The California 2030 Low Carbon Grid Study (LCGS) explores how the electric sector can cost-effectively support deep reductions in greenhouse gas (GHG) emissions. According to Phase I modeling results, the California grid can reduce emissions by more than 50% below 2012 levels by the year 2030 with minimal rate impact, minimal curtailment to renewables, and without compromising reliability. These findings are significant because they illustrate an affordable, reliable, and practical trajectory toward meeting California’s ambitious 2050 GHG emissions goals.

The LCGS is unique in its focus on emissions reduction, and in its use of a diverse set of resources and portfolio-balancing measures aimed at achieving a cost-sensitive, low-carbon grid without major disruption to transmission flows or trading patterns. The final report will remain neutral on specific policy recommendations, as the LCGS is primarily a technical informational tool, broadly applicable to a variety of energy policy and planning decisions.
