"Unit 2: 15.0 MW (1929), Unit 3: 28.7 MW (1952), Unit 4: 37.5 MW (1959)" Unit 2 was retired in 2010 and Units 3 & 4 were converted to natural gas in 2017. [gem] So they paid for a fuel conversion just a year before they tore it down.
I was surprised by how small the generating units are in this station. But this plant has won awards for efficiency. [PowerMag]

Obviously, this plant could receive coal from barges. In fact, it appears that it could receive it only from barges. I don't see any rail service.

| Dennis DeBruler commented on Greg's post Unit 2: 15.0 MW (1929), Unit 3: 28.7 MW (1952), Unit 4: 37.5 MW (1959) So the satellite image must be at least four years old. |

The metal addons are electrostatic precipitators that were installed in the 1970s.

The small capacity of the plant explains why its storage pile is rather small.

| PowerMag "Boiler 1 is a Riley-manufactured, 850-psi pulverized coal (PC) boiler installed in 1959. Unit 5 is also a PC unit supplied by Riley in 1951, but it operates at 600 psi. Boiler 6 is the oldest and smallest of the three operating boilers and also operates at 600 psi. Boiler 6 was supplied by Combustion Engineering in 1941. None of the boilers has an economizer or reheat section, but they all have electrostatic precipitators that were added in the 1970s." The stockpile holds a 100-day supply for the winter months. If they get low and the river is still frozen, they have to truck coal from a rail delivery point about 10 miles away. They converted the boilers to burn PRB coal in 2000. I wonder where that coal is loaded onto barges. |
