Pattern Energy is developing the Southern Cross transmission project to add a HVDC transmission tie of up to 3,000 MW between ERCOT in Texas and the transmission grid deep in the southeastern United States by 2016. The project cost is estimated at over $1 billion. On December 15, 2011 FERC issued two regulatory orders. The first order directs the City of Garland, Texas and its municipal-owned electric utility Garland Power & Light (Garland) to interconnect the project with ERCOT and directs Texas transmission providers to provide transmission service into and out of ERCOT. The order also contained a clear disclaimer of jurisdiction by FERC, ensuring the continued status quo of all transmission providers and entities within ERCOT as generally exempt from FERC regulation. The confirmation by FERC of the disclaimer of jurisdiction represents a significant regulatory milestone in the development of the Southern Cross project. The second order granted Pattern the authority to sell transmission service on Southern Cross at negotiated rates, and detailed provisions for subscribing anchor tenants and holding an open season as a participant-funded transmission project. This order enables Pattern, through its wholly-owned subsidiary Southern Cross Transmission LLC, to immediately commence anchor tenant negotiations with interested shippers. Construction is expected to begin in early 2018 with an online date of 2021.
