Project Overview
Client & End User
Client: Three Star Engineering
End User: Angata Sugar, Kenya
Plant Capacity
Sugar Crushing: 2000 TCD
Boiler: 60 TPH
Steam Turbine Generator: 5 MW
Client Requirements & Project Initiation
At the project initiation stage, the client was actively searching for a competent and reliable EPC partner with proven expertise in industrial electrical system design for sugar plants and captive power generation. The key requirement was not limited to equipment supply alone, but extended to the generation of technically sound specifications, accurate load assessment, and engineering-driven design that balances reliability, operational efficiency, and cost optimization.
Technical Excellence
Translating process requirements into practical and dependable electrical designs
Operational Reliability
Ensuring continuous plant operation with minimal downtime
Cost Optimization
Optimizing CAPEX and OPEX through correct equipment sizing and VFD-based energy-
efficient solutions
Future-Ready Systems
Delivering future-ready and maintainable electrical systems
Based on these requirements, a holistic and engineering-led approach was adopted to design the complete electrical system, positioning the project as a benchmark for safe, efficient, and economical electrical design in the sugar industry.
Scope of Work & Design Philosophy
Complete Electrical System Design
Complete electrical system design covering load list preparation, HT & LT system design, transformers, PCC, MCC, VFD panels, motors, cable scheduling, earthing, and documentation.
Design Philosophy & Standards
The design focused on reliability, energy efficiency, safety, and future expandability, complying with IEC, IEEE, and relevant IS standards.
Load List Development & Power Generation
Load List Development
A comprehensive load list was prepared covering milling, boiler auxiliaries, turbine auxiliaries, utilities, and balance of plant, considering diversity, demand, and starting currents.
Power Generation & HT System
The plant includes a 5 MW steam turbine generator at 11 kV. HT panels with VCBs and numerical protection relays were designed for generator and transformer feeders.
Transformer & Distribution System Design
Transformer Design
11 kV / 415 V transformers were selected based on connected load, fault levels, voltage
drop, and redundancy requirements.
LT Distribution–PCC Design
PCC panels were designed with ACB incomers, fault-rated busbars, and outgoing feeders
to MCCs and VFDs.
MCC Design
Multiple MCCs were designed with DOL, Star-Delta, and VFD feeders. Type-2 coordination
and draw-out feeders were used for critical loads.
Motor Selection & VFD System
Cable Scheduling & Protection Systems
Cable Scheduling
HT and LT cables were sized considering current, voltage drop, short circuit withstand, and derating factors.
Earthing & Lightning Protection
A complete earthing grid and lightning protection system were designed as per IEC and IEEE standards.
Engineering Deliverables
Load List - Comprehensive equipment load analysis
SLDs - Single line diagrams
PCC & MCC Drawings - Detailed panel layouts
VFD Schematics - Drive system documentation
Cable Schedules - Complete cable routing plans
Earthing Layouts - Grounding system design
Technical Specifications - Equipment specifications
Conclusion
A Benchmark in Industrial Electrical Design
The project delivered a reliable, efficient, and scalable electrical infrastructure for a 2000 TCD sugar plant with 5 MW co-generation.
This comprehensive electrical system design demonstrates the successful integration of technical excellence, operational reliability, and cost optimization, establishing a new standard for sugar industry electrical infrastructure in East Africa.
