Finding a Grid Reference
A clear grid reference is often the quickest way to identify the correct site location for feasibility work, wind and hydro resource checks, surveys, planning review, and grid connection discussions.
Why Grid References Matter
A site may be known by a farm name or postcode, but that does not always identify the actual point that matters for a renewable energy project.
In rural areas especially, a postcode may point to a farmhouse, a road entrance, or a general area rather than the precise location of a turbine, hydro intake, powerhouse, switchroom, or proposed PV installation.
A grid reference gives a much clearer way to identify the site on a map. That helps with early feasibility review, technical discussions, access planning, and wider project development.
It is also useful where site-specific data needs to be checked. For example, wind resource tools such as the archived NOABL database rely on accurate location input, and hydro and grid connection work also benefit from identifying the correct point on the site from the outset.
Using Streetmap
Streetmap remains one of the simplest ways to find a grid reference because it allows you to search a location and use the convert function directly from the map view.
For early-stage renewable energy work, Streetmap is useful because it provides a straightforward route from a place name or postcode to an Ordnance Survey grid reference. That makes it practical for site feasibility work, preliminary wind speed checks, hydro site review, and early grid connection discussions.
The key is to work through the map carefully and make sure the point you convert is the point that actually matters for the project.
Step 1: Open Streetmap and search using a postcode, place name, or nearby village to get into the correct area.
Step 2: Zoom in until you can clearly identify the site, building, field, access point, or installation area.
Step 3: Move the arrow to the actual location of the point you are trying to identify.
Step 4: Use the Streetmap convert function to obtain a full list of different grid location identifiers.
Step 5: Cross-check the location against surrounding landmarks, aerial imagery, or site photos before recording it. We always drop the lat and long coordinates into google earth and check against the satallite background.
Streetmap is especially useful at this stage because the convert function is easy to access and gives a quick way to move from a map point to a usable grid reference.
A Practical Sequence
The best grid reference is usually the one tied to the actual part of the site that matters for the project.
This approach keeps the process simple while still improving accuracy. For many projects, that is enough to support an initial review and to avoid confusion later when the site is discussed in more technical detail.
What Point Should You Reference?
The best reference point depends on the technology and what the grid reference is going to be used for.
On some projects it is sensible to keep more than one grid reference. A wind project may need the turbine position, while a hydro project may need separate references for the intake and powerhouse. Likewise, a grid connection discussion may focus on the electrical supply location rather than the centre of the site.
Using the right point from the beginning makes technical review clearer and reduces the chance of working from the wrong location later.
Mistakes to Avoid
Small location errors can create confusion in feasibility work, resource checks, and engineering discussions.
A common mistake is using only the postcode when the actual installation is some distance away. Another is taking the site entrance as the project location even though the turbine, intake, or PV building lies elsewhere on the holding.
It is also easy to record a reference without checking that the selected point still makes sense when viewed against the wider area. A quick check against an aerial image or site photo can prevent this.
Where the project has several important locations, it is often better to provide more than one grid reference with a clear description of what each point relates to.
What to Send Us
A small amount of clear location information can make early project review much more efficient.
Grid reference: The main point relevant to the proposed project.
Address or postcode: Useful as supporting location information.
Photographs: Site photos help confirm the practical position and context.
Project description: A brief note on whether the enquiry relates to solar, wind, hydro, battery storage, or grid connection.
Additional points: Include more than one grid reference where the project has multiple key locations.
Accurate grid referencing is particularly useful where later review may include wind resource checks, preliminary hydro assessment, or early-stage grid connection appraisal.
Understanding Site Potential
Once you have a reliable grid reference, the next step is to assess how the site behaves and what energy resource may be available.
