Project Highlights
- Reservoir-to-wire (R2W) technology enables fuel gas directly from local wells through onsite gas treatment unit into gas turbine generator (GTG).
- Plant design accommodates future heat recovery steam generator (HRSG), steam turbine generator (STG), and cooling tower for simple cycle to combined cycle conversion.
- Plant design considers modular design wherever possible due to remote location in Amazon jungle.
Project Description
The project consists of a complete 1×1 combined cycle (590 MW) and 1×0 simple cycle (360 MW) gas turbine facility utilizing gas from the nearby Azulão field in the Amazon Basin. The plant includes onsite natural gas treatment, producing an average of 4.3 MMNM3/day of natural gas and 350 M3/day of condensate. The simple cycle design provides for expansion in the future to a 1×1 combined cycle.
The GE power island consists of two GTGs, one HRSG with bypass stack, one STG, and the overall plant control system. The plant features a mechanical-draft wet cooling tower for heat rejection, with makeup raw water provided from the Urubu River via a new pumphouse.
Project Scope
Sargent & Lundy is serving as owner’s engineer for Eneva to provide basic engineering and early procurement support for the Azulão large-scale, advanced-class power plant in Amazonas, Brazil. Support also includes engineering, procurement and construction contract development, site development, review of original equipment manufacturer documents, and detailed design of major foundations.
The scope also includes a new 500‑kV switchyard, 11‑km‑long 500‑kV transmission line, and an extension added to the existing Silves substation, with Sargent & Lundy’s Electric Grid Infrastructure Services group providing owner’s engineering support.
