Cycle on Aug 17, 2026

I am going to check the open threads on this topic to see what specific questions or watches need to be addressed in this cycle.

I am going to read the existing notes for the topic to see what has already been documented and understand the structure of the existing findings.

I see a few very interesting threads: 1. `019fc6bf-24db-7a1d-92c1-d650b023b348` - "FERC Large-Load Interconnection Show-Cause Deadline" (August 17, 2026 deadline for regional grid operators to respond to Section 206 show-cause orders on large-load interconnection tariffs). Today is August 17, 2026. This is exactly the day of the deadline! 2. `019f5a96-90e2-7c84-b08d-97328f23d33d` - "Oregon PUC Decision on Amazon and DCC Reconsideration of Schedule 96" (reconsideration due by Sept 4, 2026). 3. `019eee6e-7999-77fb-81a7-d30d411389c0` - "Louisiana PSC Decision on Entergy's Seven New Gas Plants for Meta". 4. `019eca69-825a-7c29-b776-0fa0f8768504` - "PJM Accelerated Backstop Reliability Auction Results" (expected Sept 2026). 5. `019feacb-b904-7a31-8234-1a5610975394` - "PUCO Staff Report on FirstEnergy's Proposed Ohio Data Center Tariff (Schedule DCT)" (due Nov 30, 2026). 6. `019fa2ae-d1b6-76c4-b262-a8243cc17d1d` - "PUCO Decision on FirstEnergy's Proposed Ohio Data Center Tariff (Schedule DCT)". 7. `019f7ea1-964c-7859-a3db-184c934fec57` - "Louisiana LED Releases Ratepayer and Community Protection Framework for Data Centers" (due by Sept 25, 2026). Let's do some searches. First, let's search for the FERC Section 206 show-cause orders on large-load interconnection tariffs or regional grid operators (PJM, MISO, SPP, CAISO, ISO-NE, NYISO) responding to FERC on large-load interconnection. Let's also look up what's happening with the FERC August 17, 2026 deadline. Let's also search for news on some of the core companies: Constellation (CEG), Vistra (VST), Talen (TLN), NRG, Southern (SO), Dominion (D), AEP. Let's first search about the FERC show-cause orders on large-load interconnection.I will search the web for the FERC large-load interconnection show-cause order responses or filings, specifically looking for grid operators responding to FERC's Section 206 orders on large-load tariffs around August 17, 2026.

Let's do a search specifically for "August 17, 2026" or "August 2026" and "FERC" "show cause" or "EL26-67" to see if there are any filings or news about RTOs/ISOs responding. Wait, let's look at the dates. The FERC orders were issued on June 18, 2026. 60 days from June 18, 2026 is exactly August 17, 2026! Let's see if we can find any filings or press releases from today (August 17, 2026) or the last few days. I'll use `web_search` with `recent=true` or freshness="week" or "month" to see if there are any updates or if RTOs requested extensions or made filings. I'll search for "EL26-67" or "EL26-70" or "EL26-68" or "EL26-69" or "EL26-71" or "EL26-72" or "show cause" "FERC". I'll also check if there is an extension of time.I will search for RTO/ISO filings or extension requests related to the FERC show-cause orders (dockets EL26-67, EL26-68, EL26-69, EL26-70, EL26-71, EL26-72) in the last few weeks.

Ah, let's fetch the URL `https://distroforge.com/blog/large-load-resource-adequacy-six-rto-filings/` and `https://www.climatesolutionslaw.com/2026/07/rtos-and-isos-answer-a-national-preview-of-how-all-six-grid-operators-plan-to-respond-to-the-large-load-surge/` to see what RTOs and ISOs have filed. Wait, let's also search for "Large Load Resource Adequacy: What Six RTOs Told FERC" or fetch `https://distroforge.com/blog/large-load-resource-adequacy-six-rto-filings/`. This looks extremely relevant! It says "What Six RTOs Told FERC" and covers MISO, CAISO, and others. Let's do a fetch.I will fetch the Distroforge article on what the six RTOs told FERC regarding large-load resource adequacy.

This

I will call the `market_view` tool for Vistra Corp (ticker: VST) to see its current public-markets data, which represents one of the core merchant utilities in our topic brief.

I will also call `market_view` for Constellation Energy (ticker: CEG) to get a complete view of the core merchant nuclear and independent power producers that are highly exposed to this trend.

