Energy3 provides development advice to those interested in developing a wind farm. Energy3 uses a √ístaged gate√ď approach to wind farm development. This aims to provide a cost effective solution for landowners and investors where the risks of development are managed at each stage of the development process.

  • Stage 1 Site Assessment and Project Economics
  • Stage 2 Pre feasibility engineering and preparation of Consents
  • Stage 3 Feasibility Engineering and turbine procurement
  • Stage 4 Construction, installation and commissioning

Stage 1 Wind Analysis, Site Assessment and Project Economics

Wind data is analysed first. The first stage of development process reviews whether the physical resources necessary for wind farm development are present at a site; including site access, wind resources, electricity lines connections and electricity price.

Stage 2 - Pre feasibility Engineering and preparation of Consents

Before further engineering project work is undertaken, the requirements to obtain a resource consent are carefully considered. This includes amongst other things assessments of ecology, communication interference, visual, noise and community impacts. If this process of assessment does not indicate a reason why a wind farm should not be constructed, then a resource consent application is prepared and submitted. Concurrently, detailed engineering and commercial evaluations are conducted to assess the construction requirements, and ensure that acceptable commercial terms can be agreed for connection into the local distribution network and for the sale of generated electricity.

Stage 3 - Feasibility Engineering and Turbine Procurement

Turbine selection represents the most important decision for the project; involving consideration of cost, availability, logistics / transport options, installation (crane) requirements, local technical and engineering support, condition (if reconditioning is considered) and network compatability, Feasibility engineering takes the project through financial close where turbines, electrical equipments and sub contractors are selected, costs for equipment and installation are refined, risks to construction have been managed, agreements with local distribution companies for connection and retailers for sale of electricity have been signed. Finally, contracts are entered into for turbine purchase and major subcontractors are appointed.

Phase 4 - Installation / commissioning

If second hand turbines have been selected, the project firstly undertaked detailed inspection and reconditioning as necessary against operating specifications. Installation tyhen proceeds with the mobilisation of equipment and contractors to carry out the necessary civil, electrical and installation works. The project is completed with commissioning, final connection to the local distribution network and handover to the operating entity.

Energy 3 - capability

Energy3 recognizes that successful distributed wind farm development requires a tight control over costs to ensure that projects are viable. Energy3 provides a wide range of services to clients who wish to develop distributed generation projects of a modest scale. Owns and operates two small scale wind farms; and has consented a number of other wind farms.


Energy 3 - turbine

The capital cost of second hand turbines is less than half of a new turbine, while the operating life of the turbines can be extended with professional reconditioning of major rotating parts and consumable items such as mountings and brakes prior to re installation. To ensure these sitescan be developed, of which there are many in New Zealand close to existing lines, Energy3 has relationships with suppliers of second hand turbines from Europe.
