Peak Load

More about peak

It is important to educate our students, staff and faculty on peak in order to reduce costs and to encourage behavior changes necessary for the campus to maximize our role in reducing energy use as outlined in the Integrated Energy Master Plan.

Simple explanation of our energy bill

Back to top

Indiana University's electric bill is basically made up of two components.


Total electricity used- measured in kilowatt hours (kWh).  This defines how many kilowatts we used over the billing cycle.

AND

Demand Charge- measured in kilowatts (kW). This is the highest capacity the campus requires over a 30-minute period in each billing cycle.

Demand Charge is also referred to as Peak Demand, Peak Load and/or Peak Charge.

Cost impact of peak demand charge

Back to top

This Peak Demand Charge makes up 40-50% of our electric bill. This is why we focus on minimizing the power required by the university during the times we are most likely to hit peak.

Peak occurs on campus sometime between 12:00pm and 5:00pm.

Effectively managing that 30-minute period helps to drastically reduce electric costs.

On Peak Energy Charge- IU is $22/kW

Off Peak Energy Charge- IU is $.07/kWh

Think of it this way, if we lower the peak demand by 1,000kW we will save the university $22,000 each month! This is $264,000 each year.

Peak demand on average for Indiana University Bloomington:

Janurary-March:               27,970 kWh

April-May:                            35,148 kWh

June-August:                       39,347 kWh

September-December: 32,906 kWh
