International energy giant TransCanada says it wants to sell its series of power dams on the Connecticut River. And at least one Vermont lawmaker thinks the state should consider purchasing the power generating hydro system.

The hydro system includes dams in Wilder, Bellows Falls and Vernon, Vt. The last time the dams changed hands the state of Vermont considered purchasing the renewable energy source.

The previous owner of the almost 500-megawatt hydro system was USGen New England, which filed for bankruptcy protection in 2003.

The state created the Vermont Hydroelectric Authority at the time to take a look at the dams, but in the end, Vermont was outbid by TransCanada.

Now TransCanada says it wants to sell its Connecticut River hydro assets. Rep. David Deen, D-Putney, says he’s going to talk to his fellow lawmakers about the pending sale.

“I think the state ought to buy them,” Deen says. “I mean this is the largest hydroelectric facility in New England. So, yeah, I think it’d be a good idea, but that’s me.”

Deen is chairman of the Fish, Wildlife and Water Resources Committee, and he’s also the Upper Valley River Steward for the Connecticut River Watershed Council.

The hydro system includes miles of protected wildlife resources, which the owner of the hydro system manages.

Deen says he was surprised at TransCanada’s announcement. And a state acquisition might be a long shot because Deen says there could be buyer already lined up.

“I have no idea what the timing on this sale is,” says Deen. “These things could sell tomorrow. I’m certainly going to talk to my fellow House members about it. And actually, we already have. Everybody remembers that we came close to buying these dams last time they were on the market.”

TransCanada announced just this month that it wanted to buy 15,000 miles of natural gas pipeline for about $10 billion, and the deal is being partly financed through the sales of its northeast power assets.

The company is also currently in the middle of relicensing the dams with the Federal Energy Regulatory Commission.

Deen says the relicensing will proceed despite of the pending sale.

EDITOR’S NOTE: Proposed sale of TransCanada’s hydroelectric plants along the Connecticut River in Vermont and the pending sale to Canada’s Public Sector Pension Investment Board of FirstLight’s Massachusetts hydroelectricity facilities along the river in Massachusetts — including the Turners Falls, Cabot Station and Northfield Mountain projects — comes as they are in the midst of relicensing by the Federal Energy Regulatory Commission.
