Why did TEPCO delay the Kashiwazaki-Kariwa restart?

An alarm indicated a minor electrical discharge from the No.6 generator, prompting TEPCO to halt power generation and transmission to investigate. This likely pushes back the planned March 18 commercial start while teams confirm root cause and complete retests. Safety, reliability, and regulatory communication drive the revised timing.

How could the delay affect TEPCO stock in the short term?

Headline risk can weigh on sentiment and keep the shares range-bound. Without nuclear output, cost savings are delayed, so earnings visibility stays limited. Traders may lean on technical levels, while investors await a clean restart timeline to reassess margins and valuation for TEPCO stock.

What technical levels are most important right now?

Watch support around ¥596 and deeper near ¥580. Resistance sits near ¥667, then ¥718 to ¥738. RSI near 48 and a negative MACD show neutral to soft momentum. ATR around 34 suggests wide swings, so plan entries and stops with extra room for volatility.

Is TEPCO stock cheap on valuation?

Price-to-book is about 0.33x and price-to-sales near 0.16x, both low. That looks inexpensive, but earnings and cash flow are still weak, and leverage is high. A stable nuclear restart is needed to close the gap between apparent value and realized profitability.

What should investors monitor next?

Focus on TEPCO’s investigation results, any Nuclear Regulation Authority feedback, and an updated schedule for the No.6 unit. Also watch thermal fuel cost signals and summertime capacity plans, which shape margins. Clear, verified progress is the key catalyst for TEPCO stock strength.
