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 800 MWh in a single block. That is 4 hours at full power, by our own calculation.
The schedule leaves 2 windows, and the first closes this week.

Registration stayed open 9 days and costs USD 5,000, or the equivalent in Dominican pesos at the Central Bank rate. Between the close of registration and the receipt of bids, 65 days pass, by our own calculation. Any party that fails to register by November 11 is shut out of a 15-year contract, and the notice offers no second window.
The size rule decides who may compete. The notice sets a minimum net nominal capacity of 4 MW per bid and a maximum equal to 50% of the concessioned capacity of the plants currently under contract. The 2 conditions compound. A plant needs 8 MW of concessioned capacity for its half to reach the 4 MW floor, by our own calculation. Filling the 200 MW block requires at least 400 MW of concessioned capacity among the plants that register, also by our own calculation.
The eligible universe is narrower than the country's renewable fleet. The Ministerio de Energía y Minas reports 1,717 MW of solar photovoltaic and 483 MW of wind capacity installed in the national power system as of May 2026. They add to 2,200 MW, by our own calculation. The 400 MW the block requires equals 18.2% of that figure, by our own calculation. The comparison measures the order of magnitude rather than the eligible roster. The notice caps a bid against concessioned capacity, and the ministry reports nominal installed capacity. These are 2 different measures. The notice also requires 3 cumulative conditions. The plant must exist and be non-dispatchable renewable, must hold a long-term supply contract in force with the distributors at the time of registration, and must not have batteries today.
Our reading is that the 50% rule sets the size of the universe before it sets the price. Any party deciding whether to register a plant this week commits capital for 192 months, the 12 of start-up plus the 180 of contract term, by our own calculation. That party also decides with the tender documents, which download only after paying the registration fee.
A renewable portfolio Decision System treats the 50% rule as the filter that ranks a company's own plants before it estimates the bid price.
