The major enhancements made in Stage 3.0 are focused on including existing DER in the analysis and providing sub-feeder level hosting capacity.  Stage 3.0 of the hosting capacity displays will go live on Tuesday, October 1st, 2019.

To support greater stakeholder participation, stakeholders have the option to attend via webinar or in-person.  Stakeholders are encouraged to attend via webinar, using the registration link here. For additional information, please email

Overview of the Stage 2 Hosting Capacity Displays

The Joint Utilities, with guidance from stakeholders in the 2016 engagement group discussions, have developed a four staged Hosting Capacity implementation roadmap.  In response to the March 9, 2017 DSIP Order and building upon the Stage 1 red zone indicator maps, below are links to the Stage 2 Hosting Capacity displays focused on feeder-level analysis of large scale solar PV systems interconnecting to distribution circuits 12KV and above.  Each circuit’s hosting capacity is determined by evaluating the potential for power system criteria violations as a result of large PV solar systems interconnecting to three phase distribution lines with an AC nameplate rating greater than or equal to 300 kW interconnecting to three phase distribution lines.

The JU have provided the following recording from their November 2, 2017 stakeholder engagement group presentation materials as an additional reference to help guide users through the Stage 2 hosting capacity displays.

Central Hudson Gas & Electric’s interactive Solar PV Hosting Capacity map illustrates the areas/circuits where DERs have a greater likelihood of being easily accommodated on the distribution system.

Hosting Capacity for Con Edison can be found through their Distributed System Platform web portal.

National Grid’s stage 2 hosting capacity displays can be found on their System Data Portal under the ‘Hosting Capacity’ tab.  The Stage 2 Hosting Capacity maps supersede the previously displayed Red Zone Maps.

NYSEG and RG&E’s distribution indicator maps for Hosting Capacity stage 2 hosting capacity displays can be found on their Distributed Interconnection Guide Map.

Stage 2 Hosting Capacity for O&R can be found on interactive maps that can be accessed through their web portal by signing into an O&R account or ARCGIS account.
