Ran a second check of every entry, reading more local outlets and township records, and settled the questions the first pass couldn't. Added seven entries: a former quarry site in South Hanover Township, Dauphin County; the Industrial Drive data center in Bethlehem; Blue Creek Investments' two sites in Mount Carmel Township; PPL's Natalie transmission line; J.G. Petrucci's Bradford Street data center in Allentown; a postponed proposal from the PAX-1 developers in Monroe Township, Cumberland County; and Keel's Panther Creek campus in Nesquehoning, which now has its own entry apart from Keel's Scrubgrass site in Venango County. Mifflin Township's Outrigger data center is now listed as approved. We corrected the cost of Frontier's gas conversion at Shippingport, the York 2 sale, GE Vernova's Charleroi investment and a special counsel's name in Hollenback Township, and placed NextEra's reported gas plant in Luzerne Township, Fayette County.

Checked every entry on the map for news and new developments since our last check, starting with 900 Conshohocken Road and the rest of Southeast Pennsylvania. Added 49 news stories, 52 timeline events and 6 legal filings, and refreshed the current stage or next step for more than 90 projects. New this round: Upper Burrell, Mount Carmel Township and Taylor Township adopted data center ordinances, Plains Township rejected its overlay district, the Parkland School Board voted to oppose Project Atlas, residents in East Whiteland sent a notice of intent to sue, Union County ordered work stopped on a substation at Great Stream Commons, and Hanover Township, Archbald and Limerick posted new hearing dates. The project cards on the map can now be folded down to one line, and the data download now sits right under the map.

Applied an outside verification review of the whole dataset. Kline Township's Amazon campus moved to Approved after the September 30 vote, Upper Burrell and West Whiteland now show their adopted ordinances, Springdale carries the developer's current 240 megawatts and 652,300 square feet, and seven other records got corrected figures or clearer notes. Added the Hollenback Township landowner rezoning in Luzerne County, which brings the map to 127 entries. Filled in the power source field for every project (it had exported blank), and fixed how counties are counted for projects that span two counties. The open data now documents that sources join on project and source id together, lists the status and event labels actually in use, and gives each prominent individual's project list.

Checked every organization listed on all 126 projects against public records, then searched again for the projects the first pass couldn't fully cover. Corrected more than 85 roles (most often engineers that had been listed as partners, and companies whose involvement has ended), removed 3 links we couldn't support, folded 53 duplicate company records into one each, and added about 370 organization links, including project companies, landowners, buyers and sellers, lenders, attorneys, engineers and consultants. The map now carries 874 organization links across its projects, up from 515.

Released the full tracker as open data under a Creative Commons Attribution 4.0 license: one Excel workbook with a README, data definitions, a relationship diagram, every table and these changelogs, plus the JSON files the map uses.

The map now comes first on its page, with every filter and the state permit tracker in a panel over the map. Added a full screen mode on every device.

Added 28 projects found through the state's data center permit tracker and local reporting, many of them in northeastern Pennsylvania, bringing the map to 126 entries. A research pass filled out thin project records with nearly 1,300 profile fields, nearly 1,100 new sources, more than 750 timeline events and more than 450 news items, followed by a corrections and privacy review. Added a type field so power plants, grid work, pipelines and factories show as related infrastructure, and local ordinances show as their own type.

Recorded the October 15 hearing on 900 Conshohocken Road. Added the Front Street data center proposal in West Conshohocken and ten projects found in the state permit tracker. Marked the Upper Hanover proposal withdrawn and applied October updates across the statewide entries.

Added five projects, including Granville Township in Mifflin County and four proposals in Montgomery, Chester and Delaware counties. Refreshed the state permit tracker to 73 projects. Moved Renaissance Park in Upper Merion and Pennhurst in East Vincent to On Appeal, and updated Limerick, Constellation's Limerick uprate and the East Whiteland record.

