Project Scope

Key Assumptions & Standards

The electrical works for the Suswa Solar Park Project cover all activities necessary for the design, supply, installation, testing and commissioning of electrical systems required to generate, transmit and integrate 120MW of solar energy into the national grid. These are designed and executed based on several key assumptions in compliance with internationally recognized standards to ensure quality, efficiency and safety.

1. Project Capacity and Phasing
Phase 1

Focused on delivering the initial 70MW with associated electrical infrastructure.

Phase 2

Completion of the remaining 50MW including grid connection enhancements.

All electrical designs, material procurement and installations will align with these phased implementation timelines.

2. Technology Selection
  • Monocrystalline Solar Panels are assumed for their high efficiency and reliability in Kenyan climatic conditions.
  • String Inverters are selected for scalability and ease of maintenance.
3. Grid Integration

~ The 10km loop-in, loop-out transmission line to the nearest substation will operate at medium voltage (33kV).

~ Synchronization with Kenya’s national grid will adhere to the Kenya Power and Lighting Company (KPLC) interconnection requirements.

DC to AC converters and step-up transformers are used for grid compatibility.

4. Site-Specific Conditions

~ The site in Suswa, Kajiado County, has high solar irradiance averaging 5-6 peak sun hours/day, making it suitable for a utility-scale PV plant.

~ Soil conditions allow for trenching and grounding systems without significant geological challenges.

5. Environmental and Safety Considerations
  • Compliance with national and international standards (IEC, IEEE).
  • Provisions for earthing and bonding to ensure safety and reliability.
  • The project assumes minimal disruption to the local ecosystem and complies with Environmental and Social Impact Assessment (ESIA) findings.
  • Adequate safety measures including grounding and surge protection are integrated into all electrical designs.

Purpose of Assumptions & Standards

  1. Consistency: Ensures uniformity across all project phases.
  2. Safety: Guarantees protection for personnel, equipment, and the environment.
  3. Reliability: Provides a robust and long-lasting electrical system.
  4. Compliance: Adheres to local and international codes for smooth project approval and grid integration.
