The TE business process is straightforward. There are tenders and transactions. There are two kinds: “forward” and “spot.”

Here’s an example of how TE works for a consumer.

My energy management system (EMS) automates this process for both energy and transport.
• Based on my typical usage, I automatically transact with one or more suppliers for delivery of a fixed quantity of energy in each hour of the year(s) for a fixed monthly payment (subscription.)
• If I use less than I subscribed for in each hour then I am paid for the difference at an hourly spot price.
• If I use more than I subscribed for then I pay for the difference at an hourly spot price.
• At any time I can automatically buy or sell a quantity of energy at current tendered prices.
