Hybrid energy systems and energy storage

Hybrid energy systems and energy storage 

Decentralised electrification
There are still many isolated regions around the world that cannot be supplied by existing grids. Giving people in these areas access to electricity requires a thorough understanding of the needs and locally available resources. Having gained experience in this approach through its rural development work, Artelia proposes a wide array of solutions for setting up autonomous power plants based on renewable energy or hybrid systems and for installing distribution micro-grids.

Energy storage
New - i.e. local and renewable - energy sources are gaining strong momentum. To achieve this revolution, a solution must be found to the problem of storing the electricity generated from renewables, which are by essence intermittent, so that they can respond at all times to demand from users, which also fluctuates. 

The rapid increase in the share of renewables in the electricity being generated is hence a challenge for grid operators and a field in which our teams are heavily involved. The intermittent nature of solar and wind energy and their diverse geographical locations are raising new technical and organisational issues that need to be addressed. 

Artelia has developed resources for modelling storage solutions and a range of services to facilitate the integration of renewable energy sources into power grids. In parallel our teams are developing a technical and economic design software application (Opti’Stor) for hybrid power plants.


Liberia chose to focus on renewable energy in its development plan for the Saint Paul River basin to strengthen its national electricity supply and contribute to the interconnected CLSG (Côte d’Ivoire-Liberia-Sierra Leone-Guinea) network.


The client is an Independent Power Producer operating its own electrical plants in Madagascar: these thermal plants are connected to two local micro-grids (Tulear and Diego), or to the main network (Antananarivo).
