Results – Resizing
Assuming a community installs a renewable system at present, sized to their current demands, and continues to resize the supply whenever significant changes are made to improve the energy efficiency of the homes.
As we can see our averaged match rate over summer and winter is stable for each resized scenario, meaning that if continual resizing takes place, the community can retain the same match rate. This obviously has financial implications of spending money to regularly resize.
The table below shows the final results for each of these scenarios:
From this we can see that as the resizing takes place, the match rate and grid interaction can be kept fairly constant, with the 2050 case 2 values slightly worsening due to the differences in the profile due to behavioural changes. This leads us to the conclusion that in the future in the case where there are no feed-in-tariffs; the demand-supply match could be successfully maintained by resizing. This does invite the question however that if a community is willing to invest initially in renewables, would they be prepared to continually invest to ensure that their system does not cause a great waste in energy production?
