Jurisdictions covered
- New York City, New York, all five boroughs (New York, Kings, Queens, Bronx and Richmond counties). Partial: Department of Buildings filings that name a data center, filings at nine carrier hotel buildings, and the filings the city links to them.
- Zone J of the state grid, which is New York City: data center requests in the grid operator's queue.
- New York State: the executive order and utility regulator actions on data centers that apply in the city.
The quarter in brief
- No New York City data center is asking to connect to the state grid. At the end of the quarter the grid operator's queue held 0 MW of data center requests in Zone J, which is New York City. Statewide it held 11,143 MW.
- No new data center building or capacity addition was filed in the five boroughs. Every project in the record was filed in an earlier quarter.
- The one new data center building under way is small. Charter's one-story, 2,887 square foot hub in Red Hook received its HVAC permit on 12 August. Its building permit is still in review.
These figures may change before the final edition. The counts cover filings that name a data center or sit in a known data center building, not every city permit. A filing is not space anyone can lease.
What changed this quarter
The grid queue has no data center request from New York City
The state grid operator, NYISO, queues large loads asking to connect to the transmission grid. Its queue at the end of September held 0 MW of data center requests in Zone J, New York City, in every status, including withdrawn ones. Statewide, data centers had requested 11,143 MW, all of it outside the city. A data center fed from Con Edison's local network would not enter this queue. So the zero means no city data center has reached the transmission process, not that none is planned.
The state also moved on large projects. On 14 July the Governor's Executive Order 62 paused state environmental permits for data centers of 50 MW or more until a statewide review is done. On 17 September the Public Service Commission adopted a draft scope for that review. No city filing states a size in megawatts, so the records cannot show whether the order reaches any city project.
The pause is now part of the governor's race. On 23 September City & State reported that Governor Hochul's reelection campaign is running ads on it through Election Day, calling it a one-year moratorium. The ad says her Republican opponent, Nassau County Executive Bruce Blakeman, called the moratorium "crazy" and backs new data centers. The order itself sets no end date, and as an executive order rather than a law it stays in the hands of whoever holds the office.
Charter's Red Hook hub is the only new data center building on file
Charter's building at 233 Conover Street, Brooklyn, is filed with the city as a "Proposed new building for Data Center Hub" (B01128862-I1). It is one story and 2,887 square feet. On 12 August the city permitted its $545,000 HVAC job (B01158069-I1). The new building permit was still in plan examination at the end of September. The city's record dates the building filing 30 March 2026, but a pile job from October 2024 already cites its number, so it may be older. The records do not say who the building will serve. At its size it is a network building, not a colocation campus.
Quarterly filingsQuarterly filing summary
New data center buildings and capacity additions in the covered record set, by the quarter first filed, with the quarter a permit was first issued for them. This is the observed record set, not a census of every city job. Each quarter comes from the same queries, so they compare.
| Quarter | Projects first filed | Of which in a carrier hotel or colocation building | Projects with a permit first issued |
|---|---|---|---|
| Q3 2026 (provisional) | 0 | 0 | 1 |
| Q2 2026 | 1 | 1 | 3 |
| Q1 2026 | 2 | 0 | 2 |
| Q4 2025 | 1 | 0 | 1 |

| Q1 2025 | 0 | 0 | 2 |
A project is one Department of Buildings job, together with any jobs the city files for the same new building. Only work that adds data center buildings or capacity is counted: new buildings, new data rooms and data hall fit-outs, and expansions of data center cooling or power. Replacements, repairs and renovations are not.
The six projects filed since January 2025 are three new data rooms or fit-outs in city offices and an office tower, one hospital expansion, a cage fit-out at 375 Pearl Street, and Charter's building. Counts this small are not a trend.
What to watch
- Charter's new building permit at 233 Conover Street.
- 20 October 2026: comments close on the draft scope of the state's data center review.
- 3 November 2026: the election for governor, between a candidate running on the data center pause and one who opposes it.
- Two bills. The Legislature passed a one-year moratorium on large data center permits on 4 June, unsigned. The Council's data center siting study, Int 0003-2026, has had no hearing.

From the end-use table on the "Load Project Tracking" sheet of the NYISO interconnection queue. It leaves out withdrawn and in-service requests, as the sheet does, and leaves out 745 MW of cryptocurrency mining. Zone J shows 0 MW in every status, including withdrawn. A data center fed from Con Edison's local network does not enter this queue.
