Smart grid software is in the news today. The big news is that ElectraLink has picked eMeter to help the electrical data brokering service communicate with UK’s smart meters as their numbers balloon in the coming years. A quick glance at eMeter’s technology, and it’s easy to see why. A little under the radar, unless you’re a business process management enthusiast, is IBM’s WebSphere Sensor Events software that’s meant to drive efficiency by making businesses responsive to sensor data and alerts. Think a little bigger and it becomes a telling clue to Big Blue’s approach to smart grid automation, not to mention a sign of fertile software development fields ahead.
