To some people it will matter and some it won't.
I probably wouldn't want it personally, but you will see plenty of others buy there so obviously it doesn't matter to some.
High tension power lines will lower the price for a property anywhere... Most people prefer not to own a home with power lines directly behind the property (unless they get it to a great price)... There is conflicting information about the health effects these utilities pose on humans, however aethetically not very appealing...
Best of luck,
