Drought and fire test Costa Mar's hundred-percent hydro grid

The Río Esperanto hydroelectric complex sits in the inland hills above Puerto Azul, a series of dams and reservoirs that have supplied Costa Mar with one hundred percent of its electricity since the region's founding in 1994. The system was built on the assumption of consistent rainfall and seasonal water flow. This summer, that assumption is breaking down.

Reservoir levels at the three main collection points have fallen to seventy-two percent of capacity, the lowest mark in the system's thirty-year operating history. The Federal Hydro Authority, which manages Costa Mar's power exports to Meridian and the other regions, has begun rationing exports and warning of possible rolling blackouts if the dry season extends beyond its normal October end date.

The drought has also triggered a secondary crisis: wildfire risk in the upland forests that feed the reservoirs. Two significant fires in the past month have forced evacuations in the inland towns of Monteverde and San Isidro. The fires themselves have not yet reached the watershed, but smoke and ash have degraded water quality in the collection reservoirs, requiring additional filtration and slowing the power-generation cycle.
