This means of energy storage captures excess electric power from renewable sources, or from the grid, with an electric motor / generator and stores that energy with a mechanically connected energy storage spring. When the stored electric power is required, energy is released from the energy storage spring and transferred back to the same mechanically connected electric motor / generator that connects back to the grid or to another consumer.

Advantages over Pumped Hydro Power

• Energy storage springs are deployable everywhere.
• They don't require water.
• Energy storage springs also scale more easily to meet demand.

Advantages over Batteries

• Springs / coils, fabricated from spring steel, are affordable and completely recyclable.
• Spent batteries must be disposed of properly and new batteries require additional resources.
• Energy storage springs never leak their contents.

Advantages over Rotation

• Energy storage springs don't require energy to levitate / maintain its means of energy storage.
• Reduces, or eliminates entirely, the need for rotational storage at power plants.
• Traditional power plants can store excess power, rather than shutting down.
