Energy storage in the Dominican Republic has moved beyond future discussions and become one of the most competitive segments of the regional energy market. However, amidst the massive influx of manufacturers and developers into the BESS business, Pylontech warns that the main bottleneck will no longer be the technology itself, but rather the technical capacity to execute projects correctly.
“There are very few EPC contractors who are truly prepared and experienced to execute projects,” said Victor San Román , Field Application Engineer at Pylontech, during his participation in FES Caribe.
“There is a lot of uncertainty, even sometimes in the design and financial analysis phases,” he warned, explaining that the challenge is no longer just about incorporating batteries into the electrical system, but about developing projects capable of meeting criteria of stability, safety, bankability, and long-term operation.
In that context, the executive believes that the professionalization of the sector will be one of the most decisive factors for the growth of energy storage in the Dominican Republic.
The warning is particularly relevant given the rapidly growing volume and regulatory complexity of the Dominican market. The Dominican Republic recently passed Resolution SIE-092-2025-LCE, which established technical and regulatory conditions for renewable energy projects with storage, while the latest tender awarded 325 MW under a scheme that incorporated batteries and the provision of ancillary services.
In addition, the country is preparing a new series of calls for proposals for photovoltaic parks in operation and new developments with storage, in a package that could exceed 800 MWh in the short term.
According to Pylontech, this scenario is starting to raise the level of technical and financial requirements for all actors involved in the BESS business in the Caribbean.
“The market is booming right now, flooded with different options and manufacturers who look at them on paper and say, ‘everyone’s doing the same thing,’” San Román noted. However, the executive believes the real differentiator will emerge from the ability to guarantee operational safety, technological control, and execution experience.

“Our advantage is that we are a fully vertically integrated manufacturer,” he explained. He detailed that Pylontech develops solutions ranging from small 12V applications to utility-scale systems, integrating everything from cell manufacturing to the complete storage system.
The Latin American market has undergone rapid transformation in recent years, with energy storage evolving from a niche technology to an increasingly in-demand component of electrical systems. In this process, the executive highlighted the evolution of the Dominican market compared to other countries in the region.
“Here in the Dominican Republic, it seems much more mature compared to other countries. There is greater knowledge and people know what they want to install,” he said.
For Pylontech, part of this evolution also requires manufacturers to accelerate their technological developments and safety standards. In this regard, 33% of the company is dedicated exclusively to research and development (R&D).
The company claims that this investment allowed it to position itself among the manufacturers with the largest market share globally in different storage segments.
“We have been the manufacturer with the largest market share worldwide in different markets,” the executive stated.
For San Román, this capability is especially relevant at a time when BESS projects are beginning to demand higher standards of reliability and operational safety. “Pylontech has never had any incidents in any project, whether residential or commercial and industrial,” he stated.
While the Dominican Republic accelerates new tenders and consolidates an increasingly sophisticated storage market, the company maintains that the next competitive filter will not be solely economic.
“We don’t want to sell something just by saying it’s been installed, because the reputation of the projects is very important to us,” San Román concluded.
