Transmission and distribution networks regulation through dedicated cableway plants

The interest on storage systems connected to transmission and distribution grids to supply ancillary services is growing fast. The paper investigates the opportunities achievable through a dedicated Cableway Storage System in supplying ancillary services to the grid, compared with traditional storage plants based on pumped hydro or modular construction batteries approaches. The basic idea, its advantages and a realistic case study are presented to qualitative define the proposed technology, its requirements and a first preliminary design.
