WHAT MAKES THE GRID SMART?

“Digital technology that allows for two-way communication between the utility and its customers, and the sensing along the transmission & distribution lines is what makes the grid

smart. Like the Internet, the Smart Grid will consist of controls, computers, automation, and new technologies and

equipment working together, but in this case, these technologies will work with the electrical grid to respond digitally to consumers’ quickly changing electric demand”

-US Department of Energy-

TNB Journey Towards Smart Grid


UiTM Shah Alam

For TNB, prioritizing the initiatives is done with four objectives in mind – all revolving around the customer

Optimizing capex and opex spending to

minimise long term increase in tariffs

“Value for money”

power quality and

network reliability

improvements

Improve overall

customer

experience and

enable delivery of

new products and

services

Manage new complexities in grid

operations (e.g., with RE) and enable

beyond the kWh plays

• Plan, develop, operate and maintain TNB’s500kV, 275kV and 132kV transmission network

• Transport bulk power from power generators todistributors and to large industrial customers.

• Transmission critical task is to “Keep The LightsON” by ensuring adequate, secure and reliablepower flow across the network to meet thegrowing electricity demand.

• The National Grid is interconnected in the northto Thailand’s EGAT transmission system via the300kV HVDC interconnection of 300MW capacityand 132kV HVAC double circuit overhead line of90MW capacity each and in the south, toSingapore Power’s transmission system via two230kV submarine cables of 200MW capacityeach.
