Bloomberg: Why Elon Musk’s Batteries Scare the Hell Out of the Electric Company:

Here’s why something as basic as a battery both thrills and terrifies the U.S. utility industry.

At a sagebrush-strewn industrial park outside of Reno, Nevada, bulldozers are clearing dirt for Tesla Motors Inc. (TSLA)’s battery factory, projected to be the world’s largest.

Tesla’s founder, Elon Musk, sees the $5 billion facility as a key step toward making electric cars more affordable, while ending reliance on oil and reducing greenhouse gas emissions. At first blush, the push toward more electric cars looks to be positive for utilities struggling with stagnant sales from energy conservation and slow economic growth.

Yet Musk’s so-called gigafactory may soon become an existential threat to the 100-year-old utility business model. The facility will also churn out stationary battery packs that can be paired with rooftop solar panels to store power. Already, a second company led by Musk, SolarCity Corp. (SCTY), is packaging solar panels and batteries to power California homes and companies including Wal-Mart Stores Inc.
While the headline is true, it’s unfortunate.
Shouldn’t we instead be thinking how amazing it could be if regular people could generate their own electricity, saving thousands of dollars a year?
