Pricing Analysis
Average project pricing is rising gradually because of higher material costs, advanced control features, and increasing customization requirements for utility-specific grid conditions. Service-inclusive contracts command better pricing than equipment-only supply because they reduce commissioning and performance risk for buyers.
| Cost Component | Share (%) |
|---|---|
| High-voltage electrical components and insulation systems | 34% |
| Engineering design and systems integration | 22% |
| Manufacturing, assembly, and factory testing | 18% |
