Energy production that correlates (in many parts of the world) with peak load from air conditioning. This saves fuel and wear and tear on expensive peaker plants.<p>The generation is distributed, which saves on distribution and transmission costs.<p>Planning for expansion is also based on peak loads, which as noted above, solar reduces saving yet more money.<p>There&#x27;s some worked examples for Minesota here:<p><a href="https:&#x2F;&#x2F;www.nrel.gov&#x2F;tech_deployment&#x2F;state_local_governments&#x2F;blog&#x2F;vos-series_minnesota" rel="nofollow">https:&#x2F;&#x2F;www.nrel.gov&#x2F;tech_deployment&#x2F;state_local_governments...</a>
