Keble College - case study on electricity usage

Keble College is one of the largest of the constituent colleges of the University of Oxford with 410 undergraduate and 235 graduate students. It was the wish of the founders in 1870 to extend access to the University more widely, and the College has a continuing commitment to inclusiveness.

After Keble College sent its annual electricity consumption details, it was possible to give a provisional quote for a powerPerfector unit and the energy savings that would be expected.

powerPerfector is an EAUC Silver Company Member.

A voltage logger was then sent for one week, which recorded the voltage level in the building by connecting it into a regular mains socket. It was found that the average voltage at the site was 245 volts (V), 15V higher than the nominal supply in the UK. After a survey of the site by a powerPerfector Approved Contractor, the installation took place.
