Genesis Energy’s FY27 first quarter brought two tangible milestones for its growth plan: the first Huntly battery is commissioned and Leeston Solar Farm has reached final investment decision. The quarter also showed how favourable hydro conditions are reshaping generation, gas use and wholesale-market exposure.
- 100 MW / 200 MWh Huntly BESS Stage 1 commissioned
- Leeston Solar Farm reaches final investment decision
- Thermal generation falls 620 GWh year-on-year to 163 GWh
- Customer base rises 0.7% from June to 493,450
- 11.4 PJ of third-party gas contracted through 2029
Genesis Energy Limited (NZX:GNE, ASX:GNE) has moved two of its most visible growth projects from promise to execution, commissioning the first stage of its Huntly battery and approving Leeston Solar Farm for construction. The milestones arrived in a quarter when strong national hydro storage allowed Genesis to keep thermal generation low, buy more electricity from the market and redirect available gas to industrial customers.
Huntly battery reaches commercial operation
Huntly BESS Stage 1 is now commissioned and commercial, adding 100 MW of power and 200 MWh of storage to Genesis’s portfolio. Design and procurement for Stage 2 are under way, with construction expected to begin in the second quarter of FY27. Stage 2 has a stated project cost of NZ$106 million and the same 100 MW / 200 MWh configuration.
The battery is the latest step in a pipeline that Genesis has been building around firming capacity and renewable generation. Its [link] is not permitted, so no external link is included.
Leeston decision adds another solar project
Leeston Solar Farm has reached final investment decision, with construction expected to start in the second or third quarter of FY27. The 70 MWp project carries estimated total capex of NZ$122 million. It joins Tihori Solar Farm, formerly known as Edgecumbe, which is under construction, on budget and targeting commercial operation in the first quarter of FY28. Rangiriri remains in its pre-FID phase, with a decision expected in the fourth quarter of FY27 or first quarter of FY28.
That pipeline builds on Genesis’s [link] covered in August, when the company reported a NZ$400 million equity raise supporting its renewable and battery expansion. The current report does not provide a new capital-raising figure or an updated total funding requirement.
Hydro conditions suppress thermal output
Thermal generation fell to 163 GWh in Q1 FY27, down 620 GWh from the prior corresponding period, while hydro generation reached 785 GWh. Huntly Unit 5 remained idled, and Rankine units were fuelled with coal for 23% of output compared with 88% a year earlier. Generation emissions fell 70.3% to 130 kilotonnes of CO2, according to the unaudited operating metrics.
The commercial benefit of that flexibility is visible in the trading mix: Genesis bought 1,891 GWh for retail customers at an average NZ$65/MWh, compared with NZ$141/MWh a year earlier. Wholesale electricity sales dropped to 980 GWh from 1,695 GWh, however, and the company cautioned that prices, volumes and financials remain unaudited. Retail electricity sales also fell 108 GWh to 1,766 GWh, even as electricity netback increased 1.4% to NZ$184/MWh.
Gas contracts preserve portfolio flexibility
Genesis has contracted 11.4 petajoules of third-party gas for delivery from March 2027 to December 2029 and exercised its Kupe right of first refusal, securing up to a further 8.6 PJ from January 2027 to December 2028. It has also sold about 0.9 PJ to a third party for delivery in January and February 2027, supporting the extension of Unit 5’s planned shutdown to mid-February.
The customer base rose 0.7% from 30 June to 493,450, with LPG connections adding 1,622 during the quarter. Yet total customers remained 1.9% below the prior-year level and electricity sales were lower, illustrating the tension in Genesis’s stated strategy: improve margin quality while rebuilding growth. The company says its digital investment programme remains within the NZ$145 million envelope, with further residential and commercial migrations scheduled under Releases 2 and 3.
Bottom Line?
The next test is whether commissioned storage, committed solar and secured gas can translate portfolio flexibility into durable earnings once hydro conditions are less forgiving.
Questions in the middle?
- How will Huntly BESS Stage 1 perform through periods of tighter supply and higher wholesale prices?
- Can Leeston and Tihori remain on schedule and within their stated capital budgets as construction advances?
- When will customer growth and higher netbacks begin to offset lower retail electricity volumes?
