As part of the Reforming the Energy Vision (REV), the state of New York is in the process of transitioning away from simple net energy metering to a scheme which compensates distributed energy resources (DER) based on when and where the energy is generated. That means that a kWh of electricity generated at 5 PM is worth more than one generated at 9 AM, for example, and one generated in a congested part of the city is worth more than say upstate. The new system, formally called the Value of Distributed Energy Resources (VDER), takes all of that into consideration when determining the monetary value of solar exports.
