How to Use the EWA Bill Calculator
Understanding Your EWA Bill in Bahrain
The Electricity and Water Authority (EWA) is Bahrain's sole utility provider, supplying electricity and water to all residential, commercial, and industrial customers. EWA issues monthly invoices that include separate charges for electricity, water, and municipality fees.
How the tiered system works: EWA uses a progressive tariff — the more you consume, the higher the rate per unit. For electricity, Bahraini domestic customers pay just 0.003 BD/kWh for the first 3,000 kWh (equivalent to about 9 BD). However, if consumption exceeds 7,000 kWh, the highest tier rate of 0.032 BD/kWh applies to all units above that threshold. This design encourages energy conservation.
Typical household consumption: A standard Bahraini home with air conditioning typically uses 1,500–4,000 kWh/month for electricity and 15–40 m³/month for water. During summer months (May–September), electricity bills can double due to heavy air conditioning use.
Direct debit: EWA customers can set up automatic bank deduction (direct debit) to avoid missed payments and late fees. You can manage this through the EWA website at www.ewa.bh or by calling 17515555.
💡 Tips to Reduce Your EWA Bill
- Set air conditioners to 24–26°C — each degree cooler adds approximately 6–10% to your electricity bill.
- Use inverter-type air conditioners which are up to 40% more efficient than conventional models.
- Switch to LED lighting — LEDs use 75% less energy than incandescent bulbs.
- Fix water leaks immediately — even a slowly dripping tap can waste several cubic metres per month, pushing you into higher water tariff tiers.
- Run washing machines and dishwashers with full loads and during off-peak hours.
- Install solar water heaters — eligible for EWA's net metering programme which can reduce or eliminate water heating costs.
- Keep fridge and freezer coils clean and ensure doors seal properly — faulty seals increase energy consumption by up to 25%.
Frequently Asked Questions
How does EWA calculate my electricity bill in Bahrain?
EWA uses a tiered (block) tariff system for Bahraini domestic accounts. The first 3,000 kWh cost 0.003 BD/kWh, units 3,001–5,000 cost 0.009 BD/kWh, units 5,001–7,000 cost 0.016 BD/kWh, and any usage above 7,000 kWh costs 0.032 BD/kWh. A 1 BD administration fee is added to the electricity sub-total.
What are the EWA water rates for Bahraini households?
For subsidized Bahraini accounts: the first 60 m³ costs 0.025 BD/m³, usage of 61–100 m³ costs 0.080 BD/m³, and consumption above 100 m³ costs 0.775 BD/m³. A 1 BD administration fee is added to the water sub-total.
What are municipality fees on my EWA bill?
Municipality fees are charged separately and are typically calculated as a percentage of your electricity and water usage. The exact rate depends on your property type and location. This calculator estimates them at approximately 15% of your electricity sub-total.
Are the rates different for expatriates and non-Bahrainis?
Yes. Non-Bahraini / expatriate residents are on unsubsidized tariffs with higher rates. This calculator provides both subsidized (Bahraini) and expatriate rate tiers so you can estimate your bill accurately.
How do I read my EWA electricity meter?
Your EWA bill shows both the current and previous meter readings in kWh. The consumption for the billing period = Current Reading − Previous Reading. You can enter these values directly into this calculator using the "By Meter Reading" mode.
What is the EWA billing cycle?
EWA issues monthly bills. The billing date and due date are shown on each invoice. Direct debit customers have their bills automatically deducted on the due date. You can pay via EWA website, EWA app, banks, or the 17515555 hotline.
Why is my EWA bill higher than expected?
Common reasons include: increased consumption from air conditioning in summer, water heaters, pool pumps, or appliances. If your consumption exceeds 3,000 kWh/month you move into higher tariff tiers which significantly increases the bill. Water leaks can also cause unexpectedly high water bills.
How do I contact EWA Bahrain?
