A transmission utility continues to resist efforts to install an underground version of a new high-voltage power line, along Madison's Beltline. Aesthetic concerns have some opposed to above ground lines.
American Transmission Company Spokeswoman Sarah Justus says the cost of going underground is prohibitive. They estimate an underground line along the Beltline would increase the cost of the project by up to $300 million.
The state Public Service Commission is holding hearings on the power lines this week, with a decision expected in June. Justus says the PSC will have to consider whether it's justifiable to make customers pay extra for underground lines.
ATC has proposed two routes, along the Beltline, and across mostly farming areas in southern and western Dane County.
