FAQs
A selection of answers to questions you may have about the Bretherton Energy Partnership:
Asland Walks Energy Park – Wind and Solar Farm | Energy | Resident Questions
How noisy will the wind turbines be and will these be heard from the village?
No, the wind turbine would generate very little noise, which would be under 35dB, to give a comparable example a typical library or bird call is generally around 44dB. A number of different layouts were considered and it was determined that it would only be possible to fit one wind turbine within the developable area at the Sollom site. This is because the cumulative noise levels of two or more turbines would exceed the 35 dB LA(90) noise limit at nearby residential properties for all layouts considered.
Additionally, in accordance with planning requirements, a 4-week noise assessment study took place, noise monitoring equipment was placed in residents garden’s closest to the Asland Walks site, these where in four locations being to the north, east, south east and south west of the site. Noise modelling then is taking place to determine if there is any noise impact on residents, with initial results showing there is no noise impact.
Are migrating or native birds at risk of collision with the wind turbine?
No, bird radar technology will be installed on the wind turbine control system, the bird radar detects single or bird flock flight paths within a 3-mile radius, if the flight path is at risk with collision with the turbine, the radar shuts down the turbine to prevent bird collision.
Will the wind turbine affect the already bad TV and mobile phone signal in the
area?
No, necessarily design and planning work is carried out between the turbine design team and the cellular/radar system providers to ensure the turbine location does not affect the area’s TV and mobile phone signal.
How much carbon will the wind farm and solar panels offset?
Around 12,000 tonnes of carbon emissions would be offset by the wind, solar and biogas plant renewable generation, that amount of carbon is equivalent to 2,254 petrol passenger cars driven for a year.
Will the local ecology and habitat be affected by the Aslands Walks Energy Park?
No, the local ecology and habitat at the Asland Walks Energy Park will actually improve, this is because current the site is cropped. The Asland Walks Energy Park ecology and habitat will be developed by the planting of 15,000 trees bordering field to provide a visual screen and increase wildlife habitats, plus the solar panel arrays provide further shelter for local ecology, and are proposed to be grazed by sheep. Additionally, as it has been demonstrated by the ecological studies carried out on the field and surrounding areas, the proposed renewables would not have an impact or cause ecological loss on wintering foraging birds, And as the entire field is now no longer required for solar panels, further ecological enhancement can take place to create habitats for Skylarks and similar species
Why does there need to be both renewable solar and wind generation?
Feasibility studies have made evident that the seasonal generation profile for solar is complementary to wind, as the best solar resource is typically in the summer while the best wind resource is typically in the winter.
Therefore, both technologies are best combined to achieve greater optimisations between project sizing, peak energy demands and load profiles.
How much surplus energy and money would BEP stand to gain on an annual basis?
Based on current wind, solar and biogas proposals and current site demands the Bretherton energy partnership stand to receive around £200,000 – £350,000 per annum from surplus electricity generated.
The agreement proposed by GAG is that, provided the income generated is used for the provision of the Bretherton distribution and energy infrastructure, then 100% may be retained.
GA is a large and continually expanding company, will there always be surplus energy for the energy partnership?
Yes, due to the variability of wind and solar energy plus the variations in pet food production thus site power demand at Plocks Farm there will always be surplus energy provided to Bretherton.
Do I require a smart meter to be a participant?
Yes, a smart meter is required and can be obtained through the energy supplier Octopus.
You can create an account and request a smart meter at octopus.energy/login/?next=/dashboard/smets2-interest
What is the catchment area of the 280 houses included in the partnership?
The area under consideration are all properties within the Parish Boundary of Bretherton. However, the deployment of the proposal will be in a step by step way and will seek to ensure the maximum number of properties are connected as soon as possible. This may cause a number of outlying properties to be delayed, or it may prove to be uneconomic to connect every property within the parish.
Why is the proposed wind turbine located at Asland Park and not offshore or other location?
To provide low-cost electricity directly to the GA factory and parish, the wind turbine needs to be connected via a ‘private wire’, so that is does not suffer from the transmission losses, or the usage costs of the National Grid, which has limited capacity
How tall will the turbine be?
