Key Takeaways
- A typical 2-3 person Costa del Sol apartment should pay €70-120/month averaged across the year. If you’re regularly outside this range, at least one correctable thing is wrong.
- Tariff type is the biggest lever. Being on a free-market (mercado libre) contract when PVPC would suit your usage pattern is worth €15-30/month — often more in summer.
- Potencia contratada is a standing charge regardless of usage. Each kilowatt you don’t need costs you €3-4/month in pure waste. Most apartments in Spain are over-contracted by 1-3 kW.
- Time-of-use pricing means when you run appliances matters as much as how much you run. Valle hours (typically 00:00-08:00 and weekends) can be 50-70% cheaper than punta hours on a discriminación horaria tariff.
- Bono social gives 25-65% off for qualifying households. If you are a pensioner, large family, or have a household income below the threshold, you may qualify and not know it.
- The quick audit takes 10 minutes. Your bill has four numbers that tell you almost everything: tariff type, potencia contratada, monthly kWh, and whether bono social is applied.

Spanish electricity bills are not transparent by design. They are formatted to satisfy regulatory requirements, not to help you understand what you’re paying or why. Most Costa del Sol residents pay their bills without reading them — and that’s exactly what energy companies depend on.
This guide gives you one thing: a benchmark. What should your bill actually be, for your household type, in your region, in 2026? And if you’re over that number, which specific thing is most likely causing it?
The Benchmarks (Costa del Sol, 2026)
These figures represent what households on reasonably optimised contracts should pay. They assume: correct tariff type for their usage pattern, appropriate potencia contratada, and no obvious inefficiencies. They are annual averages converted to monthly equivalents, with seasonal ranges noted.
1-2 person apartment, no regular AC use
Average: €50-75/month
This is a base-load household: lighting, refrigerator, washing machine, TV, laptop, occasional cooking. No air conditioning running regularly. Minimal pool or garden equipment. If you’re paying above €75/month consistently in this household type, something specific is driving the overage.
2-3 person apartment, AC in summer
Annual average: €70-120/month
Winter (November-April): €50-80/month
Summer (June-September): €120-180/month
This is the most common household type among Costa del Sol expat residents. The seasonal variation is significant — summer AC usage can double or triple electricity consumption compared to winter. The annual average smooths this out, but expect the summer months to be substantially higher.
3-4 person house, AC plus pool
Annual average: €100-200/month
Winter: €80-120/month
Summer: €180-280/month
Pool filtration pumps running 6-8 hours/day add €30-60/month depending on pump size and whether they’re on a timer or run continuously. AC across multiple rooms in summer is the dominant cost driver. The right tariff and potencia settings matter more at this household size — the stakes of getting it wrong are higher.
Villa with pool, AC, multiple units or annexes
Average: €150-300/month
Larger properties have more variables — number of units on a single meter, pool size, whether the property has heated zones or electric hot water. The range is wide because the household configurations vary too much to benchmark precisely. Use this as a rough orientation point; if you’re above €300/month outside peak summer, a specific audit is warranted.
What Actually Drives Your Bill
Spanish electricity bills have three main cost components. Understanding which one is oversized tells you where to focus.
Tariff type: PVPC vs mercado libre (€15-30/month difference)
PVPC (Precio Voluntario para el Pequeño Consumidor) is the regulated tariff, with prices set by the Spanish government and updated hourly based on wholesale market rates. It fluctuates significantly — the cheapest hours (typically early morning and weekends) can be 50-70% cheaper than peak hours.
Mercado libre (free market) contracts are offered by private energy companies at fixed or variable rates they set themselves, outside the regulatory pricing system. These are heavily marketed, often with introductory offers, and can be significantly more expensive than PVPC for households with flexible usage patterns.
The common assumption — that fixed-rate contracts are simpler and therefore better — is frequently wrong. For households that can shift discretionary usage (dishwasher, washing machine, EV charging) to valle hours, PVPC typically works out cheaper. For households with very inflexible usage patterns where everything runs during punta hours, a flat-rate mercado libre contract may be comparable.
The difference in practice: €15-30/month on an average apartment, potentially more in summer. This is purely a contract choice — no change in behaviour required to capture it, just switching tariffs.

