Supply vs. Delivery Split
Many electricity bills include two main components: supply and delivery.
- Supply is the cost of the electricity you use (the energy itself). In deregulated markets, customers may be able to choose a supplier for the supply portion.
- Delivery is the cost to deliver electricity through the utility’s infrastructure (poles, wires, meters, maintenance, and outages). Delivery is handled by the local utility and generally remains the same even if a customer switches suppliers.
This “split” is why customers can often switch suppliers without changing their utility.
