en.Wedoany.com Reported - Mauritius has recently launched a tender for solar and battery energy storage projects totaling 220 MW, published through the International Solar Alliance Small Island Developing States e-Marketplace platform. The projects are open to independent developers and international financing institutions, aiming to add a batch of dispatchable clean power to Mauritius's electricity system and reduce the island nation's reliance on imported fossil fuels.

This tender round includes 13 solar-plus-storage projects, specifically comprising 10 projects of 10 MW each and 3 projects of 40 MW each, all requiring integration with battery energy storage systems. The projects were initially launched in April, with the bid submission window expected to close in mid-July 2026; during a recent Small Island Developing States dialogue event held in Bali, Indonesia, these projects were highlighted as representative cases on the International Solar Alliance e-Marketplace platform. The platform, promoted by the International Solar Alliance, provides unified publication, project preparation, developer matching, financing institution access, and tender support services for solar and energy storage projects in Small Island Developing States. For island power systems like Mauritius, individual project scales are often insufficient to attract enough international developers and long-term capital. The e-Marketplace centralizes government-endorsed projects, helping to enhance transparency, expand the scope of competition, and advance project preparation, financiability assessment, and procurement processes within a more standardized framework.

Mauritius's power system has long been affected by fuel imports, international oil price fluctuations, limited land resources on the island, and electricity demand from tourism. Solar resources are viable for development, but without energy storage, there remains a scheduling mismatch between high daytime generation periods and nighttime loads. The solar-plus-storage project portfolio can absorb solar power during the day and release electricity in the evening and at night, alleviating peak demand pressure and increasing the actual usable proportion of renewable energy in the island's grid. The country has previously proposed adding approximately 405 MW of renewable energy and storage capacity over the next three years, and this 220 MW tender will form a more scaled group of projects within that plan, driving demand for supporting components such as photovoltaic modules, inverters, battery systems, energy management, step-up connections, fire safety, and long-term operation and maintenance.

Subsequent project milestones focus on bid submission deadlines, developer selection, power purchase agreement arrangements, financing implementation, and grid connection plan confirmation. If the tender is successfully completed, Mauritius will gain a series of distributed solar-plus-storage power stations, providing a more stable increment of clean energy for its power system. If this platform model proves effective in Mauritius, it may also be replicated by more small island nations in the Pacific, Indian Ocean, and Caribbean to address issues such as fragmented small-market projects, high financing costs, and insufficient international developer participation.
