Co-location of DG Projects

The total capacity of distributed generation systems enrolled in the Adjustable Block Program at a customer’s location will be considered a single system. (For example, three 100 kW systems at a single location will be considered a 300 kW system.) For purposes of determining the system’s REC price, a system’s location is considered to be a single building (regardless of the number of utility accounts at the location) for rooftop installations, and a single property parcel for ground-mounted systems (if a property had both rooftop and ground-mounted systems, it will be considered a single system). Additionally, systems located on multiple different rooftops on the same parcel will be considered a single system if each system is owned by the same entity or its affiliates.

If two or more projects on one parcel are separately owned and serve to offset the load of separate entities, then in order to have these arrays considered as separate projects, an Approved Vendor must provide proof that the occupants are not affiliated entities, and each has a separate utility meter and separate utility billing.


Co-location of Community Solar Projects


  • No Approved Vendor may apply to the Adjustable Block Program for more than 4 MW of Community Solar projects on the same or contiguous parcels (with each “parcel” of land defined by the County the parcel is located in).
  • Co-located projects summing to more than 2 MW of Community Solar may be permissibly located in one of two ways:
    • Two projects, of up to 2 MW each, on one parcel; or
    • One project, of up to 2 MW, on each of two contiguous parcels.
  • Multiple projects up to 2MW in aggregate on the same parcel with the same owner will be considered a single project for purposes of REC pricing as well as size criteria in the case of a lottery.
  • A parcel of land may not have been divided into multiple parcels in the two years prior to the project application (for the Adjustable Block Program) or bid (for competitive procurements) in order to circumvent this policy. If a parcel has been divided within that time period, the requirement will apply to the boundaries of the larger parcel prior to its division.
  • If there are multiple projects owned or developed by a single entity (or its affiliates) located on one parcel of land, or on contiguous parcels of land, any size-based adders will be based on the total size of the projects owned or developed on the contiguous parcels by that single entity or its affiliates. Furthermore, the total combined size of projects owned or developed by a single entity (or its affiliates) on contiguous parcels of land may not be more than 2 MW, or more than 4 MW if co-located consistent with the provisions outlined above.
    •  “Affiliate” means, with respect to any entity, any other entity that, directly, or indirectly through one or more intermediaries, controls, is controlled by, or is under common control with each other or a third entity.
    • “Control” means the possession, directly or indirectly, of the power to direct the management and policies of an entity, whether through the ownership of voting securities, by contract, or otherwise. Affiliates may not have shared sales or revenue sharing arrangements, or common debt and equity financing arrangements.
    • “Contiguous” means touching along a boundary or a point. For example, parcels touching along a boundary are contiguous, as are parcels that meet only at a corner. Parcels, however near to each other, that are separated by a third parcel and do not touch along a boundary or a point are not contiguous.
  • Projects owned or developed by separate entities (meaning that that they are not affiliates) may be located on contiguous parcels. If there is a naturally good location from an interconnection standpoint, one owner should not be allowed to prevent another owner from developing a project in that location.
  • Projects must have separate interconnection points.
