Six ways to cut what your factory spends on energy
Greenwell delivers industrial energy solutions across generation, efficiency, heat, water, lighting and waste — each available under CapEx ownership or a zero-investment OpEx structure.
Our solution lines
Most factories start with one and expand. The free site survey identifies which delivers the fastest return on your particular facility.
Solar PV & BESS
Rooftop solar generation with battery energy storage — the largest single reduction available on most industrial electricity bills.
- LONGi Tier-1 modules
- Huawei SUN2000 inverters
- Battery storage for load-shedding
- Net metering approvals handled
VFD & Motor Efficiency
Variable frequency drives and efficient motors on fans, pumps, compressors and HVAC — typically the cheapest kilowatt-hour a factory can save.
- 20–50% savings on driven loads
- ABB, Siemens, Schneider drives
- Compressor & HVAC optimization
- Short payback periods
Heat Recovery & Steam
Economizers, exhaust gas boilers and steam system engineering that capture energy currently leaving through the stack.
- Custom heat exchangers
- Exhaust gas boilers (EGB)
- Condensate recovery
- Fully insulated steam lines
ETP & Water Management
Effluent treatment plants consume significant power continuously. Optimization cuts that load while keeping you compliant.
- 15–30% ETP energy reduction
- Blower & aeration control
- Sub-metering and monitoring
- Hot water reuse
Lighting & Cooling
Industrial LED retrofits, daylight utilization and efficient cooling — fast to implement, with immediately visible savings.
- Up to 80% lighting energy cut
- Daylight harvesting
- VFD-driven cooling systems
- Improved workplace lux levels
RFID & Auto-ID
RFID inlay and tag supply for Bangladesh's apparel supply chain — matched to specification, imported and supported locally.
- UHF & NFC inlays
- Hang tags & care labels
- Brand-nominated sourcing
- BTB LC import
ESCO and EPC under one roof
Greenwell operates as both an EPC contractor and an Energy Service Company. That means we can build a system you own, or finance and operate one ourselves and sell you the output — whichever suits your capital position.
The engineering does not change between the two. The same Tier-1 equipment, the same design standards and the same commissioning discipline apply whether you are paying for the asset or for the energy it produces.
- Free site survey before any commitment
- Load profiling and measured baselines — not estimates
- IDCOL and commercial bank financing support
- Net metering and regulatory approvals handled
- Long-term monitoring and maintenance
Choose how you pay
Every solution above can be procured three ways — full payment, instalments over 36–60 months, or a zero-investment OpEx model where you pay only for the energy delivered.
Under OpEx, Greenwell carries the capital cost, the maintenance obligation and the performance risk. You carry none.
Not sure which solution fits your factory?
That is what the free site survey is for. We measure, model and tell you where your savings actually are — with no obligation.
