The world's first commercial-scale tidal power turbine has delivered electricity into the British grid for the first time in preparation for full-scale operation, Marine Current Turbines announced yesterday. "SeaGen is the world's first commercial-scale tidal stream generating system by a large margin. It is more than four times as powerful as the world's second most powerful tidal current system, which is our own 300kW SeaFlow, installed off Lynmouth on the north Devon coast more than five years ago." Secretary of State for Energy, John Hutton said: "This kind of world first technology and innovation is key to helping the UK reduce its dependency on fossil fuels and secure its future energy supplies" Marine Current Turbines' next project, announced in February 2008, is a joint initiative with npower renewables to take forward a 10.5MW project using several SeaGen devices off the coast of Anglesey, north Wales. It is hoped the tidal farm will be commissioned in 2011 or 2012. The company is also investigating the potential for tidal energy schemes in other parts of the UK, and in North America.

The idea is to create a common set of communication protocols and data formats that utilities and smart-grid start-ups can adhere to.

Part of the growing trend for nearly every electronic device to be able to communicate with others, smart grid and advanced metering startup Trilliant has taken $40 million in its first official venture funding.\n\nTrilliant, like competitors Ambient, Silver Spring Networks, SmartSynch and others, makes wireless communication devices for utility meters. When enough are present in an area, they can form a mesh network capable of communicating moment-to-moment use information back to utilities, and to the homes and businesses they're installed within. (Some can also communicate via hardwired connections.)\n\nThe company is one of the oldest to try to tackle the problem. I covered it in more depth in June. The problem with looking at the field is that, at first glance, all the contenders seem to be pretty much identical; broadly speaking, each is approaching the same problem, that of trying to get more information about usage to consumers and utilities, in more or less the same way.

The London Stock Exchange listed Indian company, Vedanta, will build a US$15M (Dh55M) continuous copper rod plant with annual capacity of 100,000 tonnes in Fujairah, UAE, which will be operational by December to capture the strong demand from regional infrastructure projects. Copper rods manufactured by the plant will be used in cables for power grids for the region and the company is expecting more demand coming from not only the UAE and the GCC but the whole Middle East.

Switzerland-based power and automation technology group, ABB Ltd., won a contract tendered by TenneT, the Dutch-German transmission grid operator, to connect North Sea wind farms to the German mainland grid. The order is worth US$1.0B and ABB expect to use over 135km of 320kV submarine cable in the designed transmission system. The project is expected to be operational in 2015 and follows two other offshore wind connection orders for ABB in Germany; the 800MW Dolwin1 link awarded last year and previously, the BorWin1 project. The Dolwin1 link is expected to be completed in 2013 and will involve the use of 150km of 320kV copper submarine cable.

Industry sources expect China to invest RMB300B by 2011 for the construction of power grids. The project, which will consist of ultra high voltage, 200-750kV and 110kV or lower sections, is anticipated to require between 1.12 and 1.25Mt of copper.
