Chile has taken a significant step toward strengthening its renewable energy capacity. 240 Tesla Megapack energy storage systems have been delivered to the Colbun Solar Cell project, which will be built in the Arica and Parinacota regions of the country.

Tesla delivers 912 MWh of Megapacks

This delivery powers one of Chile’s largest energy storage projects. Each Megapack weighing 38.1 tons was transported from the port to the construction site by special tractors. One Megapack battery can store over 3.9 MWh of energy and can power approximately 3,600 homes in one hour.

The project’s total capacity is 228 MW of power and 912 MWh of storage. This means the system can provide continuous power for four hours. The installed system is capable of meeting the energy needs of an average of 55,480 homes.

According to Colbun, the total investment cost of the Solar Cell project is $260 million. The project will include the construction of infrastructure, a 220 kV transmission line, and support buildings across a 10-hectare site. Following the installation and testing of the Megapacks and other components, the project is expected to become operational in mid-2026.

The system will enable the efficient storage of electricity generated from the country’s renewable energy sources. This will increase the stability of the electricity grid and ensure energy continuity, particularly during nighttime hours when solar energy production is not available.

Such large-scale storage solutions offer a critical solution to the problem of discontinuity, one of the biggest obstacles to the widespread adoption of renewable energy.