Potencia contratada: the standing charge you may not need (€3-4/month per kW)
Potencia contratada is the maximum power capacity contracted with your distributor — the amount of electricity that can flow into your property simultaneously before the circuit breaker trips. It is measured in kilowatts (kW) and appears on your bill as a fixed daily charge regardless of how much electricity you use.
The charge structure: approximately €0.10-0.12/day per kW contracted. At 4.6 kW (a common residential setting), that’s roughly €0.46-0.55/day or €14-17/month before you’ve used a single watt of electricity. At 6.9 kW, it’s €21-25/month. At 10.35 kW (not unusual in some properties), it’s €31-37/month.
The key insight: you are paying for maximum capacity, not average usage. If your actual peak demand — all your appliances running simultaneously — never approaches your contracted level, you are paying for capacity you don’t use.
Most properties in Spain are over-contracted. The default setting when many properties were connected was higher than typical residential needs. Previous owners may have had specific equipment requirements that no longer apply. Changing potencia requires a request to your distributor and sometimes a technician visit, but it is straightforward. Dropping from 6.9 kW to 4.6 kW (if your usage supports it) saves approximately €7-10/month permanently.

Time-of-use behaviour: valle vs punta (50-70% price difference)
If you’re on a PVPC tariff with discriminación horaria (time-of-use pricing), electricity costs vary significantly by hour of day. The broad pattern:
- Valle (off-peak): Midnight to 8am daily, plus all day Saturday and Sunday. Approximately €0.05-0.12/kWh depending on market conditions.
- Punta (peak): 8am-10pm on weekdays. Can reach €0.25-0.40/kWh during high-demand periods.
The difference is not marginal — it can be 3-4x between cheapest and most expensive hours during volatile market periods. For large, shiftable loads (dishwasher, washing machine, pool pump timer, EV charging), the savings from running in valle rather than punta are meaningful. A washing machine cycle costs roughly €0.30-0.50 in punta and €0.08-0.15 in valle. A pool pump running 6 hours costs €0.60-1.20 in punta and €0.18-0.45 in valle.
For households that can make this shift — and most can, by using appliance timers — it translates to €20-50/month in savings depending on household size and what gets moved.

Bono social: 25-65% discount if you qualify
Bono social is a government discount on electricity for vulnerable households. The discount levels:
- 25% discount: Households at risk of energy poverty (income thresholds apply)
- 40% discount: Severely vulnerable households
- 65% discount: Critical severe vulnerability (serious illness, dependent family members)
Qualifying criteria include: household income below specified thresholds (adjusted for household size), large families, households where all members are unemployed, and households with a member who has a disability certificate above 33%.
The discount applies to the entire bill — both the energy consumption component and the potencia standing charge. For a household paying €100/month, bono social at the 25% level saves €25/month — €300/year. At 40%, it saves €40/month.
The problem: bono social must be applied for. It is not automatic. Your electricity company is not required to tell you that you qualify. If you meet the income criteria — which many Costa del Sol residents on pension income or modest fixed incomes do — you may have been qualifying for years without the discount applied.

