Right night lights on Western Cape N1

Copper theft and vandalism make it impossible to rely on a purely reactive maintenance process to keep critical systems running. With South Africa’s rolling blackouts, tariff increases and requests to ‘switch off’ to save energy, the sight of streetlights burning throughout the day, is a sore issue.

The telemanagement system, designed for the effective and efficient management of public lighting networks, puts control back into the hands of public lighting and infrastructure managers.


 The South African Electricity Regulation Act (4.2006): Electricity Regulations for Compulsory Norms and Standards for Reticulation Services enforces very specific requirements for the adoption of energy efficiency practices in public lighting, for example:

“(a) In respect of lighting:

(ii) Street and highway lighting must be energy efficient and licensee must ensure that it is switched off during the day;
(iii)Streetlights must be fitted with systems that allow for remote reduction of power especially during capacity constraints.”

It further states that: “The Energy Act (2008) will be used to implement regulations on the management, measurement and reporting of energy efficiency.”


 Take note

  • Streetlighting is required to be energy efficient and it should be possible to reduce the power usage remotely.
  • Various systems exist to allow remote control of lighting loads.
  • Modern lighting control systems use wireless mesh network technology.
