What engineers say

Electrisim gives me the load flow and short-circuit results I trust, without the four-figure annual licence I used to pay. The browser workflow is faster than launching a desktop tool.

Power Systems Engineer

Renewables consultancy · EU

Validated against Neplan in a master’s thesis at the University of Palermo — load flow and short-circuit numbers match. That gave us the confidence to use Electrisim for grid studies.

Academic Reviewer

University of Palermo

Drag-and-drop modelling, dual pandapower/OpenDSS engines, and a one-click engineering report PDF after every run. At $5/month it’s a no-brainer for our small team.

Billing & subscription FAQ

Everything you need to know before you subscribe.

Yes. You can cancel in one click from the Stripe billing portal at any time. Your subscription stays active until the end of the current billing period — no questions, no retention calls.
Billing is handled by Stripe. You’re charged $5 (USD) every month on the day you subscribed. We never see or store your card details — Stripe handles that with industry-standard encryption and PCI compliance.
Stripe automatically retries the payment for several days and emails you to update the card. Your access continues during the retry window. If the payment still fails, your cloud access pauses — your models are kept safe and re-activate the moment your card succeeds.
No. The Professional plan runs entirely in your browser at app.electrisim.com. No downloads, no Python setup. If you prefer a local install, the Community Edition is free and fully open source on GitHub.
You can export every model as a file at any time, and the Community Edition reads exactly the same format. Cancel and run your saved studies on your laptop forever — your work is yours.
Yes. Connections to Electrisim are over HTTPS, and Stripe handles all payment data so we never store card numbers. See our privacy policy for details.
If something goes wrong in your first month, email us and we’ll make it right — including a refund where it makes sense. We’d rather have happy users than awkward charges.
For teams, multi-user collaboration, training, on-premise install, or a custom annual contract, see the Enterprise tier above and contact sales. We reply within one business day.
