| Technical details / open items | Eight 3516E engine/product identities appear in the technical package, with machine-build dates from October through December 2024. The reviewed generator-set nameplate is dated February 2025.; Reviewed nameplate: 3,000 kW / 3,333 kVA, 0.9 PF, 480 V, three-phase, 60 Hz, 4,009 A and 1,800 RPM; wye series, six leads, Class H insulation.; Reviewed factory-order example: 3516E HPD, 3,000 ekW standby with fan, EMCP 4.2B controller, 5,000 A IEC busbar with top cable entry, AF81AVS radiator and dual electric starting.; That factory-order example specifies two 35 A battery chargers, no batteries ordered, no factory circuit breaker, non-UL-2200-listed package, no CSA selection and no seismic certification selection. Panel and decal selection is Portuguese. Match the actual order record to each selected unit.; Emissions records identify the 2024 engine family as EPA Emergency Stationary, constant speed. This is not a claim of prime/continuous duty or of suitability for a particular site's emissions permit.; The documented 3 MW rating is standby. A proposed lower output or duty change, including 2.75 MW operation, needs the selected-unit OEM/dealer rating and emissions review; no continuous rating or automatic conversion is promised. | Caterpillar G3520K K-Series, 20-cylinder natural gas engines; 2,500 ekW / 3,125 kVA each at 0.8 power factor, 60 Hz, 480 V.; Skid-mounted generator sets supplied without individual enclosures. Five equipment buildings are specified, each housing 20 generator sets.; One Safety Power ecoCUBE SCR system per generator set. Emissions configuration and permit suitability are reviewed for the specific project location.; Balance of plant: two GE 13/115/230 kV step-up transformers, one 3,200 A load bank, two main switchgear lineups and ten sub-line lineups, plant controls and protection, and 20 chiller-cooler units.; The intermediate step-up from 480 V, medium-voltage collection, transformer MVA ratings and final one-line are established in the project engineering scope.; Installation, commissioning, testing and documentation are included within the agreed EPC scope. Site responsibilities, exclusions and warranty terms are set out in the definitive written agreement.; All 100 generator sets and supplied balance-of-plant equipment are specified for readiness within 90 days of deposit received in escrow. This is the equipment readiness milestone; the installation schedule follows site review.; Contact Tommy Marco for the technical package, inspection arrangements, project scope and commercial terms. |
