Before we begin, a quick note. The NWPPA morning brief is Generative AI, daily intelligence on the federal and Western developments shaping public power. It isn't human-reviewed before publication, so treat it like any AI tool and verify what you'll act on or cite. Sources are in the show notes. You're listening to the NWPPA morning brief. On today's brief, five federal agencies issue a joint warning on active AI-assisted cyberattacks targeting industrial control hardware common in public power operations. FERC approves a Southwest Power Pool congestion fix with a federal template that could travel west. DOE deploys $500 million to critical minerals and battery manufacturing. Idaho Power opens a second state docket on its $154 million Oregon Territory sale. Montana's Public Service Commission faces a governance fight in court. The Walker River Paiute Tribe and Envy Energy settle a transmission rights of way dispute, and drought stress continues to build across the Colorado River and Rio Grande basins. Today's briefing is brought to you by NWPPA's Northwest Innovations in Communications Conference. September 21st to 24th in Walla Walla, Washington. Four days of storytelling, strategy, and connection for the communicators of public power. Register at NWPPA.org.

SPEAKER_01

The Cyber Attack Advisory is the story today. Five agencies, NSA, CISA, FBI, DOE, and EPA, issued a joint warning that attackers are actively hitting Siemens S7 programmable logic controllers using AI-generated exploitation scripts. These aren't obscure devices. S7 controllers run substation automation and generation controls at public power utilities right now. The multi-agency sign-off and the naming of specific hardware families, every S7 generation from the 200 through the 1500 F series, make this a materially different escalation from general OT security guidance.

SPEAKER_00

This lands Monday morning on operations desks, not regulatory desks. Any utility running S7 hardware in its substation or generation environment needs to know this advisory exists by end of day.

SPEAKER_01

Let's get into it. Start with the cyber attack story in full. The joint advisory covers active exploitation, not theoretical vulnerabilities, using AI-generated scripts to attack the S7 platform. The practical exposure for public power is direct. These controllers are embedded in the infrastructure utilities run every day. What's new here is the AI-assisted attack methodology, which lowers the technical bar for adversaries and broadens the threat pool. The advisory's specificity on hardware families gives operations and security teams a concrete checklist.

SPEAKER_00

The multi-agency designation matters for prioritization. When NSA, CISA, FBI, DOE, and EPA all sign the same document, it signals that the threat intelligence is real and the exposure is cross-sector. Utilities should treat this as actionable intelligence, not background noise. The next step is a direct inventory of S7 deployments against the hardware families named in the advisory.

SPEAKER_01

On August 19th, FERC approved SPP's plan to reduce congestion by reconfiguring how power flows across the existing grid rather than redispatching generators, an approach called topology optimization. A study by New Grid, SPP, and the Brattle Group found the technique could eliminate historical operating limit violations on 75% of the constraints analyzed, with savings estimated at $18 million to $44 million a year. Market participants can propose reconfigurations, and SPP evaluates whether the market as a whole benefits before approving changes.

SPEAKER_00

The Western angle here is the template question. SPP's footprint runs into the Western Dakotas and Montana, so some public power utilities are adjacent to or inside that territory. But the bigger story for the West is whether FERC's approval signals willingness to push this approach into other RTOs and eventually into Western market constructs. Getting more out of existing wire without new construction is a compelling value proposition for any utility facing transmission cost pressure.

SPEAKER_01

Moving to the DOE Critical Minerals Awards, Energy Secretary Chris Wright announced $500 million in grants to seven critical mineral processing and battery manufacturing projects on August 20th. The funding flows from the 2021 Bipartisan Infrastructure Law. DOE had previously canceled several awards from the same program issued under the prior administration. Wright framed the awards as reducing foreign supply chain dependence for materials that underpin grid storage, electric vehicles, and data centers.

SPEAKER_00

For public power utilities planning storage additions or negotiating long lead procurement, a domestic processing base is directly relevant to supply chain risk and project economics. If the projects actually reach commercial scale on the timeline's DOE sites, that last qualifier is the real question. Seven projects awarded is a starting line, not a finish line.

