Avista's Double Frontline: Wildfire Damage and Data Center Negotiation Pause

A Community in Flames, a Grid Under Stress

On the August 3 call, CEO Heather Rosentrater opened with the devastating news: multiple wildfires near Spokane had displaced thousands. She emphasized that “our facilities were not involved in starting any of these fires” — Heather Rosentrater, President and CEO · 2026-08-03, but the damage to the transmission and distribution system is real. About 7,300 electric and 5,300 natural gas customers were still without service. The Public Safety Power Shutoffs proved their value—patrols found several trees that had fallen into a de-energized line. “we do think that they were effective in this really high-risk situation” — Heather Rosentrater, President and CEO · 2026-08-03—a rare moment of validation for a controversial tool.

Cost recovery is the immediate investor concern. CFO Kevin Christie noted that many of these are long-lived assets, so regulatory lag should be limited, and securitization likely isn't needed for this scale:

I wouldn't see us being any remotely close to that need.

This wildfire event is new for Avista—the wildfire mitigation plan has been a recurring theme, but actual fires hitting the service territory at this scale is a step change. The stock is already in a drawdown, down 10% over the last 90 days, and this event adds uncertainty.

The Data Center Pause: Protecting the Existing Customer

The second major theme is the development around large load customers. They had a 500 MW project that was previously upside to the capital plan; now it's been pulled. Heather was explicit: “we will not move forward with a new large data center customer unless we're confident that they will make significant contributions to support affordability for existing customers.” — Heather Rosentrater, President and CEO · 2026-08-03 The data center negotiation pause is about ensuring a net benefit for current customers—a term they've used before, but now it's front and center as they work with regulators on hybrid tariffs and special contracts.

This is a contrast to the prior optimistic tone. In the May call, they were working toward a May 31 MOU with a customer. Now that MOU is paused, and the company is engaging in workshops and internal reviews. “We expect that there needs to be a net benefit for our current customers, and we want to ensure that there are protections in place” — Heather Rosentrater, President and CEO · 2026-08-03—that's the new mantra.

That's a company-unique shift—they're deliberately slowing down growth to protect affordability, which is a nuanced stance in a sector where load growth is coveted.

Rate Case and Financial Backdrop

The Washington rate case is heating up. Kevin Christie said that a settlement "will be quite difficult" because of fundamental differences on the 4-year term. “Staff's perspective on power supply, again, a little bit of a discrepancy on how we get there, but it's relatively close to where the company is at.” — Kevin Christie, Senior Vice President, CFO, Treasurer and Regulatory Affairs Officer · 2026-08-03 So the case is moving to litigation, with hearings in September and an order expected in December. “We shared that we are working towards a May 31 date for an MOU” — Heather Lynn Rosentrater, Executive (likely a senior executive or officer) · 2026-05-05—but that was then; now the pause has changed everything.

Financially, the utility is holding up. Operating income rose 7% year-over-year to $134 million in Q1 2026, and the operating margin is up 3.2 percentage points. The nonregulated portfolio, particularly the EIP fund and its investment in ERock, is generating gains—though Kevin warned of volatility. “we would expect another gain due to the lag that would show up next quarter and it will introduce volatility” — Christopher Ellinghaus, Analyst · 2026-08-03.

The company is also working to manage equity needs; as Kevin said in the prior call, “we would expect a 50-50 capital structure or funding approach” — Kevin Christie, CFO · 2026-02-25 for incremental capital. That's still the plan, but the data center pause reduces some of that urgency.

What Changed?

Two things: a tangible wildfire event that hits the service territory, and a deliberate cooling of the data center growth story. Both are company-unique shifts, not boilerplate. The wildfire is an operational risk being managed; the data center pause is a strategic choice that could have long-term implications for rate base growth. The company is in a 90-day drawdown, and the market is trying to price in both the uncertain cost recovery and the slower growth.

In the global context, "data centers" and "wildfire" are both recurring themes, but for Avista, the focus on affordability and net benefit is a notable pivot. The fundamentals remain solid, but the events add a layer of risk.
