November 24, 2009 - STRI20/20/20 Smart Grids for a Green Future
2009 STRI is celebrating our 20 years anniversary in the "High Voltage Valley" of Ludvika. Anyone remembers 1989? When we did not have Internet, no Skype or DVD, no mobile cell phones and the PC had DOS. During these 20 years we have had a fast development within both HV technology and ICT –Information & Communication. Now we are facing an even greater challenge that some call a new industrial revolution. How shall we build a sustainable and "green" society according to the 2020 goals from EU and how will our power system look like 20 years from now? Welcome back to the future! Read more...

January 20, 2009 - STRI performs successful HVDC testing for BHEL and POWERGRID of India
Extensive testing on overhead line insulator strings were performed during November and December 2008 for the Biswanath-Chariyali-Agra 800 kV HVDC project. This transmission line will be more than 2000 km long and increase the power capacity of the Indian transmission system with an additional 6000 MW. By harvesting the huge hydropower resources in the Himalayas the Biswanath-Chariyali-Agra project will give an important contribution to renewable power production in India. Read more
