Energy Storage Solutions
Battery energy storage systems (BESS) have become a critical part of the electricity system, especially when it comes to the integration of renewable energy, and providing grid stability, among other services. Application possibilities are expanding as competition increases. The value of energy storage is especially relevant when comparing it to alternative investments in the additional infrastructure of distribution system operators (DSOs) and transmission system operators (TSOs).
Enertis Applus+ has been in the global energy storage business since 2018, with an accumulated experience of 30 GWh of installed power.
By combining engineering services for battery materials selection with guidance on manufacturing steps/risks, regulatory impacts, growth strategies, and connections to a network of bankable storage providers and integrators, we assure long-term performance predictability, protect client profits, and lower overall client risk.
As part of our services, with our SIMUBATT+ Enertis software, we provide comprehensive technical and economic feasibility studies of the hybridization of renewable technologies with BESS applications, performing detailed simulations of various possible combinations to support our clients’ decision-making process.
