Sri Lanka’s 🇱🇰 18% Electricity Tariff Hike: Looks Simple, but a Fundamental Shift
180 units → Rs.6,584.62
181 units → Rs.8,666.67
Gap → Rs.2,082.05
⭕ From May 11, PUCSL approved an 18% electricity tariff hike for domestic users consuming above 180 units per month.
⭕ Households using 0–180 units will not face an increase, after the Government agreed to cover Rs.15 billion of the Rs.38 billion revenue gap.
⭕ The visible change looks simple, but the deeper change is structural: With this revision Sri Lanka 🇱🇰 has effectively added a new tariff threshold above 180 units.
⭕ Earlier, domestic electricity pricing mainly worked around two consumption groups: below 60 units and above 60 units.
⭕ For years, policy assumed households using below 60 units were more likely to be low-income consumers needing subsidized rates.
⭕ Below 60 units, users paid lower slab rates: the first 30 units at one subsidized rate, and units 31–60 at a slightly higher rate.
⭕ But once usage crossed 60 units, the first 60 units were treated as one higher-priced block, creating a sharp bill jump from 60 to 61 units.
⭕ 60 units -> Rs.646, 61 units -> Rs.1,292.31, nearly doubling the bill with just one extra unit.
⭕ In simple terms, a household using 60 units paid one bill, while 61 units triggered a much higher bill because the tariff category changed.
⭕ The new revision creates a similar cliff at 180 units, effectively adding a third major domestic tariff tier.
⭕ Up to 180 units, bills are still calculated through slabs: 0–60, 61–90, 91–120, and 121–180 units.
⭕ Above 180 units, the billing method changes: the first 180 units are charged at Rs.32.50 per unit, and each additional unit is charged at Rs.100.
⭕ This means the real impact is not only the 18% hike, but also the creation of a new high-consumption threshold at 180 units.
⭕ That is why this tariff revision is different: it changes both the price level and the structure of how domestic electricity bills are calculated.
⭕ For households consuming around 180 units, staying below 181 units is critical, because one extra unit can add about Rs.2,082 to the monthly bill.

3This is how the Malimawa reduces electricity tariffs by 33%
Wouldn’t this price hike affect everyone ultimately? - It says that government bear a percentage. Subsidy. But how government actually beat that cost? Mainly taxes. We can assume that most of the tax payers would be in that 180 units range, or at least closer to it. So there’s the hike which would affect directly, and there’s taxes which they indirectly pay for the subsidized portion. - Also, this price hike would be passed onto the general public as a price hike on consumer items. Not simple as it seems. 🤷♂️
