Status Proposed

The specification of eight turbines for a 35 MW total capacity implies an average rated capacity per unit, though specific per-turbine megawatt ratings are not explicitly detailed in the primary source material beyond the aggregate total. The 210 m height places these turbines among the taller structures in the Southland landscape, which is relevant for visual impact assessments and aviation considerations. The 160 m rotor diameter provides a substantial swept area, which is a key determinant of annual energy production for each unit. The project's technical parameters reflect a design choice to utilize fewer, larger units rather than a higher count of smaller turbines, which can influence land use patterns and grid connection requirements in the Blackmount area.

Site Location and Environmental Context

The Jericho Wind Farm is geographically situated in the Southland region of New Zealand, specifically located near the settlement of Blackmount. This positioning places the proposed development within a distinct topographical and climatic corridor. The site is described as being approximately 25 km south of Manapouri and roughly 50 km north of Tuatapere. These distances establish the farm’s placement within the broader Te Anau basin, a significant geographical feature in southern New Zealand that influences local weather patterns and wind resources. The specific micro-location is identified as the Waiau river valley. This valley setting is critical for wind energy projects, as it can channel and accelerate airflow, potentially enhancing the efficiency of the turbine units. The topography of the Waiau river valley, combined with the proximity to the larger Te Anau basin, creates a landscape that is both open and defined by natural drainage lines.

Land Use and Vegetation

The current land use at the Jericho Wind Farm site is characterized by agricultural activity and managed vegetation. The area is primarily utilized as farmland, indicating that the proposed infrastructure will be integrated into an existing rural economic landscape. This agricultural context is typical for wind farm developments in New Zealand, where landowners often lease portions of their properties for turbine placement while maintaining farming operations. The presence of farmland suggests that the ground conditions are suitable for the construction of access roads and foundations required for the eight proposed turbines. Additionally, the site features shelter belts. These are linear plantings of trees or shrubs used in agriculture to protect crops and soil from wind erosion and to provide microclimatic benefits. The existence of shelter belts indicates a history of land management aimed at optimizing agricultural productivity in the region. The integration of wind turbines into an area with existing shelter belts requires careful planning to minimize visual impact and potential interference with the agricultural functions of the trees. The combination of open farmland and structured vegetation like shelter belts creates a varied visual environment that the wind farm will need to complement or contrast with, depending on the design and height of the turbines.

The location near Blackmount further contextualizes the site within a region known for its rugged terrain and natural beauty. Blackmount itself is a locality that serves as a reference point for the wind farm’s accessibility and proximity to local communities. The distance from Manapouri and Tuatapere provides a sense of the site’s relative isolation or connectivity to larger population centers. Manapouri is a well-known town in the area, often associated with hydroelectric power generation and tourism, while Tuatapere is another key settlement in Southland. The Jericho Wind Farm’s position between these two towns places it in a strategic location for potential grid connections and community engagement. The Waiau river valley, as the specific site, offers a natural corridor that may facilitate the transportation of large turbine components, such as the blades and towers, which are essential for the construction of the 35 MW facility. The environmental context of the site, therefore, includes not only the immediate land use and vegetation but also the broader geographical features that influence the feasibility and impact of the wind farm.

The proposed development must also consider the environmental sensitivity of the Te Anau basin. This basin is a significant ecological area, potentially supporting diverse flora and fauna. The integration of a wind farm into such an environment requires assessments of the impact on local wildlife, including bird and bat populations, which are often key considerations in wind energy projects. The height of the turbines, which are proposed to be up to 210m high, and the rotor diameter of up to 160m, will interact with the local landscape in ways that need to be evaluated for environmental compatibility. The shelter belts and farmland provide a baseline for understanding the current ecological state of the site, but the introduction of large-scale infrastructure will alter this balance. The location in the Waiau river valley also implies potential hydrological considerations, such as drainage patterns and soil stability, which are important for the long-term operation of the wind farm. Overall, the site location and environmental context of the Jericho Wind Farm are defined by its placement in a productive agricultural valley within a significant geographical basin, near established communities and natural features.

Development History and Consenting Process

Development of the Jericho Wind Farm began with preliminary site assessment in the 2010s, characterized by the installation of a monitoring mast near Blackmount in Southland, New Zealand. This early phase established the wind resource data necessary to justify the proposed 35 MW capacity of the project. The land assembly strategy was initially anchored by Landcorp, a major state-owned enterprise in New Zealand, which held significant ownership stakes in the surrounding agricultural and pastoral lands. This ownership structure provided a consolidated land base, simplifying the initial feasibility studies and access rights required for a wind farm of this scale.

In 2018, a pivotal shift occurred in the project's ownership and development trajectory when Landcorp sold its stake in the site. This transaction transferred the development rights to a new operator, setting the stage for more aggressive planning. Following this acquisition, the Southern Generation Limited Partnership emerged as the primary driver of the project. In 2022, Southern Generation Limited Partnership officially announced the Jericho Wind Farm, detailing the technical specifications including eight turbines reaching up to 210m in height with rotor diameters of up to 160m. This announcement marked the transition from preliminary monitoring to formal proposal, engaging local stakeholders and initiating the regulatory review process.

The consenting process accelerated significantly in 2024, leveraging New Zealand’s updated legislative framework for renewable energy infrastructure. The proposal was accepted for fast-tracking by Minister Penny Simmonds. This fast-track acceptance is a critical procedural milestone, designed to streamline the approval timeline for major energy projects, reducing the duration of public inquiries and committee of the whole debates. The involvement of Minister Penny Simmonds underscores the national priority placed on expanding wind capacity in the Southland region. This regulatory progress follows the initial 2010s monitoring and the 2018 land sale, completing a decade-long development arc from data collection to formal ministerial recognition.

Grid Connection and Infrastructure Integration

The Jericho Wind Farm is designed to integrate into the existing electrical infrastructure of Southland, New Zealand, relying on a specific connection to the regional grid network. The facility will connect to the 66 KV ring circuit, which is owned by The Power Company Ltd. This connection point is critical for transmitting the generated electricity from the wind turbines to the broader distribution and transmission systems in the region. The integration with this specific voltage level allows the wind farm to feed power efficiently into the local grid, supporting the energy mix of the Southland area.

Integration with other energy assets in the vicinity is a key aspect of the project's infrastructure planning. The Jericho Wind Farm is positioned to work in conjunction with the Monowai Hydro power station and the White Hill Wind Farm. This clustering of renewable energy sources in the Southland region helps to optimize the use of transmission lines and substations. The proximity to these established facilities allows for a more cohesive management of power generation and distribution. The Monowai Hydro station provides a baseline of hydroelectric power, while the White Hill Wind Farm offers additional wind-generated energy, creating a diversified renewable energy portfolio in the area.

The link to the North Makarewa substation serves as a crucial node in this infrastructure network. The substation acts as a collection point for the electricity generated by the Jericho Wind Farm, as well as potentially from other nearby sources. From the North Makarewa substation, the power can be stepped up or down in voltage as needed before being fed into the 66 KV ring circuit. This substation connection ensures that the electricity from the eight proposed turbines can be effectively managed and distributed. The infrastructure at North Makarewa is therefore a vital component in the successful operation of the Jericho Wind Farm, facilitating the flow of energy from the turbines to the end consumers in Southland.
