From Isemaren Energy Solutions we give support in the projects in which batteries are key elements and facilitators of integration of renewable energies in the networks and optimizing the management of the demand.

We dimension the storage systems with optimal batteries in each case considering the most important functional characteristics of the batteries such as the combination of power and capacity, response time, efficiency and costs.

We advise you in any of the phases of a project:


And in any of the financial operations: purchase-sale, financing, refinancing, bond issue, etc.

We offer services related to energy storage, sustainability and climate change.

In addition, we specialise in portfolio generation, standardisation and stabilisation.

We assess and value technically and economically the risks of the project.
