Grid Connection Application
Getting permission to grid connect is a key risk to any wind project and the only way to really know is to apply for a formal offer to grid connect.
Once we have made the formal application we actively engage with the Distribution Network Operator (DNO) to find the most cost-effective grid connection method. It can take up to 65 working-days to get a formal offer from a DNO, though some are quicker. We will always do our best to expedite things.
Once an offer is received we can advise whether it is reasonable, and if appropriate, recommend steps that could be taken to reduce the overall costs. We are familiar with low voltage, 11 kV and 33 kV grid connections.
Should high risk issues be identified in the Initial Expert Overview, Scale Assessment or Planning, Technical & Financial Feasibility Study there may be ways of mitigating the risk by completing optional details studies on those issues.
- Wind Speed Modelling – We use the UK Met Office Virtual Met Mast service to improve the accuracy of initial wind speed assessment. This may be considered should the initial wind speed estimate of the site results in borderline financial return on investment.
- Noise Measurement Campaign – Should the developable area on your property be highly constrained due to turbine noise setbacks using the simplified ETSU-R-97 assessment method used in the feasibility assessment, it may be possible to position a wind turbine closer to properties if background noise is present at levels that allow turbines to be positions closer to properties. We can complete a background noise measurement assessment with our independent partners to try and overcome noise constrained wind turbine sites.
- Cumulative Noise Assessment – If there are other wind turbines fairly nearby your proposed site, cumulative noise may become an issue during the planning stage. We can model cumulative noise impact for your development and comment as to the possible impact of cumulative noise during a planning application.
- Turbine Manufacturer Consultation – If your site has an unusual layout, or presents other risks to siting a wind turbine from a technical perspective, we may need to consult with wind turbine manufacturers in order to assess whether they consider the site to be suitable for their turbine. An example of this would be a site layout that is likely to result in significant turbulence.
- Aviation Consultation – If the feasibility assessment identifies that the proposed wind turbine location presents a high risk to aviation, we may be able to overcome the issue by commissioning an independent aviation assessment with one of our partners and undertake consultation with the relevent aviation authority. The type of assessment would depend on the risk identified and the proximity of the wind turbine.
- Initial Geological Assessment – Some sites have surface or geological deposits present that can greatly increase the cost of a wind turbine project due to difficult foundation requirements. We can complete an initial desk based geolocial and surface deposit assessment to determine whether there this is a risk to your project.
- Flood Risk Assessment – If your site is at a low elevation, and possibly in a flood risk area, the cost of a wind turbine project may be greatly increased due to the need for flood protection. If you are concerned about possible flood risk we can provide a flood risk assessment for your development.
- Communications Provider Consultations – If the feasibility process identified objections by coimmunication service providers to siting a wind turbine near a communication link we can model the impact and consult with the link provider to try and overcome their objection. Objections are often based on a cautious view to the risk of interference with communication equipment and can often be overcome by further modelling and consultation.
Want to install a wind turbine?
If you are in the UK then take our Wind Site Self-Assessment - The first step to provide information we need to complete a Windpower Feasibility Study. It takes about 20 minutes to work through the basic checks, including:
- Estimating wind speed
- Checking proximity of nearby properties
- Checking site access and approach roads
- Investigating connection with the grid
