- Avista expects $615 million of utility capital spending in 2026.
A safer utility waiting on regulators
Avista is a classic regulated utility. The best case relies on steady grid spending, fair rate orders, and customer growth across the Pacific Northwest.
The bull case relies on a favorable order from the Washington Utilities and Transportation Commission in December. A secondary lift would come from structuring a special contract to revive the paused 500 MW data center project while protecting existing ratepayers.
The bear case centers on an adverse regulatory order capping returns. This is compounded by the potential permanent loss of the large data center opportunity if acceptable terms cannot be reached, which would limit upside growth.
Rates turn grid spending into earnings
Avista generates, transmits, and distributes electricity and natural gas to homes and businesses. The primary unit is Avista Utilities, which serves customers in Washington, Idaho, and Oregon. AEL&P serves Juneau, Alaska, and is much smaller.
The company makes money by investing in power plants, wires, pipes, meters, and wildfire safety. Those assets become rate base, which is the pool of approved investment on which Avista can earn a regulated return. State utility commissions decide how much customers pay and what return Avista earns.
This model relies on fair regulation. If a rate case allows a lower return or delays cost recovery, Avista may spend money before it can earn enough on that spending. The Washington General Rate Case is currently the biggest test of this dynamic.
The non-regulated investment portfolio is small but has caused noise. In 2025, losses in Other Businesses hurt consolidated earnings, though this segment stabilized in early 2026.
Power, gas, and load growth bets
Electric utility service
Avista sells and delivers electricity to regulated customers. This is the core of the business and depends on fair state rate orders.
Natural gas distribution
The company distributes natural gas in its service areas. Gas adds steady customer demand, but rates still depend on regulators.
Owned generation
Avista uses generation assets such as hydroelectric resources and biomass. The company completed the transfer of its ownership in the Colstrip coal facility at the start of 2026.
Grid and wildfire investment
Spending on wires, pipes, grid hardening, and safety can grow rate base. Wildfire work is a needed cost of serving dry areas.
Large-load customers
Data centers and other big power users could lift demand. The key 500 MW project is paused pending strict ratepayer affordability protections.
2025 All-Source RFP
Avista issued its 2025 All-Source RFP in May 2025. The process could add new owned or contracted resources to meet future demand.
AEL&P
Alaska Electric Light and Power serves Juneau, Alaska. It adds regulated electric earnings to the overall portfolio.
Mostly one utility
Fiscal 2025 operating revenue was $1.964 billion. Avista Utilities produced $1.916 billion, concentrating the company in its main regulated utility.
What could go wrong
Washington rate case squeeze
High impact · Medium oddsAvista's multi-year Washington rate plan is proceeding without a settlement. A weak order in December could lower the allowed return on equity or delay recovery of power supply costs, which would pressure earnings.
500 MW data center delay
High impact · Medium oddsThe paused 500 MW data center project removes the clearest large-load growth catalyst. Avista requires strict affordability and reliability protections before proceeding. Without a revival of this project, growth above the target range looks less likely.
Wildfire and weather costs
Medium impact · Medium oddsAvista serves areas where heat, dry weather, and wind can create wildfire risk. Recent Spokane wildfires damaged transmission infrastructure. While early signs clear the company of starting the fires, weather-related operational impacts remain significant.
Capital plan execution
Medium impact · Medium oddsAvista expects $615 million of utility capital spending in 2026. Spending that money on time and getting it into rates is central to the earnings plan. Regulatory delays would weaken the payoff from that spending.
Non-regulated investment losses
Low impact · Low oddsOther Businesses hurt 2025 earnings through unrealized investment losses, especially in clean technology holdings. That pressure has stabilized, but the portfolio can still create quarter-to-quarter swings.
In one breath
Is Avista a growth stock or an income stock?
Avista is closer to an income and regulated utility stock. Growth depends on rate base investment, fair rate cases, and possible large-load customers such as data centers.
Why does the Washington rate case matter so much?
Washington is a major part of Avista's regulated business. The rate case decides how much of the company's spending can be recovered from customers and what return it can earn.
What is the data center issue at Avista?
Avista had been working with a prospective data center customer with up to 500 MW of incremental load. That project is now paused and requires strict affordability protections for existing ratepayers.
What does rate base mean for Avista?
Rate base is the approved value of utility assets that Avista can earn a return on. When Avista invests in the grid and regulators approve recovery, rate base can grow and support earnings.