Recorded the 900 Conshohocken Road hearing being rescheduled to October 15 and the applicant's updated noise assessment. Corrected how the zoning deadlines are described.

Recorded the canceled September 17 hearing and Montgomery County's request for party status.

Plain-language pass on project descriptions. September updates to the 900 Conshohocken Road record.

Recorded the validity challenge and council conditions dispute for 900 Conshohocken Road, and Senate Bill 1359 with its June 30 committee vote.

Added the state's Data Center Permit Tracker as a map layer, with 57 projects and 108 permit authorizations at the time, linked to our entries where they match.

Checked every map pin against its municipality and corrected three. Added news coverage and sources for entries that had none and rewrote thin records. Recorded the Upper Merion denials of the Renaissance Park sites.

Recorded Plymouth Township Council's 43 conditions and the applicant's substantive validity challenge on 900 Conshohocken Road.

Added the Muncy data center and the Williamsport zoning invalidity resolution in Lycoming County. On July 3, recorded the Smithfield Gateway application in Monroe County.

First public version of the statewide tracker, with detailed profiles for 22 priority projects, local opposition groups and news coverage.

Added the organizations behind the new entries, including The Hanover Company and its HCI DP Land Acquisition in South Hanover Township, Pennsy Supply as the landowner there, Boyle Construction, Paxos and TensorIQ in Bethlehem, and Blue Creek Investments in Mount Carmel Township. J.G. Petrucci, Pennsylvania Data Center Partners and PowerHouse each gained a project. The solicitor layer adds the township, city and special solicitors named in the new entries' minutes and coverage.

Updated counts: organization-to-project links 217 to 220; prominent individuals 30 to 35.

Updated counts: organizations 166 to 172; organization-to-project links 210 to 217; ties between organizations 197 to 201.

Updated counts: prominent individuals 28 to 30.

Added a solicitor layer to the 3D view, just above the map: 137 lawyers who advise the township, borough, city and county bodies deciding these projects, with a line down to each project they advise on and a dotted line up to any organization where the public record ties the solicitor or their firm to a backer. The solicitor data and its 32 recorded ties are new tabs in the open data, each with its source and the result of a second reviewer's check. The 3D view's layers are now defined in one list, so a layer can be turned on or off in one place. Leadership titles for Blackstone and Talen were updated after the review.

Updated counts: prominent individuals 30 to 29.

A verification round across all 126 projects brought the web to 166 organizations and 30 prominent individuals, up from 150 and 17. New backers include the owners behind Aligned, Switch, TierPoint and Edged, Cleveland-Cliffs as the seller of the 900 Conshohocken Road site, and the companies in the Hunlock Creek and Lackawanna Energy Center power plant deals. The person layer now also counts attorneys and representatives by the projects they've actually worked on, which adds Edmund J. Campbell Jr., attorney for 900 Conshohocken Road and two other applicants, Marc Kaplin, attorney for Brian O'Neill's King of Prussia appeals and two other applicants, and Michael Mey, Raymond Rinaldi II and Jim Marzolino in Northeastern Pennsylvania. Added 34 documented ties between organizations, for 61 in all, and a "People on its projects" list to each profile.

Released the Follow the Money data (organizations, their projects and roles, ties between organizations and the prominent individuals layer) as open data under a Creative Commons Attribution 4.0 license. The 3D view now fits the whole stack in the frame at every screen size.

Follow the Money went live in the main menu. Added the 3D whole-web view: projects on the state map, organizations above them and prominent individuals between. The person layer now shows prominent individual drivers of hyperscale data center projects: Brian O'Neill, plus anyone a public profile ties to three or more projects. Added full screen, cleaner labels and a one-web-at-a-time view.

First version, in preview: 150 organizations named in public records as backers, connected to the projects they back, with a profile and scoreboard for each and a corrections form. Applied research corrections, including former owners and partners marked as former, power buyers and partner roles, public company tickers and Calpine's sale to Constellation.