The 10-Minute Audit
Get a recent electricity bill. You need four things from it:
1. Tariff type. Look for “tarifa” or “modalidad de tarifa.” It will say PVPC (or “tarifa regulada”) or name a commercial company’s tariff (Endesa One, Iberdrola Click, etc. = mercado libre). If it’s mercado libre, check the price per kWh you’re paying and compare to current PVPC rates.
2. Potencia contratada. Look for “potencia contratada” — it will be in kW (4.6, 5.75, 6.9, 10.35 are common residential levels). Calculate your actual likely peak demand: how many large appliances run simultaneously? If you’ve never tripped a circuit breaker, you may have more capacity than you need.
3. Monthly kWh consumption. Find the consumption in kWh for the billing period. Divide by the number of days and multiply by 30 for a monthly equivalent. Compare to the household benchmarks above: 200-350 kWh/month for a 1-2 person apartment without AC; 400-700 kWh/month for a 2-3 person apartment in summer with AC.
4. Whether bono social is applied. This will appear as “descuento bono social” if active. If it’s not shown and you might qualify based on income, investigate.
If your monthly cost sits above the benchmark range for your household type, at least one of these four items is the cause. The guides linked below explain how to fix each one.
The 4 Most Common Reasons You’re Over-Benchmark
1. Wrong tariff — mercado libre when PVPC would be cheaper
Free-market contracts are heavily marketed because energy companies make more margin on them. The introductory rate looks competitive. After 12 months, prices often increase. Meanwhile, PVPC — with time-of-use optimisation — frequently undercuts them for households with flexible usage. Check the price per kWh on your bill and compare to current PVPC rates (available on the CNMC website). If you’re paying materially more per kWh, switching back to PVPC costs nothing. → How to Switch
2. Too much potencia — paying for capacity you don’t use
If you’ve never tripped your circuit breaker and you’re not running industrial equipment, you may be over-contracted. Request a load analysis from your distributor or use an energy monitor for a week to track peak demand. If your peak demand is consistently 2-3 kW below your contracted level, reducing potencia is a low-effort permanent saving. → How to Reduce Potencia
3. Running appliances in punta hours
Washing machine at 10am, dishwasher after dinner, pool pump running 9am-3pm — all punta hours on weekdays. Shifting these to overnight or weekend running requires timer settings, not lifestyle changes. Most appliances have a timer function or delay-start feature. Use it. → Time-of-Use Guide
4. Missing bono social when you qualify
If your household income is below the qualifying threshold and you haven’t applied, you are leaving money on the table. The application process is handled through your electricity company and requires income documentation. It is worth the administrative effort for the discount level it delivers. → Bono Social Application Guide
Frequently Asked Questions
My bill looks higher in summer — is that normal?
Yes. Summer electricity costs are higher for two reinforcing reasons: AC usage increases consumption significantly, and PVPC wholesale prices tend to be higher in summer due to increased demand across Spain. A bill that doubles from January to July is not unusual for a household with AC. The benchmarks above account for this — the summer ranges reflect normal seasonal variation.
I’m on PVPC but my bills are still higher than the benchmark — why?
PVPC tariff is correct, but the other factors still apply. Check: potencia contratada (are you over-contracted?), time-of-use behaviour (are you running heavy appliances during punta?), and bono social eligibility. Also check whether your property has any unusual base loads — old refrigerators, water heaters running continuously, or poorly insulated spaces requiring more heating or cooling than a comparable property.
How do I know if PVPC or mercado libre is better for me?
The key variable is flexibility. If you can shift discretionary usage (laundry, dishwasher, pool pump, EV) to valle hours (midnight-8am and weekends), PVPC with discriminación horaria almost always wins. If everything in your household runs between 9am and 10pm on weekdays regardless of price signals, a flat-rate mercado libre contract may be comparable. The majority of households have enough shiftable load that PVPC + time-of-use optimisation outperforms mercado libre. → Full comparison
Can I reduce my potencia myself or does it require a technician?
You make the request to your electricity distributor (the grid company — Endesa Distribución, Iberdrola Distribución, etc. — not your billing company). They process the change administratively. Whether a technician visit is required depends on the size of the reduction and the current equipment. Small reductions (e.g. 6.9 kW to 5.75 kW) are sometimes done remotely on smart meters. Larger reductions may require a visit. There is typically no fee for reducing potencia (there may be a fee for increasing it). → Full guide
I have a pool — the benchmarks seem high. Is the pool really that significant?
Pool filtration pumps are significant. A typical 0.75 kW pump running 8 hours/day costs approximately €1.80-4.00/day depending on electricity prices, or €54-120/month. Reducing filtration run time, installing a variable-speed pump, or running the pump exclusively in valle hours (on a timer) can reduce pool-related electricity costs by 40-60%. Many pool owners are over-filtering — especially in the off-season when biological load is lower. → Summer electricity costs guide
My electricity company says the bill is correct — why does this guide say I might be overpaying?
The bill is almost certainly arithmetically correct — the company is applying your tariff and potencia charge accurately. The issue isn’t billing errors; it’s suboptimal contract settings. You could be on the right tariff for someone, just not the right one for you. Your potencia could be correctly charged at 6.9 kW — you just might not need 6.9 kW. The electricity company’s job is to bill you correctly for what you contracted, not to optimise your contract. That job belongs to you. → Common contract traps to avoid

Frequently Asked Questions
How much does electricity cost in Spain?
The average Spanish household pays EUR 80-150 per month for electricity. On the Costa del Sol, summer bills can spike to EUR 200+ due to air conditioning. The regulated PVPC tariff averages EUR 0.10-0.20 per kWh depending on the time of day.
What is the PVPC tariff in Spain?
The PVPC (Precio Voluntario para el Pequeno Consumidor) is the regulated electricity tariff with hourly pricing that varies throughout the day. It is cheaper during off-peak hours (midnight to 8am) and most expensive during peak hours (10am-2pm and 6pm-10pm).
Should I choose PVPC or a fixed-rate tariff?
PVPC works well if you can shift consumption to off-peak hours (running dishwashers and washing machines at night). Fixed-rate tariffs offer budget predictability but are typically 10-20% more expensive overall. For most expats new to Spain, a fixed rate reduces bill shock.
How do I switch electricity provider in Spain?
Contact your chosen new provider with your CUPS code (on any bill) and they handle the switch. It takes approximately 2 weeks. There are no switching fees or penalties. Your supply is never interrupted during the change.
What is the potencia contratada?
The potencia contratada is your contracted power capacity in kW. Most homes have 3.45-5.75 kW. If your appliances exceed this, the breaker trips. You can adjust it through your provider but higher capacity means a higher fixed daily charge.
