Specialised engineering Design initiated for a large-scale 300 MW windfarm project
- Power Projects has been engaged to carry out the complete Engineering Design and Sign-off for a 300 MW Windfarm located in Tamil Nadu.
• The scope involves a full Design of 33 kV network drawings, pooling substation documentation and unit substation design packages.
• This assignment strengthens Power Projects’ growing role in supporting large renewable energy projects with reliable and standards-based engineering expertise.
- Project Overview
Power Projects has been selected to deliver the engineering Design for a 300 MW windfarm project in Tamil Nadu. The engagement covers verification of all 33 kV transmission and distribution drawings, pooling substation design packages and unit substation documentation.
The objective is to ensure that every engineering document is accurate, compliant and ready for construction without rework. The Design will strengthen project reliability, reduce design-related risks and support a smooth transition to execution.
- Scope Highlights
Under this engagement, Power Projects will conduct a complete technical Design of the windfarm’s electrical design. The scope includes evaluating the 33 kV network, checking pooling substation layouts, designing unit substation drawings and validating all related engineering documents.
The Design also covers equipment alignment, interface checks, rating verification, safety considerations and compliance with regulatory standards.
This structured Design helps ensure that the windfarm’s electrical design is robust, reliable and suitable for large-scale renewable integration.
- Engineering Design and Compliance Validation Developed to Match Standards
Power Projects will validate all engineering documents against relevant IS/IEC standards, utility specifications and best engineering practices. Each drawing will be designed for technical accuracy, compliance requirements, protection boundaries, cable arrangements, equipment ratings and system integration behaviour.
The engineering validation ensures that the final document set is construction-ready and satisfies the requirements for project execution, material procurement and regulatory approval.
- Technical Scope and Methodology
Power Projects will adopt a structured approach to complete the engineering Design with clarity and precision.
4.1 Document Collection and Preliminary Assessment
All available specifications and references will be collected and Designed:
- Verification of document completeness
• Identification of version conflicts or missing data
• Categorisation of drawings based on system boundaries
• Early detection of design gaps or inconsistencies
This ensures a clear starting point for the technical Design.
4.2 Detailed Technical Design
Each drawing will be designed in detail, covering:
- 33 kV single line diagrams, layouts and protection boundaries
• Pooling substation arrangements, equipment interfaces and feeder routing
• Unit substation design logic, metering and CT/PT placement
• Cable sizing, routing, interconnection accuracy and earthing details
• Rating verification for transformers, breakers and auxiliary systems
The Design implies safety, coordination or constructability.
4.3 Standards and Compliance Validation
All documents will be created as per standard guidelines against:
- CEA Technical Standards
• IS/IEC codes
• Utility requirements for windfarm evacuation systems
• OEM-recommended engineering practices
This ensures the design is safe, compliant and suitable for grid integration.
4.4 Final Design
After completing the technical validation, Power Projects will deliver:
- Designed and final drawings
• A consolidated list of documents
• Inputs required for regulatory filings or utility submissions
This ensures the project is prepared for smooth implementation.
- Timeline
Despite the scale and complexity of a 300 MW network, the complete engineering Design will be delivered within a 8-week schedule upon receipt of the PO and full documentation.
- Supporting India’s Wind Energy Growth
India’s renewable energy sector continues to grow rapidly, increasing the need for high-quality engineering Design and system validation. Windfarm designs must meet grid integration requirements, safety standards and project timelines to avoid rework and construction delays.
Through structured engineering Designs like this, Power Projects helps developers and project teams:
- Improve design accuracy
• Reduce engineering-related delays
• Enhance safety and compliance readiness
• Strengthen grid-integration reliability
• Avoid costly rework during construction
• Support faster approvals and execution
• Improve system performance throughout operation
These Designs play a crucial role in enabling safe, reliable and efficient windfarm development across India.
