable Electricity Supply 2004: start 2010: Efficient Electricity Production & Delivery 12 Progress of foundation work so far TECHNOLOGY IDENTIFICATION IMPLEMENTATION STATUS AREA OF IMPLEMENTATION Risk Based Inspection (RBI) Implemented (as part of TRM2) Generation Condition Based Monitoring (CBM) Masterplan was completed.
