Notes on why certain decisions are never truly finalized, what shifted once the entire system could be mapped, and what it means to institutionalize a function rather than simply provide an answer.

Whoever tenders by time blocks may pay for the evening at the midday price
In 2025, Chile tendered the energy for its regulated customers in 3 time blocks and awarded all 3 at USD 64.5/MWh. The rules of tender 2025/01 separated night, from 23:00 to 07:59; solar, from 08:00 to 17:59; and evening peak, from 18:00 to 22:59. The Comisión Nacional de Energía (CNE) received 708 offers, 3.9 times the energy requested. It awarded 100% to 1 generator, at USD 64.5/MWh in each block, on the lowest present value of the offered prices and their indexation. Price
For the buyer, the cheapest MWh and the cheapest critical hours may differ
Firmness mechanisms exist in the 7 countries reviewed. Contracting energy and covering critical hours should be evaluated together. Those mechanisms — capacity, backup, replacement — vary from country to country. In Peru, in the May 2025 to April 2026 tariff, the reserve, capacity, and reliability charges add up to PEN 10.1 per kW per month. The renewable premium adds up to 7.1. Those charges pay for system backup, and their attribution to renewables remains unproven. The pro
The Dominican 200 MW battery tender closes registration on November 11
The Consejo Unificado de las Empresas Distribuidoras groups EdeNorte, EdeSur, and EdeEste, the Dominican Republic's 3 electricity distributors. On November 2 it signed the notice of tender EDES-GER-SAEB-01-2026. The Superintendencia de Electricidad, which the notice names as supervisor of the process, authorized it through resolution SIE-141-2026-LCE of October 29, 2026. The purpose is to buy long-term energy backed by new battery energy storage systems, for up to 200 MW and
Midsize banks may have inherited their judgment, and they decide with less margin for error
Mexico's 16 midsize banks operate with less scale than the large ones, and a coordination error among the areas that decide their balance sheet would weigh more heavily on their results [H]. We start from a premise that public figures do not prove: midsize banks have the committees that decide the balance sheet—assets and liabilities, pricing, risk— [H] (section 7). Over the past year, 12-month return on equity (ROE) fell at 13 of the 16 [D]; the average liquidity coverage ra
The contract pays for energy; the system charges for the hour when it is missing
Evidence markers: [V] verified in a primary source · [D] derived by calculation · [E] estimate with explicit assumptions · [H] hypothesis pending testing Contracting energy and covering demand in critical hours are decisions that must be evaluated together. The 7 countries examined have mechanisms for recognizing, contracting, or remunerating firmness (§1). For this note, firmness means a resource’s accredited contribution under critical conditions; each country uses its own
