Distributor vs Retailer: Who Owns the Meter

In an electricity supply chain, the company that owns and operates the local distribution network is not the company that sells the energy. The distributor maintains the poles, wires, transformers and the meter, and it is the party that responds when supply fails at the connection. The retailer, by contrast, buys energy in the wholesale market and bills the household or small business under a contract. The distinction is often described in Spanish-speaking markets as the difference between distributor and retailer, and it decides who answers which question.

What is the difference between the distributor and the retailer?

The distributor holds the concession or licence for a geographic area. It builds and maintains the low-voltage and medium-voltage network, operates substations, restores faults, and installs or replaces the meter at the service point. It does not choose the price per kilowatt-hour that a household pays, and it does not send the commercial bill. Its revenue comes from regulated network charges, sometimes called tolls or peajes, which are set by the regulator and passed through to consumers.

The retailer, sometimes called the comercializadora, is the commercial counterparty. It buys energy on the wholesale market, sets the retail tariff or applies a regulated one, issues the invoice, and handles contract changes, tariff switches and payment arrangements. A household can change retailer without any physical work on the network, because the wires and the meter stay with the distributor.

This split has a practical consequence. A billing question goes to the retailer. A supply failure, a damaged meter, a burnt cable or a new connection goes to the distributor. Confusing the two is the most common reason a complaint is sent to the wrong office and loses time.

How do you find which distributor covers your address and who to call?

The distributor is tied to the address, not to the customer. Moving house does not change the network company; changing retailer does not change it either. To identify the distributor for a specific address, the usual route is to look at the supply contract or the bill, which normally names the distributor in a dedicated field, or to use the distributor lookup tool published by the national regulator or by the local distributor itself. The address, the postal code and sometimes the CUPS code, the unique supply point identifier, are enough to return the name.

Once the distributor is known, the contact route for faults is the distributor's 24-hour emergency line, not the retailer's customer service. Distributors publish a free fault number, and calls about a live cable, a fallen line or a total outage should go there. The retailer is the right contact for a wrong invoice, a tariff change, a contract cancellation or a payment plan.

For a household or small business, the practical rule is to keep two numbers: the retailer for commercial matters and the distributor for anything physical on the network. The regulator in Spain, the CNMC, publishes consumer material on this division, and the local guide for the L'Ampolla area describes the same split for Spanish households and small shops.

How does the smart meter work and how are readings taken?

A smart meter, or contador inteligente, records consumption in intervals, commonly every hour or every fifteen minutes, and stores the data locally. It can be read remotely over the distribution network, so in most cases no one visits the property. The distributor owns the meter and is responsible for its readings and for sending the measured values to the retailer, which then applies the tariff and issues the bill.

The meter also supports remote operations: switching between tariff periods, limiting contracted power, and in some cases connecting or disconnecting supply. The customer does not normally read the meter, but can check the display to compare the consumption shown with the consumption billed. When a reading looks wrong, the first step is to compare the meter display with the invoice period, and then to raise the discrepancy with the retailer, which forwards the case to the distributor if the meter or the reading is at fault.

Estimated readings still occur when remote communication fails. In that case the bill may be based on an estimate, and a later reading corrects the difference. This is a normal part of the process, not evidence of a fault.

Who is called when the supply fails?

A supply failure is a network event, so the distributor is the party called. The distributor operates the fault centre, dispatches crews, and restores service. The retailer has no crew and cannot repair the line, although it can inform the customer about the status of the supply point.

The distinction matters for timing. The distributor's obligation is to restore supply within the timeframes set by regulation, and those timeframes are measured from the moment the fault is reported to the distributor. A call to the retailer first can delay the clock. For a partial failure, such as one room losing power while the rest of the property works, the cause may be inside the installation, and an electrician is the right contact rather than the distributor.

How does a complaint escalate?

The first step is the retailer's customer service, which must issue a reference number and respond within the period set by consumer rules. If the answer is unsatisfactory or absent, the next step is the distributor, when the issue concerns the meter, the reading or the network. Both companies are required to have a written complaints channel.

If the two companies do not resolve the case, the consumer can turn to the regional consumer authority or to the CNMC for matters within its competence, such as billing disputes and supply quality. The claim normally needs the invoice, the contract, the CUPS code and the reference numbers from the earlier steps. The CNMC publishes the routes and the deadlines, and the same structure applies to households and small businesses.

A parallel route exists for social matters. The bono social, the discounted tariff for eligible consumers, is requested through the retailer, while the eligibility conditions are set by regulation. For self-consumption with surplus, the meter must be adapted and the surplus is settled through the retailer, again with the distributor responsible for the physical installation.

What a household or small business should keep on file

The practical file is short: the contract with the retailer, the last invoice, the CUPS code, the name of the distributor, the distributor's fault number and the retailer's complaints reference. With those items, a household or a small shop can route each question to the correct company without repeating the case.

The division is stable: the distributor owns the network and the meter, the retailer sells the energy and issues the bill. Reading the bill line by line shows which charges belong to the network and which belong to the energy supply, and that reading is the fastest way to know which company to call.
