Off-grid Brazil: extending beyond isolated communities

The Brazilian power grid reaches approximately 99% of the country’s population. To connect the remaining 1% has been challenging – often located in isolated communities of regions that are difficult to reach. With increasing global adoption of solar+storage, and significant price drops across the two technologies over the past decade, the solution is showing promise for the remote Brazilian market. Solar+storage is becoming a more competitive solution than its most popular alternative – diesel – to supply the needed power for off-grid communities. And now, even grid-connected residential properties are opting for independence.

Battery storage steps in to support renewable targets on French islands

France’s Energy Transition Law has set forth aggressive renewable targets with plans to achieve energy independence by 2030 for its Non Interconnected Areas (NIA), or small isolated electricity networks. The renewable targets for its primarily overseas regions are more ambitious than the country’s mainland energy transition goals, with the national plan aiming to achieve 50% renewable energy penetration for NIA electricity by the end of this year. The rapid deployment of solar PV on the country’s islands across international waters creates challenges for grid operations, and battery storage is stepping in as a solution.

PPA signed for solar-wind-storage microgrid on Saint Helena

Pash Global, a subsidiary of multinational commodities trader Trafigura Group, has signed a renewables power purchase agreement for a project on the British overseas territory of Saint Helena. The microgrid will help the South Atlantic island’s aim of investing in renewables, reducing diesel dependence and increasing fuel security and price stabilization.
