Ekibastuz GRES-2 Power Station

The GRES-2 Power Station (or Power Station Ekibastuz) is a coal-fueled power generating station in Ekibastuz, Kazakhstan. GRES-2, built in 1987, has installed capacity of 1,000 MWe and has the world's tallest flue gas stack at 419.7 metres (1,377 ft) high. The chimney is about 38 metres (125 ft) taller than the Inco Superstack in Sudbury, Canada. Locals refer to it as "the Cigarette Lighter". This chimney is the tallest chimney ever built.

The power station is the start of the Powerline Ekibastuz–Kokshetau and uses a transmission voltage of 1,150 kV, the highest transmission voltage in the world. The extension of this line to Elektrostal in Russia is also designed for 1,150 kV, but it currently operates at only 400 kV. About 3/4 of the energy produced by GRES-2 is exported to Russia.
