Compact Substation Price List

はじめに

In the modern energy landscape, コンパクト変電所 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.

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)

🇮🇳 India

• 250 kVA unit: ₹6.5 – ₹9 lakhs
• BIS & State Utility (e.g., TNEB, MSEDCL) approval may affect costs

🇿🇦 South Africa

• Eskom-compatible 500 kVA substation: ZAR 180,000 – ZAR 260,000
• Prices higher in coastal areas due to corrosion-resistant enclosures

🇲🇾 Malaysia (TNB Standard)

• 11kV/0.415kV kiosk substation (TNB-approved): RM 45,000 – RM 85,000
• Includes stainless steel option, smart energy meter

🇸🇦 Saudi Arabia

• 1000 kVA unit (33/0.4kV): $19,000 – $27,000
• Must follow SEC standards, SASO compliance

Optional Add-ons That Impact Price

• SCADA/IoT Monitoring System
• Fire Suppression System
• Surge Arresters, Ground Fault Protection
• Solar PV compatibility (Dual LV panel)
• Skid-mountable or pad-mountable base options

These can add 10%–40% to the base cost depending on specifications.

What’s Included in the Price?

Typically, a compact substation price includes:

• 3-compartment enclosure (MV + Transformer + LV)
• Transformer (as per spec)
• MV switchgear
• LV panel with protection
• Internal wiring & terminations
• Factory testing and type test certificate

Not included (usually):

• Civil foundation
• On-site installation
• Long-distance freight
• Utility-side approvals

Cost Saving Tips

• Stick to standard configurations when possible
• Avoid unnecessary add-ons (e.g., dual metering if not needed)
• 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.
