Construction Images

The images below document the construction of Navajo Generating Station from 1970-1976. Unit one came on-line in 1974, unit two in 1975, and unit three in 1976. The last unit (unit two) came off-line for the final time on November 18, 2019 at 12:09 PM. The photos on this page record different stages of the construction of Navajo Generating Station.

Breaking Ground for NGS

This is probably the earliest photo in my collection. Not much looks familiar in this picture because so much of it is at ground level and below. But Tower Butte is visible on the horizon on the far right side of the picture, so all is well. Click to enlarge.

Unit One From South

This photo is a look at the Unit One boiler structure from the south, looking north. The coal silos are clearly visible and the foundation columns are in place for the power block turbine deck. Click the image to enlarge. It looks like the Unit One Deaerator Storage Tank might be set in place.

Unit One Boiler Structure

This photo is from about the same time as the one above – probably a little bit earlier. It was taken from near where the dewatering bins will soon stand. The U1 coal silos are in place. If the deaerator storage tank is in the picture above, it’s not in this one. Click to enlarge.

Unit One From South

This photo was taken a little later than the ones above. Notice the first air ducts that are installed. The U1 and U2 elevator shaft is under construction. No sign yet of the construction elevator. The silos are visible as well as the deaerator and the deaerator storage tank are installed. Click the photo to enlarge.

Unit One Aerial

There’s a lot to see in this photo. Work is progressing on the turbine deck, including U2 and U3. the empty Service Water pond is there and the U2 cooling tower area is cleared off. The large rectangle building on the right was the Bechtel admin building. The smaller building next to it was the receiving dock. I used to make deliveries there when I worked for Wyckoff Trucking in the early 70s. The 2 long buildings where the U3 cooling towers would eventually be, were the barracks. The building at the end of the barracks was the cafeteria. The building next to the barracks was the Burtco Security admin building. Burtco provided the security for NGS in the early years.

Unit One Silos

Here’s a good closeup shot of the U1 coal silos at the 52′ elevation, looking south toward unit two. You can see the U1/U2 elevator shaft under construction to the left. The U1 deaerator and deaerator storage tank are to the right. How many workers do you see in this photo? Click to enlarge.

NGS Coal Yard Construction

This photo was taken from somewhere on the U1 boiler structure. The dewatering bins and the U1 fly ash bin are under construction. The train’s in the background. Click to enlarge. There’s a lot of detail to see in this one.

Open Turbine Deck

Here’s a never-to-be-repeated see-thru look at the NGS turbine deck and power block. Check out the step-side pickup truck on the far right. Those trucks with Bechtel stickers on the door were a common site around Page during that time.

Unit One in Color

This early snapshot gives us a look at the U1 boiler structure and the U1 & 2 power block foundation in living color. Click to enlarge.

Lake Pump Station

Preliminary work at the Lake Pump Station is underway in this photo. This small drill was used in advance of the one pictured below. The Lake Pump Station was always nice in the hot summer months because it was always freezing inside.

Lake Pump Station Drilling Rig

In this photo, drilling was well underway at the NGS Lake Pump Station to access the water from Lake Powell that was necessary for the operation of the plant. The first 3 pump shafts have been drilled and the crew is working on the fourth in this picture. The Lake Pump Station was next to the road to Antelope Point at Lake Powell. Click to enlarge.

Lake Pump Drill Bit

This is one of the drill bits used to drill the pump shafts at the NGS Lake Pump Station. Click image to enlarge.

Lake Pump Station Water Lines

Water from Lake Powell was delivered to Navajo Generating Station from the Lake Pump Station via these buried lines. There were 2 of these buried lines that ran side by side. The next photo shows that.

Lake Pump Lines

NGS Coal Yard From Unit One Stack

Somebody snapped this great photo from the top of the Unit one stack. I don’t know how high the stack was at this point but it was still being raised. A small corner of the coal hopper where the BM&LP train would soon be dumping its coal is on the far left of this picture. None of the above ground conveyor belts are covered at this point.

Construction on the Turbine Deck

1st Point Heater build?

IP Turbine Work

This may have been taken during an overhaul instead of NGS construction. I recognize an SRP face in it. But it’s a good picture so I’m including it.

50kV Catenary Work

The BM&LP (Black Mesa & Lake Powell) railroad was electric and powered by 50kV catenary sourced out of the NGS switchyard. This train brought coal to NGS 24/7 from the plant’s inception until its closure in 2019. Click image to enlarge.

BM&LP Engine House

Under construction and covered in clear plastic. Click to enlarge.

BC-2 Exposed

Here’s a look at BC-2 that took coal from the train hopper to above ground on its way to the plant silos. I walked this belt more times than I care to remember when I started my career with SRP.

BC-2 Covered

Is this going to be dug up and removed or just buried and forgotten?

Unit 3 Construction

Construction of unit 3 nears completion. Taken from the highway or the Lake Pump road. Click to enlarge.

There’s a lot of detail in this picture. Click to enlarge. You’ll be glad you did.

NGS Unit One Precipitator Construction

Here’s a great photo of the Unit One Precips under construction and a good look at the Unit Boiler construction. The precipitators came down a lot quicker than they went up.
