7: Time of Use Function
7.1: Introduction
A Time of Use (TOU) usage structure takes into account the quantity of energy used
and the time at which it was consumed. The Nexus® 1262/1272 meter’s TOU
function, available with the CommunicatorPQA® software, is designed to accommo-
date a variety of programmable rate structures. The TOU function accumulates data
based on the time-scheme programmed into the Nexus® meter.
See the CommunicatorPQA®, MeterManagerPQA ® , and EnergyPQA.com ® Software
User Manual for details on programming the Nexus® 1262/1272 meter’s TOU calen-
dar and retrieving TOU data.
7.2: The Nexus® Meter’s TOU Calendar
A Nexus® meter’s TOU calendar sets the parameters for TOU data accumulation. You
may store up to twenty calendars in the Nexus® Meter and an unlimited amount of
calendar files on your computer.
The TOU calendar profile allows you to assign a programmable usage schedule—eg,
“Weekday,” “Weekend,” “Holiday”—to each day of the calendar year. You may create
up to 16 different TOU schedules.
Each TOU schedule divides the 24 hour day into fifteen-minute intervals from
00:00:00 to 23:59:59. You may apply one of eight different programmable registers—
e.g., “Peak,” “Off Peak,” “Shoulder Peak”— to each fifteen-minute interval.
The Nexus® meter stores:
• Accumulations on a seasonal basis, up to four seasons per year
• Accumulations on a monthly basis
Seasonal and monthly accumulations may span one year into the next. Each season
and month is defined by a programmable start/billing date, which is also the end-date
of the prior season or month.
A season ends at midnight of the day before the start of the next season.
A month ends at midnight of the month’s billing day.
