California has been a leader in renewable energy goals in the United States, with an emphasis on clean energy sources such as wind, solar, and hydroelectric power. However, the state has also faced challenges with skyrocketing electricity prices and an unreliable electric grid. In response, California has proposed a controversial plan to charge households for electricity based on their income, which has led to accusations of socialism and government overreach. This plan aims to make energy more affordable for low-income families, but it remains to be seen if it will be successful in addressing the state's energy challenges.

What You'll Learn
California's electricity market is dysfunctional
California's electricity market has been dysfunctional for three decades and could end up being run by the state government. The state has been attempting to balance two conflicting goals: limiting greenhouse gas emissions from electricity production and maintaining electric system reliability.
In the late 1990s, California enacted a complex program of industry restructuring and reforms to create competitive wholesale and retail markets for electricity. This was driven primarily by pressure from business customers who wanted to reduce the state's retail electricity prices, which were among the highest in the United States. The California market has some unique features, including the fact that utilities own and operate their own generating plants but also purchase significant amounts of power in the wholesale market from other Western states, Canada, and Mexico.
The Federal Energy Regulatory Commission (FERC) regulates wholesale power prices, while the California Public Utilities Commission (CPUC) regulates retail prices. In 1998, California's restructured electricity market began to experience problems due to market design issues, regulatory failures, and bad luck. Wholesale electricity prices rose dramatically, increasing by 500% between 1999 and 2000. This was driven by several factors, including rising natural gas prices, high electricity demand due to hot weather and strong economic growth, increased air emissions permit prices, and supplier market manipulation.
Despite these high wholesale prices, retail prices remained capped by state regulation, resulting in significant losses for utilities. Additionally, the utilities were required to divest most of their generating capacity and were not allowed to hedge their default service obligations by entering into forward contracts. As a result, California's new wholesale spot market institutions struggled to meet the high retail demand.
In recent years, California has been transitioning to cleaner energy sources and adding significant clean energy capacity to its grid. However, critics argue that the state's reliance on wind and solar generation has made its electric grid increasingly unreliable and led to skyrocketing prices. California has shut down many natural gas power plants since 2013 and imports electricity from neighbouring states, which may not be a sustainable strategy in the long term.
To address high electricity prices, three major utility companies in California have proposed charging customers based on their household income. This plan would include a fixed infrastructure charge and an electricity use charge. While this could reduce costs for low-income families, it represents a significant departure from traditional utility rate-making principles, which emphasize that customer expenses should be based on the cost of providing the service.

The state is aiming for ambitious clean energy goals
California has set ambitious clean energy goals, aiming for 100% zero-carbon electricity sales and net-zero greenhouse gas emissions by 2045. The state has made significant progress, adding more than 25,000 megawatts (MW) of new clean energy resources to its grid over the past five years, with a record increase of nearly 7,000 MW in 2024 alone. This expansion includes the development of large-scale battery storage systems, with a sevenfold increase in capacity over the past four years.
To achieve its ambitious goals, California has implemented a range of measures. The state has passed critical carbon capture legislation, SB 905, to expand its clean energy solutions. It has also set interim goals of 90% zero-carbon electricity sales by 2035 and 95% by 2040. More than 20,000 MW of clean energy projects are already under contract and in development to serve California customers by 2030. The state is also exploring public ownership of utilities, such as PG&E, to protect residents from unaffordable rates.
However, California faces challenges in its transition to clean energy. The state has shut down many natural gas power plants, increasing its reliance on weather-dependent wind and solar generation, which has led to skyrocketing electricity prices. Connecting new renewable projects to the grid has also been difficult due to a backlogged approval process. Additionally, California's goal of 100% clean energy will require a significant expansion of infrastructure, with estimates suggesting 180 solar farm projects similar to the Topaz Solar Farm may be needed.
Despite these challenges, California is a leader in climate and clean energy policy, and its progress is notable. The state has reduced greenhouse gas emissions by 20% since 2000 while achieving a 78% increase in GDP. It has also run on 100% clean electricity for the equivalent of 51 days in a year, with the grid running on clean energy for some period three out of every five days. California's rapid expansion of clean energy capacity is the result of procurement orders from the California Public Utilities Commission (CPUC), which aims to bolster grid reliability and meet Renewables Portfolio Standard (RPS) requirements.

