Isle of Wight College


Established in 1951, the Isle of Wight College offers training opportunities across a broad curriculum. From higher education and apprenticeships through to employer training and vocational courses, this further education college reflects the needs of the local community. In recent years the Isle of Wight College has invested millions in growing campus facilities.

The Problem

Salix Finance Ltd. provides interest-free government funding to the public sector, which includes further education colleges, to improve their energy efficiency, reduce carbon emissions and lower energy bills. Salix has a conservative approach to estimating savings from voltage management technology and the payback for a project needs to be under 5 years to secure funding.

Our Solution

Salix has delivered over 14,000 energy projects and over £116 million of savings per annum. The Isle of Wight College utilised this funding and installed two powerPerfector voltage optimisation units in 2012 as part of a voltage management project. The third install of a powerPerfector Plus was more complex than the previous two, with a survey being undertaken before the unit was manoeuvred up 15 steps before being built in situ. A success which was made possible with careful planning, coordination between iESCo and the college and a trusted installation team. All three units were installed by iESCo approved contractors.

The Results

Whilst the reduction in electricity consumption across the two existing powerPerfector units was originally predicted at 8.5%, records of actual consumption show that they achieved savings of 11% (Sixth Form & LRC) and 17% (J Block). This helped to quicken the payback making the 0% interest repayments much lower than the savings achieved.

The Overview

  • 11-17% Energy Savings

“The performance of the three powerPerfector optimisers at the College has far exceeded all expectations. Our optimisers give savings of 17%, 11% and 11% across our three electricity meters – evidenced by data.”

Philip J Smith, Estates Manager, Isle of Wight College.
