- Mass market electricity and gas sales up 21% year-on-year
- Contracted wholesale electricity sales increased to 1,056GWh
- Unit generation cost dropped to $38.16/MWh from $54.27/MWh
- South and North Island hydro storage well above average
- Renewable projects under construction with $1.5 billion committed
Surge in Sales and Slashed Generation Costs
Contact Energy (NZX:CEN) posted a notable uptick in mass market electricity and gas sales for June 2026, reaching 495GWh; up 21% from 410GWh in June 2025. This growth extended to contracted wholesale electricity sales, which climbed to 1,056GWh from 810GWh a year earlier. Meanwhile, the company achieved a significant reduction in unit generation costs, falling to $38.16/MWh from $54.27/MWh in June 2025. Own generation costs also halved to $26.28/MWh, reflecting improved operational efficiencies.
Hydro Storage Remains Strong Amid Record Warm June
Hydro storage levels remain robust, with South Island controlled storage at 145% of mean and North Island at 123% as of mid-July 2026. Contact’s Clutha scheme storage also sits well above average at 147%. These elevated water inflows, notably 171% of mean in June, come during New Zealand’s warmest June on record, with average temperatures 1.9°C above the 1991-2020 norm. Despite this, total national electricity demand was flat compared to June 2025, suggesting weather-driven consumption patterns are evolving.
Renewable Projects Drive Capital Commitment
Contact continues to invest heavily in renewable energy infrastructure, with $1.5 billion committed across four major projects under construction. These include the $273 million Kōwhai Park Solar and $712 million Te Mihi Stage 2 geothermal projects, alongside the Glenbrook-Ohurua Battery 2 and Glorit Solar developments. The solar projects are being delivered through a 50/50 joint venture with Lightsource bp, highlighting Contact’s strategic partnerships in expanding its clean energy portfolio.
Environmental and Social Governance Progress
On the ESG front, Contact reported a substantial reduction in greenhouse gas emissions from generation assets, dropping from 190kt CO2-e in Q4 FY25 to 64kt CO2-e in Q4 FY26. The company also increased native tree plantings to 38,085, more than doubling the previous year’s figure. Water usage metrics show a decrease in freshwater take and a rise in non-consumptive water use, reflecting sustainable operational practices. Gender diversity remains a focus, with women comprising 29% of the board and 22% of key management personnel.
Integration Costs and Market Pricing Trends
Contact disclosed $26 million in costs related to its Manawa acquisition, including $13.6 million in transaction expenses and $12.4 million in integration costs. These charges are partly reflected in operating costs but are not expected to materially affect underlying performance. Meanwhile, wholesale electricity futures prices for the fourth quarter of 2026 have declined sharply, with the Otahuhu settlement price falling from $77.5/MWh in late May to $45.55/MWh by mid-July, a trend that may pressure future margins.
Bottom Line?
Contact Energy’s improved cost structure and strong hydro reserves position it well, but declining futures prices and integration expenses warrant close monitoring.
Questions in the middle?
- How will falling wholesale futures prices impact Contact’s profitability in coming quarters?
- Can the company maintain generation cost efficiencies as renewable projects ramp up?
- What is the timeline and expected impact of the Manawa integration on operational performance?
