Proposal for Deployment of a 250MW Mobile Power Plant in the Dominican Republic
Executive Summary
Geodyn Solutions, a leader in modular mobile power generation, proposes to partner with its statistical optimization partner to deploy a 250MW LNG-based mobile power plant in the Dominican Republic. This project provides a flexible, rapid-deployment solution to stabilize the grid, meet rising electricity demand, and support industrial and tourism-driven growth.
The configuration integrates advanced modular turbine systems with a heat recovery steam turbine (HRST) and an Organic Rankine Cycle (ORC) for waste heat utilization. This boosts efficiency to ~58%, ensuring fuel savings and emission reductions.
The project assumes a PPA tariff of $0.17/kWh with a 15-year lifespan, delivering strong returns, rapid payback, and long-term profitability.
