Instead of: Diesel → Engine → Generator → Load, you can evaluate: Grid / Solar → HoyPrime BESS → Critical Load, with the DG retained as an added layer where a hybrid configuration makes sense.
Engineering It Right
Instead of a Diesel Engine, Evaluate This Architecture
A traditional DG generates power through a diesel engine. HoyPrime stores electrical energy and delivers it when required, with the DG retained where a hybrid setup makes sense.
Traditional DG path
DIESEL→
ENGINE→
GENERATOR→
LOAD
Evaluate instead
GRID / SOLAR→
HOYPRIME BESS→
CRITICAL LOAD
For suitable sites, a hybrid configuration
GRID + SOLAR + HOYPRIME BESS + DG→
CRITICAL LOAD
This lets businesses move toward battery-based backup while retaining the DG for extended-outage requirements where necessary.
Why Move Away From Diesel
Why Replace a DG Set with BESS?
Businesses operating large DG systems commonly face a familiar set of challenges.
- High diesel consumption
- Increasing fuel costs
- Generator maintenance
- Engine servicing
- Fuel storage requirements
- Fuel transportation
- Noise and vibration
- Exhaust emissions
- Generator-room requirements
- Regular testing and operation
- Dependence on fuel availability
A BESS provides a fundamentally different approach: instead of generating electricity through a diesel engine, it stores electrical energy and delivers it when required.

- Utility-scale BESS projects
Not All or Nothing
DG Replacement: BESS or Hybrid?
Not every site should immediately remove its DG. MSEB Power evaluates three possible strategies.
Option 1 — BESS Only
GRID→
HOYPRIME→
CRITICAL LOAD
Considered where the required backup duration and load can be economically supported by BESS alone.
Option 2 — Solar + BESS
SOLAR + GRID→
HOYPRIME→
LOAD
Solar energy is stored and used according to the project's energy-management strategy, reducing dependence on diesel generation in suitable applications.
Option 3 — BESS + DG Hybrid
GRID + SOLAR + HOYPRIME + DG→
LOAD
The BESS handles selected backup and energy-management requirements, while the DG stays available for longer-duration outages, potentially reducing DG running hours, diesel consumption, generator wear and fuel requirements. Actual savings depend on the site's load and operating conditions.
Before You Decide
Can HoyPrime Completely Replace My DG?
The answer depends on your electrical requirement. MSEB Power evaluates the following before recommending a configuration.
- Existing DG capacity in kVA
- Critical load in kW/MW
- Total facility load
- Required backup duration
- Maximum demand
- Load profile
- Starting current of equipment
- Existing UPS system
- Solar generation
- Grid availability
- Future load growth
- Required BESS power and energy
A 10.03 MWh battery does not automatically mean 10.03 MWh of usable backup energy for every project. Usable energy depends on the final system configuration, operating limits, efficiency, state-of-charge limits and other design factors. The project must be properly engineered before replacing a DG.
Sizing It Correctly
Example: Understanding 10.03 MWh
Conceptually, here is how the nominal storage capacity relates to load, before system losses and other operating constraints.
At 1 MW Load
~10 hours
Theoretical energy duration at a constant 1 MW facility load.
At 2 MW Load
~5 hours
Theoretical energy duration at a constant 2 MW facility load.
At 5 MW Load
~2 hours
Theoretical energy duration at a constant 5 MW facility load.
These are simplified illustrations only and should not be used as final BESS sizing calculations. Actual runtime must be calculated from the complete BESS design and customer load profile.
Lifecycle Cost
Compare Your DG Cost with BESS
Before purchasing another DG, it helps to compare the complete lifecycle cost, not just the purchase price.
DG Cost Factors
- DG purchase / replacement
- Diesel consumption
- Diesel price
- Generator maintenance
- Engine servicing
- Lubricants
- Fuel storage
- Fuel transportation
- Operating manpower
- Generator running hours
BESS Cost Factors
- Battery container
- PCS
- EMS
- Transformer
- Switchgear
- Fire protection
- Cooling
- Installation
- Commissioning
- Monitoring & AMC

Don't Oversize
Replace DG Without Oversizing Your BESS
MSEB Power does not recommend selecting a BESS simply based on the size of your existing DG. For example, an existing DG of 5,000 kVA does not automatically mean a 5 MW BESS. The DG and BESS have different characteristics, and sizing must consider these five factors.
Power Requirement
How much instantaneous power is required, in kW / MW.
Energy Requirement
How much stored energy is required, in kWh / MWh.
Backup Duration
How long must the critical loads operate, in minutes or hours.
Critical Load
Does the entire facility need backup, or only selected loads.
Load Profile
How electricity demand changes throughout the day.
