California’s energy agencies are taking a first stab at assessing possible pathways to the state’s ambitious goal of achieving 100% renewable and zero-carbon electricity by 2045, but concerns about system reliability — especially in light of the rolling blackouts — continue to plague regulators. The California Public Utilities Commission (CPUC), California Energy Commission (CEC) and California Air Resources Board (CARB) released a draft report on getting to a 2045 clean electricity portfolio, which indicated the goal is technically achievable. To learn more, read “California’s pathway to 100% clean electricity begins to take shape, but reliability concerns persist.”
- The report presents important initial insights into potential paths for the electric sector, Mary Nichols, CARB chair, said at the workshop, adding that “the initial work highlights the enormous challenge ahead, requiring a complete transformation in the type of electricity that Californians consume.”
- California’s carbon goals are part of legislation passed by the state in 2018, called Senate Bill 100, which calls for 100% of electric retail sales in the state to come from renewable energy and zero-carbon resources by the end of 2045.
- The bill also required the three energy agencies to create a report evaluating the policy and follow it up with updates at least every four years. The agencies intend to submit a final version of the initial report early next year.
- Based on this analysis, the report concludes that achieving the 100% clean electricity goal is technically achievable, and could cost around 6% more than the baseline 60% Renewable Portfolio Standard (RPS) future by 2045, although that could change if renewables continue to decline in cost at a faster rate than anticipated by the models.
Path to 100% Perspective
A place where the transition to renewables has progressed quite far already is California. The lessons learned along the way have been plentiful, but powerful nonetheless. The record-breaking heat wave that swept across the western part of the country and caused a series of blackouts in the Golden State, offered additional modelling opportunities to demonstrate the most effective mix of energy to accommodate any extreme weather situation during the transition, and to meet clean power mandates. The big challenge facing California and the rest of the world is how to integrate renewables into the grid while building security of supply and a sustainable power system with an affordable plan for everyone involved.
