Costa Mar's power margins tighten as reservoir levels drop

The Esperanza reservoir, which feeds Costa Mar's hundred-percent renewable grid, stood at 62 percent capacity on Wednesday morning, down from 71 percent on the same date last year. The Federal Hydro Authority released the figure alongside a revised forecast for the dry season, warning that if July precipitation remains below the historical average, export commitments to Tierra Verde may need to be curtailed by mid-August.

The squeeze comes at a moment of acute political sensitivity. Tierra Verde's own hydroelectric output has declined due to drought conditions along the Río Esperanto, leaving the region dependent on Costa Mar's surplus power. A reduction in exports would ripple through federal energy markets and test the cooperation framework that has underpinned the Republic's power-sharing agreements since 1995.

Governor Solomon Adeyemi convened the Marine and Energy Ministry on Wednesday to review contingency protocols. The Ministry's director, speaking on background, said the region faces a choice between maintaining export volumes at the cost of tighter domestic margins, or prioritizing internal supply security and negotiating reduced commitments with Meridian.
