Smart Energy Profile v1.0 Pricing Functions
• Current Price – Sets base price in the HAN device.
• Next Price – Allows base price to be changed with Start Time in the future.
• Price Event – Used to allow a temporary change in price (i.e.. Critical Peak Price). A Price Event supersedes all other prices while active and can cut across pricing tiers.
• Tiered Pricing – 5 pricing tiers supported, each with its own Current Price, Next Price and Price Event with start time and duration. Pricing tiers match the TOU Rate schedule and must be set up and programmed into the meters.

Key Points of Pricing
• Backhaul network traffic is minimal in scenario where prices will change infrequently.
• Price events minimize network management tasks and bandwidth usage by allowing a single communication to occur with meter to invoke temporary price changes…restore to current price is automatically accomplished.
• With TOU, price events can span multiple TOU periods with minimal backhaul traffic.
• Recurring daily changes in price can be set up as TOU schedule switch points thus better ensuring delivery of price information even with backhaul network abnormalities.
