Halcyon

Halcyon is an AI platform for energy market intelligence. It helps professionals working through the energy buildout, including data center developers, utilities, law firms and consultants, find regulatory and market information quickly and answer complex questions about it. The platform has three main parts. Search covers millions of energy dockets, filings and regulatory documents, with filters for topic, keywords and filing type and plain English follow up questions. Alerts combine search filters with AI analysis so that long filings are summarized by what changed rather than only flagged as new, and Halcyon publishes curated alerts such as geothermal, Texas Senate Bill 6 and data centers powered by gas. Data Subscriptions provide asset level datasets sourced from regulatory filings and updated monthly: a Gas Power Plant Tracker, a Large Load Tariff Tracker covering state level utility tariffs for data centers and other large customers, and a New Substation Development Tracker. Docket Profile Pages are AI generated summaries of regulatory proceedings. The platform suits teams that find energy data too expensive, too stale or too much work to build in house. Prices are not published. Visitors can preview the data subscriptions on the site, and full access to the datasets and the platform is arranged by contacting the company.
