Berkshire Hathaway unit MidAmerican Energy is outdoing its boss, Warren warren buffett photoBuffett, in his home turf: deal making.

Mostly, MidAmerican has been known as the energy company where former Buffett lieutenant David Sokol made his mark. That was before Sokol resigned from Berkshire Hathaway last year amid questions about his stock purchases in a company Berkshire later acquired.

But in recent months, Iowa-based MidAmerican Energy has been snapping up a string of companies that even out-deals Buffett, who last year proclaimed himself on the hunt for acquisitions with an itchy trigger finger on his “elephant gun.”

Today, MidAmerican Energy agreed to buy a wind-turbine energy project under construction in Illinois.
