MESSAGE FROM
HIS WORSHIP THE MAYOR,
COUNCILLOR A . H . HONIKMAN , F. R.I. B.A ., J . P.
In Ihis conlempOfllry world eleclric power Is Ihe lifll-blood
of a nalion. No CIty can prosper with eledllClty In shol"1
supply. Indeed the rate of Incleese in energy generated is
the measure of a CIty'S growth
What is tM posit,on in
Cape Town?
The year 1895 saw the erectIon 01 the C,ly"1 Ilrst power
stat,on at the Molteno reserlo"
capaCIty of only 300
~,Iowa"s
In
Oran lelIChl w,th a
To-day wIth Ihe opening of
Ihe Athlone Power Station. the Cllis power plant capacIty
has grown 10 320,000 ki lowatts
more than 1,000 times
whal it was 67 years ago. Thi' progress. coupled w,lh low
production costs, IS a source 01 justir,able pride 10 all
concerned
It is not generally known Ihat a clly's eleClrlClty needs
must be an ticipated apprO~lmately se.en years in ad.ance
If power famine Is 10 be avoided ThIS enla,ls foresight
and Inlilall .". and I pay lIibute 10 Ihe OapuT)' Mayor, Councillor W. J. Pelers, J.P .. Charrman of Ihe Electricity C;:ommlttee, and col leagues serlIn" under him; Mr. C_ G. Downie, Ihe City Electrical Engme", ; Ihe Consuilanls _tJessrs.
Merl and McLellan of London and Messrs F E KanthaCk
and Partners of Johannesburg. and, Indeed, all who ha."
contributed to the de_"topmenl of th" City's EtectriClty
Und"rtakln,. and Its reputation for efficiency_
