Yanco Delta

Wind and Energy Storage

Project Details

The Yanco Delta Wind and Energy Storage project
“Yanco Delta” is a significant energy infrastructure initiative in the Riverina area of NSW. It is a project development intended to make a difference as Australia transitions away from fossil-fuel generation and toward a cleaner and more renewable energy future.
Australia is still very dependant on coal-fired power generation, for both system capacity (the ability to provide electrical power quickly) and for vast volumes of electrical energy throughout the course of any particular year. Australia’s dependency on coal-fired generation comes at a cost, however. Coal-fired generation is no longer the cheapest form of electricity by volume (renewables generally is). Coal-fired generation is also a significant contributor to CO2 and other undesirable emissions. Furthermore, coal-fired generation is aging and becoming less reliable. These three things amount to environmental, economic and energy security concerns for all of us.
Yanco Delta is one of the largest on-shore wind and energy storage developments in the country – and for good reason. Yanco Delta is a solution in the making. It has both the scale and proposed technologies to provide system capacity and vast volumes of energy annually. The proposed 208 wind turbines offer up to 1.5GW of nameplate capacity and associated electricity volume in the market. The proposed 800MWh of batteries, with potential for further expansion, offer additional capacity to the system. This makes
Yanco Delta a genuine contender to displace old, polluting coal-fired generation in Australia, and therefore, help clean up our future.
Yanco Delta is a development under the care and custody of four Virya Energy executives with more than 80-years of combined international renewable energy experience. This makes it more than just a wind and battery project. It is an undertaking that considers the environment, cultural heritage, community and safety.

Yanco Delta Key Benefits

The Project’s construction is expected to last for years and employee hundreds of people.

The on-going operations and maintenance would last for decades and employ scores of mechanical and electrical technicians as well as supervisory and administrative roles.

The details of this will become more quantifiable as the project development matures and nears its Final Investment Decision (FID)

Yanco Delta would deliver low-cost, renewable energy to the grid and support the NSW 82% renewable energy by 2030 and 2050 net-zero emissions targets

The Project would provide financial contributions to landowners, helping to ‘drought-proof’ their farming operations

The project would fund landmark projects in consultation with both local Councils and the community

How does a wind farm work?

The natural power of the wind turns the blades of a rotor. This rotor is connected to a gear box via a low-speed shaft.
The gearbox is connected to a generator via a high-speed shaft which rotators to produce electricity.
Transformers convert this electricity from low to high voltage, which is the transmitted via supporting electrical infrastructure such as transmission line to the substation and then a terminal station.

How many turbines will there be?

There will be up to 210 wind turbines as part of the Yanco Delta Wind Farm.

The turbines will be located across eight different private properties, which the infrastructure sitting across 33,000 hectares.

Virya Energy has entered into landholder agreements with each of the eight landholders.

How tall are the turbines?

The wind turbines will be up to 270 m tall from the bottom of the tower to the tip of the blade.

What are the stages of a wind farm project?

A wind farm Project will have a full lifespan of around 40 years and can be broken down into the following phases:

  1. Project development
  2. Community consultation
  3. Environmental approvals
  4. Planning and financing generally take 4-7 years to complete.
  5. Construction and commission
  6. Operation
  7. Upgrading or decommissioning

The construction and commissioning period will generally take around 2-3 years and once commissioned, the operational life of a wind turbine is currently around 30 years.

At the end of this time the turbines can be refurbished or upgraded or alternatively the wind farm may be decommissioned, and the landscape is returned to its former condition.

What are the environmental benefits of wind farms?

Wind energy is a clean, renewable and reliable energy source, and is a significant contributor toward the transition of our energy system away from emissions intensive sources.

Zero emissions are created during the generation of electricity by wind turbines, and any emissions generated in the manufacture, construction and maintenance are offset within a year of operation.

The land, biodiversity and environmental impacts of wind farms are significantly lower than those created in mining and burning fossil fuels.

In addition, most turbine components are now recyclable with the valuable steel, copper and aluminium, as well as the carbon fibre blades, all being recycled.

How does the community benefit?

Virya believes in sharing the benefits of its wind farms with the local community.  Many local businesses will be engaged to work directly on the project, employing local people.  There is a significant benefit in increased economic activity in the region through accommodation, food and equipment hire, as well as a drought proof income to landowners, who in-turn spend more in the local economy.

In every community we build our projects, we work in partnership with the community and listen to the community’s needs through both formal and informal community consultation.  We will also establish a community benefit fund for local organisations and projects, and a community committee will determine how that funding is distributed to best support the region.

Will there be any noise impacts?

Audio impacts from the operation of the turbines are assessed and mitigated as part of the extensive environmental approvals process, and this includes designing a suitable buffer between turbines and any residences to reduce any impact on neighbouring properties.  When operational, the movement of the blades through the air generates some noise, and how loudly this is experienced varies with wind speed, topography and other factors.  Advances in turbine design have reduced the noise impacts, and a normal conversation can be held when standing below a turbine without needing to raise your voice.

The table below gives an indication of the noise levels to be anticipated at a distance of 500-1000m from a turbine, in the context of noise levels we experience every day, although Virya will not place a turbine within 2km of a neighbouring dwelling, ensuring noise levels are even lower than required.

In every community we build our projects, we work in partnership with the community and listen to the community’s needs through both formal and informal community consultation.  We will also establish a community benefit fund for local organisations and projects, and a community committee will determine how that funding is distributed to best support the region.

Can wind farms impact health?

A study by the NHMRC, Wind Turbines and Health, A Rapid Review of the Evidence, (July 2010) found that “there is no evidence for direct adverse health effects from these [wind turbine] installations.”

Do wind turbines cause fires?

On very rare occasions some turbines have experienced  electrical or mechanical failures that have started fires.

These fires are generally contained in the top of the turbine, with turbine monitoring systems alerting fire crews, who can then ensure no spot-fires start at the base of the tower.

Modern wind turbines are also fitted with fire suppressant systems to automatically put out fires and the regular maintenance of equipment greatly reduces the chance of fires being started.

State and Federal fire authorities have consistently stated that they do not consider wind turbines to be a fire risk and that the access tracks act as fire breaks, while also providing good access for fire trucks to otherwise inaccessible areas.

Do wind farms harm wildlife?

Wind farms have little impact on most birds and bats as they predominantly fly below the swept area of the blade.

Some migratory birds and soaring birds, such as eagles, do fly at the height of the blades. As such, flight paths studies are carried out to make sure that turbines are not placed in migratory flight paths or near cliffs where birds soar.

Ground studies are also undertaken to identify habitat of vulnerable land dwelling animals. Considering wind farms use less than 1% of the property they are located on, there is plenty of room to reposition turbines, tracks or cable routes away from areas of potential impact, avoiding or minimising habitat removal.
