LUMA and AES Puerto Rico energized a new 115-kilovolt transmission line connecting the Jobos Solar and Jobos BESS projects to Puerto Rico’s grid. Testing will begin for the island’s first utility-scale BESS ahead of commercial operations in Q4 2026. The projects add 80 MW of solar and 110 MW of four-hour storage (about 440 MWh). Solar generation is enough for the equivalent of ~25,000 homes, peaking near ~40,000 at midday. Project Marahú, backed by over $860 million in U.S. DOE support, includes the Jobos projects.

ABOUT

What is Fimmer?

Most feeds treat all company headlines the same. An executive interview, an office closure, stock analysis, and a data breach can sit side by side with no sense of scale. Fimmer ranks coverage by what matters, so important events stand out and signals are prioritised over noise. We cluster related company news and score each story using a range of metrics, so you see the most crucial stories first.

SCORING

What do the scores mean?

Significance (0–10) measures the scale of the real-world impact. Sentiment and ESG (−10 to +10) indicate the tone of the coverage and whether the change relates to environmental, social, or governance factors. Together, these scores help distinguish meaningful developments from routine company news. More information about our scoring methodology can be found on our About page.
