Investing Topics: Warren Buffett

As a long-time shareholder of Berkshire as well as many utilities, I’m encouraged. I’m skeptical of some of the names being floated as MidAmerican’s next potential targets. But the feature article highlights several companies that fit the mold of NV Energy and PacifiCorp, which Berkshire bought in March 2006 from the former ScottishPower.

MidAmerican earned $1.47 billion in 2013 as one of Berkshire’s “Powerhouse Five” non-insurance businesses. That was approximately 7.5 percent of the company’s overall profit, a share that will rise to around 10 percent in 2014, thanks to a full year of owning NV Energy.

Even after the next acquisition, electric utility assets will be less significant to Berkshire’s fortunes than insurance, or even railroads (20 percent of profits). But there are two clear takeaways from Mr. Buffett’s continuing interest in the power sector.

First, MidAmerican is likely to buy another utility this year, handing investors windfall gains. Second, there are regulated electricity assets that still meet the criteria of the world’s most successful value investor.
