Peak power spreading
A system including a battery system to provide additional power during peak operating conditions is described. The system may avoid or reduce the need for extensive infrastructure associated with a power delivery system capable of providing peak power, but may instead, rely on infrastructure that need only provide power needed on an average basis.

10. A water and light display that provides a performance, wherein the performance has a power consumption threshold that is exceeded at a predetermined time during the performance, the display, comprising:
at least one water delivery device that consumes power;
at least one lighting element that consumes power;
a main source of power;
an alternative source of power;
a mechanism that adds power from the alternative source of power to power from the main source of power to form combined power when the power consumed by the at least one water delivery device and the at least one lighting element exceeds the power consumption threshold, and that delivers the combined power to the at least one water delivery device and the at least one lighting element; and
a controller that controls the mechanism to form combined power and to deliver combined power at the predetermined time.
11. The water and light display of claim 10 , wherein the alternative source of power is an energy storage device.
12. The water and light display of claim 11 , wherein the energy storage device is a battery or a capacitor.
13. The water and light display of claim 10 , wherein the controller controls the mechanism to deliver power from the main source of power to the alternative source of power to charge the alternative source of power at other than the predetermined time when the power consumed by the at least one water delivery device and the at least one lighting element is below the power consumption threshold.
14. The water and light display of claim 10 , wherein the main power source has a variable cost associated with it delivering power, and the charging occurs during a time of day when the cost is low.
15. The water and light display of claim 10 , comprising two or more alternative sources of power; wherein each of the two or more alternative sources of power are located in close proximity to at least one water delivery device and at least one lighting element.
16. A water and light display that provides a performance, wherein the performance has a power consumption threshold and the performance has a predetermined choreography involving different levels of power consumption during the performance, including a predetermined time when the power consumption threshold is exceeded, the display, comprising:
at least one water delivery device that consumes power;
at least one lighting element that consumes power;
a main source of power;
an alternative source of power that is a battery or a capacitor; and
a mechanism that adds power from the alternative source of power to power from the main source of power to form combined power when the power consumed by the at least one water delivery device and the at least one lighting element exceeds the power consumption threshold based on the predetermined choreography;
a controller that directs the mechanism to form combined power based on the choreography at the predetermined time when the power consumption threshold is exceeded.
