The SAPN Story
(for Standard Control Services)
• Growth in revenue & Growth in Asset Base (RAB) since 2010 – RAB
growth driven by new asset investment post 2010 (chart 3 & 4)
• Revenue growth has been most rapid in the residential sector (chart
5)
• Operating expenditure (opex) also grown rapidly since 2010.
Corporate Services and Vegetation management opex categories
growing fastest (chart 6);
• Noting growth in employee bonuses parallel growth in revenue
(chart 7)
• Demand declining in all sectors – drive future price increases given
asset base expansion (charts 8 & 9)
• Capital investment in last few years has significantly reduced average
asset life (chart 10)
• Growing spare capacity in the system (chart 11)
• But little change in service quality (chart 12).
