Cemex tells a Zagreb fair it uses 145 GWh a year and that 6.4 MW of solar covers 6% - the 18 MW finish was spoken at the fair, and the company page prints a different next step
HRT and Hina reported on 28 October 2026 from the Green Energy Fair in Zagreb. Cemex board member Marijan Vuko said the firm uses 145 GWh a year, that 6.4 MW of solar on 28 sites covers 6% of its electricity, and that nine more sites are in construction. He named a finished plan of 18 MW, covering 17% to 18% of the firm's own use. Cemex's page of 23 September 2025 prints 6.377 MW, 8.4 GWh a year as 6% of annual energy needs, and a plan for another 17 GWh. No battery is named on either page.
A cement plant is a large workplace power bill. On 28 October 2026, at the Green Energy Fair in Zagreb, a Cemex board member put figures on that bill. The company's own page, from September 2025, prints a different next step. Neither page names a battery.
HRT, citing Hina, reported the fair the same afternoon. Marijan Vuko, a member of the Cemex board, said the firm is among the larger electricity users in Croatia, at 145 gigawatt-hours a year. He called electricity the firm's largest cost. Solar is on 28 sites, 6.4 megawatts in total, covering 6% of electricity needs. Nine more sites are in construction. When every planned site is finished, he said, solar will stand at 18 megawatts and cover 17% to 18% of the firm's own consumption.
The company page is dated 23 September 2025. It covers solar at three places: the Sv. Juraj plant in Kaštel Sućurac, the Sv. Kajo plant in Solin, and the Podsused terminal in Zagreb. The build is priced at over €5 million, with €2.9 million from the EU Modernisation Fund. It counts 28 buildings, 6.377 megawatts, and 8.4 gigawatt-hours a year. That 8.4 gigawatt-hours is printed as 6% of Cemex Hrvatska's annual energy needs. The page also prints a cut of 1,337.57 tonnes of CO2 a year. Marijan Zekić, who leads projects and quality at the firm, said further projects are in progress to secure another 17 gigawatt-hours of renewable production for the business. The page states a company goal of drawing 65% of electricity consumption from low-carbon sources. That 65% is a goal. The 6% is the share this solar project is printed as covering.
The words do not match. The fair report says electricity. The company page says energy needs. 8.4 divided by 145 is about 5.8%, by our arithmetic. The company prints 6% against 8.4 gigawatt-hours and does not print 145. The fair prints 145, 6% and 6.4 megawatts, and does not print 8.4 gigawatt-hours. 6.4 megawatts is a rounding of 6.377. The pages agree on 28 and on a share of about 6%. They do not share one sentence.
The next step splits three ways. The fair: nine sites in construction, then 18 megawatts and 17% to 18%. The September page: another 17 gigawatt-hours, with no megawatt total and no count of new sites. On 28 January 2026 Portal.hr quoted the firm on a mine plant still at the conceptual-design stage, 9.9 megawatts, which would take own renewable production to 16.5 gigawatt-hours a year. 16.5 minus 8.4 is 8.1, by our arithmetic. Portal.hr does not print 8.1. A reader who stacks the fair's 18 megawatts, the page's extra 17 gigawatt-hours and the portal's 9.9 megawatts is stacking three different sentences.
A yield check, labelled as ours. 8.4 gigawatt-hours from 6.377 megawatts is about 1.32 gigawatt-hours per megawatt. Another 17 gigawatt-hours at that rate is about 12.9 megawatts. 6.377 plus 12.9 is about 19.3 megawatts. The fair said 18. The pages do not print this multiplication, and they do not print one total.
No battery. The fair report does not name one on the Cemex roofs. The September page does not name one. The January mine story does not name one. A separate Croatian grant for solar and batteries at farms and food plants is already on this desk, in the Modernisation Fund note. Cement production is not that call.
Same fair, a different sentence. Marija Šćulac, vice-president of the Croatian Chamber of Economy, said the price of electricity for firms rose 120% over six years. HRT prints the remark. It does not print the price series behind it.
Analogy: 6% is the slice the company page ties to roofs that are already described. 18 megawatts is a sentence spoken at a fair. The two do not share a signed total. The battery line on both pages is blank.
Good: A public fair date, a named speaker, and a company page with euros, megawatts, gigawatt-hours and a percentage a buyer can open.
Bad: The fair and the company page use different next numbers. Electricity and energy needs are different words. No price for the nine new sites. No battery size. The 120% remark has no table attached.
Ugly: Treating 18 megawatts as built. Treating 6% as if it were already 18 megawatts. Reading 145 gigawatt-hours as a figure the company page prints. Adding a battery the reports do not name. Using the 65% goal as this year's solar share.
Soft next step: put 6.377 MW, 8.4 GWh and the fair's 18 MW on one sheet, and leave the battery line blank until a page prints a battery.
Source: HRT / Hina, 28 Oct 2026, 14:57 - Green Energy Fair. Primary for the fair report: Marijan Vuko of Cemex on 145 GWh a year of electricity use, electricity as the firm's largest cost, 6.4 MW of solar on 28 sites covering 6% of electricity needs, nine further sites in construction, and a finished plan of 18 MW covering 17% to 18% of own consumption. Also primary for Marija Šćulac of the Croatian Chamber of Economy on a 120% rise in the business electricity price over six years. The report does not print a price table, a euro cost for the new sites, a battery, or 8.4 GWh. Cemex Hrvatska, 23 Sep 2025 - solar project results. Primary for solar at Sv. Juraj in Kaštel Sućurac, Sv. Kajo in Solin and the Podsused terminal in Zagreb, a build of over €5 million with €2.9 million from the EU Modernisation Fund, 28 buildings at 6.377 MW producing 8.4 GWh a year, that output as 6% of annual energy needs, a cut of 1,337.57 tonnes of CO2 a year, Marijan Zekić on further projects for another 17 GWh, and the 65% low-carbon electricity goal. The page does not print 145 GWh, 18 MW, nine new sites, or a battery. Portal.hr, 28 Jan 2026 - Cemex mine solar, conceptual design. Primary for a 9.9 MW mine plant still at conceptual design, and for the company's statement that the plant would lift own renewable production to 16.5 GWh a year. 16.5 minus 8.4 equals 8.1, and 8.4 divided by 145 is about 5.8%, and 8.4 divided by 6.377 is about 1.32 GWh per MW, and another 17 GWh at that rate is about 12.9 MW, and 6.377 plus 12.9 is about 19.3 MW: all of that is our arithmetic. None of those derived figures is printed as a Cemex total.
