Assignment 2 – Group work
For this task, you will create a microgrid project connected to a power grid using HOMER Pro. You
will use the various features of the tool to perform a project analysis.
Please note:
• The use of HOMER Pro is mandatory. Instructions on how to install HOMER Pro can be found
on Moodle.
• You will collaborate with the same group as Assignment 1 for this task.
• Answer the open questions in each assignment section and use charts or screenshots from
HOMER Pro to support your answers.
• Your assignment answers should be presented in a written report. You may also include a
video to support your project if you believe it will be beneficial. The assessment will
recognize creativity.
• The deadline for submitting the report is April 9th.

Mandatory requirements:
1. For simplicity, you will model a “single load” microgrid. You can choose any type of customer
load (Commercial, industrial, etc.), but remember that this choice will greatly impact your
system’s performance.
2. Whatever type of load you select, scale it appropriately, using HOMER Pro’s built-in features,
to a minimum of approximately 150 kW peak requirement.
3. Your project needs to be connected to the distribution grid. You need to select at least two
DER units.
4. In the general project settings, choose a project life of 20 years, and a discount rate of 10%.

SECTION I – RESOURCES AND LOADS
1. Provide a summary of the climate and natural resources of your selected location. What
resources are significant in the area, and when are the peak months?
2. Explain the behavior of your electric load, including seasonal and daily patterns for both
weekdays and weekends.

SECTION II – TARIFFS’ DEFINITION
Use HOMER Pro’s Advanced Grid module to build a time-of-use – TOU (or “scheduled”) tariff rate
structure with seasonal and day-of-the-week rate variations. Try to use realistic electricity prices. If
you include net metering in your project, choose a sellback rate that is 0.5x the value of the electric
rate for each rate period. Describe the overall tariff you built.
