Genesis Energy has begun construction of the 136MWp Tihori Solar Farm in the Bay of Plenty, moving ahead with one of its most important renewable energy developments in New Zealand. Located near Edgecumbe, the project represents a major capital commitment and forms a central part of the company’s wider plan to expand its solar generation portfolio across the country.

The start of on-site work was marked by a sod-turning ceremony, formally launching construction on the 209-hectare development. The project name, Tihori, was gifted by the Rangitaiki Hapu Coalition, giving the development a local identity that connects the project to its regional setting and community context.

Scale, Output and Operational Timeline

Once completed, the solar farm is expected to begin operating in mid-2027 and generate around 238GWh of electricity each year. At that level of output, the project will add meaningful renewable generation capacity to New Zealand’s electricity system at a time when the market is focused on strengthening supply, improving flexibility, and reducing reliance on fossil fuel generation.

The facility will use roughly 220,000 solar modules installed on a horizontal single-axis tracking system. This design allows the panels to follow the sun through the day, improving generation efficiency across changing daylight conditions. The technology is also notable for its relatively low operating noise and limited water use, which supports the project’s environmental performance profile.

Genesis has indicated that the mounting structures are being designed to withstand potential flooding while maintaining a relatively low impact on the land. The project is expected to operate for at least 35 years, pointing to a long asset life and a sustained contribution to the country’s renewable energy supply.

Execution Structure and Infrastructure Connections

The construction start follows Genesis Energy’s final investment decision on the project, announced after key enabling steps were completed, including grid connection approval and the appointment of Metlen as the engineering, procurement and construction contractor. Horizon Networks has been selected to design and build the overhead grid connection line that will link the solar farm to the existing Transpower Edgecumbe substation.

That transmission link is a critical part of the project’s value, as utility-scale renewable assets depend not only on installed capacity but on efficient integration into the wider electricity system. By connecting to existing grid infrastructure near Edgecumbe, the project is positioned to deliver electricity into the network with established transmission access.

The solar farm itself is being developed on private land about 2.5 kilometres northeast of Edgecumbe. Its location and connection design reflect the increasing importance of site selection, land suitability, and network access in the economics of large-scale solar development.

Role in Genesis’s Broader Energy Strategy

The Tihori project is not a standalone investment. It sits within a broader NZ$1.1 billion company strategy aligned with New Zealand’s renewable energy direction and Genesis’s long-term portfolio repositioning. The company has set a goal of building 500MWp of solar capacity nationwide, and Tihori is one of the core projects helping move that target toward delivery.

Genesis is also linking solar development with its wider generation and storage strategy. The company has said the project will complement the value of its hydro generation portfolio and battery storage investments, helping create a more flexible renewable system. That is strategically important because solar generation can strengthen supply diversity, while hydro and storage assets can help manage variability and support balancing needs across the grid.

The company also expects the project to contribute to reducing gas-fired generation over time. That matters in the New Zealand context, where the transition toward a more renewable electricity mix increasingly depends on how effectively new intermittent generation is paired with flexible assets and network capacity.

Regional Economic Impact and Development Momentum

During the development phase, the project is expected to create more than 100 construction jobs, along with several permanent positions once the site becomes operational. Genesis has also encouraged the participation of local subcontractors and suppliers, indicating that the project is intended to deliver regional economic benefits alongside electricity generation.

This local impact is relevant because large renewable infrastructure projects are increasingly assessed not only on generation capacity, but also on how they contribute to employment, contracting opportunities, and broader community value creation. In regional markets, those factors can shape both stakeholder support and the long-term social licence of infrastructure development.

Genesis’s expanding presence in solar also points to a larger market shift. The company now has around 700MWp of solar capacity in its project pipeline, underlining its emergence as one of New Zealand’s more active solar developers. It previously opened the 63MWp Lauriston solar facility in April 2024 through a joint venture with FRV Australia. Although Genesis and FRV Australia ended that development partnership in October 2025, Genesis has continued to expand independently, including through the acquisition of the 247MWp Waikato solar project, which is expected to come online in 2029 and is planned to include energy storage.

Outlook for New Zealand’s Renewable Capacity Expansion

The start of construction at Tihori reflects a broader structural trend in New Zealand’s power market, where utility-scale solar is beginning to take a more material role in future supply planning. For Genesis, the project is both a generation asset and a portfolio strategy decision. It adds scale, supports diversification, and strengthens the company’s position in an electricity market where renewable flexibility is becoming increasingly valuable.

If delivered on schedule, Tihori will stand as a major addition to the country’s solar capacity and a practical example of how renewable generation, transmission planning, storage strategy, and regional economic development are becoming more closely linked in the next phase of New Zealand’s energy transition.
