New Rates Support Investments in Safe, Reliable Service
New, higher electric rates for Tucson Electric Power customers took effect Sept. 1, 2023 to help cover rising costs and support recent investments in safe, reliable service. The new rates:
- recover the cost of grid improvements, technology and security upgrades, new wind and solar power resources, and other investments made since 2018, the year reflected in our current rates;
- pass along higher energy and operating costs; and
- help us serve the increasing energy needs of our growing community.
The proposal was approved by the Arizona Corporation Commission, a five-member elected panel that sets the rates charged by public service providers.
The new rates are expected to increase the average monthly bills of residential customers with typical usage on TEP’s Basic pricing plan by about $11. That change varies with usage. Customers can mitigate that impact by saving energy, possibly in combination with Time-of-Use pricing plans that offer lower rates during off-peak periods.
Managing Higher Costs
TEP has been working hard to manage costs in the face of rising prices for equipment, parts, construction materials and other necessities. Due to ongoing inflation, consumer prices are now more than 15 percent above the levels reflected in TEP’s rates.
“The cost of providing safe, reliable service is increasing rapidly as inflation exacerbates the impacts of supply chain challenges, regional energy capacity constraints and more extreme weather,” said Susan Gray, TEP’s President and CEO. “Our rates are needed to support systems and infrastructure that protect and upgrade our grid, expand our use of cleaner energy and help us serve the expanding energy needs of our growing community.”
Peak energy demands on our local grid have increased 5.7 percent since 2019, driven by hotter summer weather and the addition of more than 14,000 homes and businesses over the past three years. The cost of fuel and wholesale energy also has increased significantly, driving up costs that we pass along to customers without any markup.
Despite these challenges, TEP has provided top-tier reliability through the ongoing coronavirus pandemic. We continue to rank in the top quartile of all electric utilities across the country for service reliability. We’ve also connected record numbers of rooftop solar arrays to our system and have made upgrades to our local distribution grid that allow us to accommodate even more.
Supporting Cleaner Energy
The rates support investments that will reduce our long-term energy costs through increased use of wind and solar power systems that will generate 70 percent of our power by 2035.
Those steps will help us end our use of coal and achieve an 80 percent reduction in carbon dioxide emission reductions by 2035, key objectives articulated in our most recent Integrated Resource Plan. Our plan will help avoid the production of more than 50 million tons of carbon dioxide over 15 years – equivalent to taking three-quarters of a million cars off the road.
TEP’s monthly Lifeline low-income discount increases from $18 to $20 under the newly approved rates for qualifying residential customers whose household income does not exceed 200 percent of the federal poverty level.
TEP has supported customers and our community during the ongoing pandemic through increased philanthropic giving, delayed recovery of higher energy expenses, direct bill credits and a campaign to connect qualifying customers to expanded federal aid and other bill payment assistance – efforts that have included door-to-door visits. Including all federal funding, contributions and other resources, TEP has directed nearly $33 million in assistance to customers and our community since 2020.
“We know higher costs can be hard to face, which is why we offer so many ways to help customers who are having difficulty paying their bills,” Gray said. “We really need higher rates to begin recovering the increased costs of providing safe, reliable service that keeps pace with our customers’ expanding energy needs.”
