  • ALTEO group, Hungary
    Electric grids are evolving rapidly, disrupted by deregulation, distributed energy resources, renewable portfolio standards, and smart grid technologies. Energy storage is uniquely positioned at the heart of this transition. One of the lesser known, though quite significant, energy technologies focuses on optimising the current thermal energy generation infrastructure. Energy storage systems (ESS) have emerged as a viable upgrade to optimise generation performance for both renewable and traditional power sources and to help energy providers increase their revenue streams.
