After commissioning my A.E.S built power van with a installed power vault all of my hydro usage problems were put to rest. Even after a 20% HP increase on my plant my consumption of power was immediately down 55% from the previous year. As an added bonus to the hydro savings my electrical downtime on the whole package has also saved an astronomical amount. A.E.S is a small company with big results. They understand the needs of their customers and always get the job done.
