An Added Facilities Agreement (AFA) will be offered to the applicant/customer outlining the costs, terms and conditions for installing the Added Facilities. There are several AFA options available that will be identified as part of the MOS Study.

MPORTANT INFORMATION:

Sub-transmission service requires a CEQA review under the California Public Utilities Commission’s General Order 131-D.  Where applicant/customer is adding large loads that require environmental permitting, it is generally more expedient to include a description of SCE proposed facilities in the customer’s EIR/EIS.

SCE provides Added Facilities in accordance with Often, as the applicant/customer load addition develops, the corresponding electrical service may also fluctuate.  Therefore, scope of work, cost estimates and schedule are subject to change.  Accordingly, the final recorded cost of the Added Facilities will be based on the actual installed cost.  The below chart depicts the level of cost estimating accuracy throughout the project life cycle

Follow the steps below when contemplating sub-transmission service or to determine if sub-transmission service is right for your business.

1. Download and complete the Method-Of-Service (MOS) study application.
2. Request a meeting with your assigned Account Executive to discuss viability based on rough order of magnitude costs and rate options (based on typical unit costs).
3. If the decision is made to pursue sub-transmission service, a Method of Service (MOS) Study will be performed at the applicant/customer expense.  The MOS Study will determine the conceptual scope of work, cost and schedule for the desired Standard Facilities and Added Facilities.
   1. A preliminary engineer fee (advance) will be collected to develop the estimated cost for the MOS Study.
   2. The applicant/customer will of the provided the estimated MOS Study cost and then be offered an MOS Study Agreement.
   3. Upon completion and delivery of the MOS Study, the applicant/customer will decide whether or not to pursue installation of the requested electric facilities.

There are a number of possible variables including, but not limited to:

• The applicant/customer projected peak demand and the load profile.
• The cost of the Added Facilities compared to the potential rate savings.
• SCE determination of Standard Facilities necessary to serve the projected load.
• Other site specific considerations.

To help streamline the process, please contact your SCE Account Representative or call our Local Planning Department at 1-800-655-4555.

LARGE LOAD QUESTIONS (typically near or greater than 6 MVA)

For large loads, there may be an economic advantage to taking service at a sub-transmission voltage (> 50kV).  The 6 MVA threshold represents an approximate limit to the amount of load that can be served from a single 12 kV or 16 kV distribution line.  Depending upon site specific conditions, it may be more economic for SCE to install sub-transmission facilities rather than a second distribution line.

SCE provides service in accordance with Tariff Rule 2 as authorized by the California Public Utilities Commission (CPUC). In addition to the specific rule requirements, each service request is individually designed taking into consideration factors that include but are not limited to: the customer’s projected electrical load, location of the customer’s metering point, requested service voltage, reliability needs, proximity and delivery capacity of SCE’s nearby facilities, potential for load expansions, and future development of the SCE system.