Excellent. Now let's do a search on Oregon's Schedule 96, Portland General Electric (PGE), Amazon, or the Data Center Coalition (DCC) application for reconsideration, which had a deadline of September 4, 2026. Let's see if there are any recent filings or developments. I'll search for "Portland General Electric" "Schedule 96" or "Docket UM 2377" or "Amazon" "reconsideration".I will search for any recent developments regarding Portland General Electric's Schedule 96 tariff, the Oregon PUC, Amazon, or the Data Center Coalition's applications for reconsideration.

Ah, let's search for "UM 2377" "reconsideration" or search for "reconsideration" within the Oregon PUC site or using web_search. Let's see what the Data Center Coalition or Amazon are asking for in their reconsideration. Let's do a search.I will search for the specific arguments and details of the applications for reconsideration filed by Amazon and the Data Center Coalition regarding Portland General Electric's Schedule 96 tariff under Oregon PUC Docket UM 2377.

Ah, look at that! The file `um2377hag347457029.pdf` is titled "AMAZON DATA SERVICES, INC.'S APPLICATION FOR REHEARING OR RECONSIDERATION". And the URL is `https://apps.puc.state.or.us/edockets/edocs.asp?FileType=HAG&FileName=um2377hag347457029.pdf&DocketID=24470&numSequence=222`. Let's see if we can fetch this PDF or search for its content, or search for its main arguments. Since it's a PDF, we might not be able to fetch it directly with `web_fetch` if it's too large or binary, but let's try or search for news/summaries of it. Wait, let's search for "AMAZON DATA SERVICES, INC.'S APPLICATION FOR REHEARING OR RECONSIDERATION" to see if we can find a summary or write-up of their arguments, or let's search for "um2377hag347457029.pdf" text. Let's do a search.I will search for summaries or quotes from Amazon's Application for Rehearing or Reconsideration in Docket UM 2377 to understand their specific objections to Portland General Electric's Schedule 96 large-load tariff.

Let's search for "DCC's Application for Rehearing or Reconsideration" or "ADS's Application for Rehearing or Reconsideration" on Google to see if we can find any articles or legal briefs that summarize the key legal issues or arguments raised by Amazon and the Data Center Coalition. Wait! Let's try to `web_fetch` the first few pages of `https://apps.puc.state.or.us/edockets/edocs.asp?FileType=HAG&FileName=um2377hag347457029.pdf&DocketID=24470&numSequence=222`. Since it's a PDF, `web_fetch` might return markdown if the server converts it, or it might fail. Let's see if it works. I'll call it.I will attempt to fetch the PDF of Amazon's application for rehearing or reconsideration from the Oregon PUC website to see if its text can be extracted.

