The one-day-in-10-years criterion might have lost its usefulness in today’s energy markets. The criterion is highly conservative when used in calculating reserve margins for reliability. Can the...
systems. The Argentina plants are scheduled to achieve commercial operation in the fall of 2014. In Brasil, Eletrobrás subsidiary Amazonas Distribuidora de Energia awarded a contract to Siemens to supply the power island for the UTE Mauá 3 project in Manaus, the capital of the state of Amazonas. Contractor Construtora Andrade Gutierrez is building the plant in two phases—a simple-cycle phase in 2014, supporting the increased electricity demand during the 2014 FIFA World Cup Soccer games, and later a combined-cycle expansion, bringing total capacity to 580 MW. The Siemens contract in Brazil is valued at about $220 million, including gas turbines, steam turbine, three generators, and instrumentation and control systems.
The Pennsylvania Department of Environmental Protection (DEP) issued an air quality plan approval to Moxie Liberty of Vienna, Va., to build a 936-MW power plant in Asylum Township, Bradford County, Pa. The project includes two 468-MW power blocks, both equipped with air-cooled condensers.
Kaua’i Island Utility Cooperative (KIUC) hired SolarCity to build a $40 million, 12-MW photovoltaic power project on 67 acres KIUC is leasing from Līhu’e-based Grove Farm Co. near Koloa. The project will be the third utility-scale solar facility under construction or in development on Kaua’i. When completed, the three projects are expected to meet about 50 percent of Kaua’i’s daytime electrical demand—the highest percentage of solar PV on any U.S. utility’s system.
Georgia Power began operating the third and final unit at the 840-MW gas-fired, combined-cycle Plant McDonough-Atkinson in Smyrna, Ga. Georgia Power started up the first unit at McDonough-Atkinson in December 2011, and the second in April 2012. Georgia Power retired the two coal units at McDonough-Atkinson in September 2011 and February 2012. Removal of the site’s historic stack has begun, with completion expected by June 2013.
Progress Energy Florida will use Comverge’s IntelliSOURCE demand response management system (DRMS) to migrate its EnergyWise Home residential demand-side management program from a one-way to two-way communication system. The system will centrally control more than 500,000 energy management devices from multiple manufacturers being deployed throughout Florida. Progress also will use IntelliSOURCE to automate and manage the workflow required to install the devices.
Siemens introduced version 2.0 of its DRMS. The new system targets demand reductions via substation, feeder, zip code, or geographical location, to allow utilities to reduce power loads at critical sections of their distribution networks. Siemens says the system allows utilities to condition load to meet system needs, “surgically curtailing specific loads within tailored demand response events” to achieve operational or market objectives.
Pepco Holdings launched a customer engagement program with Opower for residential customers in Maryland. The program is designed to help Pepco customers better assess their energy consumption and explore ways to reduce their energy use and monthly energy bills. The program is being trialed with 50,000 residential customers in Maryland, and might be expanded next year.
Entergy Mississippi filed a request at the Mississippi Public Service Commission and the Federal Energy Regulatory Commission for its plan to spin off its Mississippi electric transmission business and merge it into a subsidiary of ITC Holdings and
