Substations are one of the most vital parts of our electricity infrastructure. Substations serve to reduce the high voltage electricity from transmission lines to the lower voltage electricity required by the distribution lines. These distribution lines bring power to our homes and businesses. The transmission lines run at high voltage to ensure electricity is moved across the island in the most efficient way possible, while local buildings require lower voltage to operate appliances and electric devices more safely.
The electricity grid is a complex network of energy generators, transmission lines, transformers, storage devices and substations that all work together to move electricity from its production site to the nearest outlet almost instantly. Next time you plug in your favorite device, pause and think about how many different steps it takes to get electricity from the sun or a generator to you!
