The maximum system size permitted by the distribution network operator was 89.25kilowatt-peak, so the system was designed accordingly. The site was ideal for solar power, as refrigerated storage has a high electricity demand, particularly during the summer months, matching perfectly with the peak generation of the solar PV system.

Our client in this case wanted to make their investment decision on an absolute worst-case scenario. All of the modelling for the investment forecasting was based on the assumption that the electricity generated would be sold directly to the grid, essentially for a wholesale price.

In reality, the vast majority of the electricity will be used on site, realising a cost saving far higher than the export sale price. This means that they can be confident of achieving a much faster rate of return on their money.