California's electricity rates are the highest in the nation
California's electricity rates are among the highest in the nation. On average, residential electricity rates in California are close to double the national average. The rates have been increasing rapidly in recent years, growing faster than inflation and outpacing growth in other states. These trends are expected to continue.
The high electricity rates in California are driven by several factors, including the high rates charged by the state's three large investor-owned utilities (IOUs): PG&E, SCE, and SDG&E. From 2019 to 2023, the average rates charged by these IOUs increased between 48% and 67%, while the overall growth in prices was only about 18%. Additionally, California has ambitious greenhouse gas (GHG) reduction programs and policies, and significant and increasing wildfire-related costs, which contribute to the high electricity rates.
In an attempt to address the high electricity rates, three major utility companies in California have proposed charging their customers based on their household income. This plan would include a fixed infrastructure charge, tiered by customer income level, and an electricity usage charge based on consumption. While this plan could reduce costs for low-income families, it may also result in higher charges for higher-earning families.
California has also been adding clean energy capacity to its grid at an unprecedented pace. In 2024, the state added approximately 7,000 megawatts (MW) of new clean energy, marking the largest single-year increase in state history. California is committed to bolstering grid reliability and advancing its clean energy targets, which may help improve the state's electricity rates in the future.
Despite the high electricity rates, California's electric grid has faced reliability issues. The state's reliance on weather-dependent wind and solar generation, coupled with the shutdown of natural gas power plants, has led to an unreliable electric supply. As a result, California has had to import electricity from neighboring states, which may not be a sustainable solution in the long term.

The state has shut down too many natural gas power plants
California has been criticized for shutting down too many natural gas power plants since 2013. This has resulted in an overreliance on weather-dependent wind and solar energy generation, as well as electricity imports from neighboring states. The state's strategy has been described as doomed to fail, as other states are also shutting down their coal and natural gas plants, reducing the availability of alternative power sources for California.
California's approach to energy has been characterized as a form of "energy socialism," with proposals to charge households based on their income rather than a flat rate. This plan aims to make energy more affordable for low-income families while increasing charges for higher-earning households. However, critics argue that this strategy will lead to skyrocketing electricity prices, particularly affecting low-income families.
California's commitment to unreliable wind and solar technologies is seen as a contributing factor to increasing electricity costs. The state's efforts to transition to clean energy and improve air quality are recognized, but the dual goals of reducing greenhouse gas emissions and maintaining electric system reliability are challenging to achieve simultaneously.
The state's actions, such as the potential public takeover of PG&E, have fueled concerns about government intervention in the free market and a move toward socialism. California's energy market has been described as dysfunctional, with the government's role raising questions about labor productivity and the direction of production.
While California has made significant progress in adding clean energy capacity to its grid, the shutdown of natural gas power plants has sparked debates about the reliability and affordability of its energy sources. The state's strategy of relying on renewable energy sources and imports from neighboring states has faced criticism, with concerns about potential power shortages and increasing electricity prices.

California's energy grid is increasingly unreliable
California's energy grid is facing a number of challenges that are testing its reliability. The state has ambitious clean energy goals, and while it has made significant progress in recent years, there are concerns about the grid's ability to keep up with demand.
One of the main issues is the intermittency of renewable energy sources like wind and solar power, which are dependent on weather conditions and the time of day. This makes it difficult for grid operators to balance supply and demand, and can lead to shortages and rolling blackouts during periods of high demand. California's decision to shut down natural gas power plants and rely more on these renewable sources has made its energy grid increasingly unreliable, with the state even importing electricity from neighbouring states. However, as these states are also shutting down their own reliable coal and natural gas plants, they may not be able to continue supplying California in the future.
Another challenge is the need for better technology to store large amounts of electricity and discharge it over longer periods, especially during weather events that affect wind and solar output. Most large-scale batteries currently use lithium-ion technology, but these can only discharge for about four hours at most. California is investing in battery storage, with a 1,944% increase since the Newsom Administration, but more needs to be done to ensure the grid can handle extreme weather events, which are becoming more frequent due to climate change.
The state is also facing challenges due to its ambitious climate goals, which some argue are not being met quickly enough. For example, there is debate over the Diablo Canyon nuclear plant, with some calling for its closure and others arguing it is needed to keep the lights on. There are also concerns that not enough is being done to invest in renewable energy and batteries to move off fossil fuels, with calls for investment akin to the Marshall Plan.
Despite these challenges, California has made significant progress in adding clean energy capacity to its grid. In 2024, the state added approximately 7,000 megawatts of new clean energy, the largest single-year increase in its history. The state has also run on 100% clean electricity for three out of every five days, demonstrating that its clean energy future is compatible with reliability. California's energy leaders believe the grid is stronger and more resilient than in previous years, and are optimistic about meeting demand in the summer of 2025.

Frequently asked questions
California has been adding more clean energy capacity to its grid faster than ever before. In 2024, California added approximately 7,000 megawatts of new clean energy, marking the largest single-year increase in state history.
Before the current push for renewable energy, California relied heavily on natural gas power plants, which provided about a third of the state's electricity demand in 2019. The state also imported a significant amount of electricity from neighbouring states, particularly wind and hydroelectric power from the Pacific Northwest.
Critics argue that California's focus on renewable energy sources has led to skyrocketing electricity prices and an unreliable electricity grid. There are concerns that the state is overly reliant on weather-dependent wind and solar generation, and that the proposed income-based utility billing punishes productive, successful individuals by having them subsidise rates for lower-income customers.
