Kansai Electric restarts Mihama No. 3 reactor after May turbine failure

The restart matters less as a power-market event than as a test of whether the turbine-casing defect that halted the unit in May has actually been resolved, given that a subsequent pipe leak interrupted the earlier adjustment runs. For Kansai Electric, the credibility of its maintenance and inspection regime is the real exposure, not the lost output. The open question is whether the current adjustment window passes without another forced halt before the planned commercial date.
