ED3 Customer Owned
Distributed Generation Program

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

Customers who wish to interconnect their generation system to the ED3 electric grid will be required to complete the Application for Customer Owned Distributed Generation (DG) and approval process.

Acceptable Solar Distributed Generation System Sizes:

Minimum: 1,000 Watts DC

Residential Maximum: 10 kW (ten kilowatts) DC

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

Please Note:

A Distributed Generation (DG) System pertains to all applicable distributed energy resources and / or power generating technologies with or without energy storage, whether or not interconnected ED3’s electrical grid.

DG Systems approved under the Solar Power Program 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 Customer Owned DG Program.)

A 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 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 Distributed 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 26 – Schedule of Charges and Fees, or Rider No. 8, included in the Application for Customer Owned Distributed Generation link below.

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.
