Development demand scenario
Explore a development load using explicit unit simultaneity, common services and future allowance.
Enable JavaScript for live calculations. Read the method and default example below.
Method and assumptions
- Common services are added after unit simultaneity, without further diversity.
- User-entered simultaneity is a scenario assumption, not a regulatory coefficient.
Before using the result
- Verify phase balance, utility requirements, actual load schedules and protective-device design.
