Colombia: Cementos Argos is switching its trucks in Medellín to electric-powered vehicles. The new trucks will be powered by 600v batteries and be capable of carrying 4t of cement, according to the La Republic newspaper. The cement producer is planning to expand the electric-powered trucks to other cities subsequently.

Nepal: Cement producers including Narayani Cement, Kalash Cement and Bishwokarma Cement have reported damage from a heavy thunderstorm that has hit the south of the country. At least 30 people were killed in the bad weather and other 600 people were injured, according to the Kathmandu Post newspaper.

Umesh Chandra Thakur, manager at Narayani Cement, said the storm had knocked down walls, a roof and power lines at the plant, leading to a halt in production. Kalash Cement also reported that the roof of its plant had been blown off. The storm has also caused widespread disruption to the electricity distribution system in Bara and Parsa districts.

Vietnam: A 8.36% rise in electricity prices in late March 2019 is set to cause an increase in the price of cement. The Vietnam Cement Industry Corporation (VICEM) said that cement producers had also been hit by an increase in coal prices, according to the Vietnam News Agency. The rise in the price of coal follows a lack of supply from the Vietnam National Coal and Minerals Industry Holding Group (VINACOMIN) leading to producers to import coal. Cong Thanh Cement has not raise its retail prices but has charged distributors more. Nguyen Quang Cung, chairman of the Vietnam Cement Association, said that producers were not surprised by increase in electricity prices and had been preparing for it.

Philippines: Holcim Philippines has ordered power monitoring equipment from CMR Philippines for its 2.3Mt/yr Lugait cement plant in Misamis Oriental. It includes the development, delivery, installation, testing and networking of the electrical installation at the unit. Current and voltage transformers are to be supplied as part of a package of engineering support that also sees CMR completing the integration and connection of plant wide power monitoring to Siemens PCS 7 process control technology.

“Winning the Holcim contract reflects the expertise we can bring to successfully delivering complex and technologically advanced industrial projects,” said Rojel Rivera, general manager at CMR Philippines.

CMR Philippines is part of the CMR Group, which designs, manufactures and commissions automation, control system and turnkey project solutions for global industrial and renewable energy sectors, alongside specialist instrumentation for high power diesel engines.

Cameroon: The electricity supply in parts of central and southern Cameroon has been disrupted whilst a substation at Nomayos near Yaoundé is connected to the main network. The disruption is necessary ahead of the commissioning of Cimencam’s Nomayos cement grinding plant, which is scheduled for the first quarter of 2019, according to Business in Cameroon. The new plant will have a production capacity of 0.5Mt/yr. It has an investment of around US$40m.

Nepal: Udayapur Cement’s production is being reduced due to power cuts. The plant has a production capacity of 800t/day of clinker but at times it has been reduced to only just 100t/day, according to the Republica newspaper. The cement producer says that the cuts have cost it over US$0.4m.

The electricity outages have also damaged machinery such as gears in cement-packaging equipment and raised general costs through repeated start-ups. The unit suffered 62 power cuts from 15 January to 2 February 2019 lasting a total of 23 hours. As many as six stoppages in a single day have been reported.

The Nepal Electricity Authority supplies electricity to the plant. It has blamed the ‘incompetence’ of officials at a substation.

Sweden: HeidelbergCement’s subsidiary Cementa has completed a feasibility study into electrifying its cement plant at Slite in Gotland as part of its Cemzero project. A report from the first phase of the project has been submitted to the Swedish Energy Agency.

The study found that using electricity to supply heat during the clinker production process is possible using plasma technology, although this needs to be tested on a larger scale. Using an electrified process was found to be competitive compared to other options for achieving high reductions in carbon emission. The production cost of cement would be doubled approximately but the research suggested that this might only mean a small percentage increase to the end cost of a building or an infrastructure project. Finally, the study reported that any future electrification of the Slite plant would work well with a planned expansion to wind turbine generation at the site. It would improve the energy balance and reduce the maximum power surplus that might occur.

Cementa and energy company Vatenfall will now look at how to build a pilot plant.

Chile: Cementos Polpaico has blamed a loss of US$3.2m in 2018 on changing an electricity supply contract. Changing the contract to move to a new supplier, Colbún, led to a negative financial impact of around US$12.5m. Its sales rose by 23% year-on-year to US$249m in 2018 from US$202m in 2017. Its sales volumes of cement grew by 10% to 1.35Mt from 1.23Mt. Despite the overall loss its earnings before interest taxation, depreciation and amortisation (EBITDA) increased by 51% to US$18.7m from US$12.4m.

Kyrgyzstan: Commissioning of the Kemin cement plant in Chuy region has been delayed due to electricity supply issues. Members of parliament have been discussing the delayed opening of the plant, according to the Central Asia News agency. The Chinese-backed plant project held its ground-breaking ceremony in mid-2014. It had an investment of US$120m. The unit has reportedly been built but it cannot be commissioned due to technical issues relating to its electricity supply, despite being situation close to the Datka Kemin power station. A working group was created in December 2018 to work with investors to solve the problems.

UK: Cemex says that it will use 100% renewable electricity at supplied sites in a partnership with energy, services and regeneration group Engie. Engie has been providing electricity to over 150 Cemex UK sites for over 10 years, also supplying gas to 33 of these sites. The current contract is to be extended for a further 12 months. All of the electricity supplied to the sites will be from 100% renewable energy sources including wind energy.

“Cement manufacture is inherently energy-intensive and we work hard to minimise energy consumption within the process constraints. The switch to electricity from renewable sources is playing a key role in our carbon reduction strategy,” said Martin Hills, Head of Energy and Carbon at Cemex in the UK.

Cemex is also using Engie’s demand side services, such as load management to avoid peak tariffs and rapid frequency response, which generates extra revenue for Cemex UK. Engie manages all contractual requirements with National Grid on Cemex UK’s behalf.
