System Features

  • Net metering Host Customers (i.e., the utility’s customer of record) must begin and submit ACAs. They may assign project Representatives (e.g., developers, consultants, engineers) to help complete an application.
  • Host Customers applying for space under the Public cap will need a DPU Public Entity ID to register with the System of Assurance. See the Help and Guidance page for an application form.
  • The application fee of $100.00 is to be paid electronically before the submission of an ACA. Any user assigned to the project may pay the application fee (e.g., a project developer may pay the fee on behalf of the Host Customer).
  • Once submitted to the Administrator, the review process frequently lasts from 10 to 15 business days. After a determination of complete or incomplete is made, an automated notice will be sent to the Host Customer Entity and any representatives associated with the ACA. If the ACA is determined to be complete, the notice will indicate if a Cap Allocation if a place on the Waiting List is offered.
