What You'll Learn
San Diego's unique service area
San Diego's electric service area is unique in California. While other investor-owned utilities like Southern California Edison and Pacific Gas and Electric serve large swaths of the state, San Diego's utility company, San Diego Gas & Electric (SDG&E), caters only to San Diego County. This means that SDG&E has a smaller customer base over which to spread its costs.
SDG&E's customer base is also unique in that it has the highest solar adoption rate in California. Many residents with rooftop solar installations pay less towards maintaining the energy grid, further reducing the pool of funds from which the utility company recoups costs.
Additionally, SDG&E has been investing in infrastructure upgrades to meet increasing demands and protect against wildfires, which have contributed to the rising electricity prices in San Diego. These costs are passed on to the customers, and as a result, electricity prices in San Diego have skyrocketed in recent years.
The delivery charges on SDG&E bills are also impacted by the unique service area. These charges include the costs of operating energy systems, construction, modernisation, and upkeep of equipment needed to deliver electricity. The specific rates may vary depending on a customer's usage and location within the service area.
The unique dynamics of San Diego's electric service area, including its isolated nature, high solar adoption rate, and infrastructure costs, contribute to the high electricity prices experienced by residents.

Rooftop solar adoption
San Diego has some of the most expensive electricity prices in the US. There are several reasons for this, including the fact that the city's electric service area only covers San Diego County, meaning that the costs are spread across a smaller population. Additionally, San Diego Gas & Electric (SDG&E), the main utility company in the region, has been spending more on building and protecting infrastructure while selling less energy.
One of the key factors contributing to the high cost of electricity in San Diego is the city's high adoption rate of rooftop solar. California's solar adoption is highest in San Diego County, and this has had a significant impact on the energy grid and the utilities' ability to recoup costs. Rooftop solar adoption has led to a decrease in revenue for utility companies like SDG&E, as those with rooftop solar pay less towards maintaining the energy grid. This has sparked an ongoing political debate in California's renewable energy sector about how to account for rooftop solar adoption fairly.
The debate surrounding rooftop solar adoption in San Diego centres around the question of cost distribution. On the one hand, rooftop solar is a clean and renewable energy source that can help reduce the city's carbon footprint and combat climate change. Proponents of rooftop solar argue that it is a necessary step towards a more sustainable future and that the cost of transitioning to renewable energy sources should not be borne solely by those who adopt it early.
On the other hand, critics argue that the high cost of electricity in San Diego is partly due to the reduced revenue from rooftop solar customers, who pay less towards maintaining the energy grid. SDG&E has claimed that rooftop solar customers contribute to higher prices for other customers, although this has not been conclusively proven. There is also a concern that SDG&E has blocked efforts to clarify the impact of rooftop solar adoption on electricity rates.
Despite the ongoing debate, rooftop solar adoption is likely to continue to grow in San Diego and California as a whole. The state has been encouraging the transition to renewable energy sources, and solar energy is particularly attractive in sunny areas like San Diego. As a result, residents may see their electric bills decrease as they rely less on grid electricity. However, the cost of electricity for those without rooftop solar may continue to rise to make up for the lost revenue.
Overall, the high cost of electricity in San Diego is a complex issue with several contributing factors, and rooftop solar adoption is a significant part of this discussion. As the city and state continue to promote renewable energy, the impact of rooftop solar on electricity rates will likely remain a key topic of conversation.

High construction and infrastructure costs
San Diego Gas & Electric (SDG&E) has invested heavily in protecting its infrastructure against wildfires since the 2007 fires that ravaged parts of San Diego and were blamed on SDG&E equipment. The company has spent billions to safeguard its poles and wires, and these costs are passed on to the consumer.
SDG&E is also facing reduced revenues due to the high adoption of rooftop solar in San Diego County. People who own rooftop solar pay less toward maintaining the energy grid, reducing the pool of funds from which utilities recoup costs. This has led to SDG&E selling less energy while spending more on building and protecting infrastructure to transport it.
Additionally, San Diego's electricity grid is relatively isolated, serving only San Diego County, while other investor-owned utilities in California serve larger areas. This smaller customer base means higher costs for SDG&E, which are again passed on to the ratepayers.
The costs of delivering electricity, or "delivery charges," can also vary depending on a customer's rate and electricity use. These charges cover the costs of operating energy systems, construction, modernization, and upkeep of equipment like pipes, wires, and substations. Delivery charges also include costs for customer service, service technicians, meters, and other operational equipment.
SDG&E is also allowed to collect a rate of return on everything it constructs, maintains, or upgrades, further contributing to higher costs for ratepayers.

Public purpose programs
San Diego's electricity rates are high due in part to "public purpose programs", which are initiatives designed to promote energy efficiency, support low-income communities, and encourage the adoption of renewable energy sources. These programs are funded by a small surcharge on customers' utility bills and are intended to You may want to see also San Diego's electricity prices have been relatively high for many years, but the rise has been rapid since 2020. According to a US BLS (Bureau of Labor Statistics) report, the electric rate rose by around 70% between May 2020 and December 2023. The average summer cost of energy jumped by 67% between January 1, 2018, and January 1, 2023. Electricity prices in San Diego have skyrocketed due to several factors, including extreme temperatures. The demand for electricity is typically higher during the summer and winter months, as residents require air conditioning or heating to maintain comfortable indoor temperatures. This increased demand results in higher electricity rates. The extreme temperatures in San Diego can also impact the cost of electricity by affecting the performance of power plants and transmission infrastructure. During heat waves, power plants may operate less efficiently, reducing their output and increasing the cost of electricity production. Additionally, high temperatures can cause increased resistance in power lines, resulting in higher energy losses during transmission and distribution, which further contributes to rising electricity costs. Moreover, extreme temperatures can lead to more frequent and severe weather events, such as wildfires, which can damage power infrastructure and disrupt the supply of electricity. The cost of repairing and upgrading the infrastructure to withstand these extreme weather events is often passed on to consumers in the form of higher electricity rates. To mitigate the impact of extreme temperatures on electricity prices, San Diego has been encouraging the adoption of solar energy. California solar adoption is highest in San Diego County, and transitioning to solar energy can help reduce the demand for electricity from the grid during peak hours, thereby lowering electricity costs for residents. Additionally, solar energy provides a more sustainable and environmentally friendly alternative to traditional power sources, helping to reduce the region's carbon footprint.
