Transmission project investment in the United States and Canada in 2013 will more than double that of 2012, with $14.22bn in projects expected to come online this year, compared to $5.59bn that entered service last year, according to TransmissionHub data.
The 2013 outlook includes 120 projects, comprising 5,426 line miles, that are expected to come online. Of those, 45 projects are estimated to be over $100m each. In 2012, 52 projects were completed, comprising 2,462 line miles. Of those, 14 were over $100m each.
Though the greatest number of line miles that entered service in 2012 belonged to the 345-kV voltage category – 934 miles representing $1.26bn of investment – the greatest investment last year was in three 500-kV projects, representing $2.80bn in 309 line miles.
The three 500-kV projects that entered service were San Diego Gas & Electric’s (SDG&E) Sunrise Powerlink, a $1.9bn, 117-mile project that links San Diego to the Imperial Valley in California; Hydro One‘s $695m, 112-mile Bruce to Milton line in Ontario; and the Bonneville Power Administration’s (BPA) $200m, 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, $205m line that was energized in December; Oklahoma Gas & Electric‘s Hugo to Sunnyside project, a 130-mile, $200m project; and Oncor Electric Delivery‘s Brown to Newton line, a 99-mile, $157m 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 $7bn.
Northeast Utilities‘ (NYSE:NU) $718m, 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) $370m, 192-mile West Shackelford to Navarro-Sam Switch line is the second most costly 345-kV line, and Lower Colorado River Authority’s $311m, 139-mile Big Hill to Kendall project is the third.
After the $7bn investment in 345-kV projects, the second greatest investment is $3.20bn 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 $764m, is the largest by cost, followed by Enbridge’s (NYSE:ENB) Montana Alberta Transmission Line (MATL), a 214-mile, 230-kV project estimated to cost $400m.
Seven 500-kV projects, representing a total of 577 line miles and $2.99bn 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 $697m, 115-mile line from the Devers substation near Palm Springs to the new 500/230-kV Colorado substation near Blythe, California.
Nevada Hydro‘s $684m, 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 $610m.
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 $2.11bn of investment in 2013. Investment in projects to come online this year by companies based in Canada totals about $2.82bn.
In 2013, ATCO Electric, based in Alberta, is estimated to bring online about $1.28bn of transmission projects, and AltaLink to bring online about $832m.
Southern California Edison’s investment in projects to come online this year represents the second highest investment, after ATCO Electric, of $1.15bn.
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$237m, 240-kV, 82-mile project for which ATCO has partnered with AltaLink.
AltaLink, also based in Alberta, will energize $842m in three projects in 2013, the majority of which comprises the Heartland transmission project, a C$610m, 500-kV, 41-mile project in Alberta.

In 2012, the greatest amount of investment was in WECC, with $2.4bn in 485 line miles; followed by SPP, with $997m in 840 line miles; NPCC, with $946m in 291 line miles; TRE, with $636m in 514 line miles; MRO, with $282m in 179 line miles; RFC, with $158m in 107 line miles; and SERC, with $152m in 54 line miles.
Twenty-two transmission projects have been suspended or cancelled recently, totaling $16.82bn, 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 (RTEP), citing reduced growth in customer demand and added generation.
PATH, a $2.1bn, 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 $1bn, 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 (JV) 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 JV was then restructured, with MidAmerican securing full ownership of the MPT project. MidAmerican on Jan. 28 confirmed it was not pursuing the project.
