Cembureau called for urgent action on electricity prices from European governments this week to protect cement plants. Its maths was crushingly simple. One tonne of cement takes around 110kWh of electricity to produce. Electricity prices started to top Euro700mWh in some European Union (EU) countries at the end of August 2022. The association says that this represents added costs of Euro70/t of cement and a tripling of the total cost of production. This kind of sudden extra cost to cement production could lead to the widespread closure of cement plants and lead to chaos in the construction supply chain.

Previously, Cembureau reported in 2020 that electricity accounts for about 12% of a cement plant’s energy mix. In a dry production process plant 43% of this is used for cement grinding, 25% goes into raw material preparation, another 25% on clinker production and the final portion is typically used for raw material extraction, fuel grinding and for packing and loading. However, the cost of the electricity can make a big difference to the overall energy bill for a cement plant. When a report by the European Commission’s (EC) Joint Research Centre (JRC) modelled a reference northern European cement plant with a production capacity of 1.0Mt/yr back in 2016, it concluded that the EU cement industry was spending around half of its energy costs on electricity compared to smaller ratios at plants in China, Egypt, Algeria and... Ukraine. That last country in the list is poignant given its unwitting participation in the current energy crisis. One other thing to note is that cement producers, as large scale users, may well be paying less than the wholesale prices Cembureau appears to be quoting.

The timing of Cembureau’s proclamation is pertinent because the EU and individual states have mostly been waiting until the autumn before revealing their energy support plans. However, the dilemma for Cembureau, and other industry lobbying groups, is how to protect their sectors whilst domestic consumers are threatened. The aftermath of the coronavirus lockdowns has shown what can happen when production of key commodities stops: supply chain disruption, shortages and price rises. One ironic shortage in the UK during the lockdown periods was that of CO₂, as high gas prices forced the main producer to shut down, leading to unexpected knock-on problems along the supply chain in areas such as food production. The same situation is reportedly at risk of happening again now too.

Cembureau’s wider solution is to link domestic and industrial consumers of electricity. So, some of its suggestions to policymakers are to use all available means of power generation, implement emergency measures such as price caps immediately, change the rules of the electricity market more generally to prevent future price shocks and to promote large scale renewable power source development. These are all things that could help both individual and industrial users of electricity.

Compare and contrast, then, with the MPA’s (Mineral Products Association) approach to the same problem in the UK. Its strategy instead has been to ask the UK government for tax cuts and freezes and to hurry along the forthcoming policy on support for Energy Intensive Industries. That’s not to say that Cembureau’s suggestions don’t also include some sector specific requests. It has asked that the EU temporary state aid framework adopted in late March 2022 should allow all energy intensive industries to have access to state aid covering 70 - 80% of eligible costs. It has also encouraged the wider use of alternative fuels, although it doesn’t link the reason why beyond reducing imports of fossil fuels. Lastly, it bangs the drum for its recent preoccupation, the EU Carbon Border Adjustment Mechanism, this time adding electro-intensity as a main criterion for eligibility for compensation under EU emission trading scheme (ETS) indirect state aid guidelines.

Government support packages for the energy crisis are starting to be announced in European countries but the question for everyone is whether they and other actions will be enough. One problem for the cement industry will be simply staying on the radar of policy makers facing a crisis looming over their citizens. Yet if there is not enough energy to go around then rationing of some kind will be inevitable and heavy industrial users will be the first obvious targets to be told to cut back. Some months later building material supply shortages will hit. One national cement sector to watch in the coming months may be the Spanish one as it has long warned of the risks of high electricity prices.

Belgium: Cembureau, the European Cement Association, has called for urgent action to be taken to support cement production due to large increases in the cost of electricity. It said that, if no measures were taken at both the European and national level, the current energy prices would lead to widespread plant closures across the European Union (EU). This in turn could create a crisis in the construction supply chain. It explained that one tonne of cement normally takes around 110kWh of electricity to produce. Therefore, with electricity prices now between Euro700 - 1000mWh, as observed in several EU member states, electricity costs amount to Euro70 – 110/t of cement, tripling the total cost of production.

The association has called for: all available sources of electricity generation to be used to boost power supplies; the immediate introduction of emergency measures, such as price caps; that the EU temporary state aid framework adopted in late March 2022 should allow all energy-intensive industries to have access to state aid covering 70 - 80% of eligible costs; and that co-processing in cement kilns should be actively encouraged and promoted at EU, state and local levels.

It added that further measures should also be considered, including: the electricity market design rules, including the marginal price setting mechanism, should be changed to prevent further electricity price hikes in the future; the cement sector should be made eligible for financial compensation under the EU emission trading scheme indirect state aid guidelines and that indirect emissions should be included in the EU Carbon Border Adjustment Mechanism (CBAM); the large-scale deployment of renewable energy should be supported across the EU; and that the pace of the EU climate agenda ('Fit for 55') should be maintained, and the CBAM should be implemented in a timely manner.

China: Sichuan Yadong Cement’s plant in Sichuan has restarted production following a suspension of electricity to industrial users due to a heat wave. The local authorities stopped supplying industrial plants in late August 2022. The subsidiary of Taiwan-based Asia Cement Corporation also reduced staff levels at the plant to cope with the extreme weather event.

Mexico: Cooperativa la Cruz Azul’s Tula cement plant in Hidalgo has agreed with the Federal Electricity Commission (CFE) that electricity supplies will restored no later than 7 September 2022. Federico Sarabia, cooperative chair and leader of a dissident group claiming to own the plant, said that the plant has made losses of over US$15m due to the outage, according to the El Sol de la Laguna newspaper. The electricity supply to the site was reportedly cut in mid-August 2022 at the request of Víctor Manuel Velázquez, the head of the board of directors of the group.

