Distribution Solar PV Hosting Capacity Map*

Hosting Capacity Analysis Methodology and Assumptions

This interactive map illustrates hosting capacity for Central Hudson Gas & Electric’s distribution circuits. Hosting Capacity is an estimate of the amount of DER that may be accommodated without adversely impacting power quality or reliability under current configurations and without requiring infrastructure upgrades. The analyses presented in these displays provide the feeder level hosting capacity for distribution circuits emanating from a substation at 12kV and above. This map currently depicts Stage 2 of a 4 stage approach for implementing hosting capacity in NY. For more information on the hosting capacity roadmap, please refer to the NY State Joint Utilities’ Supplemental Distribution System Implementation Plan (SDSIP).

Please note that these analyses were conducted under current configurations, without installed DER, and prior to infrastructure upgrades such as: installing a recloser or remote terminal unit at the Point of Common Coupling, replacing a voltage regulating device or controller to allow for reverse flow, substation-related upgrades including 3V0 protection, or other protection-related upgrades. These additional elements are being considered for later phases of hosting capacity analysis.   

For the Stage 2 displays, each circuit’s hosting capacity is determined by evaluating impacts of large, centralized solar PV installations (300kW and greater) along the three phase distribution mainline. These analyses represent the overall feeder level hosting capacity only, and does not account for all factors that could impact interconnection costs (including substation constraints).

Please note that issues related to circuit protection require further analysis to make a definitive determination of hosting capacity. This data is being provided for informational purposes only and is not intended to be a substitute for the established interconnection application process. Additional displays with tabulated data have been included in the form of data pop-up displays to indicate that the hosting capacity may be lower at any given location. As a rule of thumb, the minimum hosting capacity value is indicative of the available hosting capacity across the length of the feeder and most often defined by the hosting capacity value located at the most downstream node from the substation. The maximum hosting capacity value is indicative of the available hosting capacity at a specific location, most often located at the node closest to the substation. The load zone represents the NYISO Load Zone.  More information can be found on the Joint Utilities hosting capacity webpage located here: As previously mentioned, existing DER is not considered in this stage of the hosting capacity analysis, and the data pop-ups are intended to provide additional context to the displays.  For these reasons, the installed and queued DG values in the data pop-ups have been included and will be updated on a monthly basis.

This map does not restrict applications from being submitted for a particular feeder, but rather is a tool to inform applicants on the amount of PV a feeder has the potential to host without the need for significant system upgrades at the customer’s cost.

Using the Map

Once in the map, use the address search tool bar in the top left corner to zoom into a specific address. Each distribution circuit is color coded based on its maximum hosting capacity value. Click on the primary segments displayed to bring up additional information about the circuit including: the circuit’s ID, operating voltage level, number of phases, minimum and maximum feeder hosting capacity values, interconnected and proposed DG in queue, as well as NYISO Load Zone.  Additional information on substation is also provided including: the substation ID, interconnected and proposed DG in queue, prior year substation peak, and 3V0 protection status. A legend can also be found in the top right corner of the map. 

The operating voltage may denote voltages below 12kV such as: 2.4kVLine-Gnd, 4.16kVLine-Gnd, 4.8kVdelta, or 7.62kVLine-Gnd. Hosting capacity values however, are only included for the three phase mainline of distribution feeders which emanate from a substation operating at 12kV and above. Voltages below 12 kV classification indicate locations served by one or two phases, or located downstream of a step-down transformer (e.g. transformation from 13.2kV to 4.16kV).

 *Data as of October 2018. Hosting capacity will be calculated and updated on an annual basis. Interconnection queue data for interconnected and proposed DG will be updated on a monthly basis.