SPEAKER_01

Shifting to the Interior Department's NEPA exemption for forest thinning. For Western public power utilities with service territories running through federal forest land, the policy could accelerate fuels reduction work near transmission corridors and substations that has historically moved slowly through environmental review.

SPEAKER_00

The durability question is real. Categorical exemptions of this scope draw litigation, and the timeline between announcement and actual groundwork depends heavily on whether courts let it stand. The direct utility stakes are wildfire mitigation, cost recovery, and insurance posture, both of which are already under pressure across the rural West.

SPEAKER_01

Over to the Idaho Power Territory sale. Idaho Power filed at the Idaho Public Utilities Commission for approval of its $154 million sale of Oregon Service Territory to Oregon Trail Electric Consumers Cooperative. This opens a parallel state proceeding alongside the Oregon PUC review already underway. Idaho Power currently serves roughly 20,000 customers across four Oregon counties: Malhier, Harney, Baker, and Wallawa. The utility says the sale lets it concentrate resources on Idaho customers amid rising demand.

SPEAKER_00

For the cooperative sector, this is a meaningful territorial expansion, a rural electric cooperative taking on distribution and transmission assets historically held by an investor-owned utility across a significant geographic footprint. Two state commissions now have to approve this, and the sequence and timing of those decisions will determine when Oregon Trail Electric can actually begin planning for the transition.

SPEAKER_01

Next up, the Montana PSC governance fight. Commissioner Brad Molnar asked a Helena district judge for a preliminary injunction, a court order that would halt his suspension while the case is decided, blocking Governor Gianforte's one-year removal. Gianforte suspended Molnar last month following an investigative report finding he made repeated sex-based remarks and retaliated against employees who complained. Molnar denies the allegations and claims political motivation. A judge heard arguments from attorneys for all parties.

SPEAKER_00

The operational concern for utilities and cooperatives with matters before the Montana PSC is commission composition. A pending Northwestern Energy merger and active rate proceedings are already in the queue. Whether the commission operates at full composition while this plays out in court directly affects the pace and dynamics of those proceedings.

SPEAKER_01

Turning to the Walker River Paiute Settlement, the Walker River Paiute Tribe and NV Energy completed negotiations over a trespass dispute involving an expired 1970s Bureau of Indian Affairs Power Line easement, reaching five new right-of-way agreements for the Green Link West Transmission Project. The Tribal Council approved the settlement in early August. The Green Link West Line will run adjacent to the existing route across tribal lands, north and east of Walker Lake. New construction will comply with tribal sales and use tax, possessory interest tax, and the tribal employment rights ordinance.

SPEAKER_00

For Western utilities planning long linear transmission across reservation lands, this settlement is a working precedent on the scope and terms that can close a dispute involving expired easements. The fact that NV Energy also confirmed to tribal leaders that data center proposals in Mason Valley are not part of the discussions shows how carefully these negotiations are being scoped. That kind of explicit boundary setting may matter as utilities design future engagement strategies.

SPEAKER_01

On the drought front, the National Integrated Drought Information System published an August 20th update reporting that multiple years of low reservoir conditions continue to stress surface water storage across both the Colorado River and Rio Grande basins. The update cites record low snowpack, above average temperatures, and a lackluster monsoon season as compounding factors.

SPEAKER_00

For public power utilities and joint action agencies with hydropower stakes in the Colorado system, the operational implications are reduced generation output, tighter reservoir coordination, and continuing pressure on lower basin allocation talks. This is not a news story, but the compounding factors named in this update make clear the stress is deepening, not stabilizing.

SPEAKER_01

On pricing, Front Month Henry Hub Natural Gas Futures were trading at $2.79 per million BTU on August 21st, up from $2.77. NYMEX WTI Front Month Crude Futures were trading at $86.82 per barrel, down from $87.26.

SPEAKER_00

Western spot prices for August 20th delivery. At Sumas, natural gas was $2.89 per million BTU. Mid-Columbia Power was $85.50 per megawatt hour. The 10-year Treasury yield was 4.65% on August 19th, down from 4.71. COMEX Copper settled at $6.61 per pound on August 20th, up from $6.46.

