Take a moment to spy on the Citeureup cement plant in Indonesia. It's gargantuan! The Indocement site is one of the largest cement factories on the world. It has nine production lines with a cement production capacity of 11.9Mt/yr.

The news this week that Indocement intends to stop production at three cement production lines at its Citeureup plant strikes an uncertain tone. The decision underpins the impression of a readjusting Indonesian cement market despite the HeidelbergCement subsidiary saying that the capacity will be replaced by a new 4.4Mt/yr line at the site at the end of 2015. Temporarily reducing production capacity by 35% may not seem much on a industrial site that can produce more cement than many countries! However, a single factory this massive is likely to be particularly vulnerable to market changes.

Zooming out to the national picture, Indocement reported that its revenue dropped by 6.6% year-on-year for the first half of 2015. Domestic sales volumes of cement fell by 8.1% as domestic cement consumption in the country generally fell by 4.2%. The cement producer blamed the falls on economic stagnation and delayed government spending on infrastructure projects.

In its outlook Indocement lamented the loss of subsidies on electricity and fuels in Indonesia. Back in 2014 the government raised electric prices via a tariff under the previous administration before lowering them slightly. Then the new government raised fuel prices in November 2014 by removing subsidies with the intention of siphoning the savings to infrastructure spending. At the time a Semen Indonesia representative told the Jarkata Post that he expected cement sales to rise by 6% in 2015. This estimate had already followed a downward adjustment of predicted sales in 2014 due to familiar sounding delays in infrastructure projects (due to an election year) and a slowing economy.

In addition to this the government also imposed price cuts on cement on state-run producers in January 2015. Semen Indonesia then saw its domestic sales volumes fall by 5.3% in January – May 2015 to 9.91Mt. Subsequently Semen Indonesia saw its net profit drop by 21% year-on-year to US$163m for the first half of 2015. Around a month before its mid-year results it reported to local media that it was concentrating on exports in 2015. Reported exports have risen by over 700% to 0.18Mt in January – May 2015. Other producers such as LafargeHolcim have also reported 'challenging' market conditions. Nationally, cement demand dropped by 3.8% year-on-year to 22.9Mt for the first five months of 2015 according to Indonesian Cement Association data. This was the biggest fall since 2009.

All in all it sounds like the good times may be gone for the Indonesian cement industry, at least for now. The local economy as a whole is in a recession following two consecutive quarters of declining growth in gross domestic product (GDP). Yet cement producers are still forlornly hoping for infrastructure spending to kick in. Throw in worries about the effects of a US interest rate rise on Indonesian borrowing and the situation is looking dicey. Indocement's Citeureup complex may seem even more outsized in a year's time.

UPDATE:  A reader has pointed out that we linked the aerial photo at the start of this article to the smaller of the two cement plants in the area. This has now been changed. Note the trucks queuing to enter the plant.