The proposed wind turbine with a maximum rated output of 4.2 megawatts will have a rotor diameter of 138m. The tower will be 130m high. The tip of the blades will reach height of 200m. For comparison, the wind turbines on Mawdesley Moss are 55m high.
How noisy will the wind turbines be and will these be heard from the village?
You can stand under a wind turbine and hold a normal conversation without raising your voice. The sound you hear is the swoosh of the blades passing through the air. Compared to other sources of noise (such roads or the wind in the trees), wind turbines are not noisy.
Noise from turbines is taken very seriously throughout the planning process and a noise study will be an integral part of the environmental impact assessment required for planning permission. Planning consent will only be granted if it can be demonstrated that the wind turbine will not be a noise nuisance to nearby houses even when the background noise level is at a minimum, for example at night. Independent noise surveys will be required, and the methodology agreed with the Environmental Protection Team at the Chorley Council.
What about ‘shadow flicker’?
Shadow flicker can occur inside a building when the sun shining through a wind turbine’s rotating blades creates a rotating shadow on the ground, which causes a flickering effect if the shadow passes across a window into a building. The adverse effects of shadow flicker from large commercial-scale wind turbines is one of nuisance, but there are no associated adverse health effects.
Certain weather conditions are required in order for shadow flicker to occur:
• The turbine must be close enough to a building for its shadow to be cast over the building
• The sun must be low in the sky, with no clouds
• The sun, turbine and window must be lined up so that the rotating blades cast a shadow on the window
The potential for shadow flicker must be considered as part of the pre-planning environmental impact assessment. Shadow flicker is predictable, and a turbine can be programmed to shut down if this is required.
A full report has been commissioned to identify the potential flicker, and glare. This will be included in the “Resources “ Tap , as soon as this becomes available.
Will the local ecology and habitat be affected by the Aslands Walks Energy Park?
No, the local ecology and habitat at the Asland Walks Energy Park will actually improve, this is because current the site is under arable cropping. The Asland Walks Energy Park ecology and habitat will be developed by the planting of 15,000 trees along the boundaries of the site bordering field to provide a visual screen and increase wildlife habitats, plus the solar panel arrays provide further shelter for local ecology. Additionally, investigations are being undertaken to identify potential mitigation sites, to minimise any impact on the winter feeding grounds of the Pinked footed geese and Whooper Swans, during a two-year monitoring period which commenced in September 2022.
Are birds at risk of collision with the wind turbine?
When choosing a site for a wind turbine, careful consideration needs to be given to impact on wildlife from both the construction works and the operation of the turbine. Both can be managed through good site selection and design (e.g. locating turbines away from sensitive habitats and flight paths for birds and bats).
The impacts from construction works are similar to any development (earth works from construction of roads and foundations etc). The key species that may be impacted by the operation of the turbine are birds and bats. In most cases both will avoid flying into wind turbines. https://www.windpowermonthly.com/article/1697603/almost-no-birds-die-collisions-wind-turbine-blades-research-finds
Habitat loss, traffic and domestic cats are a much greater man-made threat. With the exception of a few isolated cases due to poor siting, wind farms have not been associated with any major adverse effects on bird populations. By far the biggest threat to birds and other wildlife is climate change, which can be mitigated by the replacement of fossil fuel generation with renewable energy generation such as wind power. Environmental assessments and consultation with wildlife bodies are a statutory requirement as part of the planning process, which ensures wind turbines are properly sited to minimise effects on wildlife.
Will the wind turbine affect the already bad TV and mobile phone signal in the area?
No, necessarily design and planning work is carried out between the turbine design team and the cellular/radar system providers to ensure the turbine location does not affect the area’s TV and mobile phone signal.
How much carbon will the wind farm and solar panels offset?
Around 19,000 tonnes of carbon emissions would be offset by the wind andsolar renewable generation, that amount of carbon is equivalent to 4,132 petrol passenger cars driven for a year.
Why does there need to be both renewable solar and wind generation?
Feasibility studies have made evident that the seasonal generation profile for solar is complementary to wind, as the best solar resource is typically in the summer while the best wind resource is typically in the winter.
Therefore, both technologies are best combined to achieve greater optimisations between project sizing, peak energy demands and load profiles.
GA is a large and continually expanding company, will there always be surplus energy for the energy partnership?
