980 MW of new combined-cycle capacity for CFE on the Bajío grid — delivered alongside Mitsubishi Power's commissioning team, every plant-level test, COD into the regional grid.
CCC Salamanca is a 980 MW combined-cycle plant in Salamanca, Guanajuato, built by a consortium of Mitsubishi Power and Técnicas Reunidas for the Comisión Federal de Electricidad.
The plant sits in the Bajío — Mexico's industrial heartland, with high concentrations of automotive, chemical and electronics manufacturing — and was commissioned specifically to strengthen the regional grid as load growth in the Bajío continued to outpace local generation capacity.
Grid Code Engineering delivered the plant-level (Level 02) and operational (Level 03) testing program alongside Mitsubishi Power's commissioning organization. The engagement is one of three GCE has delivered for Mitsubishi-commissioned combined-cycle plants in Mexico across the 460–980 MW range.
Level 01 (per-unit generator-terminal characterization) was within the OEM commissioning organization's scope. GCE's independent scope began at the POI and at the plant-level performance boundary.

Voltage and frequency regulation at the POI, primary frequency response, electrical-protection coordination, ride-through behavior, and POI-level reactive capability at full plant output.
Performance under ASME PTC, reliability demonstration, full startup and shutdown sequence characterization across the combined-cycle thermal cycle.
The defining challenge on Salamanca was the operational stake of the regional grid. The Bajío's load is concentrated in industrial demand that responds sharply to disturbances — voltage sags propagate, frequency excursions stress the protective relaying across multiple substations.
The grid code testing campaign had to be sequenced inside CENACE (Mexican Grid Operator) operational dispatch with enough lead time that any test-induced disturbance was contained, but with enough campaign density that the COD milestone wasn't pushed.
This is the kind of project where the value of the OEM commissioning organization and the independent grid-code team being in lockstep becomes visible. Mitsubishi Power handled the equipment side; GCE handled the regulator-facing side; the two teams moved in tight coordination around CENACE's dispatch windows.
The plant achieved commercial operation on schedule. The grid-code dossier passed CENACE review and the plant entered commercial operation as planned, providing dispatched capacity to the Bajío region from its first dispatch hour.
CCC Salamanca is one of the larger thermal additions to the SIN in the last several years.
