DF Exchange is a tool that complements the ongoing DF concept. 

The difference is about the integration time. While the traditional DF is associated with "calls" for the short term, the DF exchange is centered on contractual demands.

The concept is very simple. DF exchange is a tool to help energy users who pay for contracted demand to better adjust their contracted demands.

This has become important because these energy suers are facing a number of changes: 1) Their intensity of activities, 2) their energy conversion processes are changing, 3) what they are doing in each location is changing , 4) energy sources they are using may be changing with distributed generation and the list goes on and on!

But... the contractual arrangement for demand is a very stiff one and it makes sense since the electric power sector is a capital intensive one! Whether a fixed contract or a ratchet.

This concept DF exchange enables energy users better adjust their needs BUT making sure the local utility company also gains.

Watch this 4 minute video to get acquainted with this new proposition!

Rafael, I listened to this.  Isn't your industrial-commercial deal, where they were right next to each other, unusual?  It would seem to the uninitiated that most of these sort of exchanges would take place not in the same service area, but across boundaries, so transmission would be highly involved.  If this is wrong, you might explain it, so as to address a concern investors may have.

Julian, it might be conceived both ways (in the same service territory or not). The main aspect is always the same: increasing the load factor of the whole power supply chain. And, as we all know, the higher the overall load factor, the lower the Capital Expenditure cost related to kWh sales.
