The slow but steady march to rebuild the World Trade Center in New York has reached another milestone.
Workers switched on a massive power system at the site Tuesday. It eventually will provide electricity to the center's signature skyscraper, a transit hub and the 9/11 memorial and museum.
The Port Authority of New York and New Jersey says the system of electrical feeders will supply 100 megawatts to the site.
That's enough juice to power 64,000 typical New York City apartments.
The unfinished One World Trade Center is now one of the city's tallest structures.
If construction continues at its current pace, it will pass the Empire State Building sometime this spring.
