The utility regulator wants the Instituto Costarricense de Electricidad to make plans for exporting power during the rainy season.
The regulator, the Autoridad Reguladora de Servicios Públicos, said that the country sold $3.6 million in power last year and managed to save $44 million by importing cheaper power during the dry season and saving on oil-fired generation.
The countries of the region have formed the Mercado Eléctrico Regional to trade power back and forth.
Costa Rica has an advantage because it generates excess power during the rainy season and is expected to have more surplus when the Reventazón hydro plant goes into operation next year, noted the regulator.
A response from the power generator is expected, the agency said.
