Siemens Energy completed the EstLink 2 project, a high-voltage direct current (HVDC) link consisting of converter stations in Anttila, Finland, and Püssi, Estonia. Power is now being transmitted by Fingrid, the transmission system operator in Finland and the Estonian transmission system operator Elering. The new joint transmission capacity between the two countries is now increased from 350 MW to 1000 MW. Siemens was responsible for designing the HVDC system as a monopolar connection with metallic return conductor.
The Pennsylvania Public Utility Commission approved PPL Electric Utilites’ proposed Northeast Pocono Reliability Project, a $335 million project that involves building new electrical substations and a new 230-kV power line running approximately 60 miles. PPL Electric Utilities submitted the project to the PUC in late December 2012, after soliciting public input at 13 community meetings in the project region. The utility is working with various agencies to secure necessary environmental permits. The project is estimated to be completed in 2017.
PAR Electrical Contractors, a Quanta Services company, was selected by Southern California Edison to complete construction of segment seven and portions of segment eight of its Tehachapi Renewable Transmission Project (TRTP) in California. PAR's scope of work under the contract includes the installation of double circuit 500-kV overhead transmission line, environmental mitigation and compliance, foundation installation, tower erection and conductor installation.
The Northern Pass, a proposed transmission line carrying renewable hydroelectric power to New Hampshire and New England, cleared a regulatory milestone by securing 'I.3.9 approval' by ISO New England, the operators of the region's power grid. The I.3.9 process determines whether Northern Pass can reliably interconnect with the New England grid.
After more than two years of planning and training, MISO integrated a four-state region of the electric grid across the South into its existing footprint in the Midwest. The change in control, or "cutover," extends MISO's operational and market footprints from the Gulf of Mexico all the way to Manitoba, Canada.
Entergy utility operating companies completed the integration of their transmission system into the Midcontinent Independent System Operator (MISO). Entergy's utility operating companies — Entergy Arkansas, Entergy Mississippi, Entergy Texas, Entergy Louisiana, Entergy Gulf States Louisiana, and Entergy New Orleans — have been working for more than two years to plan and prepare for the transition. With the integration into MISO, these functions will now be managed by MISO across its newly-expanded regional footprint.
Entergy and ITC Holdings mutually agreed to end their pursuit of a spin/merger of Entergy's transmission business with ITC. The companies formally terminated the merger agreement and filed pleadings to withdraw the remaining transaction approval applications with Entergy's retail regulators, as well as the Missouri Public Service Commission and the Federal Energy Regulatory Commission. The companies originally announced the deal on Dec.
PJM approved a $1.2 billion 345-kV double-circuit transmission investment designed to resolve short-circuit concerns in northern New Jersey.
Xcel Energy began work on a new substation in the town of Brunswick, Wisconsin. The substation will tie into an existing transmission line. Xcel Energy received all state regulatory approvals in early November, and construction work began in late November. The substation is scheduled to be in service by April 2014 and is estimated to cost $4 million.
Electric Transmission Texas (ETT) energized the last of seven 345-kV transmission line projects associated with the Competitive Renewable Energy Zones (CREZ) initiative in west Texas. The Edith Clarke to Cottonwood transmission line was energized to the Electric Reliability Council of Texas (ERCOT) grid on Dec. 4.
