Savings guarantee

An independently commended verification service

Savings guaranteeSavings from all Powerstar systems are 100% guaranteed.
A thorough and independently commended analysis (based upon IPMVP)  is carried out internally via the steps below to provide clients with an accurate verification of savings achieved:

  • Step 1 – Compares 28 days pre install kWh data against 28 days post install kWh data
  • Step 2 – Compares 28 days post install kWh data against the same dates a year previously (pre install)
  • Step 3 – Compares 84 days (12 weeks) post install kWh data against the same dates a year previous (pre install)
  • Step 4Involves a regression analysis. An accurate model is created based upon pre install
    kWh consumption data and variables such a temperature
  • Step 5 – A verification providing a snapshot of the savings achieved from the negative
    power (back EMF) generated through the patented Powerstar design

100% savings guarantee

Following the analysis, if savings achieved are less than stated in the proposal, the shortfall in terms of £ based on p/ kWh used in the proposal will be calculated.

This figure is multiplied by the payback period as stated in the proposal and issued as a one-off payment.

The graphs below shows the reduced energy consumption in daily CO2 emissions from pre and post Powerstar installation and the kWh consumption pre and post Powerstar install. These graphs were taken from our Newburgh Precision case study, click here to read more.

EXAMPLE

Proposal states 10% saving worth £15,000 pa giving a payback of 2.8 years.

Actual energy savings achieved = 8% worth £12,000

Shortfall = £3,000

We issue a 1 x off payment to the client of £3,000 x 2.8 = £8,400 so the return on investment  is therefore guaranteed.
