When Czechs want to power up, they turn to state-controlled EZ, (the lead company of CEZ Group) which produces, distributes, and sells electricity and heat to 3.5 million customers in the Czech Republic. EZ, formed by the government in 1992, is now publicly traded, although in 2008 the government continued to control 63% of its stock. Subsidiaries and affiliates of EZ form what is known as the CEZ Group, which has operations in coal mining and power generation and marketing across Central and Southeastern Europe. The CEZ Group serves 7 million customers and has about 12,200 MW of generating capacity.
