The state framework sets the default. Where National Grid (NY) pays something different, the utility tariff governs and is what the card above reports.
| Compensation mechanism | Value of Distributed Energy Resources (VDER) Value Stack: monetary credits for net hourly injections, with components for energy, capacity, environmental value, demand reduction value (DRV), and locational system relief value (LSRV). Eligible CDG projects may receive a Community Credit; legacy or qualifying Phase One projects may use NEM-style compensation. |
|---|---|
| Export rate | No single statewide $/kWh rate. The Value Stack is calculated from utility- and project-specific components: hourly NYISO day-ahead energy price, capacity value, environmental value, DRV and, where applicable, LSRV; eligible CDG projects may add a Community Credit or legacy MTC. |
| Rate effective | Value Stack rates are published by each utility for defined effective periods and vary by project qualification date and utility. Con Edison's retrieved Value Stack credit statement is effective June 1, 2026; it publishes separate Phase One and Phase Two component rates. |
| Credit rollover | Value Stack excess credits may carry over to subsequent billing and annual periods under the applicable tariff. For CDG host accounts, unallocated credits may be banked and allocated for up to two years; the banked credit is valued from the Value Stack in the month generated and excludes the MTC. |
| Credit expiration | CDG host banked credits not allocated within the applicable two-year period are lost; other rollover and disposition rules depend on the customer-generator tariff and compensation regime. |
| Annual true-up | No single statewide calendar date: for CDG host accounts, the annual credit reconciliation/allocation occurs after the host's month-12 bill at the 12-month anniversary of commencing CDG net-metered service, under the applicable utility tariff. |
| Aggregate program cap | Utility-specific capacity allocations apply to transitional CDG MTC and Community Credit tranches rather than one statewide cap. NYSERDA's allocation table lists separate MW pools for Con Edison, NYSEG, Orange & Rockland, Central Hudson, National Grid, and RG&E. |
| Program status | NYSERDA's published allocation table marks the listed Community Credit and MTC tranches as closed; the page labels the table current as of October 6, 2021, so a later statewide status was not verified. |
| Grandfathering | Phase One NEM projects receive NEM-style compensation for 20 years from the in-service/interconnection date. Value Stack projects receive compensation for 25 years from the in-service date; qualifying CDG Community Credit and MTC values are locked for 25 years under the applicable rules. |
| Regulator | New York State Public Service Commission (PSC) |
| Governing rule | PSC VDER Transition Order issued March 9, 2017, the Phase One implementation/order framework issued September 14, 2017, subsequent Value Stack compensation order issued April 18, 2019, utility electric tariffs, and the New York State Standardized Interconnection Requirements (SIR). |
