Transmission & Pipelines

Hudson Transmission Partners completed the 660-MW Hudson transmission project, which connects New Jersey to Manhattan with a cable beneath the Hudson River.

MISO expanded its reliability coordination services to include eight additional entities: Cleco; South Mississippi Electric Power Association (SME); Louisiana Energy and Power Authority (LEPA); Louisiana Generating (LAGN); and four municipal utilities in the region. Cleco and SME are working toward full integration into MISO’s market operations by December 2013.

Williams Partners completed construction and brought into service a major expansion of Transco, a 10,200-mile pipeline system that transports natural gas throughout the northeastern and southeastern United States. The Mid-South Expansion project provides service to power generators in North Carolina and Alabama as well as a local distribution company in Georgia. The company placed into service the first phase of the expansion (95,000 dekatherms per day) in the fall of 2012, and now has commissioned the second phase (130,000 dekatherms/day). The expansion project consists of approximately 23 miles of new pipeline, a new compressor facility in Dallas County, Ala., and upgrades to existing compressor facilities in Alabama, Georgia, South Carolina, and North Carolina.

Hudson Transmission Partners completed testing its underground and underwater, 660-MW electric transmission project between Ridgefield, N.J., and Manhattan, and has begun delivering power to customers in New York City. The Hudson transmission project route has a total length of about 7.5 miles, with a cable bundle buried under the Hudson River for about 3.5 miles and buried underground for approximately four miles, starting in Ridgefield. The line connects to the Con Edison system at the West 49th Street substation in Manhattan and is capable of providing about 5 percent of New York City’s peak demand. The project began construction in May 2011 at a cost of approximately $850 million and was completed six weeks ahead of schedule.

Constitution Pipeline, a limited liability company owned by subsidiaries of Williams Partners, Cabot Oil & Gas, Piedmont Natural Gas, and WGP Holdings, filed an application with the Federal Energy Regulatory Commission (FERC) seeking approval to construct a 122-mile pipeline connecting the Marcellus natural gas supply in northeastern Pennsylvania with northeastern markets by spring 2015. The pipeline was designed to transport up to 650,000 dekatherms of gas per day from Williams Partners’ gathering system in Susquehanna County, Pa., to the Iroquois Gas Transmission and Tennessee Gas Pipeline systems in Schoharie County, N.Y. Capital costs are expected to reach $683 million. Williams Partners owns a 41 percent share of Constitution Pipeline and, through its affiliates, will provide construction, operation, and maintenance services. 

Distributed Generation & Microgrids

Gen-X Energy Development installed Northern Power NPS 100 wind turbines at the SkyGrid microgrid project in Hawaii.

Gen-X Energy Development installed Northern Power NPS 100 wind turbines at the SkyGrid Energy microgrid project in North Kohala, Hawaii. Northern Power says its NPS 100 wind turbine is designed with voltage, current, and reactive power controls to support microgrids. The SkyGrid project, which has been operating since April 2013, was partially funded by the U.S. Department of Energy through the Hawaii Renewable Energy Development Venture. Gen-X Energy Development plans to replicate and deploy the microgrid solution throughout Hawaii and other island communities.

GE and the Kotzebue Electric Association (KEA), an electric cooperative serving the remote city of Kotzebue and other rural areas of Alaska, have launched a joint project to increase the energy efficiency of several diesel engines powering the coop’s microgrid-scale systems. For the initiative, GE will provide its Clean Cycle heat-recovery system to capture exhaust heat and produce electricity. The combined-cycle upgrade is expected to save Kotzebue more than 46,000 gallons of diesel fuel per year and reduce its energy costs. The unit is scheduled to begin operating in the fourth quarter of 2013.

EVs & Storage

Siemens installed a Sitras SES supercapacitor energy storage unit on the new TriMet Portland-Milwaukie light rail transit line. The southeast Portland Tacoma substation location will host what Siemens says is the first rail-based regenerative braking storage system in the United States. Electricity stored in the system can be used for either energy savings or voltage stabilization during peak demand times. In energy savings mode, the unit stores energy generated by braking rail vehicles and retains it in a capacitor bank until the system can feed it back to the power supply during vehicle acceleration. As a voltage stabilizer, energy is discharged when system voltage falls below a specified limit. The Portland-Milwaukie Light Rail Transit Project is set to open in 2015 and will expand to 60 miles and 97 stations. 

EnerDel commissioned a 5-MW energy storage system (ESS) used for Portland General Electric’s (PGE) Salem Smart Power project, part of the Pacific Northwest smart grid demonstration. The ESS is comprised of five large breakers that bring power in and out of the building, allowing inverters to convert electricity from alternating current (AC) to direct current (DC) during the charging cycle. The DC electricity is stored in lithium-ion batteries, to be used during peak demand periods or as back-up power during a utility outage. The same power system and inverters convert the clean DC to AC as the grid demands. PGE expects the project to be operational for at least 10 years.

Bonneville Power and Puget Sound Energy selected Primus Power to supply grid-scale flow batteries for a Pacific Northwest National Laboratory test project.

Primus Power partnered with the Bonneville Power Administration (BPA) to deliver and support two 250-kW EnergyPods as part of a research and demonstration project under BPA’s technology innovation program. BPA is funding roughly one-third of the total project with shared funding from Puget Sound Energy (PSE), the Energy Storage Program of the U.S. Department of Energy (DOE), and Primus. The consortium is studying the potential installation of grid-scale flow batteries in the PSE electric distribution network. DOE’s Pacific Northwest National Laboratory (PNNL) will develop models of the storage systems to assess their energy and economic benefits and make recommendations on where they should be placed. After the systems are installed, the PNNL team also will help evaluate their actual performance.

Smart Grid & Distribution Automation

The Illinois House of Representatives voted to overturn Governor Pat Quinn’s veto of Senate Bill 9, which accelerates investments by Ameren Illinois and ComEd to improve the electric grid. The action clears the way for Ameren Illinois to continue its modernization action plan, which aims to invest $640 million over a 10-year period to improve the reliability and performance of its electric delivery infrastructure. Similarly, ComEd expects to begin installing smart meters to customers in September 2013, with its rollout continuing through 2021.
