Chemical stability when used in the technical sense in chemistry, means thermodynamic stability of a chemical system. Thermodynamic stability occurs when a system is in its lowest energy state, or chemical equilibrium with its environment.This may be a dynamic equilibrium, where individual atoms or molecules change form, but their overall number in a particular form is conserved.This type of chemical thermodynamic equilibrium will persist indefinitely unless the system is changed.his may be a dynamic equilibrium, where individual atoms or molecules change form, but their overall number in a particular form is conserved.

Rate base (utility) Rate base is the value of property on which a public utility is permitted to earn a specified rate of return, in accordance with rules set by a regulatory agency. In general, the rate base consists of the value of property as used by the utility in providing service.
Electric demand refers to the maximum amount of electrical energy that is being consumed at a given time. It is measured in both kilowatts and kilovolt amperes, depending on the rate tariff.lectrical Utilities typically charge commercial and industrial customers for both consumption (kWh) and Demand (kWd or kVa). As everyone knows, electric rates vary by state and utility company. Utilities have different tariffs for different types of customers (users).
