National Grid has energised its 2.5km 275kV power tunnel between Hurst substation and Crayford, one of the transmission circuits in the 32.5km LPT2 route across south London. “The previous cables between Hurst and Crayford were reaching the end of their operational life, having been commissioned in 1967 and having served London reliably for decades,” according to National Grid, which explained: ...
Tesla is developing a battery specifically for grid power storage – following on from it building the world’s largest lithium-ion battery in Australia. Called Megapack it is an assembled containerised 3Wh battery that includes 1.5MW of inverters. “Every Megapack arrives pre-assembled and pre-tested in one enclosure from our Gigafactory, including battery modules, bi-directional inverters, a thermal management system, an AC main ...
Vishay has introduced 8kW mica-insulated resistors in millbank size. Called GREM, the firm is promoting them as a lower cost option to stainless steel grid designs. “8kW at 40°C is 23 % higher than standard 6,500W stainless steel grid resistors in the standard millbank size,” said Vishay. “At the same time, GREM devices are 30 % lighter than stainless steel ...
The Engineering and Physical Sciences Research Council (EPSRC) has released the funding it promised for low-carbon ‘Supergen’ national energy research centres last year. £15m will be shared between the centres, which are to be multi-disciplinary collaborations between universities, academic bodies and industry. Getting £5m each, the three Supergen Energy hubs will be focused on off-shore renewable energy, bio-energy, and energy networks – ...
LED-maker Plessey has added a 2MW ‘behind the meter’ (BTM) battery to its Plymouth fab. The battery power will earn revenue through a frequency response balancing contract with National Grid and help Plessey reduce its energy costs through peak-shaving of power supply in response to fluctuations in demand. Amber Infrastructure Limited provided funding for the project, which was completed by KiWi ...
Second-hand electric car batteries are to be used for static energy storage following a deal between Nissan and Californian commercial energy storage firm Green Charge Networks. Nissan, according to Green Charge, has conducted non-vehicle research using batteries from its Leaf car in Japan, the US and Europe through 4R Energy, its joint-venture with Sumitomo – over 178,000 Leafs have been sold. ...
