Introduction
In the modern energy landscape, compact substations have emerged as the go-to solution for medium voltage to low voltage transformation—especially in urban, industrial, and renewable power environments. Whether you’re planning a solar power station, a commercial complex, or an industrial expansion, understanding the compact substation price list is critical for budgeting and procurement.
This guide provides a transparent look into pricing by capacity, component, and region—equipping engineers, contractors, and procurement teams with accurate insights for 2024 and beyond.
What Is a Compact Substation?
A compact substation (also known as a package substation or kiosk substation) integrates the following three major components in a single, prefabricated unit:
- Medium Voltage (MV) Switchgear
- Power Transformer
- Low Voltage (LV) Distribution Panel
These units are fully enclosed, factory-tested, and designed for plug-and-play deployment. They are especially useful in space-constrained environments and applications requiring fast installation with minimal civil works.
Compact Substation Price List by Capacity
Here is a price estimate for standard compact substations based on rated transformer capacity. Please note that actual costs may vary depending on customization, country of origin, and included features.
| Rated Capacity | Voltage Rating | Estimated Price (USD) | Configuration Notes |
|---|---|---|---|
| 100 kVA | 11kV / 0.4kV | $5,000 – $6,500 | Oil-type, RMU, MCCB, basic enclosure |
| 250 kVA | 11kV / 0.4kV | $6,800 – $8,500 | IP54 steel box, MCCB, analog metering |
| 500 kVA | 11kV / 0.4kV | $9,000 – $13,500 | With RMU + SCADA-ready panel (optional) |
| 630 kVA | 11/22/33kV / 0.4kV | $11,500 – $15,000 | Optional stainless steel, surge arresters |
| 1000 kVA | 11/33kV / 0.4kV | $14,000 – $21,000 | ACB, digital metering, better insulation |
| 1600 kVA | 33kV / 0.4kV | $22,000 – $30,000 | Premium panel, forced cooling, IP55 enclosure |
Factors That Influence Compact Substation Prices
1. Transformer Type
- Oil-immersed: More cost-effective, suitable for outdoor
- Dry-type (cast resin): Fire-safe, indoor-friendly, more expensive
2. Voltage Level
Substations rated for 33kV cost more due to insulation, clearance, and switchgear complexity compared to 11kV units.
3. Switchgear Type
- LBS (Load Break Switch) – basic, economical
- RMU (Ring Main Unit) – more compact and robust
- VCB (Vacuum Circuit Breaker) – advanced, suitable for high-demand use
4. LV Panel & Metering
Adding ACBs, smart metering, and SCADA systems can increase price by 10–30%.
5. Enclosure Quality
- Mild steel with epoxy paint (standard)
- Hot-dip galvanized steel
- Stainless steel for coastal/chemical areas (adds 20–35%)
Regional Compact Substation Price Examples (2024)

- Order in bulk for discounts
- Consider local manufacturers for lower transport cost
- Ask for ex-works vs delivered pricing
FAQs: Compact Substation Price
Q1: Why do dry-type substations cost more?
Dry-type units use resin-encapsulated windings, ideal for fire zones and indoor use, but more costly in production.
Q2: Can I get a price for a solar-compatible unit?
Yes, most manufacturers offer hybrid-ready designs with dual LV outputs for grid + inverter.
Q3: How accurate are these price ranges?
They reflect average 2024 market values, but real quotes depend on brand, spec, and delivery location.
