California's energy problems are escalating as demand from the state's tech industry outstrips available resources.

Millions of residents are at risk of outages, and in early 2001, the state endured a series of Stage 3 alerts, which often lead to widespread blackouts.
Scenes of power outages in California have become a regular feature on the news, as blackouts disrupt daily life—causing traffic jams from non-functional lights and forcing schools and businesses to close. This crisis, which has been ongoing for months, has been developing for years.
With the hottest months still ahead, California's power troubles are far from over. The state anticipates rolling blackouts until utilities can either boost supply or purchase additional power from neighboring regions. This edition of Mytour explores one of the worst energy crises in U.S. history, the factors behind it, and its potential to spread to other states.
Understanding the Origins of the Crisis
As you may expect, a lot of blame is being cast around in California regarding who is at fault for the recent energy shortage. However, this crisis did not appear overnight; it's the result of issues that have been developing for years. Below are some key factors that have contributed to the current energy situation:
- California Utility Deregulation - A major factor being blamed is the deregulation plan signed into law by former Governor Pete Wilson in 1996. The intent was to open up the state's electricity industry to competition. However, five years later, many see this deregulation as a key cause of the energy issues California faces today. When deregulation took place, California's major utilities sold most of their power plants to a small group of electricity wholesalers. The issue here is that deregulation gave power suppliers little incentive to increase their capacity to meet California's growing electricity demand. Governor Davis has suggested that suppliers may even be withholding supply to drive up prices, although they deny such claims.
- Increasing Power Demand - Over the past five years, demand for electricity in California has risen by 6 percent annually, according to Pacific Gas and Electric, one of the state's largest utilities. A significant portion of this increased demand comes from the many tech and internet companies based in cities like San Jose and San Francisco. A 1998 study indicated that the Internet accounts for 8 percent of total U.S. electricity consumption, though some critics argue this figure is exaggerated.
- Frozen Consumer Prices - As demand for electricity has risen, unregulated wholesale energy prices have skyrocketed. Yet, the rates charged to consumers remain frozen. This situation leaves utilities in a difficult position: they must buy electricity at higher deregulated prices but are limited in how much they can charge customers. As a result, two of California's major utilities—PG&E and SoCal Edison—are facing mounting debt. Both have warned that they may need to file for bankruptcy if the situation doesn't improve. On January 19, Governor Davis took action by approving $400 million in state funds to purchase power and help struggling utilities.
- Lack of New Power Plants - California has not built significant new power plants in the past decade. Although four new plants are under construction, and another one has been approved, none of these plants will be operational in time to address California's power needs during the peak consumption months of the upcoming summer. Governor Davis has stated that these plants won’t be ready for at least two more years.
- Out-of-State Power Suppliers Cutting Back - California relies on out-of-state companies for about 25 percent of its electricity needs, according to the California Energy Commission. These companies have become increasingly unwilling to supply power to California due to concerns about the state’s utilities’ ability to pay for it. To address this, on January 11, U.S. Energy Secretary Bill Richardson issued an emergency order requiring these companies to continue supplying power to the state.
- Reduced Hydroelectric Power Due to Weather - California also depends on power from the Pacific Northwest, where hydroelectric power generation is key. However, a lack of snow and rainfall in the region has reduced the available electricity from hydroelectric plants, further limiting the amount of power California can access.
California officials face tough decisions in the coming weeks and months. In the meantime, they are trying to address the situation with rolling blackouts across the state. The next section will explain how these rolling blackouts function.
How Rolling Blackouts Work
When California experiences a power shortage, the California Independent System Operator (Cal-ISO), responsible for managing the state's power grid, informs local utilities that they must reduce the load on the statewide power system. The utilities then decide how to implement the load reduction, usually by initiating blackouts in specific areas for a set number of hours.
The California ISO is an independent organization tasked with overseeing the transmission of electricity through the state's long-distance, high-voltage power lines. It also works to ensure a reliable electricity supply. Contrary to some reports, the Cal-ISO does not have the authority to order blackouts. Only local electric suppliers can take that step.
Rolling blackouts are a last-resort measure, used to avoid a total failure of the state's electrical grid. They are triggered when the state's power reserves drop below 1.5 percent.
Here’s how California’s rolling blackouts operate:
- The state is divided into large sections by the utility companies. For instance, PG&E organizes their service area into several blocks.
- Once the energy crisis escalates to a Stage 3 emergency, the California ISO alerts local electric suppliers that they need to reduce the overall load on the state’s system. These local suppliers then begin implementing rotating power outages.
- The outages follow a set order, starting with block number one. If the energy crisis persists, the next block, number two, will be affected. PG&E customers can locate their block number on their service bill.
- Critical services like hospitals, police stations, fire departments, and some nearby residents are exempt from the rolling blackouts.
Not Just a California Problem
California, which makes up roughly 12% of the total U.S. population with over 33 million residents, is home to a significant number of high-tech firms. These companies consume far more energy than traditional industries. Consequently, a tremendous amount of power needs to be generated to satisfy the state's growing energy demands.
The effects of California's energy crisis are already being felt across the western United States. As electricity prices in California have surged (tripling since November 1999), neighboring states have seen their electricity costs rise as well, since California imports power from them. The state’s increased demand for electricity has reduced the amount available for export, further exacerbating the crisis. Additionally, the rapid growth of cities like Las Vegas and Phoenix has played a role in escalating the situation.
If you're living on the eastern side of the U.S., you might think you're insulated from the West Coast's current energy struggles. But if the situation continues to deteriorate, what we’re seeing in California could be just the beginning of a nationwide energy shortage.
At least 25 states have started to deregulate their electric utilities, which means that eventually, many could face similar challenges as California is currently experiencing. Two states, Nevada and Arkansas, have paused or delayed their deregulation efforts for now, opting to observe how California handles the issue and the consequences that follow.
