7.2.5—Intermittent energy production

Level
HL

Store the Surplus, Release the Shortfall

Storage shifts surplus energy to a later shortfall; it does not create energy.

Intermittent output must be charged when supply exceeds demand and discharged when demand exceeds output, with losses.

A battery charges from midday solar and discharges during the evening peak.

What job does storage perform? timing and balancing, not generation.

Storage is not a new energy source.
