Six utilities, six portals, one map
New York is the best-documented distributed generation market in the country. Under the state's Reforming the Energy Vision proceedings, all six investor-owned utilities publish feeder-level hosting capacity — a genuine advantage for developers, and a genuinely tedious one to use. Each utility built its own viewer, with its own symbology, refresh cadence, and attribute names. NYSEG and RG&E share one between them. None include parcels, ownership, or the interconnection queue.
Screening a region therefore means opening five or six portals, reading each one differently, and then cross-referencing the result against county parcel viewers and a queue spreadsheet by hand. Sungarden normalizes all six onto a single map and puts parcels, ownership, substations, and the continuously monitored SIR queue on top of them.
Territories we've written up
Sungarden loads hosting capacity for all six Joint Utilities. These are the territories we've covered in depth so far.
- National GridUpstate New York — roughly 24,000 square miles from the Capital Region west to Buffalo and north to the Canadian borderFeeder hosting capacity · Parcel ownership · Interconnection queue
- NYSEGRoughly 20,000 square miles — about 40% of upstate New York — in non-contiguous pocketsFeeder hosting capacity · Parcel ownership · Interconnection queue
- RG&EA nine-county region centered on RochesterFeeder hosting capacity · Parcel ownership · Interconnection queue
- Central HudsonThe Mid-Hudson Valley across Dutchess, Orange, Ulster, Sullivan, Greene, Columbia, Putnam and Albany counties, plus parts of Delaware and SchoharieFeeder hosting capacity · Parcel ownership · Interconnection queue
- Orange & RocklandOrange and Rockland counties plus parts of Sullivan and Delaware countiesFeeder hosting capacity · Parcel ownership · Interconnection queue
The territories behave nothing like each other
A statewide search is really several different searches. Across NYSEG and National Grid territory land is abundant and a circuit with headroom is the prize. In Orange & Rockland the system is small enough that queue position decides outcomes, and in Central Hudson terrain and land use disqualify sites the capacity map calls fine.
Frequently asked questions
Who are the Joint Utilities of New York?
The six investor-owned electric utilities in New York: National Grid, Con Edison, NYSEG, RG&E, Central Hudson, and Orange & Rockland. They are not the only utilities in the state — Long Island is served by LIPA through PSEG Long Island, and roughly fifty municipal systems and rural cooperatives serve the rest. None of those are Joint Utilities, and most publish no hosting capacity at all. Under the state's Reforming the Energy Vision proceedings they committed to publishing distribution system data, including feeder-level hosting capacity, through public portals. Each publishes separately, in its own format, on its own schedule.
What is the SIR process?
New York's Standardized Interconnection Requirements — the SIR — are the uniform process for interconnecting distributed generation and energy storage of 5 MW AC or less to a utility's distribution system. Note that the threshold is AC capacity at the point of interconnection, not DC array capacity: a 5 MW AC project may carry close to 7 MW DC. What governs a project is the system it connects to, not only its size — larger distribution-connected projects are handled under the utility's own above-5-MW process, while projects interconnecting to the bulk transmission system go through NYISO's procedures. The SIR sets application steps, timelines, and study requirements uniformly across all six utilities, though each administers its own queue. Confirm the applicable process with the utility against the current SIR.
What is a CESIR and how does hosting capacity relate to it?
A Coordinated Electric System Interconnection Review is the detailed utility study that identifies the system modifications your project requires and estimates their cost and schedule. It is an estimate, not a final price: costs are refined in detailed design and trued up against actual construction, and a CESIR can be restudied if the queue ahead of you changes. Not every project needs one — smaller inverter-based projects that clear the preliminary screens may be approved without a CESIR. Hosting capacity is a screening step that comes before all of this. Worth knowing: the largest CESIR line items are usually station-level and protection scope — station breakers, transformer bank work, direct transfer trip, relay and telemetry upgrades — none of which is visible on a feeder hosting capacity map. Feeder headroom is a necessary screen, not a sufficient one.
Why do I need six different portals?
Because each utility built its own. The data is broadly comparable but the viewers are not: different symbology, different refresh cadence, different attribute names, and in NYSEG and RG&E's case a single shared viewer covering two territories. None of them include parcels, ownership, or the interconnection queue. Sungarden normalizes all six onto one map.
Does New York parcel data come with ownership information?
Sungarden carries statewide New York parcel boundaries, with owner attributes wherever the source county publishes them — owner-name coverage and vintage vary by county, because the statewide layer is aggregated from county submissions. Where it is present, it is what makes capacity data actionable: you can move from a circuit with headroom to the name on the deed without leaving the map.
