The Bolton TRF was looking for viable ways to make substantial energy savings. One of the technologies considered by the onsite engineering team was power optimisation offered by powerdown220. Voltage optimisation and power factor correction offer two different,
but complementary power saving techniques. Voltage optimisation directly reduces the amount of power drawn by the connected equipment by supplying it at a voltage nearer to its design voltage, whereas Power factor is a way of describing how efficiently electrical power is consumed.

The installation of an powerdown220 – MAX combined voltage optimisation and power factor correction unit reduced the total amount of power drawn which translated into additional generator export revenue for the site. Prior to installation a detailed site survey was carried out together with datalogging to obtain base information. The site was then logged again following installation and comparisons made. 

9% average power (kVa) reduction achieved by the ECO-MAX, equating to a financial saving of £212,852 per year, with a project payback of 3.6 months!
