Islands & Isolated Grids
Isolated grids such as islands, remote communities and remote industrial operations are typically cut off from larger grid infrastructure and therefore face unique challenges. They are often dependent on expensive liquid fossil-fueled generators for electricity supply. Renewable energy—such as wind and solar—introduces a path to escape from this expensive fossil fueled generation, but at a cost to grid stability. These grids are typically smaller and less diverse than major market grids, and stability cannot always be efficiently managed with generation alone—sometimes actions involve disconnecting loads. Beacon flywheel storage systems offer a grid stabilizing solution that provides frequency control and voltage support through active and reactive power injection and absorption. Flywheel storage increases the proportion of variable wind and solar that can be integrated, thus reducing fossil fuel consumption and associated cost as well as generation unit starts and stops and ramping related wear and tear.