SPEAKER_01

Moving to the congressional scan, Senator Blumenthal introduced the Affordable Electricity Rates Act, which would amend the Federal Power Act to require FERC to consider affordability when setting transmission rates. The bill would treat any transmission rate likely to raise overall retail electricity prices by more than 5% as presumptively failing the just and reasonable standard, FERC's existing legal test for approving rates. Blumenthal also wrote to FERC seeking stronger oversight of what he calls asset condition projects, which he says now represent 73% of annual transmission capital spending in New England.

SPEAKER_00

An affordability overlay on FERC rate making would be a substantial framework shift if enacted. For Western public power utilities that participate in transmission cost allocation debates and rely on FERC jurisdictional interconnection rates, this changes the legal argument structure around rate challenges. It's early stage legislation, but the direction of travel is worth tracking as transmission capital spending continues to climb nationally.

SPEAKER_01

Shifting to the advocacy front, the National Rural Electric Cooperative Association is pressing for repeal of EPA's 2024 greenhouse gas standards for gas-fired power plants. CEO Jim Matheson called the rules 40% capacity factor threshold and the requirement to install carbon capture equipment capturing 90% of emissions by 2032, quote, untenable. EPA sent a proposed repeal rule to the Office of Management and Budget, which reviews significant federal rulemakings before finalization in May. The 90-day review deadline passed in August without action.

SPEAKER_00

The compliance pathway for new gas capacity remains genuinely unsettled. For cooperative and public power utilities planning gas-fired additions to serve rising load, that uncertainty runs directly into resource planning timelines. A rule under proposed repeal with OMB review stalled is not a cleared regulatory runway, and it is not a dead rule either.

SPEAKER_01

On the geothermal front, a Bureau of Land Management lease sale in New Mexico in June netted more than $16.5 million, the second highest grossing geothermal sale in BLM history. The top parcel sold for a record $701 per acre. BLM ran a follow-on Utah geothermal sale on August 18th. Private developer interest in federal geothermal parcels is rising sharply, only 17% of parcels sold at the minimum bid compared to 76% in 2019.

SPEAKER_00

That shift in bidding behavior is a real signal about where private capital sees opportunity in firm, dispatchable resources. For Western public power utilities evaluating geothermal as a resource addition, rising developer interest means more projects potentially reaching power purchase agreement stage, but also more competition for the best federal parcels and the transmission access to move that power.

SPEAKER_01

One to watch. The EPA gas plant greenhouse gas standard situation deserves a closer look than the advocacy scan suggests. The proposed repeal is at OMB, the 90-day review clock expired without action. That means the rule, which mandates 90% carbon capture on new gas plants operating above 40% capacity factor by 2032, remains legally in effect while the repeal process moves at an undefined pace. Any utility that has new gas capacity in its integrated resource plan over the next several years is making planning decisions against a regulatory backdrop that could land in three different places. The rule stands, the rule is repealed, or litigation reshapes it before either of those outcomes.

SPEAKER_00

The capacity factor threshold is the operational trip wire. A plant designed for peaking service may stay below 40%, but a plant built to firm intermittent renewables or serve load growth will likely cross it. The absence of a resolved compliance pathway is itself a resource planning constraint. And the longer OMB sits on the repeal proposal, the more that uncertainty costs in lead time for projects that need to reach financial close in the next two to three years.

SPEAKER_01

Today's picture comes down to two threads. The Cyberattack Advisory is immediate and operational. S7 Hardware Inventory is the starting point. The gas plant rule uncertainty is slower moving, but has longer tails for resource planning across the West. Both reward attention now rather than later.

SPEAKER_00

And the Idaho Power Territory sale is the structural story to watch over the coming months. Two state proceedings, a cooperative sector expansion, and a question about how fast both commissions move. A lot can shift before either approval lands. That's your NWPPA morning brief for Friday, August 21st, 2026. Sources for every story are linked in the show notes. Have a great weekend. Keep the lights on.
