In this paper cold and thermal storage options via wind energy surplus are examined aiming to enable higher wind integration. A case study in Greece with an installed wind farm (WF) was investigated reviewing the possibilities for higher renewables integration using thermostatically controlled loads (TCLs), analysing thermal and cold storage possibilities according to the needs of the local municipalities. The basic aim is to describe the idea of an aggregated system with a number of residential freezers, in order the wind power to be stored in the residential cold stores aiming at maximizing the benefit to the grid, utility or cold store owner avoiding at the same time wind curtailment. In addition, for thermal storage, by calculating thermal losses of the building, ventilation losses and adding up internal thermal gains of the building the space heating needs can be calculated.
