Excellent summary!
GE acquired Remote Energy Monitoring (REM) in January – http://www.remuk.co.uk/geacquisition.php
Johnson Controls and EnergyConnect…not sure if I missed this in the list.
Thanks guys. Sorry if your comment was delayed, I just noticed them caught in the spam filter. I’ll add in these ones now.
You might add Schneider Electric and Alstom’s joint acquisition of Areva’s Transmission & Distribution business? It’s not as heavy on the “Smart” as it is on the “grid,” but at ~$6 Billion, it’s certainly hard to ignore. Both Alstom and Schneider Electric seem to banking on the grid in general for future growth.
Good list but missed a few:
EnerNOC bought M2M Communications, demand response provider with a lot of activity in irrigation pumps in CA
Johnson Controls acquired EnergyConnect Group, a demand response provider similar to EnerNOC but much smaller
ABB purchased Obvient Strategies to enhance the Ventyx software suite for organizations with geographically dispersed assets
GE bought Lineage Power Holdings for data center efficiency and Remote Energy Monitoring which makes AMI hardware and software for the UK market
Thanks guys. I added these all in.
