Solar Interconnection Application

If you wish to submit an application to interconnect your generating Facility using the Simplified Process (15KW or less, 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 and send to HMLP@town.hull.ma.us, or print and return to our office.

Note: There is an Application Fee of $100.

Application process:

a. Interconnecting Customer submits a Simplified Application filled out properly and completely. An application fee of $100 must be paid before the witness test.
b. The Hull Municipal Light Plant (HMLP hereafter) acknowledges to the Interconnecting Customer receipt of the application within three business days of receipt.
c. HMLP evaluates the application for completeness and notifies the InterconnectingCustomer within 10 business days of receipt that the application is or is not complete and, if not, advises what is missing.
d. HMLP verifies Facility equipment can be interconnected safely and reliably. HMLP signs application approval line and sends to Customer. In certain rare circumstances, HMLP 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.
e. After installation, customer returns Certificate of Completion. Prior to parallel operation HMLP may inspect Facility for compliance with standards which may include a witness test, and schedules appropriate metering replacement, if necessary.
f. HMLP notifies Interconnecting Customer in writing that interconnection of the Facility is authorized. If the witness test is not satisfactory, HMLP has the right to disconnect the Facility. The Interconnecting Customer has no right to operate in parallel until a witness test has been performed.

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 HMLP, 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.

Facility Information – UL 1741 Listed: 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.
