- Critical-load resilience
- Energy arbitrage
- Combined operating objective
Load evidence
- Recent electricity bills
- Interval or half-hourly load data
- Peak-demand timing and duration
- Critical-load capacity and autonomy
- Existing solar-generation profile
Electrical and site constraints
- Transformer and switchboard capacity
- Protection and interconnection information
- Available indoor or outdoor space
- Fire, access and environmental constraints
- Single-line diagram if available
Commercial model inputs
- Project horizon and required return method
- Equipment and maintenance responsibility
- Operating and dispatch ownership
- Measurement and verification method
- Decision timeline and stakeholders
How to complete this worksheet
This worksheet has 4 sections: Define the objective, Load evidence, Electrical and site constraints, Commercial model inputs. Work through them in order and tick each item once you have the document or fact. It is written for facilities, engineering and finance teams, so share it with whoever holds each answer. If something is not available, mark it as unknown rather than estimating.
Bills and facility facts show consumption and demand, but not roof condition, switchroom space or cable routes. Those need an on-site check, which Trexon offers as a RM500 commercial site survey credited in full against your project. Typed amounts and selections here are preliminary inputs only.
