EPC contractor Gemma Power Systems ordered two H-class gas turbine power blocks from Siemens, for a Panda Power combined-cycle project in Pennsylvania.

ABB delivered the East West Interconnector, a 500-MW capacity HVDC-light underwater power link, to EirGrid, the Irish transmission system operator. The new line connects the Irish and U.K. grids, enabling cross-border power flows to enhance grid reliability and security, and to facilitate power trading between Ireland, England, and the European grid. As Ireland expands its wind power capacity, it’s expected to export surplus electricity, and import power when required. 

Ameren Transmission Co. of Illinois (ATXI) received approval from the Illinois Commerce Commission (ICC) to build the majority of its 400-mile, $1.1 billion, Illinois Rivers transmission project. The project consists of a new 345-kV transmission line crossing the Mississippi River near Quincy, Ill., and continuing east across Illinois to the Indiana border. ATXI expects to begin acquiring rights-of-way for the approved portions of the project immediately, with construction proceeding in 2014.  

The Midcontinent Independent System Operator (MISO) became one of the first grid operators to use new synchrophasor technology in its real-time system operations for grid monitoring and analysis. Synchrophasor technologies use phasor measurement units, or PMUs, to collect data from more than 344 installed devices, 30 times per second, compared to traditional technology, which records measurements every four seconds. The data is GPS time-stamped, enabling measurements from different locations to be time-synchronized and combined to create a detailed, comprehensive, wide-area assessment of system conditions. With the data MISO can better detect, diagnose, and prevent system disruptions, in effect, creating a smarter grid. 

Also, MISO launched its new locational marginal pricing (LMP) contour map, providing market participants with tools for detailed visualization of real-time market conditions. The new map provides more detailed information and interactive tools than MISO’s old map did. It also includes a historical playback feature, allowing users to review the past 48 hours of market conditions.

MISO released its new locational marginal pricing contour map, which provides a detailed visualization of real-time market conditions.

Xcel Energy plans to spend $108.9 million on high-voltage transmission line projects to boost reliability and capacity to serve growing demand in the eastern and northeastern Texas Panhandle. These and other transmission enhancement projects across the region were identified as necessary improvements in a 2010 study by the Southwest Power Pool (SPP). By 2015, the company expects to spend more than $2 billion upgrading generation, transmission, and distribution facilities in the area.

Electric Transmission Texas (ETT) energized the first of seven 345-kV transmission line projects associated with the Competitive Renewable Energy Zone (CREZ) initiative in west Texas. The 345-kV Riley-to-Edith Clarke transmission line is 41.6 miles long and runs from the Vernon area in Wilbarger County to the Crowell area in Foard County. This phase of the ETT CREZ program comprises approximately $141.5 million of ETT’s estimated total CREZ investment of approximately $1.5 billion. The overall CREZ initiative involves eight different transmission service providers, including ETT, constructing 2,400 miles of transmission lines to carry 18,500 MW of west Texas wind generation to eastern load centers in ERCOT. All CREZ projects are scheduled for completion by the end of 2013.


NRG Energy closed on its acquisition of the Gregory cogeneration plant in Corpus Christi, Texas. NRG paid about $244 million in cash for the plant, excluding working capital adjustments. The cogeneration plant provides steam, processed water, and a small percentage of its electrical generation to the Corpus Christi Sherwin Alumina plant, leaving the majority of the base-load generation available for sale in ERCOT. The current operator, DPS Gregory, will continue to operate the plant until NRG operators take over. NRG acquired the plant from a consortium of Atlantic Power, John Hancock Life Insurance, and Rockland Capital.

Three commercial nuclear power plants operated by the Constellation Energy Nuclear Group (CENG) are expected to be operationally integrated into the Exelon Generation nuclear fleet over the next nine months. The plants include the R.E. Ginna plant in Ontario, N.Y., Nine Mile Point station in Scriba, N.Y., and the Calvert Cliffs plant in Lusby, Md. Under the terms of the agreement, the CENG plant operating licenses will be transferred to Exelon; Exelon will integrate the CENG fleet into its management organization; Exelon will lend $400 million to CENG to support a special dividend to Électricité de France (EdF); and EdF will retain an option to sell its CENG stake to Exelon at fair market value between 2016 and 2022. CENG will remain a legal entity governed by a board of directors comprising five EdF and five Exelon board members. Exelon will continue to own 50.01 percent of CENG, and EdF 49.99 percent. The companies filed an application with NRC to transfer the operating licenses from CENG to Exelon. Review and approval is expected to take six to nine months. 

ABB energized the East West Interconnector, a 500-MW high voltage DC-light underwater transmission line connecting EirGrid in Ireland to the U.K. and European grid.

EdF Renewable Energy entered a membership interest purchase agreement with Lincoln Renewable Energy to acquire the first, 200-MW phase of the up-to 500-MW Hereford wind project in Texas, with an option to acquire the second phase of the project. Construction is expected to commence on the first phase later this year in order to qualify for federal tax credits. The project, covering approximately 15,000 acres in Deaf Smith County southeast of the town of Hereford, will connect with CREZ (Competitive Renewable Energy Zone) transmission lines to bring wind generation from the Texas Panhandle to load centers across the state. EdF Renewable Energy is negotiating to secure a long-term, fixed-price hedge agreement for the expected output of the first phase of the project.  

ABB completed its previously announced acquisition of Power-One, a provider of renewable energy and power conversion and management systems. ABB says the Power-One portfolio of technologies complements ABB’s business. Power-One employs almost 3,500 people, mainly in China, Italy, the United States, and Slovakia. 

Mainstream Renewable Power closed a deal to sell its 7.65-MW Carrickeeny wind farm to IKEA Ireland. The project, located in Leitrim in the northwestern part of Ireland, is now under construction. Startup is expected in early 2014, at which point IKEA will purchase the plant. As part of the deal Mainstream will continue operating and maintaining the wind farm on behalf of IKEA for its 20-year lifespan. The acquisition will increase to 137 the total number of wind turbines that the IKEA Group has committed to owning and operating.

In conjunction with Arqiva, Sensus will provide the long-range radio technology for a private communications network.


Siemens received an order for two power plant blocks for the Liberty combined-cycle power project in Pennsylvania, owned by Panda Power Funds. Siemens is expected to deliver two H-class gas turbines, two heat recovery steam generators, two steam turbines, and two generators, as well as the electrical equipment and control system. Panda’s engineering, procurement, and construction contractor is Gemma Power Systems. The order includes a long-term service agreement and has a total value for Siemens of approximately $400 million. 

Panda Power Funds also plans to build, own, and operate an 859-MW combined-cycle power plant in Brandywine, Md. Panda says the Mattawoman plant will be a zero-liquid-discharge plant, returning no waste water to a treatment facility, subsequently preventing discharge into the Chesapeake Bay. Construction will take approximately 30 months from the completion of financing, regulatory approvals, and other conditions.

Calpine began commercial operations at its Russell City and Los Esteros Critical Energy gas-fired combined-cycle power plants, both located in the San Francisco Bay area.
