In the year to 30 September 2025, total electricity connection numbers grew by 1.2%.  However, new connections for the three months ended 30 September 2025 are 7.0% lower than in the three months to 30 September 2024. Electricity distributed volume was up 1.3% compared with the three months ended 30 September 2024, largely correlating with cooler temperatures where more electricity is used for heating. Residential volumes were up 1.6% while business volumes were up 1.0%.

Gas distribution volume for the three months to 30 September 2025 was down 2.7% compared with the prior comparative period, due to lower demand from the residential, industrial and commercial sectors.
 
SAIDI minutes for normal operations (planned) for the six months ended 30 September 2025 is lower than the prior comparative period reflecting our on-going focus on preventive maintenance and vegetation management. SAIDI minutes for normal operations (unplanned) for the six months ended 30 September 2025 is higher than the prior comparative period and includes the impact of Cyclone Tam, which also triggered a Major Network Event beginning on the 15^th of April 2025 and lasting until mid-morning of the 18^th of April. We note that SAIDI results are preliminary and subject to audit.
