In the past two weeks, Portland General Electric has held several public meetings about its plans for a new high voltage power line.
Called Cascade Crossing, PGE wants to build a 200-mile, double circuit, 500-kilovolt power line from Boardman to Salem. Along the way, it crosses two national forests and the Warm Springs reservation. If all goes according to plan, construction will begin in late 2012 and the power line will be operating during the first half of 2015. . .
Do We Really Need This Power Line?
PGE warns that our current transmission system to close to capacity. Despite the growth in population and the increased demand for electricity over the past 25 years, no new major power lines have been built. Without this power line, PGE says our grid may become unreliable, raising the odds of power outages or brown outs. It also says this line will help bring in more renewable energy from the wind farms in Eastern Oregon. It says that will help Oregon meet state mandates to get 15% of our power from renewable energy by 2015. . .
As we’ve seen recently, PGE isn’t the only company proposing a new power line in the area. The Bonneville Power Administration is looking at a 70-mile high voltage line in SW Washington and a 28-mile line that runs through the Columbia Gorge Scenic Area. In Eastern Oregon, Idaho Power wants to build a 300-plus mile high voltage line from Boardman to SW Idaho.
How Do Projects Like These Affect The Forest and Wildlife?
. . . (Amy) Harwood (of the environmental group Bark) says energy corridors impact the forest in a number of ways. Creating a new path of clear cut makes it easier for invasive weeds to spread into the forest. Not only does it give them a foothold, but without tree cover the weeds thrive and become harder to control. . .