Yes, due to the variability of wind and solar energy plus the variations in pet food production thus site power demand at Plocks Farm there will always be surplus energy provided to Bretherton. Under the proposal Bretherton residents will receive the “first bite of the cherry”, being the first 5% of any generation available.
Do I require a smart meter to be a participant?
Yes, a smart meter is required and can be obtained through the partner energy supplier to the Bretherton Energy Local Club (e.g. GEUK or Octopus).
Will every house in Bretherton be able to benefit?
The area under consideration are all properties within the Parish Boundary of Bretherton. However, the deployment of the proposal will be in a step-by-step way and will seek to ensure the maximum number of properties are connected as soon as possible. This may cause a number of outlying properties to be delayed, or it may prove to be uneconomic to connect every property within the parish. The properties of Barrowford House and Red Bridge Farm, will receive a direct feed to their property, and not through the Community Battery, but would still be included in the 5% available to Bretherton Residents.
What if I don’t live in Bretherton?
Unfortunately, you cannot be a member of the Bretherton Energy Local Club, as the proposal is to only supply residents of Bretherton with electrical energy from the Asland Walks Energy Park.
How much will I save on my bills?
At the moment there isn’t a definitive answer to this question. The financial model of the Bretherton Energy Club means that the operating, management and administration costs need to be covered before any surplus could be shared with the local community. Feasibility studies are currently being carried out that will help to provide a clearer understanding of what these costs might be. Once this information is available it will be shared with the community along with a clearer picture of what savings could look like.
Scale and Visual Impact
I need to understand the visual impact of the wind turbine on the area. I had no idea the turbine was 150m high.
At this stage a single turbine is proposed, being 130m to the central Hub. The tips of the three blade rota will rise to 200m in height. A photo montage, of the completed site from Red Bridge, Eyes Lane, can be seen below. (Coming Soon)
Seeing what the proposed solar structures would look like on a map/location of the 80 acres would be helpful.
A plan showing the solar panels and wind turbine can be seen at this link. The solar panels face to the west and east, rather than the normal south facing, as this enables more sunlight to be captured during the day and also spreads the intensity over the whole day, rather than just in the middle of the day.
How tall will the turbine be?
The proposed wind turbine with a maximum rated output of 4.2 megawatts will have a rotor diameter of 138m. The tower will be 130m high. The tip of the blades will reach height of 200m. For comparison, the wind turbines on Mawdesley Moss are 55m high.
But what about the people who live near the wind turbine? The noise and how ugly will it be?
The noise generated by the Wind Turbine, when measured from a distance of 600m away is under 35dB, to give a comparable example a typical library or bird call is generally around 44dB. All residential properties are at least 600m away from the turbine. The photo montage here (coming soon) shows a view of the completed Asland Walks Energy Park from Red Bridge looking north being in 2038. The tree planting undertaken during the Spring of 2023 will screen most of the solar panels when established, as shown in the photo montage.
Clarity on who will benefit and what benefits are
The benefit to the parish and the certainty of said benefit is not explained simply and clearly.
A simple explanation is as follows:-
- It will take several years to get planning permission, and then a further 10 years or so to build out the wind, solar, batteries and electrical infrastructure at an estimated total of £30m, all of which will be paid by GA. Bretherton Energy, a community owned company, will receive 5% of all the electricity generated from the site, at no cost, as soon as it starts to generate electricity, which can be sold or used directly by Bretherton residents having passed through a battery, so there is a “break” between the electricity Grid and electrical energy from Asland Walks
- Electricity will initially be sold at the wholesale market rates to the Grid (or GA). This will allow income to build up within Bretherton Energy to be able to buy the battery which may cost £2.7m when fully operational.
- To allow Bretherton Residents to use this physical energy (which is worth some five times more to residents themselves, than the money received when sold to the Grid), it will require two batteries, one to charge and one to discharge, so there is no physical electrical connection between the Grid and the private wire connection from Asland Walks.
- As Bretherton is fed from two electrical networks, it will require a complex battery system and electrical infrastructure to feed the whole of Bretherton, which will take time to install.
- When the battery system does not have sufficient power, then electrical energy will be provided by the Grid, as it currently does. The appointed Electricity Supplier will charge the current rate from the Grid, and a lower rate from Asland Walks that is fed into the Grid via the batteries.
