Energy expert warns of aging power plants' risks amid rising renewable energy demand

In a recent meeting held by the Cámara de Representantes in Puerto Rico, discussions centered around the operational challenges faced by the island's aging power generation infrastructure. The focus was on the limitations of traditional thermal power plants, particularly in the context of increasing renewable energy sources.

The meeting highlighted that many existing thermal plants were designed to operate at or near maximum capacity, with minimal fluctuations. This design is problematic as the demand for electricity during the day has been decreasing due to the integration of more renewable energy sources. As a result, operators are often required to reduce output from these older plants, which can lead to mechanical failures and increased wear on the equipment.

One key point raised was the detrimental impact of frequently lowering and raising power generation levels. Experts noted that this cyclical operation can damage the boilers of thermal plants, which were not built to handle such variability. The ongoing shift towards renewable energy is exacerbating this issue, as demand patterns change and operators struggle to manage the transition effectively.

To address these challenges, the meeting underscored the need for technological upgrades. Suggestions included the adoption of newer technologies such as combustion turbines and battery storage systems, which can better accommodate the fluctuations in energy demand without compromising equipment integrity. However, transitioning to these advanced systems is not an immediate solution and could take several years to implement.

The discussions reflect a critical juncture for Puerto Rico's energy sector, as the island grapples with the dual challenge of maintaining reliable power generation while integrating more sustainable energy sources. The path forward will require significant investment in new technologies to ensure a resilient and efficient energy system that can meet the evolving demands of the community.
