Intro to Halcyon Grids
Build customizable datasets from Halcyon's data — structured analysis at scale
What is a Grid?
A Grid is a tabular dataset you build and customize using Halcyon's data. Each Grid is composed of questions (columns) pointed at a set of documents (rows). The individual cells contain the answers to those questions, drawn from the documents in that row — and you can click into any cell to verify exactly where the information came from.
Put simply: Grids are customizable datasets that let you rapidly build and update structured analyses at scale.
Energy information arrives in high volume and at high velocity. Grids bring familiar, spreadsheet-like structure to that firehose — without the days of manual work it takes to build and maintain a tracker by hand.

How Grids work
Grids are powered by the same engine behind Halcyon Search and Queries, sitting on top of Halcyon's data catalog.
- A row is a set of documents, defined by a search. A row could be a single document, an entire docket made up of many documents, or any set of documents derived from a combination of search filters.
- A column is a query — a natural-language question written to pull information from each row. You choose the response format for each column (a few words, a number, a date, True/False, and more).
- A cell — where a row and column intersect — is the answer: the column's query, run specifically against that row's documents.
Because every cell is generated from source documents, every answer is traceable. Click a cell to see the query that ran and citations pointing back to the original filings.

When should you use a Grid?
There are two common scenarios where we recommend customers use a Grid: if they’re already maintaining a spreadsheet, or if they run a Halcyon query and wish they could quickly replicate it across multiple searches.
Grids collapse the cost of building the market and regulatory intelligence datasets your team already maintains — and make a whole class of datasets viable that nobody builds today because keeping them current by hand is impossible. At the same time, they allow you to answer a question like “what residential VPP programs are active in the U.S.” with a complete list, rather than a few good examples.
Any Halcyon customer that does quantitative research on the Energy sector can benefit from Halcyon Grids. We have proven success cases with Data Center Developers, Solar Developers, Transmission Developers, Utility Equity Investors, Regulatory Teams submitting comments and many other energy businesses where data matters.
(Search, Queries, and Grids are complementary. Use Search to find the documents that matter, and a Query to ask one question of them. Use a Grid when you want to ask multiple questions of the same set of documents — or the same questions across many sets of documents — and keep the answers organized in one structured, sortable place.)
What can you build with a Grid?
Track utility procurement across a whole market. Say you're a utility-scale solar developer evaluating which utilities are good offtake partners. Your market intelligence team tracks how much solar each utility says it will buy in its IRP, how much it has already procured, and how far it is from complying with its state's renewable portfolio standard. Done by hand, that's only feasible for a handful of utilities. A Grid automates the tracking for your existing coverage — and makes the second tier of utilities you'd written off worth tracking.
Analyze every commenter on a key docket. Regulatory teams often build a spreadsheet of every commenter on an important docket, with a summary of each one's stance on key issues — days of painstaking work. A Grid can do it in minutes. And once it exists, you can do something you couldn't before: pull in those same stakeholders' comments from every other docket they've filed in.
And much, much more!
