Claim 2:
3. The method according to claim 1, further comprising:
defining a decreasing function TC(Pel)=funct (Pel), in which TC(Pel) is dependent on a varying price Pel for a unit of electricity, and TC(Pel) is decreasing within the thermocline control interval for increasing Pel within an interval [Pmin; Pmax] of electricity prices, wherein TC(Pmin)=Tmin+0.65 ΔT and TC(Pmax)=Tmin+0.25 ΔT;
receiving an actual price Pact for a unit of electricity valid for a planned time of charging;
determining TC(Pact); and
supplying electrical energy to the TES system only until the Tend reaches the TC(Pact).
