Halcyon is an AI-powered energy market intelligence platform designed to help energy professionals navigate the buildout and accelerate decision-making. Its software brings together searchable regulatory documents, structured data, and AI analysis to make complex energy information easier to find and interpret. Users can search millions of energy dockets, filings, and regulatory documents by topic, keywords, or filing type, then ask follow-up questions in plain English. Halcyon’s Agentic Alerts combine customizable search filters with AI-powered analysis to highlight meaningful changes in lengthy filings.

The company also offers monthly data subscriptions built from authoritative regulatory filings, providing asset-level information on gas power plants, large-load tariffs, rate cases, battery storage, and new substations. Its trackers cover planned U.S. gas plants and substations, as well as utility tariffs for data centers and other large-load customers. Halcyon publishes energy-sector content through its Nameplate podcast, Machine Readable blog, and What’s Happening in Energy blog. The platform and services are intended to help teams access timely market intelligence and improve productivity.
