Experts warn nation's power grid growing more unreliable

Keep your flashlight and generator handy. Experts are warning of more stress on the power grid, which took a hit and went down in the Northeast blackout of 2003.

The group that oversees the grid says the system's reliability will only get worse over the next decade. That's because electricity demand is expected to grow faster than new power-generation capacity.

The North American Electric Reliability Council specifically warns the power-supply cushion will drop to unhealthy levels in the next two to three years in these areas: Texas, New England, the mid-Atlantic, the Midwest and the Rocky Mountain region.
