The week ahead

Across the 15 operational solar plants we track (12,253 MW), the irradiance forecast implies 487 GWh over the next seven days, 2.5% below the long-run normal for these dates. The strongest day is Tuesday 29 September, the weakest Saturday 3 October. Peak temperature reaches 41.4°C in Riyadh, 34.6°C in Jeddah, 43.8°C in Dammam. Cooling demand rises with it.

The Saudi power balance

Operational renewable capacity stands at 12.7 GW, 9.7% of the 130 GW target for 2030, with 70.3 GW tracked across every stage. Reaching the target needs 35.2 GW a year from here. Everything currently in construction and tender delivers 17.3 GW a year if it all lands on time. The pipeline is a snapshot that grows with each tender round, so these are two rates as they stand today, not a projection of the outcome. The Principal Buyer's register and the tracker record a different stage for 5 of 38 matched projects, including Haden at 2000 MW, Muwayh at 2000 MW, Al-Ghat at 600 MW. The figures above count the register's stage, because the Principal Buyer contracts the power and signs off commercial operation; that moves 5,500 MW between stages against the tracker's own reading, which stays published beside it so the correction can be checked.

Low-emission hydrogen, announced and running

The IEA's project map carries 99,150 kt a year of announced low-emission hydrogen capacity worldwide, across every stage from concept to operating. 1,349 kt a year of that is operating, 1.36% of the total; 5,321 kt has taken a final investment decision or is under construction, and the rest sits at feasibility study or concept. Saudi projects account for 1,246 kt a year, 1.26% of the world total, of which 373 kt is past final investment decision. Capacity is counted in the year each project enters the map and the map is republished once a year, so these are the announcements as the IEA last recorded them, not a rate of delivery.
