Definition
Distributed Small-Scale Wind (SSW):
A wind project with 3 or less utility-scale turbines connected to the local lines network
Typical project size between 0.5 – 5 MW
![Page 4: Distributed Small-Scale Wind in New Zealand: Advantages, Barriers and Policy Support Instruments](https://reader036.vdocuments.us/reader036/viewer/2022062305/56815465550346895dc27e32/html5/thumbnails/4.jpg)
Aim
To establish whether distributed, SSW in NZ is worthy of public policy support and if so, determine the most effective policy instruments to promote its uptake.

Key Issues
NZ wind industry is failing to capitalise on the world- class wind resource it has available
![Page 12: Distributed Small-Scale Wind in New Zealand: Advantages, Barriers and Policy Support Instruments](https://reader036.vdocuments.us/reader036/viewer/2022062305/56815465550346895dc27e32/html5/thumbnails/12.jpg)

Key Issues
Trend toward large-scale (local opposition)
Limited flow of investment
Limited manufacturing capacity High geographic concentration
NZ wind industry has adopted 4 characteristics that are limiting its future potential growth:
There is arguably a need to reassess the way the industry is developing
![Page 15: Distributed Small-Scale Wind in New Zealand: Advantages, Barriers and Policy Support Instruments](https://reader036.vdocuments.us/reader036/viewer/2022062305/56815465550346895dc27e32/html5/thumbnails/15.jpg)

Trend toward large-scale
NZ wind developers favour the ‘big is better’ approach
• 98% of installed capacity comes from farms with 15 or more turbines
Leading to increased local opposition & lengthening consent processes
– E.g. Project West Wind delayed more than 15 months
– Also Project Hayes, Awhitu, Tararua 3, Te Waka Ranges
Social acceptance is a key limiting factor of wind’s potential growth, e.g. UK
![Page 17: Distributed Small-Scale Wind in New Zealand: Advantages, Barriers and Policy Support Instruments](https://reader036.vdocuments.us/reader036/viewer/2022062305/56815465550346895dc27e32/html5/thumbnails/17.jpg)
• 98% of total generating capacity being owned by only three developers
– Meridian & Trustpower also investing in Australia
c.f.– Ireland: More than 40 investors– Denmark: More than 150,000 households
Limited flow of investment

Advantages of SSW
Increased local public acceptance
Facilitates community ownership
Supports local manufacturing
Potential for distributed generation benefits
Utilises small high-wind sites

Advantages of SSW
1. Increased local public acceptance
‘Big is better’ is possibly creating an anti-wind sentiment
A spread of turbine clusters throughout NZ will give people a chance to familiarise themselves with wind on a scale that they find more acceptable and less intrusive
![Page 24: Distributed Small-Scale Wind in New Zealand: Advantages, Barriers and Policy Support Instruments](https://reader036.vdocuments.us/reader036/viewer/2022062305/56815465550346895dc27e32/html5/thumbnails/24.jpg)

Advantages of SSW
2. Facilitates community ownership
Proven to increase local public acceptance:
•Greater tolerance of effects
•Removes hostility toward large, commercial developers
•Alleviates tensions between local and national interest
A new source of capital:
•Greater investment pool
•Increases competition in generation
•Increases geographic diversity of wind capacity

Advantages of SSW
2. Facilitates community ownership
Involves farmers in wind:
•Utilise NZ’s vast rural potential for electricity generation
•Opportunity for farming sector to partially offset emissions
•Reduce the need for intensifying land use
Has demonstration value for the public:
•Improve understanding of the link between energy and climate
•Increase awareness of energy conservation

Key Findings
Source: (BMU, 2006) Source: (BMU, 2006)
• SSW has the potential to alleviate issues in the wind industry & the wider energy sector
• Developing SSW would likely provide faster industry growth
Faster consent processes
More investors
Greater number of suitable sites (cf. large wind farms)

Key Findings
Source: (BMU, 2006) Source: (BMU, 2006)
• People are significantly more positive about SSW being developed in their local area
• The NIMBY effect is significantly reduced with SSW
SSW should not be developed instead of large-scale wind farms, but rather alongside them
• Rural landowners in NZ are interested in community ownership
