Each row is the deepest code carrying data, because a whole division is credited with everything beneath it and would take the list. ## What the notices look like Utility procurement mixes commodity supply with heavy engineering: fuel and electricity purchase on one side, transformers, grid works, generation equipment and long maintenance contracts on the other, often under utilities rules with their own higher thresholds. ## Where these buyers are mapped deepest - Algeria: 14 of this type, 24 sources mapped (https://trinta.ai/government-tenders/algeria) - Bangladesh: 13 of this type, 27 sources mapped (https://trinta.ai/government-tenders/bangladesh) - India: 13 of this type, 27 sources mapped (https://trinta.ai/government-tenders/india) - Bolivia: 11 of this type, 18 sources mapped (https://trinta.ai/government-tenders/bolivia) - Greece: 11 of this type, 16 sources mapped (https://trinta.ai/government-tenders/greece) - Botswana: 10 of this type, 30 sources mapped (https://trinta.ai/government-tenders/botswana) - Azerbaijan: 9 of this type, 16 sources mapped (https://trinta.ai/government-tenders/azerbaijan) - Bosnia and Herzegovina: 9 of this type, 19 sources mapped (https://trinta.ai/government-tenders/bosnia-and-herzegovina) ## Frequently asked questions **Which CPV codes cover energy tenders?** Energy procurement runs under CPV division 09, petroleum products, fuel, electricity and other sources of energy, with division 31 for electrical machinery and equipment, 65 for public utilities and 76 for services related to the oil and gas industry. Grid and plant construction also appears under the construction divisions, which is why energy suppliers usually watch both slices. **Do state energy companies publish on the national portal?** Often only partially. Across the countries TRINTA maps, state-owned enterprises are the single largest category of buyer publishing on their own sites rather than through the central channel, and utilities are the heart of that category. In several markets the national electricity, water or fuel company is the most regular publisher in the country and never appears in a portal-only watch. Sector buyers mapped outside the national portals: 392. ## How contested it is, measured in Portugal - 7.3% of open procedures drew a single bid - 4.8 bids on average - 466 open procedures behind these figures - CPV 09, Petroleum products, fuel, electricity and other sources of energy: 7.4% single bid across 299 procedures - CPV 31, Electrical machinery, apparatus, equipment and consumables; lighting: 7.2% single bid across 167 procedures Portugal publishes its complete contract register as open data, so competition is counted there rather than estimated. These are Portuguese figures for January to July 2026, covering only open procedures whose bidder list was reported; direct awards are excluded, because there the buyer chooses who bids.
