The energy transition in Latin America and the Caribbean faces a key challenge: fragmented regulatory frameworks that hinder regional integration and investments. While some countries innovate in standards for renewables and flexible markets, others maintain more rigid schemes. This space will analyze whether it is possible to build shared standards – in interconnections, capacity remuneration or green hydrogen – without losing national energy sovereignty. What lessons can be taken from experiences such as European or Central America? The debate will look for practical ways to harmonize regulations and accelerate a just transition in the region.
