Sulphur dioxide is formed when coal containing sulphur is burned during power production. The coal we use in power production typically has lower quantities of sulphur.
Nitrogen oxides are formed when natural gas or coal are burned during power production. In sufficient quantities and with the correct environmental conditions, nitrogen oxides can lead to the formation of smog.
Both of these emissions can also add to the creation of acid rain when they mix with moisture in the air.
Emissions reduction activities
We are currently engaged in a sulphur dioxide testing project at the Shand Power Station. This project involves a series of mechanical improvements related to sulphur dioxide emissions. The outcome of this project is more effective sulphur dioxide emissions control. It is important to reduce sulphur dioxide emissions not only because of its environmental impact, but because lower sulphur dioxide emissions accommodate more effective carbon dioxide emissions controls.
To mitigate the emission of nitrogen oxides, we have implemented an ongoing nitrogen oxide program that attempts to reduce emissions by modifying coal combustion conditions.
