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.
