On June 26, 2015, an EPE employee sent an email notifying several employees, including two EPE Marketing Function Employees, that one of EPE’s generators will be coming offline after the peak period on June 26, 2015 for repairs. The email distribution included a prior email in the string of emails that disclosed details about two transmission line outages – a Vista-Sol 115kV line outage on June 26, 2015 and a Vista-Global Reach 115kV line outage on June 27, 2015. The email chain was further distributed to additional EPE Marketing Function Employees before a Marketing Function Employee realized that the email included non-public transmission information and brought it to the attention of his non-MFE supervisor. The information concerning the outages was then posted on EPE’s OASIS as expeditiously as possible. There are no OATT customers on either of the two transmission lines at issue. Therefore, the inadvertent email distribution resulted in no preference to the transmission services accorded EPE, and no discriminatory impact on the transmission services accorded any OATT customer.

On February 13, 2015, an EPE employee communicating by email with other EPE employees and with employees of Tri-State Generation and Transmission Association, Inc. (Tri-State) included two EPE Marketing Function Employees (MFEs) on the email distribution. The email related to the February 21, 2015 scheduled outage of the EPE-owned Luna-Diablo 345 kV line, which had been previously posted on OASIS. The email addressed EPE’s consideration of steps to mitigate the impact of the outage (which involved contacting Tri-State to request that Tri-State study the potential for temporarily opening one of its lines during the Luna-Diablo 345 kV line outage to reduce the impact). 

EPE MFEs did not read the contents of the email. The emails were deleted without delay, due to the quick action of a non-MFE supervisor on the distribution list who noticed the names of the two MFEs shown on the email. The non-MFE immediately went to the desks of those two MFEs, confirmed that neither MFE had yet read the email and confirmed that both MFEs deleted the emails from their inboxes and their recently deleted folders.

Please see EPE’s posting regarding its upcoming Luna-Diablo 345 kV line outage scheduled for February 21, 2015 (www.epelectric.com/transmission/documents). The effects of the outage on EPE’s transmission capability will depend on whether mitigating actions are able to be taken by a neighboring utility.  Once the potential for third-party mitigating actions is determined, any resulting update to the level of transmission capability to be available during the Luna-Diablo 345kV line outage will be posted on OASIS.
