What is Halcyon?
Halcyon is an AI-powered platform for energy market intelligence that helps professionals navigate the energy buildout and decarbonization efforts. The platform provides automated, always-on energy market intelligence through LLM-enhanced search, allowing users to search millions of energy dockets, filings, and regulatory documents. It combines structured search precision with natural language understanding to answer follow-up questions in plain English.
Key features include free search capabilities with filters for Topic, Keywords, and Filing Type; free Agentic Alerts that combine precise search filters with AI-powered analysis to monitor specific energy topics like geothermal projects, Texas SB6 rulemaking, and gas-powered data centers; and paid Data Subscriptions offering asset-level precision tracking for gas power plants, large load tariffs, rate cases, battery storage, and new substations sourced from authoritative regulatory filings and updated monthly.
Halcyon is designed for energy professionals including developers, strategists, investors, planners, analysts in strategy or policy roles, utilities, and corporations navigating decarbonization business decisions. The platform serves those who spend hours reading energy dockets, parsing through comments, or working with integrated resource plans, helping them raise capital, site assets, and build energy infrastructure faster with better information.
The platform features a custom knowledge graph for streamlined discovery, a natural language interface for defining scope and layering context, and a transparent document library with customizable search filters offering precision and control. Halcyon was founded in July 2023 and raised a $10.8 million seed round from Obvious Ventures, Congruent Ventures, and Overture Climate VC.
