For example, the amount of sunlight that can be captured by solar photovoltaic panels and converted to electricity depends on the weather (sunny or cloudy) and the angle of incoming sunlight (which depends on the season and time of day). Utilities and grid operators need to ensure that enough power will be generated to meet demand when it is high.

Quarry supplies iron ore for CalPortland's cement plants and to other markets. The local source of iron ore reduces the need to import iron ore from more distant sources, thus reducing environmental impacts and transportation costs. The Baxter Quarry (project site, quarry) has been explored and mined historically since 1938,
