Incident Report: Power and Network Outages at Zvandiri HOUSE


Zvandiri has been experiencing significant power and network outages due to a fault in the ZESA (Zimbabwe Electricity Supply Authority) power supply. The facility relies on a hybrid power system that includes both solar power and ZESA. The solar batteries are typically charged by sunlight during the day and supplemented by ZESA when necessary.


Over the past two weeks, a persistent fault in the ZESA supply has led to the solar batteries not being fully charged. This has resulted in frequent power outages affecting the entire facility. Additionally, the server located at House 11, which is solely dependent on ZESA for charging its batteries, has been directly impacted by the ZESA fault, causing network outages and disrupting communication and data services.

Temporary Measures:

In response to the crisis, a temporary measure was implemented by connecting the server to the main solar power system that supplies electricity to the entire house. While this solution restored network connectivity, it also increased the load on the solar power system, leading to power outages throughout the day due to the additional energy demand.


The power and network outages have had a detrimental effect on Zvandiri’s operations, causing disruptions in daily activities and potentially impacting the quality of services provided.


  • Immediate repair of the ZESA fault to restore the hybrid power system’s functionality.
  • Installation of UPS units: To mitigate the impact of power outages on critical systems, it is recommended to install Uninterruptible Power Supply (UPS) units for essential equipment, especially the server at House 11 and 12. UPS systems will provide temporary power during outages, allowing for a graceful shutdown of equipment or continuation of operations until the main power supply is restored.
  • Evaluation of the solar power capacity to determine if it can handle additional loads in emergency situations.
  • Installation of additional solar panels or battery storage to increase redundancy and resilience against future power supply issues.
  • Regular maintenance checks on both the solar and ZESA systems to prevent similar incidents.
