Falcon Dam is an earthen embankment dam on the Rio Grande between Starr County in the U.S. state of Texas and the city of Nueva Ciudad Guerrero in the Mexican state of Tamaulipas. The dam was built for water conservation, irrigation, hydroelectric power generation, flood control, and recreational purposes and as an international border crossing between Zapata and Starr Counties and Tamaulipas. Construction on the dam began in December 1950 and ended in April 1954, but it was dedicated by Mexican President Adolfo Ruiz Cortines and U.S. President Dwight D. Eisenhower in October 1953.

No wholesale contracts disclosed in FERC EQR for this plant.
FERC EQR captures bilateral wholesale energy + capacity contracts ≥$1M/yr filed quarterly by jurisdictional sellers — covers renewable PPAs, thermal energy sales agreements, capacity contracts, and tolling agreements alike. Many plants don't appear: regulated-utility output flows to ratepayers via cost-of-service rather than bilateral contracts; small projects fall below the filing threshold; tax-equity-financed renewables route offtake to investors not utilities; merchant plants sell into ISO clearing markets without bilateral contracts. News-extracted buyer facts (below) may surface contracts disclosed only through announcements.
