Sales Volumes Climb as Customer Demand Strengthens

Contact Energy (ASX:CEN) recorded a notable 27% increase in combined mass market electricity and gas sales for July 2026 compared to the same month last year, rising to 579GWh from 456GWh. Electricity sales alone reached 403GWh, while gas sales doubled to 177GWh. Despite this volume growth, customer netback prices held steady at around $147/MWh, slightly below July 2025’s $148.69/MWh, reflecting stable pricing conditions amid rising demand.

Generation Costs Fall Sharply as Output Expands

The wholesale segment also showed strength with contracted electricity sales climbing to 1,079GWh, up from 987GWh a year earlier. Total electricity generated or acquired rose 12% to 1,168GWh. Notably, unit generation costs, which include acquired generation, fell significantly to $36.99/MWh from $47.40/MWh in July 2025. Own generation costs also dropped to $27.11/MWh, indicating improved operational efficiency and cost management.

Hydro Storage Remains Robust, Supporting Market Supply

Hydro storage levels remain comfortably above average in key regions, with South Island controlled storage at 137% of mean and North Island at 85% as of 11 August 2026. The Clutha scheme storage stands at 109% of mean, supported by inflows at 132% of mean for July. These strong water reserves underpin generation capacity and provide a buffer against potential supply volatility during winter months.

Renewable Projects Progress with Significant Capital Investment

Contact continues to invest heavily in renewable energy infrastructure. Four major projects are underway: the Kōwhai Park Solar and Glorit Solar farms, delivered in partnership with Lightsource bp, and the Te Mihi Stage 2 geothermal and Glenbrook-Ohurua Battery 2 projects. Combined, these developments carry approved costs exceeding NZD 1.5 billion, with staggered online dates from late 2026 through early 2028, reinforcing Contact’s commitment to expanding its low-carbon generation portfolio.

Wholesale Prices Surge Ahead of Winter

Wholesale electricity futures prices for the Otahuhu node have risen sharply for the fourth quarter of 2026, climbing from $62.60/MWh at the end of June to $73/MWh by mid-August. This increase reflects tightening market conditions and higher demand expectations heading into winter. The rise in futures prices contrasts with a relatively stable net revenue per MWh of $179.17 recorded in July, slightly above last year’s $178.62.

Environmental Metrics Show Progress on Emissions and Biodiversity

Contact’s latest ESG data for Q4 FY26 indicates a substantial reduction in greenhouse gas emissions intensity from generation assets, down to 0.023 kt CO2-e per GWh from 0.081 in the previous year. Freshwater usage has declined, while native tree planting efforts more than doubled to over 38,000 trees. These gains complement Contact’s broader sustainability goals, including its net zero emissions target by 2035.

Bottom Line?

Contact Energy’s July performance suggests a solid operational footing with rising sales, lower costs, and strong hydro reserves, setting the stage for its renewable expansion amid evolving market prices.

Questions in the middle?

  • How will rising wholesale futures prices impact Contact’s margins in the coming quarters?
  • What progress can investors expect on the commissioning of key renewable projects in 2026-2028?
  • Will sustained hydro storage levels continue to support generation costs through winter?
