Kyrgyzstan: China-based Yunsheng Mining (Yunnan) and China Yunsheng Group have signed an agreement with the Kyrgyz government to build a cement plant in Tyup, Issyk-Kul region. Business World Magazine has reported that the partners will also establish a hydroelectric power plant next to the plant. Yunsheng Mining (Yunnan) said that the project will help to promote a new model of economic cooperation between Kyrgyzstan and China, based on the integration of commodities and energy.

Austria: W&P Zement says that it has commissioned an expanded 18GWh Wietersdorf hydroelectric power plant chain on the River Görtschitz in Carinthia. The chain consists of two new power plants and an existing one which the company optimised during a Euro12m project begun in October 2019. Together, the plants will supply 25% of the producer’s Wietersdorf cement plant’s electricity needs.

Technical director Florian Salzer said “With six modern Francis turbines, 18GWh of green electricity are generated in three power plants along the Görtschitz.” He added “That roughly corresponds to the supply for 3600 four-person households.”

Brazil: Votorantim Energia and Canada-based CPP Investments have announced the consolidation of their Brazilian energy assets in a new jointly owned renewable energy platform called VTRM. The new company's assets will reach 3.3GW in capacity by October 2022, consisting of 2.3GW in hydroelectric power and 1.0GW in wind power. Its planned projects, including hydroelectric, solar and hybrid power plants, will increase its capacity by 58% to 5.2GW.Its existing assets sold 2.6GW of electricity in 2020. The partners said that the new company will also be well-positioned for future growth, including the acquisition of operational assets and those in planning or under construction. CPP Investment will inject and additional US$269m into the venture following the conclusion of the deal.

As part of the restructuring, Votorantim Energia will cease to manage Votorantim's cement subsidiary Votorantim Cimentos' dedicated energy assets. The cement producer will then incorporate these into its own operations. This will enable Votorantim Energia to focus on energy generation for sale.

Group president João Schmidt said that the consolidation reflects the major role that energy business will play in the company's future. He said "Globally, there is a growing urgency around renewable energy and the energy transition. Alongside a partner like CPP Investments, which has shared our long-term views on energy since 2017, we are ready to accelerate our role in the sector." He added "Through the assets consolidation into a single platform, Votorantim and CPP Investments will share in a new cycle of growth and value generation together."

Pakistan: The government has announced plans to complete the construction of the Daimer-Basha Dam on the River Indus in Khyber Pakthunkhwa and Gilgit Baltistan. Daimer-Basha Consultants Group holds a consultancy contract worth US$169m for the project, and the government has awarded the energy supply contract for the dam’s 21MW hydroelectric power plant to a joint venture of the military Frontier Works Organisation and China-based Power China. Besides power generation, the aims of the project are to increase the area of land useable for agriculture and to stop floods and droughts. Flare Business News has reported that the dam, construction of which first began in 1998, will generate a demand for ‘huge quantities’ of cement and steel and create 16,500 jobs.

India: Cement Corporation of India has signed a memorandum of understanding with power supplier NHPC Limited in order to ‘address the cement requirement’ for the Dibang Multipurpose Project in Lower Dibang Valley district, Arunachal Pradesh. The project is aimed at the construction of a 2880MW hydroelectric power plant and gravity dam for flood control in the Dibang Valley.

Ethiopia: Electricity rationing has been restricting the production of cement companies since it started in April 2019. Under a program implemented by Ethiopian Electric and the Ministry of Water and Energy, cement producers are only allowed to operate for 15 days per month, according to the Reporter newspaper. They say this has increased their production costs because cement production is a continuous process that requires start up and stoppage time. The Ministry of Trade has asked that cement producers do raise the price of cement despite the increase in production cost. Input and transport costs have also risen.

“There is a huge waste of resources when we start up and stop running our plant. Continuous production has cost benefits. We spend 24 hours warming up the plant. There is wastage of coal and electric power,” said Mesfine Abi, the chief executive officer (CEO) of Habesha Cement. He added that the company is facing growing maintenance costs as its machines fail to cope with repeated power cuts.

The national electricity power restrictions have been caused by water shortages at hydroelectric dams. Rainwater has started flowing back in the dam reservoirs but power rationing is not expected to be rescinded until early July 2019.

Germany/Portugal: Talleres Alquezar has been using two BHS mixers in a modular plant to produce a total volume of 400,000m³ of hydro dam concrete in Portugal since 2017. Two DKX 4.5 type twin-shaft batch mixers, each with a capacity of 4.5m³, have been integrated into the plant. Germany’s BHS says that using twin-shaft batch mixers has shown that can be utilised successfully to produce this kind of specialised concrete.

Three hydro dams are being built on the Tâmega River that are expected to generate 1760GWh for the Iberian market once they have been commissioned as part of Spanish energy group Iberdrola’s large-scale hydroelectric project in Portugal. 242,000m³ of concrete is needed in Daivões for the dam wall alone, which is planned to be 78m high and 265m long. Spain’s Talleres Alquezar is the project partner for this hydro dam. Once built, the construction in Daivões is expected to dam up to 56,200,000m³ of water.

Uganda: Hima Cement, a subsidiary of LafargeHolcim, is a building materials partner for the on-going 600MW Karuma Hydropower project on the River Nile. The plant is being built by China’s SinoHydro Corporation at an estimated cost of around US$1.7bn. The project was started in 2013 and it is scheduled to be completed in December 2019.

Hima Cement has been one of two cement suppliers assisting it. It has provided a fine cement that maintains its early strength while requiring a lower water content. Over 114,000t of Powermax CEM II A-P 42.5N have been supplied to the project, chosen for its low heat requirements for hydration and its pozzolanic content which results in long-term durability. Delivery of this product has required a dedicated fleet of 60 bulk cement trucks when cement demand for the project was at its peak.

Chile: Cementos Bicentenario (BSA) has signed a deal with energy company Engie to supply its Quilicura grinding plant near Santiago with renewable energy. All of the energy supplied to the plant will come from renewable sources including solar and hydroelectric. The contract, equivalent to 35GWh, will see the plant achieve the I-REC certification.

India: Sagar Cements has acquired two mini hydroelectric power plants from Sagar Power in Andhra Pradesh.
