Bringing clean power to the Caribbean

Print

A major sustainable energy transition is happening in the Caribbean. Heavy fuel-based economies and vulnerability to extreme weather see the region pushing for greater resiliency and energy security. Upgrades to existing infrastructure are supporting the increased demand for energy capacity brought by tourism. So is the case off the northern cost of Honduras on the island of Roatan, where a robust sustainable energy investment strategy is accelerating the region’s clean energy transition. The modernisation of the local Roatan power system via the integration of renewables and flexible generation has already delivered long-term economic growth for a population of approximately 60,000 inhabitants.

Wärtsilä’s solution is an energy upgrade—including a new 10 MW / 26 MWh energy storage system and advanced control platform—that introduced flexibility into the local Roatan grid. While the batteries secure reliability by eliminating the need for mechanical spinning reserve, Wärtsilä’s sophisticated GEMS energy management software controls Roatan’s entire energy system, including enhancing earlier delivered Wärtsilä engines and solar panels. GEMS provides data visibility into the entire system, including load forecasting, and has enabled the optimisation of the (load) data and system assets. GEMS also enable the further integration of intermittent and variable solar and wind resources into the existing grid.
