Tokyo this week saw its second major power crunch of the year, stretching the grid and forcing offices to turn off lights to conserve electricity. But the worst may be yet to come.

The situation in the nation’s capital so far hasn’t spiraled into a full-blown crisis thanks largely to ample supply in other regions, allowing utilities to send spare electricity. Still, there is a danger that scorching hot weather later this summer will envelop the entire country, heightening the risk of blackouts and renewing the government’s call to save electricity.
