In combination, an interlocking electrical network, a steam generating power plant connected to the interlocking electrical network, and a system for superconducting magnetic energy accumulation disposed independently of and remotely from said power plant at a junction of said electrical network, comprising:
- a steam turbine in said steam generating power plant;
- a steam bleeder line connected to said steam turbine;
- and
- a control unit for furnishing electrical power into the electrical network directly from said superconducting magnetic accumulator to level a power deficit lasting on the order of several seconds, and simultaneously, said control unit increasing steam available to said steam turbine.
