About 4 years ago I took my electrical power company up on an offer for them to install a whole house surge protector for an additional $5 per month. They provided a $10k insurance policy against any electrical damage to enter the home via the power lines.
Personally, I don't think they do anything but provide additional insurance but it can't hurt to have.
-IMO
