US: Buzzi Unicem subsidiary Alamo Cement Company has successfully commissioned its new 17,800MWh solar power plant at its San Antonio cement plant in Texas. The producer says that the facility will eliminate 8000t/yr-worth of CO₂ emissions from the plant's operations. It spans an area of 18.2 hectares at the site of the 1.1Mt/yr cement plant. Texas-based energy provider CPS Energy built the installation.

Alamo Cement's director of engineering and construction management William Kovacs said "I am incredibly proud of the multi-discipline work that went into this first-of-its-kind project for Alamo Cement in San Antonio. It is an example of the type of collaboration necessary to continue to unlock and apply new energy sources for cement producers. It was a collective effort that brought together our corporate team, CPS Energy and regional engineering firms and contractors."

South/Central America: Holcim Latinoamérica says that it expects to use 18% renewable power across its operations in February 2023, compared to 8% throughout 2022. The regional unit of Holcim says that it will increase its share of renewable power to 25% by the end of 2023. It is committed to a target of 60% renewables by 2030. Holcim Latinoamérica's operations span Argentina, Colombia, Costa Rica, Ecuador, El Salvador, Nicaragua and Mexico.

Earlier in February 2023, Holcim Nicaragua commenced construction of a 3.38MW solar power plant in Nagarote, León Department. The producer said that the solar power plant's contribution to the national grid will cover 40% of its consumption in its cement operations there.

Holcim's Latin America regional head Oliver Osswald said “Our world is in constant change from population growth, urbanisation and the climate challenge. That is why, at Holcim, we are determined to put our best foot forward to accelerate low carbon circular construction."

Egypt: Suez Cement has partnered with Intro Power and Utilities for the construction of a 20MW solar power plant at its Suez cement plant. From its commissioning in early-mid-2023, the installation will provide the plant with 45GWh of energy annually, 20% of its annual consumption. Suez Cement says that this will eliminate 22,000t/yr-worth of CO₂ emissions. Construction is expected to cost US$350m and commence in 2023.

Suez cement aims to achieve specific CO₂ emissions of 400kg/t of cementitious product by 2030, down by 47% from 1990 levels.

Managing director Mohamed Hegazy said “Through transitioning to renewable solar energy, we are looking at long-term economic benefits, laying the foundation for a low-carbon business and energy security, without jeopardising the health of our environment. We are proud about this new milestone and to be one of the few cement players in Egypt taking this step towards using a more affordable and cleaner energy."

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.

Mexico: A group of approximately 400 former workers of Cooperativa la Cruz Azul, who maintain possession of the Tula cement plant in Hidalgo, staged a demonstration on 22 August 2022 in front of the offices of the Federal Electricity Commission (CFE) demanding that power to the plant be reinstated.

Through a press release, the CFE said that it had met with some of the protesters. After negotiations, it concluded that the reconnection of the plant "will be made as soon as notification is received from the court or competent authority."

Local reports have suggested that the cut was ordered on 17 August 2022 by Víctor Manuel Velázquez Rangel, who heads the Board of Directors of the Cooperativa la Cruz Azul, the legal owner of the plant. The justification was that the plant has become dangerous to operate after two years of occupation by the protestors.

China: Taiwan Cement Corporation and Asia Cement Corporation, both based in Taiwan, have said that extended power rationing in China’s Sichuan Province has had only limited impacts of their cement plants in the region. They reported that they had complied with the authorities’ requirements by scheduling maintenance work for their factories and that they would continue to closely monitor the development of the power situation in the Province.

Power rationing has been introduced in Sichuan Province due to reduced hydroelectric power capacity, which has been affected by the most severe heatwave and drought in the region for 60 years.