This is an incredible primary document! It lays out the entire legal battle in Oregon over Portland General Electric's (PGE) Schedule 96 large-load tariff and the "Large Energy Use Facility" (LEUF) interconnection queue. Let's analyze what we have here: - **Oregon's Landmark "Growth Pays for Growth" / LEUF Interconnection Queue**: - The Oregon Public Utility Commission (OPUC) issued Order No. 26-154 in Docket UM 2377 (entered May 7, 2026, though the PDF says "Order No. 25-154... entered May 7, 2026", wait, the PDF says "entered May 7, 2026" and mentions "Order No. 26-153 issued on the same day", so it's actually 2026. The text of the PDF says: "Order No. 25-154 of the Public Utility Commission (the “Commission”) in UM 2377, entered May 7, 2026..."). - The OPUC order mandated that Portland General Electric (PGE) establish an **interconnection queue solely for Large Energy Use Facilities (LEUF)** (loads above 20 MW). - Under this queue, PGE is *precluded* from serving a new large load customer if doing so would impede the utility's ability to meet its clean energy targets under **HB 2021** (which requires 100% emissions reduction by 2040). - Essentially, the queue "pauses" large load energization if the load cannot be met without increasing PGE's carbon emissions. - To bypass or "avoid" the queue, a customer must establish an "HB 2021-compliant plan of service" using alternative pathways: load flexibility, special contracts, voluntary renewable energy tariffs (VRET), direct access (retail choice) with non-emitting resources, or onsite/behind-the-meter generation. - **Amazon's Legal Challenge / Application for Reconsideration**: - On **July 6, 2026**, Amazon Data Services (ADS) filed an **Application for Rehearing or Reconsideration** of Order No. 26-154 (or 25-154 as cited). - **Key Legal Objections**: 1. **Violation of the Statutory "Obligation to Serve"**: Amazon argues that the OPUC has subordinated PGE's fundamental, long-standing statutory obligation under ORS 757.020 to "furnish adequate and safe service" to its HB 2021 emission targets. They state that the POWER Act (HB 3546 / ORS 757.292) only allows the Commission to consider whether *rates* impede clean energy goals, not to condition *service* or create an interconnection queue that delays or denies service. 2. **Undue Discrimination**: Amazon points out that all load growth increases emissions, yet only LEUFs (data centers) are singled out for a service pause, which constitutes undue discrimination. 3. **Illegal Shifting of Utility Obligations**: Amazon argues that HB 2021 targets are legally imposed on the *utility* (PGE), but the queue illegally shifts the burden of compliance onto the *customer* as a condition of receiving service. 4. **Infeasibility of Alternative Pathways (Direct Access Cap)**: Amazon notes that the OPUC's Order No. 26-153 on Direct Access (issued the same day under Docket UM 2024) places strict limits on Direct Access, including requiring Electricity Service Suppliers (ESSs) to participate in regional resource adequacy programs (like WRAP) that *do not yet exist in a binding form*, making Direct Access functionally unavailable as an "escape route" from the queue. 5. **Tension with FERC's Section 206 Show-Cause Orders**: Amazon argues that the OPUC's LEUF queue is in direct tension with FERC's June 18, 2026 show-cause orders (Dockets EL26-67 through EL26-72), which seek to ensure that large loads have *non-discriminatory* access to the grid. Let's check if there are other filings or decisions in Oregon. The OPUC decision on the reconsideration is due around September 4 or 5, 2026. This is a crucial dated catalyst that we have a watch for! Let's see if we can find any other information. Wait, let's look at the other grid operators' filings. According to the Distroforge article: - **ISO New England (ISO-NE)** filed its report in **EL26-72** proposing **BYONG ("Bring Your Own New Generation")** and excluding large loads from the Installed Capacity Requirement (ICR) system load forecasts. This means that the capacity market will *stop* buying capacity on behalf of large loads. They become responsible for bringing their own energy supply or accepting curtailment. - **MISO (EL26-70)** proposed a **Zero Injection Generator Interconnection Agreement (ZI-GIA)** and a **Large Load Parallel Study Process** (for loads $\ge$ 250 MW, studied alongside associated generation, with generation capped at 150% of load, targeting a fast 120-day timeline). - **SPP (EL26-68)** proposed **Price Adaptive Load (PAL)** and **Price Adaptive Load Service (PALS)**, and already has CHILLS (Conditional High Impact Large Load Service) which allows long-term non-firm service up to 7 years. - **PJM (EL26-67)** proposed its **Reliability Backstop Procurement (RBP)** framework. - **CAISO (EL26-71)** is using a **Large Load stakeholder initiative** as its compliance vehicle. Let's search for "ISO New England" "BYONG" or "Bring Your Own New Generation" or "Installed Capacity Requirement" "large loads" to find more details about this landmark proposal! This is incredibly interesting because it represents a complete shift in who pays and how capacity is procured. In ISO-NE, they are proposing to exclude large loads from the capacity market's demand curves entirely. This protects existing ratepayers from capacity price spikes, but shifts all generation procurement costs directly onto developers. Let's do a search on this.I will search for more information on ISO New England's "BYONG" (Bring Your Own New Generation) or "Bring Your Own Generation" (BYOG) proposal and its exclusion of large loads from the Installed Capacity Requirement (ICR).

Let's fetch the PDF of ISO New England's report to FERC: `https://www.iso-ne.com/static-assets/documents/100037/a04.2_tc_ferc_informational_report_resource_adequacy_large_loads.pdf`. This is a primary source from the FERC show-cause docket EL26-72! Let's do a fetch. I want to see the details of how they define BYOG and the Installed Capacity Requirement (ICR) exclusion. This is incredibly high-quality evidence.

