Portland General Electric (PGE) keeps many Birkenstock-shod feet warm: The company, formerly a subsidiary of Enron, generates, purchases, and distributes electricity to about 815,750 customers in Oregon. PGE's service territory covers 52 cities, including Portland and Salem. Its hydroelectric, coal-fired, and gas-fired plants had a generating capacity of more than 2,600 MW in 2009, and it purchased another 1,920 MW of generating capacity. PGE also markets wholesale electricity and natural gas to other utilities and marketers in the western US. In keeping with the "green" image of Portland residents, PGE leads the nation in residential customers who purchase power from renewable sources.