- The whole project will be administered by Energy Local Bretherton, a community owned and managed company that is supported by the National Organisation Energy Local, who currently have 21 other similar schemes (at different stages of development), but this will be their largest scheme to date
- When the site is fully operational, if all of the electricity is sold to the Grid (or GA), it is estimated to £101,000/yr worth of income. If residents receive all this electrical power directly, it will displace electrical costs of between £486,000 – £572,000/yr for residents of Bretherton, being approximately £2,000 per person, depending on electrical cost, taxes and levies being incurred at the time. The wind turbine and solar panels will last for 25 years, after which time the planning permission will require its complete removal.
The information provided is scant and whilst the solar seems ok, 150m turbine is huge. CGI, drawings, plans, elevations
As part of the culture and heritage assessments being undertaken, technical detailed photo montages showing the visual appearance of Asland Walks Energy Park and their impact on listed heritage properties will be prepared and circulated. The photo montage currently on the website is an “artistic impression” not a fully Compliant CGI illustration due to the time available, but will be completed in the near future.
We are in support of the scheme in principle but for solar power not on shore wind, which will be a blight on our community and eyeline. Wind power is a great solution but should be off shore farms and areas of low human and bird population
Unfortunately, in Lancashire the sun does not regularly shine. However, the wind is more reliable and generally available throughout the day and night. As part of the site assessment, the available wind speed and direction will be monitored for at least two years, to be able to fully assess as to what the options are in terms of the size and dimensions of the wind turbine.
Energy Local proposal all seems a bit vague. How will the community energy partnership work? Which homes will be excluded?
Energy Local have produced a document setting out how it will work. See this link (Coming soon)
There are many aspects of the model that is unclear. How do parts of the village benefits if different parts of the village are connected to different substations?
The electricity from Asland Walks will directly feed a battery. Then based on historical electrical consumption and anticipating the future electrical demand, the Battery Manager would release onto the distribution network the estimated amount of electrical power that will be consumed by Bretherton residents and member of the scheme. In this way, the electrical network has the required electrical energy in order to provide the Energy Local Bretherton members with the required electricity to use.
The battery itself is required to provide an electrical energy “break” between the Grid and the source of supply, so that no electrical (loop) can be established, caused by having two points of connection to the Grid. Bretherton is served by two primary substations which currently serve the majority of residents throughout the village, so a separate battery is needed for each substation
How would you supply everyone in the village? There are more than one electricity power source. Will it include homes on the outskirts?
The Bretherton Grid is fed primarily by two primary distribution points, being Bretherton North (south of North Road) and Bretherton South (behind the school on South Road). A complex battery system and electrical infrastructure is required at each point to feed the vast majority of homes throughout Bretherton, the required detail is being discussed and to be confirmed with ENWL.

People on the outskirts of the village are usually ignored
It is certainly not the intention to ignore people on the outskirts of Bretherton Village. As far as practical, the opportunity will be available to all and where this is not practical, then the intention would be to compensate the residents in some way, so that all residents at least have the opportunity to join the scheme, if they so wish.
Cost of the Scheme and how financed.
What is the cost to install this and how long will it take to pay off the capital? What are the running costs and who is responsible for maintenance and operation?
It In terms of the Asland Walks Energy Park, GA Pet Food Partners will provide the wind turbine and solar panels, which are likely to cost some £30m. To enable residents to use the electricity generated themselves, they will require a battery to provide that needed “break” between the point of generation and the Grid.
How much will residents need to pay to finance the battery storage? What about those who can’t afford to? What would the costs be? Would it be available to all?
The residents themselves will not physically have to pay for the battery. The money for the battery will be accrued from the electrical energy sales. As and when sufficient monies have been accrued, or the community company feel it is financially viable for them to do so, they can borrow the needed capital to purchase the battery in order to have the physical benefit of the electrical power as opposed to just selling the electrical power, to the Grid at the wholesale market price.
However, it is entirely up to the community company to decide, but with no risk to residents. It is the intention of the scheme to make it available to all residents if they wish to join the scheme.
How would those who can’t take part be compensated?