State police intervened during a confrontation between rival groups for control of the Tula cement plant in late July 2022. The plant is the sole remaining Cruz Azul unit still reportedly controlled by former company director Guillermo ‘Billy’ Álvarez and his associates. The rest of the company is under the command of Cruz Azul’s directors José Antonio Marín and Víctor Manuel Velázquez. This group started asserting legal control of the cooperative’s cement plants in Puebla and Aguascalientes from mid-2020.

India: 30% of plants in India’s 78GW captive power plant network have temporarily closed due to high coal prices. 40GW-worth of capacity (55%) is coal-fired, with an annual consumption of 200Mt/yr. The Business Standard newspaper has reported that total Indian coal imports fell by 10% to 23.8Mt in July 2021 from 26.3Mt in June 2021. Deliveries of coal to non-power sector consumers fell by 33% year-on-year at the beginning of August 2021. The Indian Cement Manufacturers Association (CMA) and nine other national industry associations have contacted the government to urge the formation of policies for the equitable distribution of available coal.

India Cements has imported two shipments of Russian coal for use in cement production. The company’s power and fuel costs rose by 54% year-on-year in the first quarter of its 2023 financial year, which began on 1 April 2022. Its vice-chair and managing director Narayanaswami Srinivasan said “Most of our plants have coal-based captive power generation. The cost of captive generation is now more than the grid cost. Hence, we shut down all captive power units and resorted to grid power.”

Germany: Loesche has published its Sustainability Report of its performance in 2021. The supplier’s Scope 1 and 2 CO₂ emissions declined by 6.1% year-on-year to 229t from 244t in 2020 and by 19% over the two years from 2019, when they totalled 282t. It reduced the share of Scope 2 emissions in the figure to 40% from 41% in 2020 and 45% in 2019.

Loesche offers emissions-reducing products to the global cement industry under the label Greenkey Solutions. These include its A/Fuel and H/combust ranges for alternative fuels and green hydrogen upgrades, its C/Clay range for clay calcining and grinding, its Digital/Ready 4.0! range for predictive process optimisation and smart asset management, its E/Slag range for ground granulated blast furnace slag upgrades and its S/Crete range for waste concrete recycling, as well as audits for retrofits. Together, Loesche says that its products can reduce the global cement sector’s carbon footprint by 90%. Within this, Loesche believes that calcined clay technology alone can reduce cement’s CO₂ emissions by 40% and its energy demand by 21%.

Loesche said that its launch during the year of its H₂Optimum grinding bed spraying system can reduce grinding mills’ water consumption by 50%.

India: Dalmia Bharat sold 6.2Mt of cement in the first quarter of its 2023 financial year, up by 27% year-on-year from 4.9Mt in the first quarter of its 2022 financial year. Its sales revenues also rose by 27%, to US$417m from US$327m. The growth failed to translate into increased profitability, however, with the company recording a profit after tax of US$25.9m, down by 27% from US$35.3m.

Dalmia Cement (Bharat) Managing Director and CEO Mahendra Singhi said “I am pleased with our performance this quarter. Our sustained efforts on operational efficiencies and cost rationalisation have enabled us to mitigate the adverse impact of inflation and deliver our lowest total cost of production. Our capacity expansion projects are on track, and we have added 2Mt/yr of clinker capacity and 1.1Mt/yr of cement capacity, which takes our cement capacity to 37Mt/yr. We remain firm on our Carbon Negative Roadmap, and during the quarter have installed 41.4MW of renewable energy infrastructure.”

Kenya: East Africa Portland Cement began work to replace a 16.5m-length of kiln shell at its Athi River cement plant at the end of July 2022. The producer says that the project will increase the kiln line’s capacity by 1400t/day.

Managing director Oliver Kirubai said "Due to the high costs of energy and an old clinker line, the board has prioritised efficiency and reliability of our integrated plant operations to drive cost optimisation.”

Nigeria: Dangote Cement increased its sales by 17% year-on-year to US$1.9bn in the first half of 2022 from US$1.63bn in the first half of 2021. The group increased its cement sales volumes by 26% to 15.Mt, including a 33% increase in Nigeria to 9.9Mt there. Its production costs rose by 17% to US$760m from US$651m. This resulted in a 10% profit drop to US$406m from US$452m.

Chief executive officer Michel Puchercos noted a ‘very volatile’ global environment and increased energy costs. He said “Our business model remains robust, thanks to the prudent and flexible approach we have taken across our operations. Our continuous focus on efficiency, meeting market demand and maintaining our costs leadership drives our ability to consistently deliver superior profitability and value to all shareholders.”

Germany: HeidelbergCement’s sales revenue rose by 11% year-on-year to Euro9.95bn in the first half of 2022 from Euro8.94bn in the same period in 2021. Its cement and clinker sales volumes dropped by 4.8% to 58.8Mt from 61.8Mt, while its profit for the period attributable to shareholders dropped by 28% to Euro542m from Euro755m. During the reporting period, the producer reduced its net debt by 8.9% to Euro6.79bn from Euro7.45bn.

Chair Dominik von Achten said "The first half of 2022 was characterised by the strong increase in energy and raw material prices. In this persistently difficult market environment we were again able to significantly increase our revenue.” He continued, “In view of the unprecedented increase in energy prices in recent weeks, the second half of the year remains challenging. For the full year, we continue to expect a significant increase in revenue, while for the result from current operations we now anticipate a slight decline on a comparable basis compared to the strong previous year.”
