The ED3 Solar Program is limited to customers served by ED3, who purchase power and energy provided by ED3, and whose solar generation systems are qualified to deliver power and energy back to ED3.

Customers who wish to interconnect their solar system to the ED3 electric grid will be required to complete the Solar Application Packet and approval process.

Acceptable Solar Distributed Generation (“Solar DG”) System Sizes:

Minimum:  1,000 Watts DC

Residential Maximum:  10 kW (ten kilowatts) DC

Small General Service Maximum:  20 kW (twenty kilowatts) DC

          All Solar Customers - Please Note:

Solar DG Systems approved before July 1, 2015, are subject to closed Rider Nos. 3 and 4.  Solar DG Systems approved after July 1, 2015, are subject to the current Rider No. 8.  (Riders are assigned addendums set forth specifically to describe the rules and procedures associated with any series of rates and are not  limited to that of the ED3 Solar Power Program.)

A Solar DG System’s current Rider will remain effective regardless of ownership or location.  Through the District’s application approval and inspection process, these systems can be moved from one location to another within the ED3 service territory. 

Removal of any Solar DG System will be subject to a Site Inspection and Fee.  For more information and fee amounts, refer to ED3’s Electric Service Guidelines, Rules and Regulations – Section 26 – Schedule of Charges And Fees.

ED3 is not responsible for the workmanship or materials of the Customer’s installation contractor, nor does ED3 inspect the installation of the system on your roof.

Some Solar generation interconnections may require a System Engineering Analysis, of which the costs for this service will be borne by the Customer.  This analysis examines existing infrastructure and ED3’s ability to take on additional power generation.  For more information and fees, refer to ED3’s Electric Service Guidelines, Rules and Regulations – Section 27 – Design Deposit Schedule, or Rider No. 8, included in the ED3 Solar Power Application link below.

Customer Applications which are placed in the ED3 Solar Queue are subject to any and all revisions to the requirements of the ED3 Solar Program and Application Process during their time in the Solar Queue.  Applications will be limited to thirty (30) a month on a first-come, first-serve basis.  Any additional Solar Applications received, will be placed in a Solar Queue to be approved the following month.

Any projections of the economic attributes of your system, regardless of the source, are not approved by or binding on ED3. 

All customers may be subject to future rate changes in accordance with the terms and policies of ED3’s Electric Service Guidelines – Rules and Regulations.
