Electrical distribution diversity scenario calculator

Calculate coincident demand and overall coincidence fraction with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use coincident demand and overall coincidence fraction to compare changes to your inputs. The method and limits below explain the scope.

Calculation method

Calculation method

Coincident demand (kW)

Sum load×coincidence for independently supplied group factors; no standard default diversity tables.

Overall coincidence fraction

Sum load×coincidence for independently supplied group factors; no standard default diversity tables.

Assumptions & limits

Assumptions & limits

  • User-supplied measurements and assumptions; Sum load×coincidence for independently supplied group factors; no standard default diversity tables. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
