When might an SSU or 11kV supply be required?
This depends on the requested load, network conditions, site constraints and the supply scheme offered by TNB. A load and site review is required before conclusions are made.

Frequently asked questions
Can you calculate the proposed maximum demand?
Yes. We can review the equipment or tenant load schedule, diversity assumptions and operational requirements to prepare an appropriate demand assessment.
Can approval or energisation dates be guaranteed?
No. TNB determines the supply scheme and programme based on technical, network and commercial requirements. We coordinate the application and help address the technical requirements efficiently.
