Frequently Asked Questions
Still have questions?
How long does a subscription last?
We offer annual subscriptions.
How many users come with a subscription?
Please contact us and we'll work together to find a price that works for your team.
How does the subscription work?
You pick which regions / ISOs you want to subscribe to. There's a different price per region and discounts for multiple regions.
Can we compare your data to studies we've done in the past?
Yes. Before you subscribe, we offer a benchmarking call where we compare Felix results with any studies you've done in the past. If you're interested, please book a demo.
What's the source of your data?
For developers, we request the latest power flow models from each ISO / utility on your behalf to use as the basis of analysis. The data within our applications are the result of ISO and utility-specific power analysis methodologies imposed on top of these models. We use the same software as ISOs and utilities, e.g. PowerGEM’s TARA and Siemens PTI’s PSS/e.
