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.

01 / Engineering Scope

Technical work and responsibilities.

  1. 01

    Reviewed and processed the Odyssey-derived annual community load profile covering 8,760 hourly records.

  2. 02

    Validated the annual dataset in Python for completeness, timestamps, missing values and system-demand consistency.

  3. 03

    Calculated system demand indicators including peak load, minimum load, average demand, annual energy consumption and load factor.

  4. 04

    Developed annual load-profile, average 24-hour demand and load-duration-curve visualizations.

  5. 05

    Configured and evaluated a hybrid PV, battery energy storage, diesel generator and grid-support architecture in HOMER Pro.

  6. 06

    Assessed energy production, storage operation, generator contribution, renewable penetration and system economics.

  7. 07

    Compared technical and financial simulation cases to support selection of a technically viable hybrid configuration.

02 / Delivery Outcomes

Measured project results.

  1. 01

    Validated all 8,760 hourly demand records with no missing or invalid system-load values.

  2. 02

    Calculated a peak community demand of 545.43 kW, average demand of 337.45 kW and minimum demand of 171.62 kW.

  3. 03

    Calculated average daily energy consumption of 8,098.90 kWh/day and annual demand of approximately 2.956 GWh.

  4. 04

    Confirmed a community load factor of 61.87%, indicating sustained utilization across the daily demand cycle.

  5. 05

    Evaluated a HOMER engineering case comprising approximately 2.2 MW of PV, 5.0 MWh of battery storage, a 610 kW diesel generator and a 606 kW converter.

  6. 06

    The selected engineering simulation produced a total net present cost of approximately $3.14 million and a levelized cost of energy of $0.111/kWh under the modelled assumptions.
