Transmission project investment in the U.S. and Canada in 2013 will more than double that of 2012, with $14.22 billion in projects expected to come online this year, compared to $5.59 billion that entered service last year, according to TransmissionHub data.

The 2013 outlook includes 120 projects (totaling 5,426 line miles) that are expected to come online. Of those, 45 projects are estimated to be more than $100 million each. In 2012, 52 projects were completed, totaling 2,462 line miles. Of those, 14 were over $100 million each.

Though the greatest number of line miles that entered service in 2012 belonged to the 345-kV voltage category — 934 miles representing $1.26 billion of investment — the greatest investment last year was in three 500-kV projects, representing $2.80 billion in 309 line miles.

The three 500-kV projects that entered service were San Diego Gas & Electric's (SDG&E) Sunrise Powerlink, a $1.9 billion, 117-mile project that links San Diego to the Imperial Valley in California; Hydro One's $695 million, 112-mile Bruce to Milton line in Ontario; and the Bonneville Power Administration's (BPA) $200 million, 79-mile West of McNary Reinforcement project in Oregon.

Sunrise Powerlink and Bruce to Milton were also the top two most expensive projects of 2012.

The largest 345-kV projects that entered service last year, by cost, were ITC Holdings' (NYSE:ITC) Great Plains (KETA) project, a 227-mile, $205 million line that was energized in December; Oklahoma Gas & Electric's Hugo to Sunnyside project, a 130-mile, $200 million project; and Oncor Electric Delivery's Brown to Newton line, a 99-mile, $157 million project.

For 2013, the majority of the 5,426 line miles scheduled to enter service are 345-kV projects totaling 3,064 line miles, which also represents the greatest investment, or $7 billion.

Northeast Utilities' (NYSE:NU) $718 million, 39-mile Greater Springfield Reliability Project represents the greatest 345-kV investment. The project is one of four that makes up the New England East-West Solution. Lone Star Transmission's and NextEra Energy's (NYSE:NEE) $370 million, 192-mile West Shackelford to Navarro-Sam Switch line is the second most costly 345-kV line, and Lower Colorado River Authority's $311 million, 139-mile Big Hill to Kendall project is the third.

After the $7 billion investment in 345-kV projects, the second greatest investment is $3.2 billion in thirty-two 240-kV or 230-kV projects, representing a total of 1,059 line miles.

ATCO Electric's 149-mile, 240-kV Hanna Regional transmission project, at $764 million, is the largest by cost, followed by Enbridge's (NYSE:ENB) Montana Alberta Transmission Line, a 214-mile, 230-kV project estimated to cost $400 million.

Seven 500-kV projects, representing a total of 577 line miles and $2.99 billion of investment, are expected to come online this year. The largest of these, by cost, is Southern California Edison's Devers to Colorado River project, a $697 million, 115-mile line from the Devers substation near Palm Springs to the new 500/230-kV Colorado substation near Blythe, California.

Nevada Hydro's $684 million, 29-mile Talega to Escondido/Valley to Serrano (TE/VS) (LEAPS) project is the second most costly, and AltaLink's Heartland transmission line is the third, at 41 miles and $610 million.

No 765-kV projects were energized in 2012, nor are any expected to enter service in 2013.

Investment by company

Projects sponsored by Canadian companies ATCO Electric and AltaLink together comprise about $2.11 billion of investment in 2013. Investment in projects to come online this year by companies based in Canada totals about $2.82 billion.

In 2013, ATCO Electric, based in Alberta, is estimated to bring online about $1.28 billion of transmission projects, and AltaLink to bring online about $832 million.

Southern California Edison's investment in projects to come online this year represents the second highest investment, after ATCO Electric, of $1.15 billion.

ATCO Electric has five projects scheduled to enter service this year, including the Hanna Region transmission development project and the Northwest Fort McMurray transmission development project, a C$237 million, 240-kV, 82-mile project for which ATCO has partnered with AltaLink.

AltaLink, also based in Alberta, will energize $842 million in three projects in 2013, the majority of which comprises the Heartland transmission project, a C$610 million, 500-kV, 41-mile project in Alberta.

Southern California Edison's four projects to enter service this year comprise $1.15 billion of investment. The projects are the 500-kV Devers to Colorado River and the Devers to Valley projects, the 230-kV Path 42 upgrade, and the 220-kV Eldorado to Ivanpah project.

Electric Transmission Texas will energize seven transmission projects, all of which are 345-kV, worth $911 million of investment, including the $178 million, 90-mile Clear Crossing to Dermott, the $169 million, 84-mile Edith Clarke to Clear Crossing and the $164 million, 89-mile Edith Clarke to Cottonwood projects.

Suspended projects

Twenty-two transmission projects have been suspended or cancelled recently, totaling $16.82 billion, with the Potomac Appalachian Transmission Highline (PATH) and Mid-Atlantic Power Pathway (MAPP) projects making the biggest headlines in 2012.

PJM's board of directors in August removed the two projects from the RTO's regional transmission expansion plan, citing reduced growth in customer demand and added generation.

PATH, a $2.1 billion, 275-mile, 765-kV line, was a joint venture between Allegheny Energy, which later merged with FirstEnergy (NYSE:FE) and American Electric Power (NYSE:AEP). MAPP, proposed by Pepco Holdings (NYSE:POM), was a $1 billion, 152-mile 500-kV line project that included a 39-mile HVDC undersea cable across the Chesapeake Bay.

Most recently, MidAmerican decided not to pursue the Midwest Power Transmission (MPT) project, which was originally proposed by Electric Transmission America, a joint venture between MidAmerican Energy Holdings and AEP. In December 2012, MidAmerican and AEP told TransmissionHub they did not plan to pursue new projects through Electric Transmission America. The joint venture was then restructured, with MidAmerican securing full ownership of the MPT project. MidAmerican on Jan. 28, 2013 confirmed it was not pursuing the project.
