Saudi Arabia: Northern Region Cement Company (NRCC) has announced the signing of a contract for the construction of a US$8.7m, 20MW solar power plant in Turaif City. The plant will be supplied by Sinoma Overseas Development. The company says that the contract is in line with Saudi Vision 2030 and the company’s strategy to increase the use of renewable energy. Construction will take place over 10 months, with operations expected to begin in late 2026.

Sinoma Overseas Development will carry out the full scope of engineering design, procurement, supply and delivery during the contract duration time, in addition to civil construction, installation and commissioning.

Renewables reportedly generated more power than coal in the first half of 2025. Energy think tank Ember put out a report this week, which showed that solar and wind generation also grew faster than the rise in electricity demand in the first half of 2025. Global electricity demand rose by 2.6% year-on-year, adding 369TW. Solar increased by 306TW and wind by 97TW. Both coal and gas generation fell slightly, although a rise in other fossil fuel generation slowed the decline further.

Tellingly, fossil fuel generation fell in both China and India. Indeed, China added more solar and wind than the rest of the world combined, cutting its fossil fuel generation by 2% or by 58.7TWh. In India, renewables grew at the expense of fossil fuels, but demand growth was relatively low at 12TWh. In the US and the European Union (EU) fossil fuel generation actually increased. In the US, this was due to demand growth outpacing new renewable power. In the EU, weaker wind and hydroelectric output led to a greater reliance on coal and gas.

Meanwhile, a separate report by the International Energy Agency (IEA), also out this week, predicts that installed renewable power is likely to more than double by 2030 even as the sector navigates headwinds in supply chains, grid integration and financing. The IEA forecasts that global renewable power capacity will increase by 4600GW by 2030, roughly the equivalent of adding the total power generation capacity of China, the EU and combined. Solar photovoltaic (PV) will account for around 80% of the global increase in renewable power capacity over the next five years, followed by wind, hydroelectric, bioenergy and geothermal. Solar PV is expected to dominate renewables’ growth between now and 2030, remaining the lowest-cost option for new generation in most countries. Wind power, despite its near-term challenges, is still set for considerable expansion as supply bottlenecks ease and projects move forward, notably in China, Europe and India. However, the IEA’s outlook for global renewable capacity growth has been revised downward slightly compared to 2024, mainly due to policy changes in the US and in China.

This is all very well but what does it mean for the cement sector? At face value, possibly not much anytime soon. Both Ember and the IEA are talking about domestic electricity generation, not industrial. Ember reckons that half the world’s economies may have already peaked in fossil fuel power generation, but usage rates are still high. Prices of fossil fuels may even subsequently come down - to the benefit of industrial users such as cement plants. Yet, carbon taxes should, in theory, discourage increased usage - if they are working correctly.

Market distortions should not be discounted though. Some readers may recall what happened with carbon credits in the earlier stages of the EU emissions trading scheme. Free carbon allowances, calculated during the boom years of 2005 - 2007 when production was maxed out, were far too much to cover production during the resulting economic crisis. The sale of extra allowances provided many plants with a nice little earner and did little to encourage decarbonisation. Carbon capture is likely to require large amounts of electricity, but cheaper energy from renewables may help.

However, take a look at renewable energy stories in the Global Cement website news so far in 2025 and there are nearly 30 solar-related and seven wind-related ones. Cement companies are busily adding renewable capacity to reduce the cost of their electricity. This week, for example, Equator Energy commissioned a 10MW captive solar power plant at Mombasa Cement’s Vipingo plant in Kenya. Last week, Southern Province Cement in Saudi Arabia signed a 25-year solar energy power purchase agreement for its Bisha cement plant. Lest one forget, Saudi Arabia was the largest exporter of crude oil among Organization of the Petroleum Exporting Countries (OPEC) members in 2023 at 6,659,000 barrels/day. If a cement plant in Saudi Arabia is investing in renewables, then one might suspect a change in the global energy mix is occurring.

Electricity accounts for around 12% of the energy demand at a cement plant. Nearly two-thirds of that demand comes from either grinding raw materials or cement. Then, as mentioned above, carbon capture is expected to increase the demand for electricity. One estimate reckons it will increase electricity consumption by 50 - 120%. Renewables are expected to bring down the price of electricity but demand will also grow.

So… expect more renewable projects linked to cement plants.

Kenya: Equator Energy has commissioned a 10MW captive solar power plant at Mombasa Cement’s Vipingo facility in Kilifi County. The new installation will reduce the producer’s reliance on the national grid, reduce CO₂ emissions and deliver ‘substantial’ cost savings, according to Equator Energy’s post on LinkedIn. During construction, around 100 temporary jobs were created, while 15 permanent roles have been established to support ongoing operations. The project was implemented under a power purchase agreement (PPA) and is part of broader efforts to boost renewable energy adoption in Kenya’s industrial sector.

Saudi Arabia: Southern Province Cement has signed a 25-year solar energy power purchase agreement (PPA) with Tarshid Energy Solutions for its Bisha cement plant. The company said it will pay an average of US$1.07m/yr under the agreement. The solar power will reportedly be purchased at a cost lower than the company’s current electricity supply.

Construction of the solar system will begin on 1 October 2025, with operations expected to start in the third quarter of 2026. Southern Province Cement said that it will not require project funding, as it will not bear any capital or operational expenses. The company did not disclose details on the capacity of the new solar power plant.

Slovakia: Cementáre Cemmac has installed a US$4m solar power plant at its Horné Srnie plant in the Treniansky district of the country. The plant will produce over 4600MWh of electricity per year, to be consumed directly by the plant. This will reduce CO2 emissions by 4500t/yr. The facility has a 15-year technology guarantee and will operate until at least 2050.

Greece: Heracles Group, a member of Holcim, has commissioned a 6.5MW solar power station at its Milaki plant, equipped with more than 11,000 panels. The facility is now fully operational.

The installation is expected to generate about 10,000MW/yr of electricity, covering a significant share of the plant’s energy needs and cutting CO₂ emissions by 2350t/yr.

Türkiye: Limak Çimento will expand the solar power plant under construction in Kurtalan, Siirt, to meet the electricity demands of its cement plant, according to Energy Diary. The project, divided into five units, will increase its capacity from 9.91MW to 15.9MW with the addition of 6MW. The project site will increase from 109,000m² to 241,000m². The expansion will reportedly employ 10 people during construction and five in the operation phase.

India: Andhra Cements has commissioned a 6MW solar power plant at its cement plant in Palnadu district, Andhra Pradesh, according to India Infoline. The project forms part of the company’s initiative to reduce reliance on conventional energy sources and promote sustainable operations.

India: UltraTech Cement has commissioned a 7.5MW hybrid renewable energy project at its Sewagram cement plant in Gujarat. The on-site system combines bifacial solar modules with trackers, wind power and battery storage to provide uninterrupted energy without reliance on the grid. The project was developed with energy provider Gentari. The company aims to increase the share of renewable energy in its power mix to 65% by 2027 and 85% by 2030. As part of its RE100 commitment, UltraTech aims to meet 100% of its electricity needs through renewable sources by 2050.

India: Shree Cement has commissioned a 6MW solar power plant at its Roorkee unit in Uttarakhand, located next to its existing cement operations. This raises total solar capacity at the site to 7MW. The project cost US$1.8m, and brings the company’s total solar footprint to 294MW. It is expected to offset 6500t/yr of CO₂ emissions.
