Two shifts. Six days a week.
Beneath the busy streets of North Jakarta.
That is the operational rhythm of the Jakarta Sewerage Development Project.
At its core, a Microtunnel Boring Machine operates continuously—without interruption.
This machine requires up to 566 kW at peak load.
There is zero tolerance for power failure.
In such conditions, a single electrical disturbance can halt the entire operation.
The Real Challenge: High and Fluctuating Power Demand
The issue is not just the magnitude of power.
The real challenge lies in load fluctuation.
This variation causes generators to operate inefficiently.
Most of the time, they run far below their optimal capacity.
This difference makes the generator inefficient.
Most of the time, the generator operates far below its optimal capacity.
Turning Point: Transition to AMPD 400H
The project team began searching for a better solution.
The answer: AMPD 400H
A Battery Energy Storage System (BESS) designed to stabilize and optimize power usage.
🔋 Technical Specifications: AMPD 400H
| Parameter | Capacity / Value |
|---|---|
| ⚡ Nominal Power | 386 kW |
| 🚀 Overload Capacity | 585 kW |
| 📈 Surge Current | Up to 904 A |
| 🔋 Battery Capacity | 430 kWh |
| ⏱️ Response Time | Milliseconds (Instant) |
How AMPD 400H Works
AMPD 400H acts as an energy buffer:
- Stores energy during low load conditions
- Releases energy during peak demand
- Maintains voltage stability
- Responds in milliseconds
Unlike conventional generators, there is no delay in response.
Real Results on Site
After deployment and commissioning at the Pluit site:
Operational Performance
| Parameter | Target | Actual |
|---|---|---|
| System Uptime | >99% | 99.9% |
| Power Interruption | 0 | 0 |
| Noise Complaint | 0 | 0 |
| Regulatory Issues | 0 | 0 |
Financial Performance
| Cost Component | Diesel (Generator) | AMPD 400H | Potential Savings |
|---|---|---|---|
| Fuel Cost / Month | 180 – 220 Million IDR | 120 – 145 Million IDR | 60 – 75 Million IDR |
| Generator Rental | 45 Million IDR | 0 | 45 Million IDR |
| Maintenance | High | Low | ±87% Reduction |
| Total OPEX Saving | — | — | 30% – 35% |
Why AMPD 400H Is Effective
There are several key reasons:
1. Ultra-fast response time
The system reacts within milliseconds.
2. Stable power output
No voltage drop during load spikes.
3. Low noise level
Ideal for urban environments.
4. Zero onsite emissions
Environmentally friendly operation.
Relevance for Mining Applications
This project shares strong similarities with mining operations:
- Fluctuating load profiles
- Continuous operations
- High risk of downtime
This is why energy storage systems in mining are becoming increasingly relevant.
More Than Just a Generator Replacement
AMPD 400H is not merely a substitute for generators.
It delivers:
- Power stability
- Cost efficiency
- Reduced operational risk
For modern projects, this is becoming the new standard.
