Solar PV Interconnection & the Muni Solar Rebate Program


ELD customers interested in pursuing the new Muni Solar Rebate Program are encouraged to review the ELD's Solar Interconnection Process & Application document.

Please be aware, those pursuing the Muni Solar Rebate Program should consider both the ELD’s requirements for Interconnection, which are detailed in our Distributed Generation Net Metering Policy, and the DOER’s requirements for the incentive program. The following bullets highlight some of the most notable requirements for each of those programs. Customers and their installers should still review the above documentation as this list is not all-inclusive.

ELD’s Requirements for Solar PV Interconnection
  • System Size limited to 10kW (DC) for residential customers and 30 kW (DC) for commercial customers.
  • Expected production cannot exceed 90% of average load determined by most recent 12 months of billing history. Where the most recent 12 months of billing history does not reflect average load because building was unoccupied or because load is expected to increase (i.e. due to purchase of EV or installation of heat pump), a proforma load estimate completed by a certified electrician may be submitted.
  • Additional requirements detailed in the ELD’s Distributed Generation Net Metering Policy and the attached guidance document
DOER’s Requirements for the Muni Solar Rebate Program
  • Have a capacity of 25 kW DC or less.
  • Have no more than 20% reduction in output due to shading.
  • Have an azimuth between 90 (east) and 270 (west) degrees.
  • While individual municipal utilities are allowed to have additional, more stringent requirements for Rebate eligibility, the ELD does not to have any additional requirements other than its minimum requirements for Solar Interconnection.
Note on Incentive Calculation
In addition to the $1.20/watt base incentive being jointly funded by the ELD ($0.60/watt) and the DOER ($0.60/watt), Ipswich customers are also eligible for an additional $0.30/watt adder for the first 10kW of their systems. In other words, systems up to 10KW will receive a rebate of $1.50/watt. Larger systems will receive $1.50/watt for the first 10kW of their systems and the $1.20/watt for all installed kW above 10kW. The table below demonstrates the expected incentive amount across a range of system sizes.

Scheduled EV Charging Pilot Program

 
The Electric Light Department (ELD) has purchased 12 ChargePoint Level 2 Chargers and is giving them away for free to electric vehicle (EV) owners as part of our Scheduled Charging Program.  In exchange for the free charger, EV owners are allowing us to suppress their charging rate during hours of peak demand (weekdays 5:00PM - 9:00PM) for the duration of the 3-year term of the program. 

We still have 4 chargers left for customers who wish to participate in this program. You can start the application process by calling the program hotline at (413) 589-0141, or by emailing EV@mmwec.org.
