Do Not Start by Asking:
“How Big a Battery Should We Buy?”
Start with:
“What Problem Are We Trying to Solve?”
For an advanced-energy enquiry, provide the load profile, existing sources, continuity requirement, site constraints and the intended role of generation or storage.
STEP 01 — DEFINE THE OBJECTIVE
Select:
Reduce Fuel Use
Reduce Peak Demand
Increase Resilience
Use More Solar
Reduce Generator Runtime
Support Remote / Off-Grid Operation
Evaluate Microgrid
Other
STEP 02 — LOAD PROFILE
Collect where available:
- peak kW
- minimum kW
- normal kW
- daily energy kWh
- hourly load profile
- seasonal change
- largest motor/load step.
STEP 03 — EXISTING POWER SYSTEM
Identify:
- utility
- generators
- UPS
- existing BESS
- existing PV
- transformers
- switchgear
- fuel systems.
STEP 04 — CONTINUITY REQUIREMENT
Ask:
How long must critical loads remain operational?
And:
Which loads are genuinely critical?
STEP 05 — GENERATOR DATA
Where applicable:
- number of generators
- rating
- duty
- operating hours
- typical loading
- fuel consumption from verified data
- maintenance history.
STEP 06 — RENEWABLE RESOURCE
For solar-related projects:
- existing PV capacity
- available area
- production data if installed
- site location
- curtailment constraints.
Detailed energy-resource modelling can occur later.
STEP 07 — BESS OBJECTIVE
What must storage provide?
Peak Power
Energy Shifting
Short-Term Backup
Generator Support
Renewable Capture
Reserve
Different objectives lead to different designs.
STEP 08 — GRID CONDITIONS
Identify:
- reliable grid
- weak grid
- frequent outages
- no grid
- utility parallel required
- export permitted/unknown.
STEP 09 — FUEL
For generator-based systems:
- fuel type
- supply reliability
- fuel cost
- storage
- logistics.
STEP 10 — COMMERCIAL INFORMATION
Where available:
- electricity tariff
- demand charges
- fuel cost
- annual operating hours
- project horizon.
STEP 11 — ENVIRONMENT
Capture:
- ambient temperature
- altitude
- dust
- coastal conditions
- space
- indoor/outdoor
- access.
STEP 12 — PROJECT OUTPUT
The screening tool should produce:
PROJECT OBJECTIVE

EXISTING SYSTEM
___
LOAD CHARACTERISTICS
___
POTENTIAL TECHNOLOGY PATHWAYS
Examples:
Generator + BESS screening
Solar + Generator screening
Solar + Generator + BESS screening
Grid-connected microgrid study

ENGINEERING FLAGS
Possible outputs:
LOAD PROFILE DATA REQUIRED
BATTERY ENERGY DURATION NOT YET DEFINED
MOTOR TRANSIENT REVIEW REQUIRED
GRID INTERCONNECTION REVIEW REQUIRED

WHAT THE TOOL MUST NOT DO
Never output:
“Install a 2 MW / 4 MWh BESS.”
or:
“You will save 27% fuel.”
without adequate modelling.
PROJECT STATUS
Results should classify the opportunity as:
INSUFFICIENT DATA
More information required.
TECHNICALLY WORTH SCREENING
A deeper study may be justified.
ECONOMIC MODELLING REQUIRED
Technical concept identified but commercial basis unknown.
SPECIALIST ENGINEERING REQUIRED
Complex integration or critical-power project.
COMMERCIAL HANDOFF
Provide the generated brief through:
Call
or project-document submission where implemented.
DO NOT BUY TECHNOLOGY FIRST.
DEFINE THE ENERGY PROBLEM FIRST.

SYSTEM BOUNDARIES
Do not describe:
BMS
as:
EMS
or:
EMS
as:
microgrid controller
without defining the function.
Conceptually:
Battery Management System
Protects/manages the battery system.
Power Conversion System
Converts and controls electrical power.
Energy Management System
Optimises operating strategy.
Microgrid Controller
Coordinates power-system operation across sources, loads and grid/island states.
Specific products may combine functions, but the engineering layers should remain clear.
- power-flow diagrams
- load curves
- solar-production curves
- battery SOC charts
- generator dispatch charts
- operating-mode diagrams
- energy-flow Sankey concepts
- source-state graphics.
Avoid making the visual presentation a gallery of battery containers and solar panels.
The distinctive Reddy visual language should explain:
HOW ENERGY MOVES
and:
WHY THE CONTROL SYSTEM MAKES EACH DECISION