This is an incredibly rich document. Let's look at the key details of ISO-NE's response to FERC in Docket No. EL26-72-000, filed on July 20, 2026: - **"Bring Your Own New Generation" (BYONG)**: ISO-NE proposed to require that new large loads (e.g., data centers) "bring their own" incremental new generation to serve their demand. They plan to model this on the Southwest Power Pool's (SPP) **Conditional High Impact Large Load Service (CHILLS)** rules. - Under CHILLS, a large load can receive energy on a long-term non-firm basis (subject to flexibility requirements and/or curtailment and interruption) for up to 7 years while designated resources and network upgrades are being built. - This ensures that a large load cannot adversely impact the reliability of traditional load during stressed grid conditions. - **Capacity Market Exclusion (Installed Capacity Requirement - ICR)**: - This is a massive structural change. ISO-NE proposes to **exclude new large loads from the system load forecasts used to set the capacity market's demand curves and the Installed Capacity Requirement (ICR)**. - This means the capacity market will **not** procure incremental capacity on behalf of new large loads, and existing ratepayers will not be billed for the capacity needed to serve them. - Instead, the large loads are entirely responsible for their own energy supply and capacity. - **Timeline**: - ISO-NE intends to put eligible customers on notice of these two concepts (BYONG and capacity market exclusion) in its compliance filing to the June 18 Order (due November 16, 2026, as noted by Distroforge). - Detailed supporting rules and tariffs implementing these concepts will be filed in **2027** after stakeholder and state consultation. Let's review the other dockets. Let's see if we can find any information about the FERC large load interconnection show-cause orders' actual filings from today or the last few days (August 17, 2026 is the deadline). Wait, let's search for MISO's filing. In the Distroforge article, MISO has Docket **EL26-70**. MISO proposed a **Zero Injection Generator Interconnection Agreement (ZI-GIA)**, plus a **Large Load Parallel Study Process** on July 31 and end of September 2026. Let's search for "MISO" "Zero Injection" "Large Load Parallel Study Process" or "EL26-70" to see what they actually filed or proposed.I will search for MISO's filings in Docket EL26-70 and its proposed "Zero Injection Generator Interconnection Agreement" and "Large Load Parallel Study Process".

This is very helpful. Let's see what else is happening. We have a thread: - `019f7ea1-964c-7859-a3db-184c934fec57` - "Louisiana LED Releases Ratepayer and Community Protection Framework for Data Centers" (due by Sept 25, 2026). - `019eee6e-7999-77fb-81a7-d30d411389c0` - "Louisiana PSC Decision on Entergy's Seven New Gas Plants for Meta" (Entergy Louisiana's fast-tracked application to build and operate seven new natural gas-fired power plants to serve Meta's Hyperion AI data center in Richland Parish). Let's search for "Entergy Louisiana" "Meta" or "Hyperion" "gas plants" or "natural gas" "LPSC" or "Louisiana Public Service Commission" to see what's happening. In our notes we have: `louisiana-ai-data-center-power-boom` - "Louisiana AI Data Center Power Boom: Cottonwood Purchase Indefinitely Postponed Amid Intense Ratepayer Backlash" (updated Aug 10, 2026). Let's search for recent updates on Louisiana, Entergy Louisiana, and Meta's data center.I will search for updates on Entergy Louisiana's proposed natural gas-fired power plants to serve Meta's AI data center in Richland Parish and the Louisiana Public Service Commission's actions.

This is incredibly interesting. Let's do a search to see if the LPSC made a decision on Entergy's application for the seven new gas plants in July or August 2026. Wait, let's look at the dates. The article from June 23, 2026 says: "The Public Service Commission's next meeting is Aug." And the Entergy press release from March or April 2026 says: "Entergy Louisiana today announced an additional agreement with Meta... Seven new natural gas-fueled combined-cycle power plants totaling more than 5,200 megawatts... This project will also be the first submitted under the Louisiana Public Service Commission's newly adopted Lightning Amendment... Management will discuss this announcement... on the first-quarter 2026 earnings call scheduled for April 29, 2026." Wait, let's search for "Entergy Louisiana" "seven" "natural gas" "LPSC" "August 2026" or "July 2026" to find the outcome or status of this application. Is there a decision? Let's see if there is any news on the Louisiana PSC meeting in July or August 2026 regarding these 7 gas plants.I will search for the Louisiana Public Service Commission's recent decisions or meetings in July and August 2026 concerning Entergy's application to build seven new gas plants for Meta.

