18 Overview: Energy Storage
lEnergy is stored to use it at a different time than when
it was generated
lThe process of converting the
energy to storable form means that some energy is lost due to
inefficiency
lAdditional
energy is lost when the energy is released or recovered due to a
second inefficiency
lIdeally, storage is avoided to have a more efficient process
lTime-of-day metering is
likely in the future as metering becomes electronic and
inexpensive (like a thermostat)
lShifting the energy from usage
peaks to low-use times helps the utility, and customers would be
rewarded by lower charges
