The Dominican Republic’s Unified Council of Distribution Companies (CUED) held the credential submission event for a public tender for up to 600 MW of new renewable generation, which, for the first time, includes energy storage as an essential component of the projects.

The event witnessed participation from 32 companies.

The tender seeks to procure new wind and solar generation combined with storage systems, with project capacities ranging from 20 MW to 300 MW.

The supply period will be 15 years, starting within 24 months after contract signing. The energy will be supplied among electricity distribution companies Edenorte (30%), Edesur (35%), and Edeeste (35%).

Celso Marranzini, President at CUED, highlighted that the incorporation of energy storage will allow renewable sources to function as baseload power, strengthening system stability and the reliability of the national electricity supply. “I am seeing strong participation that will definitely improve the situation of the distribution companies, especially with batteries,” he said.

He noted that integrating energy storage not only improves system stability and reduces dependence on fossil fuels but also makes renewables a continuous, dispatchable energy source, resulting in greater energy security and operational efficiency for national power systems.

Global battery storage costs have declined sharply, reaching record lows in 2025, according to BloombergNEF. The benchmark cost of a four-hour battery energy storage system fell significantly year-over-year, with prices dropping below $100/MWh in several markets.

The decline has been driven by lower battery pack prices, improved supply chains, and increased manufacturing scale, making storage-backed renewable projects increasingly cost-competitive and accelerating their adoption in large-scale tenders.

Global installations of long-duration energy storage systems surpassed 15 GWh in 2025, a 49% increase from the previous year. The capital cost for long-duration (4 hours or more) utility-scale battery energy storage systems in markets outside China and the U.S. reached roughly $125/kWh by October 2025.
