Introduction
A 1000 kVA compact substation is a pre-fabricated, self-contained unit that integrates high voltage switchgear, a distribution transformer, and low voltage distribution equipment into one compact, weatherproof housing. These substations are ideal for urban, industrial, and infrastructure projects where space is limited.
In this article, PINEELE presents a comprehensive guide on the price of 1000 kVA compact substations, covering various configurations, influencing factors, typical market ranges, and cost-optimization strategies.
Average Price Range for 1000 kVA Compact Substation
The price of a 1000 kVA compact substation typically ranges from USD $18,000 to $45,000, depending on multiple factors such as:
- Transformer type (Oil-immersed vs Dry-type)
- Primary voltage level (11 kV, 13.8 kV, 33 kV)
- Protection type (fuses, VCB, RMU)
- Enclosure material (mild steel, stainless steel, galvanized, concrete)
- Custom features (smart metering, SCADA readiness, cooling system)
| Substation Type | Estimated Price (USD) |
|---|---|
| Basic Oil-type 11kV | $18,000 – $22,000 |
| With RMU (Ring Main Unit) | $22,000 – $27,000 |
| Dry-type Transformer | $25,000 – $32,000 |
| Smart Substation w/ Monitoring | $35,000 – $45,000 |
Technical Specifications of a 1000 kVA Compact Substation
| Parameter | Specification |
| Rated Capacity | 1000 kVA |
| Primary Voltage | 11 / 13.8 / 33 kV |
| Secondary Voltage | 400 / 230 V |
| Frequency | 50 or 60 Hz |
| Cooling Type | ONAN (Oil) or AN (Dry-type) |
| Vector Group | Dyn11 (Standard) |
| Short Circuit Impedance | 6.25% (Typical) |
| Protection Devices | HV Breaker / RMU, Relays, LV MCCBs |
| Standards Compliance | IEC 62271, IEC 60076, ANSI, GB |
Main Components Included
A compact substation typically includes:
High Voltage Section
- Load Break Switch (LBS) or Vacuum Circuit Breaker (VCB)
- Ring Main Unit (optional)
- Surge Arresters
Transformer Section
- 1000 kVA Oil-immersed or Dry-type transformer
- Cooling fins or forced ventilation
- Oil containment tank (if oil-filled)
Low Voltage Section
- MCCB / ACB incomers and feeders
- Energy metering, power factor correction (optional)
- Remote monitoring & SCADA (optional)
Factors Affecting the Price
1. Type of Transformer
- Oil-filled is more affordable
- Dry-type is more fire-resistant and compact
2. Switchgear Configuration
- VCB + Relay is costlier than basic fuse protection
- Ring Main Units (RMU) add significant cost but improve reliability
3. Enclosure Type
- Mild steel (basic)
- Galvanized or stainless steel (for corrosive environments)
- Concrete housing (for high-durability applications)
4. Smart Features & SCADA
- Remote monitoring, smart sensors, IoT modules add ~$2,000–$8,000
5. Customization & Standards
- Special protection schemes, utility-specific specs, explosion-proof design, etc.
Price Optimization Tips
- Choose standard voltage and vector group to avoid custom design charges
- Go for oil-type if space/fire safety regulations allow
- Minimize customization unless required
- Order in bulk for project-based pricing
- Work with experienced OEMs like PINEELE to get direct factory pricing
