We do, every year. Over half of our 5,000 mile system is already underground, and last year, we added another 71.42 miles of underground lines and eliminated 10.63 miles of overhead lines.

However, replacing the entire overhead system with an underground system isn’t practical – it’s not just the cost (which would be in the hundreds of millions of dollars and would significantly raise electricity rates), it’s also that outages on underground lines can be much harder to find and much more challenging to repair. Finally, there are many places in our area where it is impossible to put lines underground, due to geologic considerations, among others.
