Puerto Rico kicked off 2025 with a harsh reminder of its fragile power grid. On New Year’s Eve, nearly the entire island – 90% – lost electricity, leaving over 1.3 million customers in the dark during holiday celebrations. Power was restored on January 1, but the blackout underscored an urgent need for reliable energy solutions.

In a move to help bolster Puerto Rico’s grid resilience, Convergent Energy and Power secured a conditional commitment from the US Department of Energy (DOE) Loan Programs Office for a massive solar and battery storage initiative in December. The DOE’s backing includes up to $559.4 million in loan guarantees, paving the way for Convergent to install both solar and standalone battery systems across the island.

A new study published in the journal Renewable Energy uses data from the state of California to demonstrate that no blackouts occurred when wind-water-solar electricity supply exceeded 100% of demand on the state’s main grid for a record 98 of 116 days from late winter to early summer 2024 for an average (maximum) of 4.84 (10.1) hours per day.

Trina Solar has sold its Texas solar panel factory as the US scrutinizes Chinese companies cashing in on Inflation Reduction Act tax breaks.
