Jakarta. The government has capped the price of domestic coal for power stations at $70 a metric ton for two years, in new rules issued this week, an official said on Friday (09/03).
Indonesia is the world's biggest exporter of the dirty fuel and the rules could hit miners currently enjoying coal prices at their highest level in five years.
With elections looming in 2019, the government plans to keep electricity tariffs unchanged this year and next, and the cap on thermal coal for power is intended to shield state-owned utility Perusahaan Listrik Negara (PLN) from price fluctuations.
"The [maximum] price of coal ... for power stations is $70, fixed," Energy Ministry spokesman Agung Pribadi said on Friday at a news conference on the step and other new rules.
That price is based on coal with a calorific value of 6,322 kilocalories, the same specification as in the Indonesian Coal Benchmark Price (HBA).
The rule will be applied retroactively to Jan. 1, 2018, and will be reviewed in December, 2019.
Where the HBA drops below $70 per ton, the domestic thermal coal price for power stations will revert to HBA, Agung said.
The monthly Indonesian Coal Benchmark Price (HBA) was set last week at $101.86 per ton for the month of March, its highest since May 2012.
The new rule allows coal miners supplying PLN to apply for an increase to their approved production quota for the year of up to 10 percent.
"Energy and Mineral Resources Minister Ignasius Jonan emphasizes this setting of coal prices for power stations is so that electricity rates can be maintained, to protect people's purchasing power and competitive industries," Agung said.
The rules are expected to generate savings of Rp 18 trillion ($1.31 billion) for PLN if the HBA stays above $100 this year, PLN strategic procurement director Supangkat Iwan Santoso told reporters.
Under the new rules, PLN, which uses coal with a calorific value of between 4,200 and 4,500 kcal, will pay around $37 per ton for coal while the HBA remains above $70, Iwan said.
At the current HBA price, PLN pays around $55 per ton, he added. PLN expects its coal demand to climb 18 percent this year to 90 million tons.
The government has been working on plans to regulate domestic coal prices since late 2017, under pressure from PLN, and the discussions have knocked back some coal miners' share prices.
Over the past three months, the Indonesian mining share index has gained more than 22 percent, outperforming all other asset classes, and is up around 33 percent over the past year. But, in the past five days, the sector has fallen over 6 percent - more than any other.
"We are still studying the impact [of the new rules]. We want market prices," said Indonesia Coal Mining Association executive director Hendra Sinadia.
According to Suherman, corporate secretary for state-owned coal miner Bukit Asam, "the impact of the new price is not really significant on our target revenue and bottom line."
A spokeswoman for Adaro Energy, Indonesia's second-biggest coal miner by output, declined to comment.
Adaro shares were down just over 3 percent at 0715 GMT.
The government has said national coal output could reach 485 million tons in 2018, up from a realized output of 461 million tons in 2017.
About a quarter of this - 118 million tons - is to be for domestic coal consumption, with the rest exported.
