1. Edison's motion to accept its comments to the Eligibility Supplement one day out of time should be granted.
2. The use of dynamic load profiles for the three major electric utilities in this state will result in uniform load profiling methodologies throughout most of the state, and will result in improved accuracy of the load profiles.
3. The UDCs' proposal to use static load profiles on an interim basis for the majority of the customer classes, and Edison's use of dynamic load profiles for its residential and small commercial and industrial customers, should be adopted.
4. Until the Commission resolves the issue of how direct access affects master metered customers and sub-metered customers, a static load profile for master metered customers should not be offered.
5. The UDCs should take action immediately to ensure that dynamic load profiling is in place for all the customer classes, except for agricultural customers, street lights and traffic lights, no later than July1, 1998.
6. Unless exempted from having to provide direct access to its customers, Kirkwood, PacifiCorp, Sierra Pacific, and SCWC remain obligated under Ordering Paragraph 5 of D.97-05-040 to provide load profiles to its customers with loads of less than 20 kW.
7. The issue of whether other entities should be allowed to create and design load profiles should not be addressed at this time, but should be revisited in 1998.
8. The UDCs should make all street lights, regardless of ownership, eligible for direct access using deemed load profiles.
9. The UDCs should be permitted to require in their tariffs and profiles that the customer must meet or exceed the photocell maintenance requirements of the UDC in order to be eligible for direct access using that load profile.
10. The photocell maintenance requirement is reasonable because it helps to ensure that the street light usage is consistent with the estimate of usage in the deemed load profiles.
11. Since electricity usage for traffic lights is fairly consistent, SDG&E's use of a static load profile for its traffic lights accounts should be permitted since the usage is unlikely to vary much from a deemed load profile.
12. In deciding whether load profiles for customers with a maximum demand of 20 to 50 kW should be permitted, the Commission should weigh the cost and availability of hourly interval meters, and what may happen if the Commission allows or does not permit the use of load profiles for this customer group.
13. The interim blanket exemption proposal of PG&E and SDG&E should be adopted because it will permit those customers who fall within the 20 to 50 kW range to examine the costs and benefits of moving toward an hourly interval meter, while being able to use load profiles on an interim basis.
14. The interim blanket exemption will provide an opportunity for market forces to determine how much hourly interval meters should cost, and allow the supply of such meters to match the demand.
15. Interim load profiling for 20 to 50 kW customers is equitable given the uncertainty over the cost and availability of hourly interval meters, and is consistent with the provisions of Section 365(b).
16. To access the impact of the metering requirement on 20 to 50 kW customers, the Commission should convene a workshop no later than May30, 1998.
17. For 1998, the UDC is the only approved provider of metering and meter services for customers who take service on load profiles, unless the customer already owns a meter capable of providing data for direct access, but chooses to take direct access from a load profile instead.
18. To the extent load profiles are used in a transaction over which we have jurisdiction, the same load profile that a given customer uses should be used for all applications.
19. The UDCs should develop a plan to place more meters at strategic points in the transmission and distribution system to detect where the UFE losses are occurring, and who is responsible for the losses.
20. The Commission needs to revisit a number of load profiling issues in 1998.
21. To assess the effects of load profiling, and to determine how load profiling methodologies and administration can be improved, the Commission needs to monitor the data associated with the use of load profiles for direct access.
22. Consistent with D.97-05-040, the UDCs may record in the IRMA subaccounts the costs that are attributable to the implementation of direct access.
23. The booking of costs to the IRMA subaccounts is no guarantee that the UDCs will be entitled to recover these costs.
IT IS ORDERED that:
1. The motion of Southern California Edison Company (Edison) to accept its comments to the Eligibility Supplement one day out of time is granted. The Docket Office is directed to file Edison's comments to the Eligibility Supplement as if it was filed on August11, 1997.

(1) Such a status report shall also inform the Commission as to what steps they will take to ensure that dynamic load profiling can be in place beginning on July1, 1998, as well as the estimate of the costs that they anticipate spending to institute load profiles.
(2) Interested parties may file comments on the status report within 21 days of the status report's filing date.
c. Edison shall be required to file and serve a status report within 30 days from today's date on what steps it needs to take to ensure that dynamic load profiling can be instituted for the other customer classes described in this decision by July1, 1998.
(1) The status report shall also estimate the costs that Edison anticipates spending to institute the remaining dynamic load profiles.
(2) Interested parties may file comments on the status report within 21 days of the status report's filing date.
d. Edison shall make its dynamic load profiles for its residential and small commercial and industrial customers available to others starting on November1, 1997.
