The energy industry is teeming with M&A activity, as companies seek to improve operations. Hubbell, Ingersoll Rand and private equity firms AE Industrial Partners and Genstar Capital are among the buyers.

Companies in the energy industry are focused on improving operational efficiencies and analytical capabilities. The issues are urgent for oil and gas companies, because depressed prices mean profits are hard to come by, says Caroline Blitzer Phillips, who advises clients on energy deals as a partner at law firm Vinson & Elkins. They are also essential for renewable energy, which “has been quite expensive in some cases, because the infrastructure is not in place.”

From providers of “smart grids” to developers of energy management software, here are 14 recently acquired targets.
