The process for interconnecting a customer-owned qualifying facility, 20 kW or smaller, to the El Paso Electric (EPE) distribution system is as follows:

1.  DOCUMENT REVIEW
Carefully review the following documents:

2. APPLICATION
To complete the application process please include the following in your application package.  Please wait for approval before starting construction. If the system is built prior to gaining EPE approval, the customer risks paying for a system that does not qualify for EPE incentives. NOTE: Technical review approval of the one line diagram is contigent upon wiring, inspections, and system installation. These must be in accordance to EPE's requirements book and must reflect the information provided in the one-line diagram.

a. Print and complete two copies of the Interconnection Application and one copy of TX Renewable Energy Facility Ownership Status Form.  Sign all originals.

b. With each application the customer shall include a simple one-line diagram and site diagram (similar to the sample above) of the proposed system with each signed original of the Application.

(1) The one-line diagram shall identify all major equipment including the utility-accessible generation disconnect device and the EPE metering point.

(2)The site diagram shall show the physical location of the equipment in relation to the property and location of equipment on the exterior wall.

(3) Please verify the delivered service phase matches the installed generation phase, i.e., single phase service = single phase inverter, 3-phase service = 3-phase inverter. Note: All three-phase Y-connected systems require three-phase connected inverters.

c. Mail all originals for review and approval to EPE at the address listed below:

Renewables Development
El Paso Electric (loc.131)
P.O. Box 982
El Paso, Texas 79960

d. The customer shall install a main disconnect between the revenue meter and the main service panel. This is normally part of the outside main service panel. If not, or if the main service panel is on the inside of the wall, it will have to be added as described above. This insures that, if necessary, the customer can be isolated from EPE’s distribution system. This is a safety precaution for EPE personnel when working on the distribution system.

e. Customer shall also include specification or technical data sheets for all required protective equipment and/or inverters for review by EPE.

f. If there are any questions or concerns about any of the customer-furnished information, an EPE representative will contact the customer to resolve these issues.

g. Upon approval, an EPE representative will contact the customer and the customer can start construction.

3. INSPECTION
After construction of the generation system has been completed and received final electrical inspection by the authority having jurisdiction, the customer must contact EPE at smallrenewables@epelectric.com for an interconnection field inspection and meter installation. The purpose of the inspection is to verify that facility construction conforms to the representation presented in the Agreement and its attachments. Please do not energize your system until after EPE has performed its inspection and replaced the existing meter.

4. SIGNED AGREEMENT
After the interconnection facility has been approved by EPE, EPE will identify the location as an EPEC Distributed Generation (DG) Interconnection site by means of a label on the meter box or adjacent to the meter box. Along with written authorization, EPE will return one of the fully executed Agreement originals to the customer.

5. NET METERING
As a DG metering customer, with an approved Interconnection Application,  you have the option to select the installation of a net meter.  Net consumption is charged at the applicable rate and net production is credited  based on EPE’s Rate Schedule No. 48;
