At 12:30 pm local time on Monday, the power went out. Engineers plan for failures in grids or surges in consumer demand that could destabilize the power supply. While the grid is powering back up, emergency services will likely be prioritized over things like stable internet connection, they say. They are going to be doing what is called a “black start"—a process that gradually reconnects power stations to form a functioning grid again. Electrical supply and demand has to be balanced to avoid further blackouts, meaning as power stations come online, only portions of the grid can come online with them, with the country gradually powering up, step by step.
