The Application Process

General Information

If you wish to apply to interconnect your generating Facility using the Simplified Process (25 kW or less 1-Phase or up to 50 kW 3-Phase, inverter-based, IEEE 1547 / UL1741- listed) please fill out the attached application form down to the space for your signature. Once complete, please sign and attach any documentation provided by the generator manufacturer describing the IEEE 1547 / UL 1741 listing for the generator. The process is as follows:

Application process:

  • Interconnecting Customer submits a Simplified Application filled out properly and completely.
  • The electric utility Company acknowledges to the Interconnecting Customer receipt of the application within three business days of receipt.
  • Company evaluates the application for completeness and notifies the Interconnecting Customer within 10 days of receipt that the application is or is not complete and, if not, advises what is missing.
  • Company verifies Facility equipment can be interconnected safely and reliably. Company signs application approval line and sends to Customer. In certain rare circumstances, the Company may require the Interconnecting Customer to pay for minor System Modifications, if so, an estimate will be sent back with the approved application requiring the Interconnecting Customer’s consent to pay for the modifications.
  • After installation, customer returns Certificate of Completion. Prior to parallel operation Company may inspect Facility for compliance with standards which may include a witness test, and schedules appropriate metering replacement, if necessary

Company notifies Interconnecting Customer in writing that interconnection of the Facility is authorized. If the witness test is not satisfactory, the Company has the right to disconnect the Facility. The Interconnecting Customer has no right to operate in parallel until a witness test has been performed or previously waived on the Application Form. The Company is obligated to complete this witness test within 10 days of the receipt of the Certificate of Completion. If the Company does not inspect in 10 days or by mutual agreement of the Parties, the Witness Test is deemed waived.

Contact Information: You must provide the contact information for the legal applicant (i.e. the Interconnecting Customer). If another party is responsible for interfacing with the Company (utility), you should provide his/her/its contact information as well.

Ownership Information: Please enter the legal names of the owner or owners of the Facility. Include the percentage ownership (if any) by any Company or public utility holding company, or by any entity owned by either.

Confidentiality Statement: In an ongoing effort to improve the interconnection process for Interconnecting Customers, the information you provide and the results of the application process may be aggregated with the information of other applicants and periodically reviewed by a DG Collaborative of industry participants that has been organized by the Massachusetts Department of Telecommunications and Energy (DTE). The aggregation process mixes the data together so that specific details for one Interconnecting Customer are not revealed. In addition to this process, you may choose to allow the information specific to your application to be shared with the Collaborative by answering “Yes ” to the Confidentiality Statement question on the first page. Please note that even in this case your identification information (contact data) and specific Facility location will not be shared.

Facility Information: UL 1741 Listed: This standard (“Inverters, Converters, and Controllers for Use in Independent Power Systems”) addresses the electrical interconnection design of various forms of generating equipment. Many manufacturers choose to submit their equipment to a Nationally Recognized Testing Laboratory (NRTL) that verifies compliance with UL1741. This “listing” is then marked on the equipment and supporting documentation.

DEP Air Quality Permit Needed: A Facility may be considered a point source of emissions of concern by the Massachusetts Department of Environmental Protection (DEP). Therefore, when submitting this application, please indicate whether the proposed Facility will require an Air Quality Permit. You must answer these questions, however, your specific answers will not affect whether your application is deemed complete. Please contact the DEP to determine whether the generating technology planned for your Facility qualifies for a DEP waiver or requires a permit.
