Cape Verde Government and TotalEnergies Partner on Sal Island Cape Verde microgrid
In a significant step towards energy independence and sustainability, the government of Cape Verde has partnered with global energy company TotalEnergies to develop a state-of-the-art hybrid microgrid on Sal Island. This ambitious project marks a pivotal moment in the archipelago’s journey to reduce its reliance on imported fossil fuels and embrace a cleaner energy future.
The partnership, formalized through a memorandum of understanding (MoU) signed in late 2024, sets the stage for a transformative energy initiative on one of Cape Verde’s most vital tourism hubs.
A Strategic Move for Energy Security with the Cape Verde microgrid
As a Small Island Developing State (SIDS), Cape Verde faces unique energy challenges, importing over 90% of its energy resources. This dependency creates vulnerability to global price fluctuations and supply chain disruptions. The Sal Island microgrid project directly confronts this issue by localizing power generation and integrating renewable sources.
The project is a cornerstone of Cape Verde’s 2025–2030 National Energy Plan, which aims to achieve 50% renewable energy penetration by 2030 and reach net-zero emissions by 2050. This collaboration with TotalEnergies builds on previous successes, such as the 5 MW solar plant on the island of Boa Vista, demonstrating a continued commitment to sustainable development.
Inside the Sal Island Cape Verde microgrid Project
The initiative is designed to provide stable, clean, and reliable power to Sal’s approximately 20,000 residents and the millions of tourists who visit annually.
Key Project Details:
- Technology: The microgrid will feature a hybrid system that intelligently combines solar photovoltaic (PV) panels with a battery energy storage system (BESS). Existing diesel generators will be maintained for backup, ensuring uninterrupted power and grid stability, especially during periods of high, tourism-driven demand.
- Capacity and Impact: With a planned capacity of 30–40 MW, the project is set to achieve a renewable energy penetration of up to 70% on the island by 2030. This is projected to cut annual CO2 emissions by an estimated 20,000 to 30,000 tons.
- Investment and Timeline: TotalEnergies is making a substantial investment, reported to be between €50 and €100 million. Construction commenced in the first quarter of 2025, with the microgrid expected to be fully operational by late 2026 or early 2027. The Cape Verde government, through the state utility Electra, is facilitating the project by providing land, permits, and crucial regulatory support.
A Blueprint for the Future: The Cape Verde microgrid
The Sal Island microgrid is more than just an infrastructure project; it is a powerful showcase of what is possible for island nations worldwide. According to reports from the International Renewable Energy Agency (IRENA), island microgrids serve as critical models for energy transition, and the Sal initiative is poised to become a leading case study.
By successfully integrating a high percentage of intermittent renewables like solar with advanced battery storage, Cape Verde and TotalEnergies are creating a replicable blueprint. The project addresses key challenges like grid stability and intermittency while building resilience against climate-related risks like hurricanes through robust design standards.
As developments continue, this partnership stands as a clear example of how public-private collaboration can accelerate the transition to sustainable energy, paving the way for a more secure and environmentally sound future for Cape Verde and other island nations.
