All Liquid Biofuels Generation Units:
- Must use Eligible Liquid Biofuels, as defined in 225 CMR 16.00
- May blend Eligible Liquid Biofuels with non-eligible fuels, as long as the blend contains 10% Eligible Liquid Biofuels by volume
- Must qualify as part of an aggregation
- Must deliver a useful thermal load to Massachusetts
For more information on Liquid Eligible Biofuels in the APS, please visit our APS Statement of Qualification webpage.
The size classifications for Eligible Liquid Biofuel Generation Units are as follows:
Eligible Liquid Biofuels
Output capacity less than 1,000,000 Btu per hour
Output capacity greater than or equal to 1,000,000 Btu per hour
Intermediate Eligible Liquid Biofuel Generation Units and Aggregations
Intermediate Eligible Liquid Biofuel Generation Units must be qualified as part of an aggregation. Biofuel distributors, a person or entity who sells Eligible Liquid Biofuel onto an end user, will be responsible for qualifying these Generation Units and retain the rights to all associated AECs. The calculation used to determine the number of AECs for intermediate Eligible Liquid Biofuel Generation Units is as follows:
More information on this calculation can be found in the Guideline on Metering and Calculating the Useful Thermal Output for Renewable Thermal Generation Units – Part 1 (Calculations for Small and Intermediate Generation Units).
Any biofuel distributor who wishes to be a qualifed aggregation under the APS must submit the application below to thermal.DOER@mass.gov.
All qualified biofuel distributors/aggregations will be required to report their Eligible Liquid Biofuel sales on a quarterly basis, using the form below.
Large Eligible Liquid Biofuel Generation Units
Large Eligible Liquid Biofuel Generation Units will receive AECs, based on their metered production, on a quarterly basis. Generation Unit owners should review the Guideline on Metering and Calculating the Useful Thermal Output for Renewable Thermal Generation Units – Part 2 (Metering for Intermediate and Large Generation Units) for information on metering requirements.
All large Eligible Liquid Biofuel Generation Units are required to submit the following in their Statement of Qualification Application through the APS Renewable Thermal Application Portal:
- Site and facility information
- Site plan (attachment)
- Contact information
- Equipment specifications
- Equipment arrangement drawing (attachment)
- Annotated product literature for all major equipment (attachment)
- Design specifications
- Description of system controls and sequence of operations (attachment)
- A process flow diagram (attachment)
- A one line electrical diagram (attachment)
- NEPOOL GIS information
- AEC Service Agreement (optional, attachment)
- APS Renewable Thermal Performance Workbook (attachment)
- Independent Verifier request form (attachment)
- A metering plan including a list of meters (attachment)
- Annotated product literature for each APS meter (attachment)
- Annotated product literature for the Data Acquisition System (DAS) (attachment)
Cap on the Available AECs for Biofuel Generation Units
In each Compliance Year the total number of AECs minted to Generation Units using Eligible Liquid Biofuel may not exceed 20% of the total projected annual compliance obligation for the Compliance Year, in which they are generated, with no more than 10% of the AECs generated prior to July 1. If 100% of the AEC available prior to July 1 are not allocated, the remaining number of available Attributes shall be rolled over and allocated during either of the remaining quarters in that calendar year. If the number of Attributes reported by Generation Units exceeds the available Attributes, the number of available Attributes shall be allocated on a pro-rata basis.
Biofuel Suppliers List
The Department shall develop and maintain a list of suppliers and wholesalers of Eligible Liquid Biofuel on its website, see below. A biofuel supplier or wholesaler must complete and submit an application to the Department to be included on the Department’s Biofuel Suppliers List. Fuel suppliers must be registered in the Environmental Protection Agency’s Renewable Fuel Standard (RFS2), and must verify with the DOER that they produce biodiesel from only organic waste feedstocks. Fuel Distributors will be required to demonstrate chain of custody from the supplier to the customer.
To be added to the list, a biofuel supplier or wholesaler will be required to submit the application below to thermal.DOER@mass.gov:
In additional to the above application, biofuel suppliers and wholesalers will be required to report their Eligible Liquid Biofuel production on a quarterly basis, using the respective form below.
