Water is a large component of the power generation process. Demineralized water is heated into steam that spins the turbines that create electricity. Cooling water is drawn into the plant to cool the steam.

What appears as “vapor” discharging from the plant is actually pure steam. This picture shows the various vents where steam is exhausted into the atmosphere. The only part of the plant that releases combustion emissions, or “smoke,” is the unit stack. We work in earnest to keep these emissions well below allowable limits.

Steam is released from vents on the rooftop.
