Photo of the Week
January 21, 2018
The story of the Gatun hydroelectric plant continues with new developments this week:
After the Gatun spillway and hydroelectric plant were
finished in 1914 it became evident that
this current hydroelectric plant was too small to accommodate all
that it was intended to support the canal and surrounding areas. Willis
J. Abbot, Author of The Panama Canal An Illustrated Historical
Narrative of Panama and the Great Waterway Which Divides The American
Continents - 1917 summarizes what the Gatun Hydroelectric Plant was
intended to provide power to.
When they pulled the switch in 1914 to send the power to all,
there wasn't enough power. Poor
planning or bad forecast to blame?
I think the planning part was good as there were provisions to
enlarge the hydroelectric plant if needed.
This was addressed in the articles I provided from the Canal
Records last week. Well, this
is what this week's photos are all about. Within just two years,
the original power plant building is to be enlarged to twice the size as
the original. The above photo from the 1917 Report to the
Governor shows work beginning for the addition. In addition a
larger outlet was needed to discharge the water used to turn the turbines. See the bottom photo of the building and large
outlet today. The original ports were small to handle the volume of water.
Just below is an old colorized post card from the time the spillway and hydroelectric station was being built. It shows the penstocks for the conveying of water to the power plant. Originally only three were needed as there were only three turbines. As you see there are three more to the left that were constructed for future use if the plant needed to be enlarged....which it did and they were put in service to operate the three new additional turbines installed .

The next old colorized post card below shows the interior of the enlarged power plant. Compare this with the interior photo from last week of the original plant. (photo courtesy of czimages contributor Bill Fall)
Once again, the photo at the very bottom is a modern day photo of the plant which hasn't changed physically since 1917.
This has been an interesting two weeks of study once I realized that the original plant had to be enlarged. All the years I drove over the Gatun Spillway bridge to visit the ski docks or go tarpon fishing on the apron of the spillway, I never paid much attention to the power plant nor even considered the significance of this plant in it's early days up till today.
