Harapaki Wind Farm, Hawke’s Bay, New Zealand

Situation

Meridian Energy, a New Zealand government-owned electricity generator and retailer, is responsible for the construction of the 176MW Harapaki Wind Farm in Hawke’s Bay. As the country’s second-largest wind farm, Harapaki will generate enough clean energy to power over 70,000 homes each year. With an investment of NZD395 million (approx. £187 million), the project plays a key role in supporting New Zealand’s renewable energy goals. Given the scale of power generation and harsh terrain, the infrastructure required robust cable restraint solutions to ensure safety, reliability, and performance across exposed and high-stress environments.

Solution

Ellis, in partnership with their dedicated New Zealand distributor, OHUG supplied Colossus™ & Protect™ Cable Cleats, designed specifically for large diameter cables and high voltage scenarios typical in major power generation projects such as wind farms. Built to withstand extreme mechanical forces, the combination of both the Colossus™ & Protect™ cleats provided a secure and long-term solution for restraining critical power cables throughout the Harapaki site.

Key advantages included:

• High-strength construction to handle large diameter cables and withstand extreme short circuit conditions.

• Durability and resilience ideal for exposed and elevated installations common in wind energy infrastructure.

• Ease of installation, even in remote or uneven terrain, supporting efficient deployment under challenging site conditions.

By combining the engineering strength of Ellis Colossus™ & Protect™ cleats and the expert on-the-ground supply and support from OHUG, the Harapaki Wind Farm ensured its cabling infrastructure was safeguarded against electrical and mechanical risks, contributing to the resilience and longevity of this nationally significant renewable energy asset.
