Gridtwin Planner

Whole-substation planning studies — see what happens when the entire portfolio connects.

Beyond one project at a time

A single-site analysis asks "what does it take to connect this one project?" A grid plan asks "what happens to this substation when the whole portfolio connects?" Gridtwin Planner simulates existing infrastructure and new projects together, cumulative effects included.

  • The network around the substation imports automatically — feeders, equipment, and service territory
  • Granular modeling of every household, business, or load; tunable parameters for every generator
  • Add new projects from a pre-existing forecast, from your saved studies, or by hand

Two simulation steps

Build the baseline, then interconnect the portfolio.

1 · Build

The existing infrastructure is simulated as the baseline. The network is solved and, where the existing system already has violations, equipment is upgraded until the baseline is sound.

2 · Interconnect

The new projects connect and the plan re-simulates — iteratively finding thermal overloads and voltage excursions, applying upgrades (reconductoring, voltage regulators, capacitor banks, transformers), and re-solving until the network is clean.

With load profiles enabled, every solve is a 24-hour daily simulation using per-project-type load and generation profiles. Each setting — overload threshold, acceptable voltage, regulator spacing, feeder splitting, and more — is configurable per plan.

Before-and-after you can defend

Every plan reports an Existing vs. Interconnected comparison: convergence status and upgrades applied; demand and DER capacity; maximum line loading, minimum bus voltage, energy served, and losses; network element counts — and a Bill of Materials rolling up the cost of every upgrade the interconnection required.

Inspect any line or bus on the map for its simulated voltage, current, loading, and losses.
