        Electrical Power Supply Systems
This section covers how electrical energy is generated, transmitted, and distributed to various consumers.

                   Authorities for Power Supply 
- Government Regulatory Bodies: Agencies that oversee electrical infrastructure, enforce regulations, and ensure compliance with safety standards (e.g., Energy and Petroleum Regulatory Authority - EPRA in Kenya).
- Utility Companies: Organizations responsible for generating and distributing electricity (e.g., Kenya Power, Rural Electrification and Renewable Energy Corporation).
- Independent Power Producers (IPPs): Private entities that generate and supply power to the grid, often using renewable energy sources like solar, wind, and hydro.
- Renewable Energy Providers: Companies or initiatives focused on supplying green energy alternatives to reduce reliance on fossil fuels.

           Types of Power Supply Systems

1. AC (Alternating Current) Power Supply:
   - Standard form of power supply used in homes, industries, and businesses.
   - Allows easy voltage transformation and efficient transmission over long distances.

2. DC (Direct Current) Power Supply:
   - Used in battery-powered applications, electronics, and renewable energy systems.
   - Typically more stable but less suitable for long-distance transmission.

3. Grid-Tied Systems:
   - Connected to the national or regional electrical grid.
   - Provides a stable source of power but may be subject to blackouts.

4. Off-Grid Systems:
   - Independent from the main electrical grid, often powered by renewable sources.
   - Used in remote areas where traditional electricity access is limited