State air permits in New York City
New York State's environmental permit applications for New York City (DEC Region 2, DART) include no data center air permit application received since January 2025. Four Region 2 air applications were received in that period, and none is for a data center. The last data center application on record there dates from 2012.
Government actions, January 2025 to September 2026
- City Council. Int 1485-2025, a study of data center siting in the city, was introduced on 25 November 2025 and lapsed at the end of the session without a hearing. It was reintroduced as Int 0003-2026 on 29 January 2026 and remains in committee. The Council held no hearing on data centers in Q3 2026.
- City Planning Commission and Board of Standards and Appeals. No land use application in the Zoning Application Portal data and no application in the Board's data names a data center, through each dataset's latest update.
- New York State. Executive Order 62, 14 July 2026. Public Service Commission order instituting Case 26-E-0045 on large-load interconnection, 12 February 2026, and its positive declaration and draft scope, 17 September 2026. The Legislature's Responsible Data Center Development Act passed both houses on 4 June 2026. The Senate's site lists it as delivered to the Governor and the Assembly's record shows no delivery. It has been neither signed nor vetoed.
Projects reported but not confirmed in city filings (1)
- Unverified project: DataVerge expansion at Industry City, 882 Third Avenue, Brooklyn. DataVerge said it has 1.5 MW available and 3 MW more coming online in Q2 2027, as reported by DCD on 9 June 2026 and datacenter.news on 21 May 2026. No city building or electrical filing at the building since January 2025 describes that work, so the 3 MW, its timing and its permits are unconfirmed.
Coverage, boundary and method
Boundary. The five counties of New York City, which are its five boroughs: New York County (Manhattan, FIPS 36061), Kings County (Brooklyn, 36047), Queens County (36081), Bronx County (36005) and Richmond County (Staten Island, 36085). The city government is the permitting authority in all five. Westchester, Long Island and New Jersey are outside the boundary and are covered by our tri-state edition.
| Authority | Records | Scope | Status |
|---|---|---|---|
| Department of Buildings | Job filings and approved permits | Five boroughs, data center wording; nine carrier hotels; jobs filed for the same new building | Counted. Partial: a job that never says data center, outside the nine buildings, is missed |
| Department of Buildings | Electrical permit filings | Five boroughs, data center wording; twelve data center buildings | Reviewed. None states capacity over 1 MW |
| Department of Buildings | Certificates of occupancy; legacy filings | None | Not collected |
| City Council; City Planning; Board of Standards and Appeals | Legislation, land use, variances | Five boroughs | Reviewed. No data center action |
| State DEC, Region 2 | Air permit applications | Five boroughs | Reviewed. None for a data center |
| NYISO | Large-load interconnection queue | Zone J | Reviewed. 0 MW |
What is counted. Only permitting that adds data center buildings or capacity: new data center buildings, with the jobs the city files for them; new data rooms and data hall fit-outs; and expansions of data center cooling or power. A filing that names a data center counts without a stated capacity, including new power or cooling equipment. Power work that does not name a data center counts only when the record shows more than 1 MW serving one. Replacements, repairs, renovations of existing rooms, permit renewals and amendments are not counted, nor is work whose record does not say it serves a data center.
Carrier hotel buildings. 60 Hudson Street, 32 Avenue of the Americas, 111 Eighth Avenue, 85 Tenth Avenue, 375 Pearl Street, 25 Broadway and 325 Hudson Street in Manhattan; 882 Third Avenue in Brooklyn; and 7 Teleport Drive on Staten Island. These buildings also hold offices and shops, so a filing there counts only when it describes data center work.
Counting. A project is one Department of Buildings job, with its trade filings and amendments, plus any jobs the city files for the same new building. It is dated by its own first filing. A permit counts when the city first issued it, not when it renewed it. Declared values are the city's cost estimates and are never added together.
Certificates of occupancy are not part of this report's New York City record set, so none are listed. That is not a finding that none were issued.
Sources and revisions
Every figure links to the public record it came from: the city's job filing or approved permit, the state's notice or order, or the grid operator's queue. Counts are generated from those records. When this edition is final its figures are frozen: a later correction is added below with its date and reason, and the original figure stays visible.
