Compact Substation Price List

Introduction

In the modern energy landscape,محطات فرعية مدمجةhave 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 thecompact substation price listis 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?

Acompact 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.نوع المحول

Oil-immersed: More cost-effective, suitable for outdoor
Dry-type (cast resin): Fire-safe, indoor-friendly, more expensive

2.Voltage Level

Substations rated for33kVcost more due to insulation, clearance, and switchgear complexity compared to11kVunits.

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 add10%–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.
