Tokyo Electric Power Co. and three other utilities are contemplating boosting non-nuclear thermal power generation by either building new facilities or expanding existing plants.
Tepco is planning a major increase in capacity by building facilities to generate around 6 million kilowatts, equivalent to nearly 10 percent of its current output of 65 million kw, a source familiar with the plan said Tuesday.
The expansion is equal to the capacity of six typical nuclear reactors. Tepco is expected to announce details Thursday for a tender to select builders for the new facilities in fiscal 2014, the source said.
