Portland College is a vibrant national college for people with disabilities and associated learning difficulties.
Portland College strive to develop every learner’s unimagined potential with a personalised programme that can include work experience and volunteering.
Environmental issues are particularly important to Portland College, and they take it upon themselves to be as environmentally friendly as possible.
Portland College implement, teach and recognise the importance of minimising their impact on the environment and actively seek to reduce carbon emissions through implementing energy efficient technologies and encouraging best practice in sustainability.
Portland College actively sought a transparent technology that would effectively reduce their carbon footprint, reduce their electricity costs and would do so efficiently, whilst also ensuring security and reliability.
Voltage optimisation was identified as a technology that fit this criteria.
Through a transparent enquiry process and a thorough evaluation and analysis procedure, the Powerstar team were able to reassure Portland College that the UK manufactured Powerstar voltage optimisation system was the ideal solution for their site.
Powerstar were able to demonstrate their capability within the education sector through previous installation reference points and the engineering focused, project led approach gave Portland College the confidence that the Powerstar team would implement the right engineering solution to provide maximum electricity savings and carbon reductions for their site.
