| engineering · 2026-06-06 A data agent with real identity: end-to-end OAuth On-Behalf-Of over Microsoft Fabric Almost no "chat with your data" demo answers the key question: whose permissions does the agent query with? How we built a production data agent for a Spanish energy company where every question travels with the user's identity all the way to the lakehouse — one MCP server, three clients (M365 Copilot, Claude, VSCode), and OAuth 2.0 On-Behalf-Of preserving RLS end to end.

| analysis · 2026-06-06 From days to minutes: ask your data in plain language In most companies, answering a business question with data takes days: ticket, analyst, query, Excel. How a Spanish energy company cut it to minutes — any employee asks in their own language, from Teams or Claude, and gets the answer with their own permissions. No new passwords, no bypassing governance. Read case | https://datons.com/blog/from-days-to-minutes-ask-your-data |
| analysis · 2026-05-26 Besós and San Roque: same owners, opposite outcomes Two Spanish CCGT complexes share the same Endesa/Naturgy ownership split — and produce opposite results under Operación Reforzada. In Barcelona, Naturgy's unit wins; in Cádiz, Endesa's dominates. The difference is geography: mixed clusters reward the operator, uniform clusters reward the location.

| analysis · 2026-05-22 Who pockets the hidden RT3 cost: €3,900M of pay-as-bid concentrated in 5 utilities Twelve months after the Iberian blackout, the pay-as-bid Spain pays its CCGT fleet for solving day-ahead technical constraints (consumer-side RT3) is €3,870M per year. Three groups absorb 62% of the flow. Iberdrola is the marginal winner (+€152M post vs pre); Endesa, the only major loser (-€100M).

| analysis · 2026-05-22 Operación Reforzada at unit level: which CCGTs win and lose the redispatch Drilldown to the plant level: post-blackout pay-as-bid for solving technical constraints does not reward all combined-cycles equally. Within the Besós complex in Barcelona, unit 4 (Naturgy) gains €28M while unit 5 (Endesa) loses €71M — same site, two owners, opposite trajectories. The cluster pattern: south (Cádiz/Huelva) all winners, north interior all winners, Mediterranean coast and SE mixed. Read case | https://datons.com/blog/spain-blackout-rt3-winners-by-unit |
| analysis · 2026-05-17 RT3, the hidden cost of integrating renewables in Spain's grid: ×10 since 2020 Spain's technical-constraints cost (compodem RT3) has multiplied tenfold since 2020. Quantitative analysis over 148 months: Pearson correlation +0.76 with the share of variable generation (PV + wind), controlled for OMIE wholesale price. Corroborated by PwC's February 2026 report on the post-blackout Reinforced Operation. Read case | https://datons.com/blog/spain-tertiary-reserve-cost-renewable-penetration |
| analysis · 2026-05-17 12 months after the Iberian blackout: the system absorbs the same, pays differently 365-day pre vs 365-day post-blackout comparison across five dimensions: the Iberian power system absorbs the same renewable share, but the cost of technical constraints (compodem RT3) has multiplied by 2.5 and negative-price hours by 4.4 — driven by REE's post-blackout Reinforced Operation.
