The GRES-2 Power Station (or Power Station Ekibastuz) is a coal-fueled power generating station in Ekibastuz, Kazakhstan. It is located close to Solnechny, by lake Shandaksor. The ashes of the station are dumped into nearby lake Karasor.^[1]

Description

GRES-2, commissioned in 1987, has an installed capacity of 1,000 MWe and has the world's tallest flue-gas stack at 419.7 metres (1,377 ft) tall. The reinforced concrete chimney is about 40 m (130 ft) taller than the Inco Superstack in Sudbury, Ontario, Canada. It is the tallest chimney ever built.^{[citation needed]}

The power station is the start of the Powerline Ekibastuz–Kokshetau and uses a transmission voltage of 1,150 kVAC, the highest transmission voltage in the world. The extension of this line to Chelyabinsk in Russia is also designed for 1,150 kV, but it currently operates at only 500 kV. About 3/4 of the energy produced by GRES-2 was^[when?] exported to Russia.

Fifty percent of GRES-2 shares are owned by Inter RAO UES, and fifty percent by Kazakhstan's government.^{[citation needed]}
