Large-Load Regulatory Tracking
Where the rules for large loads are being rewritten.
Why this exists
A large load — a data centre, an electrolyser, a chip fab — does not just need a wire. It needs to be allowed. What tariff it takes service under, what it must post as security, whether it can be curtailed, and whether it is even eligible are all decided in state commission dockets and ISO tariff filings.
Those decisions are being rewritten right now, faster than the reference material describing them. Georgia's PSC has run proceedings specifically on large-load tariffs; PJM has the Interconnection Request Application Status system and a Large Load Registry. All of it is public, and all of it is published as docket PDFs and process pages rather than as data.
The intent is to track which proceedings are open, what they would change, and when they were last touched — so somebody evaluating a market can see that the rules are in motion before they commit, rather than discovering it during negotiation.
What gets tracked
Docket numbers, filing dates, filing parties, and the stated subject of each filing. The plan is a record of what exists and when it moved, not a summary of what it means — legal interpretation is not something a pipeline should be doing.
Why a registry matters
PJM's Large Load Registry and IRAS expose where large-load requests have been made. That is a leading indicator of where interconnection attention and competition are concentrating, distinct from the generator queue this site already tracks.
The obvious risk
Regulatory text is easy to misread and expensive to misreport. Anything published here will quote the filing and link to it, and will not characterise a proceeding's likely outcome. Where a docket is ambiguous, it will be labelled ambiguous.
Current state
Scoping. Sources are identified and reachable; nothing is being ingested yet, and there is no publication date. Georgia and PJM first because the filings there are the most active, not because they are the only ones that matter.
This is the project most likely to change shape as it is built, because the right unit of publication — docket, filing, or issue — is not yet obvious.
The other pipelines
Same rule everywhere: a figure ships only when it traces to a named public source. Roadmap →
Queue Wire
A weekly diff of the PJM and ERCOT queues. Not another copy of the queue — a record of what changed between two published snapshots.
Substation Expansion Tracker
Parsing PJM RTEP and TEAC filings for planned substation additions and upgrades — something a point-in-time snapshot cannot tell you.
Large-Load Regulatory Tracking
Georgia PSC tariff dockets, PJM IRAS, and the Large Load Registry. Public filings that decide what a large load is allowed to do.
Behind-the-Meter & Co-location
Filing and territory patterns that indicate behind-the-meter or co-located load. Detection is indirect, so these stay indicators.
