Updates on Hosting Capacity in New York
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. Each of the Joint Utilities (JU) currently shares a PV Hosting Capacity Map and a Storage Hosting Capacity (HC) Map. In April 2023, the utilities are publishing a new iteration of the Storage Hosting Capacity Maps. In fall 2022, the JU completed an analysis refresh of the current iteration of the HC Maps. The JU also continued to progress the overall HC roadmap shown below.
Stage 4.1 of the HC Roadmap: Stage 2 of the Storage HC Maps
As part of stage 4.1 of the Roadmap, the JU is publishing Stage 2 of Storage HC Maps this April. The maps will provide the following.
- Sub Feeder Level for Storage HC Map
- Nodal Constraints (Criteria Violations on PV and Storage Maps
- Cost Share 2.0 Items on PV and Storage Maps
- DG Connected Since Last HCA Refresh
The JU is also providing the following information.
- Six-month update for circuits that increase in DG > 500kW on the PV maps
- Links and/or instructions to access 8760 data
- Storage HC data made available via the API
As part of stage 3.5 of the Roadmap, the JU published Stage 1 of Storage HC Maps in spring 2022. The Storage HC Map shows feeder-level hosting capacity (min/max), additional system data, downloadable feeder-level summary data, sub-transmission lines available for interconnection, and reflects existing DER in circuit load curves and allocations. The storage HC Maps have separate displays for load and generation and are color-coded based on the minimum level of the maximum HC calculated for the feeder. The minimum level of the minimum HC calculated appears on the draw-down pop-up, along with the following information.
- Local Hosting Capacity (MW)
- Substation/Bank Name
- Substation/Bank Rating (MW)
- Feeder Voltage (kV)
The Joint Utilities held a stakeholder session to discuss stage the HC roadmap on November 2, 2022; Click HERE to view the slide deck. During the session, the Joint Utilities provided an overview of the current capabilities of the Battery Storage HC Maps, shared plans for the future of the HC Maps, and welcomed stakeholder feedback! Thank you for continuing to engage and collaborate with us.

Stage 3 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. The most recent release, Stage 3, of the Hosting Capacity displays now includes sub-feeder level analysis of large scale solar PV systems interconnecting to distribution circuits. 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. More information on the analysis criteria, assumptions, FAQs and relevant background can be found in this presentation.
The Joint Utilities have provided the following user demo as an additional reference to help guide users through the Stage 3 hosting capacity displays.
