Pacific Power, Portland General Electric Say Indoor Marijuana Grows Straining Oregon’s Electrical Grid

OREGON:  Indoor growing operations for legal marijuana businesses are causing problems for Oregon’s electrical grid, according to officials from a state electrical utility company.

Pacific Power said Wednesday that grow operations have taken grids above capacity, blowing out seven transformers since July and causing outages and equipment damage, the Statesman Journal reported.

The problems are a remnant of marijuana’s black market past, when substandard electrical work powered the lights at growing sites.

Portland General Electric has had similar problems, according to spokesman Steve Corson. He said anecdotal reports from PGE crews show about 10 percent of their transformer blowouts are from growing operations, with about 400 blowouts each year.
