BACKGROUND

SCE's Schedule Experimental WTR (Wireless Technology Rate) became first effective November 1999. It allows devices rated up to 700 watts (W) to be mounted on SCE facilities, and applies to "single phase service for wireless technology industries that require electric service to operate radio repeaters or similar devices that are mounted on existing SCE facilities ...and are unmetered". SCE reported that in practice however, it was not applying Schedule WTR to WiFi Internet (WiFi) devices.

Cities, counties and commercial WiFi service providers have approached SCE regarding the attachment of WiFi devices to SCE's streetlights and the powering of these devices with unmetered electric energy so that these entities can make wireless Internet service available within the communities they serve.

SCE conducted a pilot study to evaluate the feasibility of allowing the attachment of WiFi devices to SCE's streetlights. Of concern was (1) the "power quality" served to streetlights when WiFi devices were attached, (2) potential for radio frequency interference (RFI) with radios used in operating SCE's electrical system, and (3) interference with operation of other utility equipment or impact on the service to customers.

The pilot study was necessary because SCE's primary obligation is to operate and maintain its electric system, including the 615,000 owned streetlights out of a total of 780,000 in their service territory. Seventy percent of the owned streetlights are stand alone, loop fed by 120 volt circuits, where the power quality concern is greatest. The pilot was performed over a two-month period on 36 streetlights and five streetlight circuits on a 0.2 square mile area.

The results of the pilot showed that 35 watts of additional load on 50% of the streetlights, (on every other adjacent streetlight) can be accommodated without adverse impact.

Since the pilot was not inclusive of every type of WiFi equipment available on the market, SCE reserves the right to test or have tested by third parties, devices not included in the pilot, at the WiFi provider's cost. Both parties must be satisfied with the test results of a pre-service test of the devices.

Installation of WiFi devices located adjacent to any SCE private WiFi (radio frequency) network must reflect consideration of the following design options to minimize the radio frequency interference between them:
