Omer Ashraf isn’t losing any sleep over the impact of the Iran conflict on his fleet of energy-hungry cement plants. The Chief Financial Officer of Pakistan’s Fauji Cement Co. installed its first solar array in 2019 at Jhang Bhatar, about 50 kilometers (31 miles) west of the capital Islamabad. There are now 69 megawatts of panels across the company’s five main sites, at least twice what Tesla Inc. appears to have on the rooftops of its gigafactories in Nevada and Texas. They contribute about 23% of the company’s electricity, with a further 35% coming from recovering waste heat from its coal-fired clinker kilns.
