Here are the aggregation rules from our operating procedures (6.3 Small Project Reporting & Aggregation).
• The nameplate capacity of each Generating Unit is less than
250KW;
• The total nameplate capacity of the Aggregated Project cannot
exceed 5 MW.
• The Generating Units being aggregated are located in the same
geographic region (as determined by the Administrator);
• The Generating Units being aggregated utilize the same
Technology/Fuel Type.
It is highly recommended that account holders who register their aggregation compile their full list of generating unit owners before submitting their aggregation registration. If they do not, it will make the process lengthier for account holder. If you continue to add generating unit to the aggregation after it has been approved, it will be moved to a suspend certificate creation mode as there is new information that needs to be reviewed for approval by the administator.
This type of scenario will not result in faster approval since it was already approved, it will make the process longer and can result in delays to approve the aggregation again. In a suspend certificate creation mode, aggregated assets cannot have RECs issued until the TIGRS administrators approve the asset. Please ensure when you are adding to the aggregation that you are adding multiple generating units instead of one by one, as it will results in delays for approval as there are numerous accounts/assets that are approved daily.
Additionally, if your aggregated asset was approved/billed as a small generator, you will not receive an refund if you remove generating units from the aggregation. Conversely, if you move from a micro generator to a small generator you will not be upcharged. The system will recognize the new nameplate capacity for the next annual period and charge accordingly.
