Temporal Power Ltd.

Description:

Fast changes in power output from a wind farm can add megawatts of power in a matter of seconds and induce significant voltage spikes and sags. These rapid fluctuations lead to challenges in regulating voltage and power quality on distribution lines. Temporal Power Ltd. and Hydro One Networks are working to demonstrate how an innovative Canadian flywheel electricity storage technology can improve the way wind power is connected to the electricity grid. The flywheel based storage solution developed by Temporal Power will be located on the Hydro One distribution network to mitigate challenges caused by the intermittent output of power from wind farms and to support the grid during faults. Temporal will use a novel low loss flywheel generator combination to deliver a 500kW power rating per unit in an array of up to 10 flywheels (i.e., +/- 5 MW) that has the capacity to absorb real power for up to six minutes, and release it back to the Hydro One distribution network for the same duration. The demonstration represents one of the world’s largest wind integration projects utilizing flywheel storage technology. Temporal Powers flywheel storage technology is expected to significantly reduce GHG emissions in Canada and in the rest of the world by 2020 by enabling further renewable projects.
