TNB’s main concerns on planning

Coal

• Electricity demand growth continues – 3.5% for next 10 years – 2.7% for next 20 years

• The local natural gas resources as “clean” fuel is depleting

• It will be replaced by coal, until nuclear option is available in

post 2020• There are serious concerns on CO2 emission, increasing

dependency on fossil sources and lack of RE, EE & DSM andincreasing consumer expectations

• There is urgent need to increase operational efficiency i.e.there is need to increase utilisation of transmission anddistribution assets and to reduce system losses

Opens opportunity for harnessing the benefits of smart grid



1010

Drivers for developing TNB’s smart grid

Coal

Global trends• Development of smart grid is driven by 4 factors :

Ageing infrastructure (generation, transmission & distribution systems)

Energy crisis (energy security & costs)

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

Conclusions

•

Growing demand and limited resources while maintaining tobe environment friendly impose severe pressure to TNB in itsplanning. Smart grid is an option towards a workable solution

• TNB has decided to embark on implementation of smart gridtest system projects. It will be carried out in 3 phases

(2010~2013) at 3 sites; Bukit Bintang in Kuala Lumpur, BayanLepas in Penang and Medini in Johor.

• TNB desires to gain valuable experience from the smart gridtest systems so as to lead to successful implementation of

smart grid in other parts of TNB power grid system.• Research are required for some applications in order to

ensure only the right technology is deployed for the purpose.
