MEETING OF SOUTH DUBLIN COUNTY COUNCIL

Monday, September 09, 2019

QUESTION NO. 22

QUESTION: Councillor Sandra Fay

To ask the Chief Executive if South Dublin County Council has looked investigated the cost and feasibility of switching to solar power street lights as a longterm future solution, as opposed to continuing with LED replacement?

REPLY:

We have investigated this technology for use in public lighting applications for the county. There are still efficiency issues associated with this type of installation given the relatively high power requirements of each public lighting column and the amount of power that would be available via a solar array/battery electrical supply configuration. This would be a particular problem in the winter, given the shorter days and longer nights.

In the event of a resolution of the supply issues above, this technology would be seen as an addition to, rather than replacement of, our LED Upgrade Programme and evaluated on that basis.
