The APS outage map also showed about 150 customers without power in the area Tuesday morning, but power has since been restored, according to APS. The reported reason for those outages was: "An adjoining utility that serves our customers has experienced an interruption in service."
"(ED3) distribution system lost power from the transmission system at 6:41 am with power being restored to our system at 9:14 am. ED3 reached out to our transmission providers, APS and WAPA, and various stakeholders to coordinate a response to the outage. APS dispatched transmission personnel to inspect APS facilities. WAPA and APS both re-energized their transformers on the transmission side. ED3’s system has since been restored including power to all feeders. ED3 continues to investigate the matter and we have requested information from both APS and WAPA," the company said in a press release Tuesday.
The company says: "If customers are still experiencing an outage, ED3 encourages customers to check their breakers. If a customer is experiencing any other issue, they may contact ED3 customer service at 520-424-9021 or by e-mailing ED3 at customerservice@ed-3.org."
The Western Area Power Administration provided the following statement:
“Based on what we know at the Western Area Power Administration, there was an outage along an Arizona Public Service line that tripped one of WAPA's lines. This ultimately resulted in a trip to a line that feeds a transformer, that then feeds into the Maricopa substation. As of this morning, WAPA was able to re-energize its lines back through this transformer, and currently there are no outages affecting WAPA customers.
We do want to emphasize that APS and WAPA teams work closely together because of how interconnected our systems are, and our interservice working agreements means we work to address problems as they arise collectively.”
The Arizona Project Service (APS) provided the following statement:
"APS dispatched crews to assess a power outage in the Maricopa area this morning. By 10 a.m. power was restored to our 150 customers impacted. Our crews found no indication that APS equipment led to the trip of a neighboring utility’s power line serving the Maricopa area. The event is still under further investigation."
ABC15 is continuing to ask questions to learn what truly caused the outage.