There are two residential properties, Red Bridge Farm and Barrowford House that are not connected to the Bretherton electrical supply network. It is therefore proposed that they would receive a direct link from the Asland Walks Energy Park, so that they can take part in the scheme in a similar manner.
At this stage, we are not aware of any other residents that cannot receive electrical energy and be part of the scheme. If there are such residents, then the community company would seek to compensate them, so as to receive a similar benefit, as if they wished to take part.
Community Enterprise – What are the costs?
As GA Pet Food Partners are providing 5% of the electricity generated at no cost to the community enterprise, that can either be sold or utilised by residents, there is no cost.
What is the long term security of the enterprise?”
In terms of long term security of the enterprise, the operation and use of the park is protected by a Section 106 legal agreement, established as part of the planning permission granted between Chorley Council and the Land Owner. This legal agreement will bind the land owner and the operator that uses the equipment to contribute 5% of the generation to residents of Bretherton. Therefore, if GA Pet Food Partners was to go out of business, then the subsequent owner of Asland Walks Energy Park would be bound by the Legal agreement that if they continued to generate electricity, then 5% would be required to be provided to the community enterprise. If electrical generation ceased all together, then the Legal Agreement would require the remove of the wind turbine and the solar panels.
It needs a definitive proposal with approx costs. How will the cost be funded and what would be the timescale for installation? What are the projections for return of energy after all these overheads are taken into account?
It needs a definitive proposal with approximate costs. How will the cost be funded and what would be the timescale for installation? What are the projections for return of energy after all these overheads are taken into account The previous questions have dealt with cost and how the community enterprise is funded. Set out below is the proposed timescale.
The potential timing and phasing of the scheme is as follows: –
• Tree Planting Year 1 and Year 2
• Two-year Bird Study & Wind Speed Monitoring Year 2
• Pre-Application Year 2
• Planning Application Year 3
• Planning Approval & Section 106 Year 4
• Wind Turbine Construction Year 5
• Phase 1 PV Year 8
• Phase 2 PV and Phase 1 of BESS Year 10
• Phase 3 PV Phase 2 of BESS Year 12
• Phase 4 Phase 3 of BESS PV Year 14
As mentioned previously, the estimated cost is some £30m. GA Pet Food Partners proposes to phase the build so that it can fund the development.’
Solar field – would it be fenced off? How would it affect wildlife? How might it affect surface water drainage?
Yes, the solar panels will be fenced as theft of the panels is a major concern. In addition, in the most vulnerable areas, there will be a ditch and tree planting to help limit and prevent unauthorised access. However, the current footpath along the River Douglas, and the towpath along the canal will be widened to provide better access, and encourage the wildlife to flourish.
The area between the solar panels will be sown to grass, and grazed by sheep, providing a much improved wildlife habitat rather than the current arable field, in addition to the landscape planting of some 25,000 woodland trees will assist the creation of an improved biodiversity.
The open ditches created to restrict access, will also improve the surface water drainage, supporting the existing underground field drainage.
It would be good to have an understanding of the actual extent of public access (Asland Walk)
The website www.brethertonenergy.co.uk shows the detailed planting scheme and the exact width involved, but generally the access along the towpath will be widened to 8m from the canal bank to give more area for public access, with a further 11m wide landscaped planting strip for approximately half the length of the canal.
Likewise, along the westerly bank of the River Douglas, the footpath will be at least an 8m wide running along the top of the embankment, with woodland planting and a hedge to the west to limit direct views of the solar panels to the west when walking along the footpath.
A visitor “interpretation hut” will be placed at the northern end of Asland Walks. This will give full details of the sites history, live reporting of the energy being generated, and 360° views from the hub on the wind turbine giving views over the south west Lancashire plain.
I doubt the park would be an attractive place to visit
Part of the tree planting has recently been undertaken, it is now possible to envisage how the wide open space between the canal and the woodland planting will improve public access and the ambiance of the canal. This wide margin will be mown and maintained, both along the canal and riverbank giving space for public recreation. Whereas previously, the towpath and the footpath along the river bank was limited to almost single file access with the remaining field being intensively farmed.
In addition, a Visitor Interpretation Centre will allow visitors to see, learn and understand how electrical energy has and is being generated from the Asland Walks Energy Park together with 360 degree views from the potential 130m hub of the wind turbine.
