Please note interconnection applications for solar may be denied if the circuit is full. Arrays greater than 1MW AC will require a level 3 ISO system study (at the ISO timeline) in addition to the TMLP Interconnection study. The direct costs will be passed through to array owner. Thank you for understanding.**
We evaluate all applications in kW AC.
Net Metering is available to commercial and industrial customers owning and operating renewable generating facilities for the purpose of offsetting all or part of the customer’s own electric needs.
TMLP currently has two net metering categories, the first is for customers with generating systems of 1.) 60kW AC or less and 2.) 60kW AC and 2,000kW AC.
Individuals interested in building renewable generating facilities within the TMLP service territory and not fitting this description should contact the TMLP to discuss the possibility of a Purchase Power Agreement. Please contact TMLP’s Lead Resource Analyst at 508-824-3132.
To qualify for our Net Metering program:
- The size of the total system may not exceed 50% of the customer’s highest peak demand for the preceding 12-month period, as determined by TMLP.
- To be eligible for net metering service, the customer MUST own or lease the array or lease the building upon which the array is installed, and the array is encompassed in the building lease. Copy of customer-contractor executed agreement required prior to receiving approval to build. See section 4.1 in the Net Metering Terms & Conditions.
- Projects must be approved by TMLP prior to installation.
- Projects must also be completed by licensed electricians and professional, licensed contractors.
- Customer must sign a net metering agreement and an interconnection agreement (documents available below)
- 1-line diagram must be designed and state, “AC Disconnect will be no further than 4’ from and within sight of the utility meter”.
- Customers who intend to also install a battery backup system alongside their solar installation must also submit the Battery Backup Verification Form (document available below). 1-line diagram must show battery backup, include battery product technical data sheet, and include copy of city/town wire inspector’s approval of referenced battery backup system.
- The availability of net metering to a customer is subject to the terms and conditions contained in the Net Metering agreement and/or tariff.
- TMLP may limit the cumulative generating capacity of all such facilities in its service territory and the availability of this service.
