Alstom unveils worlds first high-voltage equipment designed

SF 6 is a potent greenhouse gas commonly used as an electrical insulator. In August 2014, Alstom became the first company in the world to offer the electrical industry a technically and economically viable alternative toSF 6. The first application is a pilot project for a 420 kV g 3 -insulated busbar 1.

PowerGrid SolutionsHealthcareAviationSkills DevelopmentNigeria, Africa’s largest power privatization market reflects what’s possible through a determined effort to bring private sector participation in the power sector. The privatization strategy appears to be working in Nigeria after the government successfully sold 5 power generation and 11 distribution companies in 2014. The ongoing reforms in Africa’s largest economy also usher in Greenfield projects. GE is working closely with the new owners of privatized assets to ramp up power production. Independent Power projects in Nigeria that GE is currently working with include Ogorode, Benin, Omotosho, Olorunsogo and Alaoji Power Plants – all with a combined GE-enabled installed capacity of over 4000MW. These milestones are in fulfilment of the MOU GE signed with the Federal Government, committing to help generate additional 10,000 megawatts of electricity for Nigeria over ten years.

It was just two years ago that GE announced a breakthrough in developing a substitute for insulating gas in gas-insulated equipment. Such a substitute had become necessary because gaz sf6, despite its undeniable qualities—its arc-quenching and dielectric capabilities—has a global warming potential (GWP) 23,500 times that of CO2, with a lifetime in the atmosphere of over 3,000 years.
