EON has commenced full commercial operations at its 1,275MW gas-fired power plant on the Isle of Grain in UK.
The operations, at the plant estimated to built with an investment $816m, were delayed by seven months due to some technical problems.
With the start of the third and the final unit the company's Grain combined heat and power (CHP) station in Kent is now commercially available, reports Reuters.
The company also plans to open a CHP in the plant by the end of this year.
The CHP will export excess heat to national grid's nearby liquefied natural gas terminal.
