Engineering, procurement and construction (EPC) contracts are evolving as utilities seek to spread risks, contain costs, and execute their business strategies. As a result, turnkey contractors are...
supervisory control and data acquisition (SCADA) and distribution automation system to monitor and control two electrical systems in Cuming County Public Power District and Stanton County Public Power District. The public power utilities expect the system to reduce outages, improve grid reliability, and save energy and costs. ABB is providing SCADA software, a communication gateway for substations, wireless sensors and other distribution technologies, as well as project oversight. ABB is subcontracting on this project with RuggedCom to deploy a wireless-enabled communications infrastructure.
Siemens is implementing coordination of two New York State sites, Rochester Gas & Electric (RGE) and New York State Electric & Gas (NYSEG) , into a single system with the Spectrum Power energy management system (EMS). The client is Iberdrola, parent company of NYSEG and RGE. The project is scheduled to ship and install in 2013. The NYSEG and RGE models will be combined into a single network model as part of the project. Spectrum Power is a message-based SCADA platform, with application functionality (such as network analysis and historical archiving) provided by separate components.
EVs & Storage
Progress Energy Carolinas provided 150 residential customers with plug-in electric vehicle (PEV) charging equipment as part of a new research project to help Progress Energy better understand the impact of PEVs on the electric utility system. The program is funded through an ARRA smart grid grant from the U.S. Department of Energy. The grant will cover up to $1,500 of the equipment and construction costs of installing a Level 2 charging station at a customer’s home. Progress Energy Carolinas will own and maintain the charging equipment for the duration of the research project, which is expected to end in April 2013.
EnerSys launched a joint venture in Germany to produce large format lithium-ion battery cells. EnerSys will have a majority interest in the joint venture in cooperation with GAIA Akkumulatorenwerke (GAIA), a wholly owned subsidiary of Lithium Technology Corp. (LTC). LTC is bringing intellectual property and lithium-ion manufacturing capabilities located in Nordhausen, Germany. The joint venture will expand an existing distribution agreement between the two companies. The new joint venture company expects to develop and produce lithium-ion based battery systems for space, naval, marine, renewable energy and specialty high power applications for EnerSys, and will provide certain products to LTC for customers in the transportation sector.
AEP Ohio began installing a PureWave community energy storage (CES) system from S&C Electric . AEP says the lithium-ion-based CES system is the first of its kind to be installed at customer homes, providing up to several hours of backup power during a power outage for customers who are connected to the CES unit. Sensing technology present in each CES unit recognizes when a home served by that unit loses electric power. When a power outage occurs, the CES battery automatically begins providing power to the home via a transfer process that should occur without any impact on electric power quality. When AEP Ohio restores power to the affected homes, customers are transferred from the battery unit back to the electric grid. S&C’s IntelliTeam distributed energy management
