Contact Energy Faces Market Price Volatility Despite Strong Sales and Hydro Storage

Sales and Margins Accelerate

Contact Energy (NZX:CEN) posted a notable 31% jump in mass market electricity and gas sales for April 2026, hitting 372GWh compared to 284GWh a year earlier. The mass market netback; a key margin metric; also improved to $153.24/MWh, up from $148.59/MWh in April 2025, signalling better profitability from retail operations. This growth in retail volumes and margins builds on the momentum seen in the prior month’s report, which recorded a 27% rise in combined sales, reflecting stronger demand and pricing dynamics in New Zealand’s energy market.

Electricity demand nationally rose 3.6% year-on-year in April, supported by a slightly warmer nationwide average temperature of 14.0ºC, 0.6ºC above the 1991-2020 April average. Regional demand growth varied, with the South Island excluding NZAS up 7% while the North Island saw a more modest 3% rise. These demand shifts are crucial for Contact’s retail and wholesale strategies as it balances supply and pricing.

Wholesale Sales and Cost Efficiency

On the wholesale front, contracted electricity sales surged to 898GWh in April 2026, up from 655GWh a year prior. Total electricity generated or acquired also jumped to 962GWh, a 33% lift from 722GWh in April 2025. Despite this higher output, Contact managed to reduce its unit generation cost to $44.95/MWh, down from $49.48/MWh the previous year. Own generation costs fell even more sharply to $31.60/MWh from $41.60/MWh, underscoring improved operational efficiencies and a shift toward lower-cost renewable generation.

Hydro storage levels remain robust, with South Island controlled storage at 107% of mean and North Island storage at a striking 179% of mean as of mid-May. This surplus water availability supports Contact’s hydroelectric generation capacity and provides a buffer against dry periods. Inflows into Contact’s Clutha catchment were 123% of mean for April, a significant rebound from the 85% recorded in March. These factors contribute to the company’s ability to supply contracted volumes reliably and cost-effectively.

Renewable Projects and Capital Investment

Contact continues to invest heavily in its renewable pipeline, with three major projects under construction. The Kōwhai Park Solar project, a 50/50 joint venture with Lightsource bp, is expected online by Q3 2026 with an approved budget of $273 million. The Te Mihi Stage 2 geothermal expansion, slated for Q3 2027, commands a $712 million investment, while the Glenbrook-Ohurua Battery 2 project aims to come online in Q1 2028 with costs of $235 million. These projects reflect Contact’s strategic commitment to expanding renewable capacity and grid stability amid New Zealand’s energy transition. The scale and timing of these investments align with the company’s broader growth trajectory and market positioning.

Environmental metrics also show positive trends. Contact’s greenhouse gas emissions intensity from generation has fallen sharply, with Q3 FY26 emissions at 0.032 kt CO2-e per GWh, down from 0.136 kt CO2-e in Q3 FY25. Biodiversity efforts have ramped up, with native tree plantings increasing from 352 to 2,430 and pest control activities intensifying. These ESG initiatives complement Contact’s operational focus and may enhance its social licence to operate.

Contact’s recent operational improvements and renewable investments follow a leadership change earlier in 2026, when Jon Macdonald took over as Chair from Rob McDonald, who had overseen the company’s renewable expansion and Manawa Energy acquisition. This governance continuity supports Contact’s strategic execution and market confidence.

Looking ahead, the Otahuhu futures settlement price for Q3 2026 has softened to $141/MWh as of mid-May, down from $189/MWh at the end of March, indicating market price volatility that Contact will need to navigate. Meanwhile, contracted gas volumes for the next 12 months stand at 8.7 PJ, providing fuel supply certainty for thermal generation where needed.
