KSEB Bill Calculator (Kerala)

अपने Kerala बिजली बिल का अनुमान लगाएं

Estimate your KSEB electricity bill for Kerala. KSEB bills domestic consumers bi-monthly but assesses slabs on the monthly average (units ÷ 2). Below 250 units/month the tariff is telescopic; cross 250 and Kerala's well-known non-telescopic cliff kicks in.

bi-monthly नियम

KSEB bi-monthly बिल करता है। आप जो यूनिट डालते हैं वह आपकी पूरी ~60-day बिलिंग अवधि दर्शाती है — किसी एक महीने की नहीं। मासिक आंकड़े से तुलना के लिए, हम कुल को 2 से भाग देते हैं, जो आपके परिणाम में मासिक-समतुल्य के रूप में दिखता है।

The 250-unit non-telescopic cliff

≤250 units/month avg

Telescopic (slab-wise)

>250 units/month avg

Flat rate on ALL units

Cross a monthly average of 250 units and KSEB switches your entire bi-monthly consumption to a single higher non-telescopic rate — not just the units above 250. This is the single most misunderstood rule on a KSEB bill.

आम KSEB बिल ट्रैप

The 250-unit cliff is the single biggest trap

Below a 250 units/month average, KSEB charges telescopically. The moment your average crosses 250, your entire bi-monthly consumption is re-billed at a single higher non-telescopic rate — not just the units above 250. This calculator only models the telescopic range and is not accurate above it.

Bi-monthly bill, monthly-average trigger

Because the 250-unit threshold is assessed on your monthly average (bi-monthly total ÷ 2), a 501-unit bi-monthly bill crosses the cliff even though “501” doesn't look close to “250” at first glance.

Fixed charge depends on phase

KSEB's fixed charge is ₹80 for single-phase and ₹220 for three-phase connections per bi-monthly cycle — a similar structure to Tamil Nadu's, but at different amounts.

KSEB बिल कैसे कैलकुलेट होता है

The 250-unit non-telescopic cliff

Up to 250 units a month, each slab is charged at its own rate (telescopic). The moment your monthly average crosses 250 units, KSEB re-bills your entire consumption at a single higher non-telescopic rate — so 251 units can cost noticeably more than 250. This calculator models the telescopic range only and is not accurate above 250 units/month.

Bi-monthly billing, monthly assessment

Bills arrive every two months, but the slab thresholds are applied to the monthly average. Enter your two-month units here; the calculator uses bi-monthly slab widths (twice the monthly figures) and shows a monthly-equivalent total.

Telescopic slabs and fixed charge

Monthly telescopic rates run ₹3.35 (0–50), ₹4.25 (51–100), ₹5.35 (101–150), ₹7.20 (151–200) and ₹8.50 (201–250), plus a fixed charge of ₹40/month single-phase and 5% electricity duty.

आपका बिल, हिस्सा दर हिस्सा

ऊपर दिए गए 300-यूनिट उदाहरण पर आधारित। हर लाइन का मतलब जानने और उसे प्रभावित कर सकते हैं या नहीं, यह जानने के लिए उसे खोलें।

Energy chargeReducible₹1,295.00+

Priced across telescopic slabs — the more you use, the higher the marginal rate. Shifting usage below your next slab threshold lowers this line directly. This example totals ₹1,295.00.

Fuel cost adjustment (FCA)Set by DISCOM₹0.00+

A ₹0/unit pass-through surcharge that tracks the DISCOM's power-purchase cost. It applies equally to every consumer on this tariff and isn't something you can reduce by changing usage.

Fixed chargeFixed₹80.00+

Charged regardless of how many units you use (single-phase). The only way to change this line is to change your phase, sanctioned load, or connection type.

Electricity dutyStatutory₹64.75+

A 5% state government levy on the energy charge — set by statute, not by the DISCOM, and not reducible by usage pattern.

