Erinjiyan Mini-Grid - Python Load Analysis & HOMER Pro Optimization

Integrated mini-grid demand and techno-economic study combining Odyssey customer-demand modelling, Python-based validation of an 8,760-hour annual load profile, and HOMER Pro hybrid-system simulation. The assessment covered 1,772 customer connections and evaluated PV, battery storage, diesel generation and grid support for a community demand of approximately 8.10 MWh/day.

Model assumptions & limits
  • Each point averages the same hour over all 365 days of the modelled 8,760-hour profile. Input load values are already in kW.
  • The CSV uses a 2017 reference calendar. It is a modelled demand profile, not a record of measurements taken in 2017.
  • An average day smooths seasonal and day-to-day peaks. The annual peak shown above is from the complete profile, not the average-day curve.
  • Business demand combines commercial and productive uses. Services combine anchor and public loads. Only group totals are published; customer identifiers stay private.

Model assumptions & limits
  • Annual source production totals 3,540.127 MWh. The report records 526.866 MWh of excess electricity.
  • Production share is a share of generated and purchased energy, not the renewable fraction of energy served. Storage and conversion losses separate production from consumption.
  • Served energy is the report’s AC primary-load consumption.
  • These are annual HOMER results for the selected configuration, not measured operating performance or an hourly dispatch forecast.
