Vermont Electric Power Company Vice President Kerrick Johnson says that cost was to buy replacement power while the line in the Northeast Kingdom town of Concord was shut down for repairs. Replacing the shot-out insulators cost about $250,000.
The transmission line is capable of carrying 10 percent of the electricity used throughout New England.
The damage was discovered last Friday and took two days to repair.
According to reports, 167 insulators were shot out. The case was reviewed by state and federal authorities to determine if it was terrorist-related, but it's being treated as vandalism.
