# EPANET: [ENERGY]

[ENERGY]

Purpose:

Defines parameters used to compute pumping energy and cost.

Formats:

GLOBAL PRICE / PATTERN / EFFIC value

PUMP pumpID PRICE / PATTERN / EFFIC value

DEMAND CHARGE value

Remarks:

1. First format is used to set global default values of energy price, price pattern, and pumping efficiency for all pumps.
2. Second format is used to override global defaults for specific pumps.
3. Parameters are defined as follows:
   - PRICE = average cost per kW-hour,
   - PATTERN = ID label of time pattern describing how energy price varies with time,
   - EFFIC = either a single percent efficiency for global setting or the ID label of an efficiency curve for a specific pump,
   - DEMAND CHARGE = added cost per maximum kW usage during the simulation period.
4. The default global pump efficiency is 75% and the default global energy price is 0.
5. All entries in this section are optional. Items offset by slashes (/) indicate allowable choices.

Example:

[ENERGY]
GLOBAL PRICE 0.05 ;Sets global energy price
GLOBAL PATTERN PAT1 ;and time-of-day pattern
PUMP 23 PRICE 0.10 ;Overrides price for Pump 23
PUMP 23 EFFIC E23 ;Assigns effic. curve to Pump 23
