DistributTECH, the premier conference for the utility sector, kicks off today in San Antonio, TX. GigaOM’s Katie Fehrenbacher is there and in terms of the smartgrid, it’s clear that software solutions and data analytics are hot. Tendril has completed its transition to a fully fledged software provider with its own API and has a new deal with BMW to help provide software to manage charging for the new electric beemer. And OPower has hit its 25 millionth home energy report, saving consumers a $100 million. As smartmeter penetration hums along, the opportunities for software layers that create energy savings remain exciting.
