FYI - the Australian Energy Regulator has implemented a similar concept to the NY VDER. It is called the Customer Export Curtailment Value (CECV). The CECV places a value of DER exports and requires the local networks to augment the grid when the cost of doing so is less than the overall benefit of more DER generation.
Also note that there are a large number of ways that non-network services can be procured...
1. Tariffs/rates that are dynamic and/or locational
2. Direct procurement (contracting)
3. Flexibility platforms for trading NWAs
Each approach has pros and cons. The future probably requires some rates/tariffs working in tandem with some sort of procurement platform.
