Senegal is taking another step in its energy transition. Senelec has launched a battery energy storage plant project, linked to the Diass solar power plant, representing an investment of over 23 billion CFA francs, or approximately 36 million euros. This infrastructure, presented as a first in the country and the sub-region, aims to improve the stability of the national electricity grid while strengthening the integration of renewable energies.
A Strategic Project for the Grid
The core of the project is a battery energy storage system, or BESS, capable of storing the electricity produced by the solar power plant before redistributing it to the grid as needed. The objective is clear: to smooth out production variations linked to sunshine and guarantee a more regular supply, particularly during peak hours.
Specifically, the infrastructure comprises 30 battery containers and 360 inverter units. It should allow for the storage and release of more than 20,000 MWh of energy per year, representing a significant contribution to ensuring the continuity of electricity service.
A solution to solar intermittency
One of the main challenges of renewable energies remains their intermittency. A solar power plant produces more during the day, while demand can remain high in the evening or during peak consumption periods. Storage allows precisely for correcting this mismatch between production and consumption.
For Senegal, this solution is particularly important in a context where electricity demand continues to grow. By utilizing solar electricity beyond just daylight hours, Senelec is equipping itself with a more flexible and modern management tool.
Support from European partners
The project benefits from international co-financing, with Germany through KfW and France through the French Development Agency. This support is a continuation of the Smart Grid program, launched in 2018 to modernize Senegal’s distribution network and facilitate the integration of renewable energy.
This cooperation demonstrates that Senegal’s energy transition is attracting partners committed to sustainable infrastructure. It also confirms the electricity sector’s position as a priority for public policy and donors.
Less hydrocarbons, more sovereignty
Beyond the technical stability of the network, the project has a significant economic dimension: reducing Senegal’s dependence on imported hydrocarbons. By improving solar energy storage, the country can limit its reliance on thermal power plants when renewable energy production declines.
In a context of high energy price volatility, this development can help secure the costs of the electricity system and strengthen the country’s energy sovereignty. For the authorities and for Senelec, this is therefore an industrial, financial, and strategic investment.
A strong signal for the future
The Diass project is not limited to simple technical infrastructure. This marks Senegal’s entry into a new energy paradigm, where renewable energy production must be accompanied by storage solutions capable of maximizing its efficiency.
If its implementation is successful, this power plant could serve as a benchmark for other similar projects in the country and the sub-region. Above all, it illustrates a long-term ambition: to build a more reliable, cleaner, and better-adapted electricity system to meet the needs of a growing economy.
