Two power stations switching on would pass without comment in most markets. The disclosures that reached the Saudi Exchange on Thursday are worth reading as a measurement of machinery: Taiba 1 in Madinah and Qassim 1 in Al-Qassim, awarded to a Saudi Electricity Company and ACWA Power alliance in October 2023, are now selling power, less than three years after award. Between them, 2,555 megawatts of an eventual 3,800 or so have come onto the grid before either plant is finished.
The confirmed facts are these. The two project companies, Sidra First Electricity Company for Taiba 1 and Qudra First Electricity Company for Qassim 1, received initial commercial operation certificates for key generating units: 1,272 megawatts at Taiba out of a planned 1,934, and 1,283 megawatts at Qassim out of 1,896. Both are combined-cycle gas plants. ACWA Power and Saudi Electricity each hold 40 percent of each company, with Haji Abdullah Alireza and Co. holding the balance, and both developers say the financial effect begins in the fourth quarter of 2026. Full commercial operation is scheduled for next year.
The structure behind those certificates explains the speed. Both plants sell their entire output to the Saudi Power Procurement Company under 25-year power purchase agreements signed in November 2023; financial close followed in May 2024 at a combined SR11.4 billion ($3 billion). The single-buyer model turns generation into a repeatable product: the developer consortium carries construction risk, the procurement company carries offtake, and revenue starts the day a certificate lands rather than the day the ribbon is cut. Staged commissioning, with gas turbines earning in simple-cycle mode while the steam halves are completed, is written into the design. The result is two-thirds of the capacity earning months before completion, an arrangement that suits a fast-growing grid and an investor with capital costs to recover in equal measure.
The choice of fuel is doing separate work. Combined-cycle gas units displace the crude and fuel oil that older stations burn through summer peaks, and every barrel released from a boiler is available to export or refine. The expansion of domestic gas supply gives the new fleet a feedstock that does not compete with the export ledger. The power build and the upstream gas program are two ends of one substitution.
Demand is the reason the cadence matters. Electricity load in the Kingdom is compounding from several directions at once: a single artificial-intelligence data-center agreement signed this month specifies 250 megawatts on its own, new industrial capacity is taking shape at the coastal cities, and the summer cooling peak grows with the population. Against that arithmetic, 2,555 megawatts is roughly ten of those data campuses, arriving in time for next summer rather than the one after. The grid is the quiet constraint under most of the programs the Kingdom has announced this year; capacity landing early is what keeps it quiet.
The next reading comes from the procurement rounds stacked behind this one. Taiba 2 and Qassim 2 have already reached financial close under a separate consortium, and later rounds will be priced against this week’s evidence that the model delivers on its staging. Watch the remaining units at both sites through 2027, and watch whether the procurement company’s next tenders shorten the interval between award and first power again. In a power market, that interval is the real product.
