Aiming for a stable grid New technology will be installed at a power site in Keith, Scotland, in a $25 million project to make using renewable energy easier and cleaner. GE Power Conversion’s Rotating Stabilizer machinery will provide stability of supply to the grid without producing harmful carbon emissions. It is designed to remove the need to run fossil-fuel-powered generators to ensure the electricity system remains stable while energy supplied from renewable sources, such as wind and solar, fluctuates.

When, earlier this year, enough renewable energy was generated to supply the grid, 17 coal and gas power stations were turned on to keep it stable. Julian Leslie, head of networks at NGESO said: “The GB electricity system is one of the most advanced in the world, both in terms of reliability and the levels of renewable power, and we’re really excited to be adding to that with this new approach to operating the grid. “This approach is the first of its kind anywhere in the world, and is a huge step forward in our ambition ... to operate the GB electricity system carbon-free by 2025.” Medical wire Sandvik’s Exera ® medical wire is specifically developed to transmit, sense or stimulate signals within the body. Medical devices are implanted close to the nerve that requires stimulation, meaning that metals and coatings used to manufacture the wire must be biocompatible. Also, as with any medical implant, fine medical wire must be lubricious, and malleable enough to be precisely directed in the body so that the right area is targeted for stimulation.

GE Power Conversion will build and install the equipment. Stability services, such as inertia, short circuit level and frequency, have traditionally been provided by using the kinetic energy in the spinning parts of large generators that run on fossil fuels.
