Many thermal power plants are located along Osaka Bay and along the Inland Sea, areas subject to strict environmental regulations. In order to comply with these strict regulations, the power plants either use fuel that is low in sulfur and nitrogen, or are equipped with desulfurization and denitrification units. Those plants without desulfurization and denitrification units use high-quality fuel that is especially low in sulfur. Kansai Electric is working to maintain a stable, long-term procurement of high-quality fuel (with low content of sulfur and nitrogen), in consideration of the environment.

Fuel Procurement measures  [ LNG ] Because of its environment-friendly characteristic, we are aggressively promoting the utilization of LNG (approximately 60% of all fuel used for thermal power generation).  [ Petroleum ] About 70% of the petroleum that we use is ultra-low sulfur fuel oil with sulfur content of less than 0.1%.

Facilities measures We have been successfully decreasing sulfur oxides at power plant outlets, using a desulfurization system which can reduce the sulfur content of exhaust gas to around 0.1% even when we use fuel oil with a sulfur content of 0.6%-1%.
