Hybrid Power
Hybrid DG + BESS
Diesel generators provide critical backup but operate with crippling financial and environmental inefficiencies: diesel power costs can exceed ₹25-40 per kWh, and peak loads force the oversizing of expensive generator assets. Hybridization transforms the DG from a continuously running liability into an optimized backup system.
The battery acts as a shock absorber for the entire power system: it absorbs transient peaks instantly, so the generator runs only in its optimal efficiency band. The result: lower fuel burn, longer DG lifetime, better power quality, and faster response during outages.
How it works
The BESS works as a shock absorber
Nayam's hybrid architecture places the battery between your power sources and loads, so the diesel generator runs only in its optimal efficiency band.
Grid / Solar
Facility Load
Nayam EMS Controller
Diesel Generator
BESS Unit
The battery absorbs transient peaks instantly. The DG operates only in its optimal efficiency band, optimizing runtime and fuel consumption.
The battery acts as a shock absorber for the entire power system, shielding the DG from damaging low-load and highly variable demand.
Energy Management
One intelligent EMS. Four operating modes.
Our intelligent Energy Management System continuously shifts between four modes to secure the lowest-cost power path, automatically selecting the most efficient operating mode.
Instant Ride-Through
Battery delivers instantaneous power during DG startup or failure.
Solar Optimization
Solar powers loads and charges the BESS during the day. The DG remains off.
Zero-Burn Night Mode
BESS independently supplies low-load demand, eliminating inefficient overnight DG runtime.
Peak Protection
Battery covers sudden demand spikes, eliminating DG overload risk and reducing sizing requirements.
The diesel problem
Why diesel-only runs costliest at part load
Conventional generators are sized for rare peak demand but spend most of their service life in a costly, inefficient low-load zone.
- Diesel generator
Indicative trend based on typical commercial generator operation. The 0-30% low-load zone is where fuel efficiency drops and maintenance, carbon build-up, noise and emissions rise.
Comparison
Standard DG vs. Hybrid BESS DG
| Metric | Standard DG | Hybrid BESS DG |
|---|---|---|
| DG Runtime | 100% | 30-60% |
| Operating State | Continuous, vulnerable to low-load damage | Intermittent, optimized for peak efficiency |
| Power Quality | Variable with load spikes | Stable, instant millisecond response |
| Maintenance | High frequency, extensive wear | Dramatically lowered, extended generator lifespan |
| Noise & Emissions | High impact, regulatory risk | Minimized footprint, improved ESG |
Hybrid Economics
Smarter power, lower costs
Hybridization drastically reduces operational friction across all core performance metrics, without replacing your existing infrastructure.
30-70% lower diesel cost
Reduced fuel burn while improving uptime and power quality
1.35-year payback
Estimated payback period in a typical C&I hybrid deployment
30-60% DG runtime
Generator runs only in its optimal efficiency band instead of continuously
