Dominican Republic Launches 600 MW Renewable Energy Tender

Background and Context

The Dominican Republic has officially initiated a landmark 600 MW renewable energy tender, marking a significant evolution in its procurement strategy by mandating the inclusion of battery energy storage systems (BESS). Managed by the Unified Council of Distribution Companies (CUED), the initiative aims to transition renewable generation from intermittent supply to a reliable, dispatchable baseload power source. This move aligns with global trends where grid stability is becoming as critical as generation capacity, particularly as countries look to reduce reliance on fossil fuel-based thermal plants.

Key Details

The tender process saw robust interest, with 32 companies participating in the initial credential submission event. The scope covers project capacities ranging from 20 MW to 300 MW, utilizing both wind and solar technologies. A defining feature of this procurement is the 15-year supply period, with projects required to commence operations within 24 months of contract signing. The energy generated will be distributed among three primary utility companies: Edenorte (30%), Edesur (35%), and Edeeste (35%). According to CUED President Celso Marranzini, the integration of storage is designed to enhance system reliability and operational efficiency across the national grid.

What This Means for EPCs and Developers

For EPC contractors and developers, this tender underscores the necessity of technical proficiency in hybrid energy systems. As global battery storage costs continue to decline—with prices for four-hour BESS dropping below $100/MWh in several markets as of 2025—the economic viability of storage-backed renewables has reached a tipping point. Contractors must now pivot from pure-play solar or wind expertise to integrated project management that includes BESS procurement, installation, and long-term maintenance. The ability to manage complex grid-integration requirements will be a key differentiator for firms bidding on such large-scale international projects.

What Happens Next

The next phase will involve the evaluation of technical and financial bids from the 32 participating entities. With global installations of long-duration energy storage systems having surpassed 15 GWh in 2025—a 49% year-on-year increase—the market is well-positioned to meet these requirements. This development serves as a critical case study for the India renewable energy sector, which is increasingly exploring similar hybrid tenders to manage grid variability and achieve round-the-clock (RTC) power supply goals. As India continues to scale its own storage-linked auctions, the lessons learned from the Dominican Republic’s procurement structure regarding system stability and cost-competitiveness will be highly relevant for domestic stakeholders.
