Why Gridtwin for Energy Developers

Minutes, not months

Automated interconnection analysis returns connectable capacity and line-item costs in about five minutes — re-run scenarios as often as you need.

Avoid dead-end sites

Screen every acre by feeder distance, hosting capacity, and substation ratings, so infeasible sites are dropped before you spend on engineering and applications.

Costs you can act on

Every estimate returns an itemized Bill of Materials priced from utility-specific cost catalogs — real numbers for underwriting, before you file an application.

One platform, both sides of the queue

Developers screen sites with the same network models utilities trust for planning — so everyone works from the same numbers.

It's the model behind the Eversource interconnection portal, where 1000+ registered users screen their own projects. See how it works →

Why Gridtwin for Utilities

A lighter interconnection queue

Developers simulate impacts and costs themselves — fewer pre-applications, and less time and expense for your interconnection team.

Hosting capacity on autopilot

Automate the publishing of hosting capacity maps with consistent updates — no more manual refresh cycles.

See years ahead

Forecast DER growth by ranking millions of potential projects on economics and simulating deployment against real network constraints.
