Connecting a rural plot to the electricity grid

Living off-grid with generators, batteries and bottled gas

About this topic
It is for anyone considering, planning or carrying out a move to Spain. You will come away understanding what rural water and power really involve and how to plan for them.
Start with "Wells (pozos), water rights and legal rural water in Spain". It shows whether a well is legal and usable for a home, which shapes every other choice about water. Then read the pages on water by tanker, grid connection costs and off-grid power, in whatever order fits your plot.
Buying a property and solar grants are not covered here.
Key rules
- Small well limit: A landowner can take up to 7,000 m3 per year from a well on their own land without a concession, but the well must still be registered with the basin authority.
- Water testing: Test well water at an accredited lab before drinking it, at least once a year and after floods.
- Tank size: Hold at least 7 to 15 days of use, or one full delivery plus a reserve.
- Drinking water: Ask for potable-certified water and a potability certificate, because some tankers carry non-potable irrigation water.
- Who pays: You pay for the extension works and regulated charges, and the distributor owns the lines afterwards.
- Budget first: Get a distributor quote and two or three installer quotes before you buy the plot.
Rural and off-grid supplies: the whole process, step by step
-
Check whether a well on the plot is legal and usable (Wells, water rights and legal rural water): Before you commit to the plot or plan any other water supply
-
Ask the electricity distributor for connection conditions (Connecting a rural plot to the electricity grid): As early as possible, because a simple connection takes a few weeks to a few months
-
Size your storage tank for 7 to 15 days of use, or one full delivery plus a reserve (Water by tanker, cisterns and storage tanks): Before you buy the tank or order the first delivery
-
Confirm hose length, truck weight limits and water source with the tanker supplier (Water by tanker, cisterns and storage tanks): Before ordering the first load
-
Order a tanker delivery by phone or WhatsApp (Water by tanker, cisterns and storage tanks): 1 to 3 days ahead, and longer in summer or drought
-
Complete the grid extension if the plot needs one, with project, regional approval and easements (Connecting a rural plot to the electricity grid): Can take many months or more than a year
-
Set up generators, batteries and bottled gas for the gap before the grid arrives, or for permanent off-grid life (Living off-grid with generators, batteries and bottled gas): Before you move in, and keep it as your backup after connection
