All CONPIINATION OF STIIEEfLLGMf CHANGEOVER PROGRAM
Di,
This is to follow up on our recent discussion rega ing the continuation
and possible acceleration of our streetlight changeover program.
Efforts to date have resulted in the replacement of all but approximately
30 of our 400 watt and 250 watt mercury vapor fixtures, plus nearly %00 175 watt
meroury fixtures with lower power high pressure sodium unite. Me 30
remaining large fixtures will he changed shortly with N.P.S. units in inventory.
This leaves approximately 1,210 existing 175 with mercury vapor fixtures which
should be replaced with 100 watt H.P.S. to finish the program.
The estimated coat for purchasing the remaining 1.200♦ H.P.S. fixtures Is
out $60,0001 however, the Electrical Division is currently doing a city-wide
survey for elimination of some streetlights in areas considered to be
excessively illuminated. Depending on the extent that elimination occurs, we
would likely only have to purchase. around BOO new fixtures at a coat of
approximately $40,000.
Changeover of remaining mercury Vapor lights should be accomplished as
as possible because the City would realize savings more quickly, Anal The
"payback" period would be ahortened due to liklihood of electrical power costa
rising Imre rapidly than Changeover costa.
The changeover process requires aur bucket truck and two men. This crew
is able to change 80 to 100 fixtures par week — if not interrupted. However,
the bucket truck is frequently required for other necessities Such as repairing
1funotloning traffic signals. I would, therefore, estimate that an average of
60 fixtures par week could be changes. On this basis, it would take three months
to change 800 fixtures. Delivery time for new fixtures series, but I would
anticipate that this work could start by May 1, if Bide were advertised fairly
Emceed on the foregoing assumptions, energy cost savings are estimated tu
be as followai