अपना मीटर कैसे पढ़ें

डिजिटल मीटर LCD डिस्प्ले पर kWh ("यूनिट") में कुल रीडिंग दिखाते हैं — दशमलव बिंदु से पहले की संख्या नोट करें। किसी बिलिंग अवधि की खपत जानने के लिए, अपनी मौजूदा रीडिंग में से पिछली रीडिंग घटाएं — ऊपर कैलकुलेटर का "मीटर रीडिंग" मोड ठीक यही काम करता है। एनालॉग मीटर में डायल गेज होते हैं जिन्हें बाएं से दाएं पढ़ा जाता है — हर डायल पर सुई जिस संख्या को अभी पार कर चुकी है उसे नोट करें।

अपना KSEB बिल कम करने के तरीके

  • जहां संभव हो, अपनी खपत अगले स्लैब की सीमा से नीचे रखें — ₹8.50/यूनिट से ऊपर की यूनिट सबसे महंगी पड़ती हैं।
  • ज़्यादा खपत वाले घरों के लिए, रूफटॉप सोलर आपकी सबसे महंगी टॉप-स्लैब यूनिट की भरपाई कर सकता है — ऊपर सोलर सेक्शन देखें।

नेट मीटरिंग समझाया गया

नेट मीटरिंग से रूफटॉप सोलर सिस्टम अतिरिक्त बिजली आपके मौजूदा मीटर के ज़रिए वापस ग्रिड में भेज सकता है, जो उल्टा चलता है। बिलिंग के समय, आपका डिस्कॉम भेजी गई यूनिट को आपके द्वारा ग्रिड से ली गई यूनिट के बदले क्रेडिट करता है — आपसे सिर्फ नेट अंतर का बिल लिया जाता है। टेलीस्कोपिक स्लैब के साथ, यह आमतौर पर आपकी सबसे महंगी यूनिट की भरपाई पहले करता है। अपना सोलर पेबैक अनुमान लगाएं →

KSEB के बारे में

The Kerala State Electricity Board (KSEB) began functioning on 31 March 1957. Under the Electricity Act 2003, it was converted into a company — Kerala State Electricity Board Limited (KSEBL) — incorporated on 14 January 2011 and operating independently from 1 November 2013. “KSEB” remains the name most commonly used for bills and customer service.

KSEB distributes power across nearly all of Kerala, with a few exceptions: the Thrissur Municipal Corporation area, the Munnar (Kannan Devan Hills) area, and several small industrial-park zones are served by separate, smaller licensees.

Does KSEB supply electricity to Kochi and Thiruvananthapuram?

Yes — KSEB covers both Kochi and Thiruvananthapuram (Trivandrum) along with the rest of Kerala. The notable exceptions are the Thrissur Municipal Corporation area and Munnar (Kannan Devan Hills), which have their own separate distribution licensees.

अक्सर पूछे जाने वाले सवाल

What is the 250-unit rule in Kerala?

Below 250 units/month KSEB charges telescopically (each slab at its own rate). Above 250 units/month it switches to non-telescopic — your whole consumption is billed at one higher rate, which this calculator does not model.

KSEB bills me every two months — how do slabs work?

Slabs are assessed on the monthly average, i.e. your two-month units ÷ 2. The calculator uses bi-monthly slab widths and shows a monthly-equivalent figure.

Why might my real KSEB bill differ above 250 units?

Because the non-telescopic regime above 250 units/month re-prices your entire usage at a single higher rate. Treat estimates above 500 bi-monthly units as indicative only.

Is there an electricity duty in Kerala?

Yes, a 5% electricity duty applies on the energy charge, along with a per-month fixed charge billed bi-monthly.

Does KSEB supply electricity to all of Kerala?

Almost all — KSEB Limited (KSEBL) covers the entire state except the Thrissur Municipal Corporation area, the Munnar (Kannan Devan Hills) area, and a handful of small industrial-park licensees, which have their own separate distribution licensees.

How do I check or pay my KSEB bill online?

Pay via the official KSEB Web Self Service portal at wss.kseb.in, or the KSEB Mobile App. For queries or outages, call the 24×7 helpline 1912 or 0471-2555544.

What's the difference between KSEB and KSEB Limited (KSEBL)?

The original Kerala State Electricity Board (KSEB), formed in 1957, was converted into a company — Kerala State Electricity Board Limited (KSEBL) — incorporated in January 2011 and operational from 1 November 2013. "KSEB" is still the everyday name people use.
