Top 10 Smart Grid Companies

The top companies contributing to smart grid development and uptake have been ranked by revenue, and include Siemens AG, IBM and Cisco

The defining element of a smart grid system is the two way flow of electricity and data, in comparison to the one way flow of the grid. 

The developments in smart grid systems, including smart appliances, smart meters, smart substations and synchro phasors, has brought many critical improvements in the realm of energy production. Customers can see direct benefits through automated billing data collection, energy use tracking and cheaper rate alerts which directly save them money, and battery collections heading back to the main grid from consumers excess has wider benefits. 

According to Emergen Research, the global smart grid market is expected to reach US$122.97bn by 2027, having been valued at US$29.8bn in 2019. We’ve pulled together a list of the top smart grid companies, ranked by annual revenue.
