Pot producers add demand on Northwest power grid

SEATTLE (AP) — As more marijuana producers move their plants indoors over the next two decades, the grow operations in Washington state are expected to need as much electricity each year as what a small Northwest city consumes, according to an energy forecast by regional power planners.

Demands on the Northwest electrical grid would grow further if Oregon voters pass a ballot initiative in November to legalize recreational pot use, the Northwest Power and Conservation Council said.
