Highlights

  • Meridian Energy (MEZ) reports lowest early-year inflows on record.
  • Hydro storage declines, impacting power generation.
  • Weather conditions contribute to lower sales and output.

Meridian Energy (ASX:MEZ) has released its February 2025 operating report, revealing a tough start to the year due to record-low hydro inflows and declining storage levels. The company reported inflows at just 42% of the historical average, marking the weakest beginning to a calendar year in its recorded history.

Declining Hydro Storage Poses Challenges

Hydro storage levels took a significant hit in February, with national storage dropping from 91% to 76% of the historical average by early March. The South Island’s storage levels stood at 72%, while the North Island’s reservoirs maintained a healthier position at 103%. This decline in hydro storage has put pressure on electricity generation, impacting overall output.

Lower Generation and Retail Sales

Meridian Energy’s electricity generation in February fell by 5.9% compared to the same period in 2024. The dip was attributed to lower hydro and wind generation, influenced by unfavorable weather patterns. Retail sales volumes also saw a decline, slipping 1.9% year-on-year.

Among customer segments, agricultural sales experienced the steepest decline, dropping by 10.1%. This reduction could be linked to dry weather conditions affecting farming operations, leading to lower energy consumption in irrigation and other agricultural activities.

Weather Conditions Play a Key Role

The climate played a crucial role in Meridian Energy’s performance last month. February was marked by warm and dry weather across much of New Zealand, with above-average temperatures and significantly below-normal rainfall in most regions. The lack of sufficient rainfall has put further strain on hydro storage, limiting the company’s ability to generate power at optimal levels.

Looking Ahead

With hydro storage levels lower than usual and inflows remaining weak, the focus will be on how Meridian Energy navigates the coming months. The company’s ability to manage its hydro assets effectively while responding to changing weather conditions will be key in maintaining stable energy production.

As the industry watches these developments, future reports will provide insights into how Meridian Energy adapts to ongoing climate and market challenges.
