An energy facility rarely appears in a property listing, but it can change the surroundings and the questions worth asking before you buy. Hogarfax has expanded its former nuclear check: it now cross-checks each plot with 8,643 BTN25 energy points —wind farms, substations, solar, hydropower, thermal and combined-cycle plants, fuel-extraction sites and nuclear power plants— and shows the category, name and distance.
Which energy facilities may be nearby
The catalogue includes electrical substations, photovoltaic plants, wind farms, hydropower plants, fuel-extraction sites, thermal plants, solar-thermal plants, combined-cycle plants and nuclear power plants. They do not all mean the same thing: a substation may mean visible infrastructure, a wind farm may affect landscape and perceived noise, and a nuclear plant has a specific emergency-planning context.
The category is a starting point, not a diagnosis. A mapped point does not prove a specific nuisance or safety issue. It tells you what to investigate: the facility's scale, activity, projects, access, landscape and how the local market experiences it.
Distance matters, but it is not the whole story
The report measures the distance from the plot to the mapped point. That is useful for finding facilities a listing may omit, but it is not a measurement of noise, emissions, safety or property value. The context depends on the category, size, physical barriers, current projects and the experience of the surroundings.
The emergency zones: 10 km and 30 km
Spain's nuclear emergency plans (PLABEN and each plant's own plan) define two rings around every site. Zone I extends up to 10 km and is the urgent protective-action area (sheltering, evacuation). Zone II reaches 30 km, where longer-range measures are planned, such as stable-iodine prophylaxis to protect the thyroid.
Is it dangerous to live near a nuclear power plant?
For a nuclear plant, the relevant additional context is the official emergency-planning framework. Zone I reaches 10 km and Zone II reaches 30 km in the planning model described by Spanish emergency plans. These zones do not mean day-to-day danger; they describe preparedness and response measures.
The real reason a buyer should keep it in mind is not the everyday risk, but three concrete things:
- Emergency planning: if the home is in Zone I or II, it is worth knowing the plan and the measures foreseen.
- Perception and value: part of the market discounts proximity to a plant, regardless of the safety data.
- Shutdown horizon: decommissioning a plant is a long process that changes local employment and activity.
What Hogarfax checks
The expanded "Surroundings and nuisances" check uses the BTN25 energy catalogue. If it finds one point, it shows the relevant category, name and distance. If several are nearby, it says Several nearby energy facilities and lists the detected types, so a more relevant facility is not hidden behind the nearest one. For nuclear sites, also consult the official emergency-planning zones and CSN information.
What to ask before buying
Search the report for the facility's name and category, open the viewer and check the distance. Ask about projects, extensions, noise, traffic, lighting and local perception according to the type. If it is nuclear, consult the municipality's emergency information and the official CSN and Civil Protection guidance.
Check wind, solar, thermal, combined-cycle and nuclear facilities near a home, using its exact location, category and distance.
