Indonesia’s Ministry of Energy and Mineral Resources (ESDM) confirmed on 2 September 2026 that electricity tariffs for all 13 non-subsidized and 24 subsidized customer tiers will stay frozen through the third quarter of the year, according to Archyde, citing Kompas and Minister Bahlil Lahadalia. That makes three consecutive quarters — Q1, Q2, and now Q3 2026 — in which the government has set aside the formula it wrote in 2024 specifically to make tariffs predictable, and building owners who budgeted off that formula have been wrong every time.

What did Jakarta just confirm, and what does it override?

Ministerial Regulation No. 7 of 2024, issued by ESDM, was built to depoliticize Indonesian electricity pricing: every quarter, a fixed formula recalculates non-subsidized tariffs from four inputs — the rupiah’s exchange rate, the Indonesian Crude Price (ICP), inflation, and the coal benchmark price (Harga Batubara Acuan, or HBA). For Q3 2026, the inputs evaluated over the February–April window were a rupiah near Rp 16,959.32 to the US dollar, ICP at US$96.12 a barrel, inflation of 0.21%, and an HBA of US$70 a ton, according to Archyde’s report of the ESDM data. Crude near US$96 and a rupiah sitting close to historic lows are exactly the conditions the formula exists to price in. The government applied none of it, holding rates flat instead — the same choice it made for Q1 and Q2, according to SolarQuarter and Petromindo’s reporting on those earlier decisions.

The tariffs that stayed put are the ones commercial buildings actually pay: Business B-3/TM (medium-voltage, the class most office towers and malls sit in) and Industrial I-3/TM both hold at Rp 1,114.74 per kWh, while smaller low-voltage business accounts (B-2/TR) stay at Rp 1,444.70 per kWh.

How predictable was the formula supposed to be?

The entire pitch of Regulation No. 7 of 2024 was that a mathematical, quarterly-reviewed formula would replace discretionary rate-setting with something a finance team could model. That is the opposite of what has happened. Three times running, the government has invoked its own override authority within the same regulation — citing, each time, the need to protect “consumer purchasing power and national economic stability,” per Minister Bahlil’s statements as reported by Archyde and SolarQuarter — rather than let the calculated output through.

A rules-based mechanism that gets suspended on the same policy grounds every single time it runs is not a rules-based mechanism. It is a discretionary one with a formula attached for show. For a facilities or finance team in Jakarta, Surabaya, or Bandung, the practical forecasting tool is not the regulation’s equation — it is Minister Bahlil’s quarterly announcement.

What does discretion actually cost a building budget?

In the short run, the freeze is a subsidy: buildings on B-3/TM and I-3/TM meters are paying below what the formula’s own inputs would have produced, given elevated crude and a weaker rupiah. That looks like relief. It is also, structurally, deferred risk. Nothing in the reporting on any of the three overrides describes a mechanism — comparable to the earmarked subsidy fund Malaysia used to soften its Automatic Fuel Adjustment surcharge before that fund ran dry in September — that is absorbing the gap between the formula’s calculated rate and the frozen one. Someone is carrying that difference: PLN’s own margins, the state budget, or a future correction that lands all at once instead of in three smooth quarterly steps.

Indonesia’s business tariffs already sit well below regional peers: at Rp 1,444.70/kWh, its B-2/TR rate compares to roughly Rp 1,636/kWh in the Philippines, Rp 1,735/kWh in Malaysia, Rp 1,943/kWh in Vietnam, and Rp 2,110/kWh in Singapore, based on comparative data compiled by Katadata’s Databoks. That gap is a real cost advantage today. It is also exactly the kind of gap a government facing fiscal pressure eventually closes, and a portfolio that has budgeted three quarters of flat power costs into its base case has no model for how fast that closure could arrive.

What should ASEAN portfolio managers do about a benchmark they can’t trust?

Treat the ESDM formula as a floor indicator, not a forecast. Model two scenarios for every Indonesian asset’s energy line item: continued freezes at current rates, and a snapback scenario where several quarters of suppressed formula output land in one or two adjustment cycles. Build hedging or reserve capacity for the second scenario now, while the first one is still in effect and cash is not under pressure. Portfolio managers who also hold Malaysian or Thai assets should not assume the same discretionary pattern applies there — Malaysia’s AFA mechanism has an explicit, and now exhausted, subsidy fund behind it, and Thailand’s relief structurally excludes commercial meters altogether. Each market’s override behaves differently, and none of them behaves like the predictable formula it was sold as.

Key takeaways

  • Indonesia’s ESDM has frozen non-subsidized electricity tariffs for three consecutive quarters (Q1–Q3 2026), overriding the formula in Ministerial Regulation No. 7 of 2024 each time, according to Archyde, SolarQuarter, and Petromindo.
  • Commercial meters that most office and retail buildings use — Business B-3/TM and Industrial I-3/TM — hold at Rp 1,114.74 per kWh despite Q3 inputs (US$96.12/barrel crude, a rupiah near Rp 16,959/US$) that would typically point toward an increase.
  • No public reporting identifies a funding mechanism absorbing the gap between the formula’s calculated rate and the frozen one, unlike Malaysia’s now-exhausted AFA subsidy fund.
  • Indonesia’s business electricity rates remain among the cheapest in ASEAN, per Katadata’s Databoks, which makes a future correction larger, not smaller, the longer the freeze continues.
  • Building owners and portfolio managers with Indonesian exposure should model a snapback scenario alongside the freeze-continues case rather than treating three quarters of stability as the new baseline.
