Number of customers

This chart shows the actual and predicted number of customers that PowerCor has in the region. The grwoth rate is modest at about 1.5% with a 2030 population of 3185.

Power demand (per annum)

This chart shows the actual and predicted power demand per annum that PowerCor supplies in the region. The growth rate is modest at about 0.35% with a 2030 value of 17.7 Gwh

Note the weird jumping around was COVID

Local rooftop solar generation (per annum)

This chart shows the actual and predicted power solar generation that is exported to the grid per annum. Its important to note this doesn’t include the majority of solar being generated as that’s consumed at the household level and effectively reduces the level of usage. The growth rate is solid at about 24% with a 2030 value of 5 Gwh.

Grid level renewable energy

This chart shows the percentage of grid level that is renewable. This has been published from early 2000’s to 2023. The graph shows a prediction going out until 2030. The growth rate is escalating but in early 2025 is 39%. Its predicted to be around 82% by 2030 inline with government policy.

Closing the gap

This chart brings all the above together to show how renewable generation from local rooftop solar and the grid is eating away at demand. As you can see by 2030 we are still short by a few Gwh per annum.

The road to 100%

To close the gap in the above chart we are proposing that a local solar / battery farm be established. The exact details of the sizing will be determined later but at this stage we believe it will be a 4Mw solar array with a 5Mwh battery.

What this does to close the gap is;

• Provide the missing 2.5 Gwh
• Add extra capacity to cover potential growth in electric vehicles
• Add extra capacity to cover our assumption that the grid solar does not include our own rooftop solar
• Provide storage so that we can shift energy from when its generated to when its used. This helps alleviate the issue that our 100% calculation is net only.
