Abstract

Method, in particular a computer-implemented method, for operating an electrically operated process room (102, 202) of an industrial system (100, 200), comprising the steps: - Setting (402, 404) a process variable (104, 204) within the process space (102, 202), wherein the setting is done by providing electrical energy from a power grid (116, 216), - wherein the process size (104, 204) is set within a process size tolerance range (305) with at least one process size threshold (300) within the process space (102, 202), - Receiving (400) a power grid information (110, 210) representing an energy availability in the power grid (116, 216), - wherein the use of electrical energy to adjust the process variable (104, 204) in the process space (102, 202) is increased when the energy availability in the power grid (116, 216) is high, so that a buffer (312, 314) is built up between the adjusted process variable (104, 204) and the process variable threshold (300), and - wherein the use of electrical energy to adjust the process variable (104, 204) in the process space (102, 202) is reduced when the energy availability in the power grid (116, 216) is low, so that the process variable (104, 204) is adjusted up to a maximum of the process variable threshold (300), - characterized in that the industrial system (100, 200) is a system for battery cell manufacturing, - the process room (102, 202) is a cleanroom and / or dry room for carrying out battery cell manufacturing processes, and - the process parameter (104, 204) is a humidity level or a dew point within the cleanroom and / or dryroom.