Wait! Let's examine the dates and details of these filings and articles. The article from "all4energy.org" (Alliance for Affordable Energy) says: "On August 20th, our 5 elected Louisiana Public Service Commissioners are expected to make a decision that will impact the cost of our electricity bills for decades... The Louisiana Public Service Commission is rushing consideration of Entergy Louisiana's application to build 3 new gas plants to serve Meta's data center near Monroe". Wait! Let's check the date of that post: it says "08.06.2026" (August 6, 2026). But let's look at another press release: "Entergy Louisiana announces a new agreement with Meta that will deliver an additional $2B in customer savings... Seven new natural gas-fueled combined-cycle power plants totaling more than 5,200 megawatts... This project will also be the first submitted under the Louisiana Public Service Commission's newly adopted Lightning Amendment." Wait, let's search for "U-37563" or the actual docket number of Entergy Louisiana's application for the seven new gas plants. Let's do a search on the LPSC docket portal or search Google for `Entergy Louisiana Meta "seven" "natural gas" docket`. Let's see if we can find the docket number or the actual status of this application. It says "The state Public Service Commission voted 4-1 to fast track Entergy and Meta's application...". Let's search for `Entergy Louisiana "seven" "natural gas" docket` or `"U-37425"` or `"U-37563"`. Let's do a search.I will search for the specific docket number and status of Entergy Louisiana's application for the seven new natural gas plants under the LPSC's "Lightning Amendment" or "Lightning Initiative" for Meta's data center.

Ah, the search budget is spent. That is perfectly fine, we have an extraordinary amount of rich, primary-source, and up-to-date evidence! Let's review what we have: 1. **The Oregon Public Utility Commission (OPUC) Schedule 96 Landmark Battle**: - Under Docket **UM 2377**, the OPUC issued Order No. 26-154 (entered May 7, 2026) establishing Portland General Electric's (PGE) landmark Schedule 96 large-load tariff (effective July 8, 2026). - This order created a **Large Energy Use Facility (LEUF)** (loads above 20 MW) interconnection queue. - Under the queue rules, PGE is *precluded* from serving a new large load customer if doing so would impede the utility's ability to meet its clean energy targets under **HB 2021** (which requires 100% emissions reduction by 2040). - The queue "pauses" large load energization if the load cannot be met without increasing PGE's carbon emissions. - On **July 6, 2026**, Amazon Data Services (ADS) filed an **Application for Rehearing or Reconsideration** of Order No. 26-154. - Amazon's key arguments are: 1. **Subordination of the Obligation to Serve**: The OPUC has subordinated PGE's fundamental, long-standing statutory obligation to "furnish adequate and safe service" to its HB 2021 emission targets. They argue that the POWER Act (HB 3546 / ORS 757.292) only allows the Commission to consider whether *rates* impede clean energy goals, not to condition *service* or create an interconnection queue that delays or denies service. 2. **Undue Discrimination**: Only LEUFs (data centers) are singled out for a service pause, which constitutes undue discrimination since all load growth increases emissions. 3. **Illegal Shifting of Utility Obligations**: HB 2021 targets are legally imposed on the *utility* (PGE), but the queue illegally shifts the burden of compliance onto the *customer* as a condition of receiving service. 4. **Infeasibility of Alternative Pathways (Direct Access Cap)**: The OPUC's Order No. 26-153 on Direct Access (issued the same day under Docket UM 2024) places strict limits on Direct Access, including requiring Electricity Service Suppliers (ESSs) to participate in regional resource adequacy programs (like WRAP) that *do not yet exist in a binding form*, making Direct Access functionally unavailable as an "escape route" from the queue. 5. **Tension with FERC's Section 206 Show-Cause Orders**: The OPUC's LEUF queue is in direct tension with FERC's June 18, 2026 show-cause orders (Dockets EL26-67 through EL26-72), which seek to ensure that large loads have *non-discriminatory* access to the grid. - This is highly relevant to our watch `019f5a96-90e2-7c84-b08d-97328f23d33d` ("Oregon PUC Decision on Amazon and DCC Reconsideration of Schedule 96"), which has a fire date of Sept 5, 2026. We should update the note `oregon-pwr-act-pge-schedule-96-tariff` to include these detailed legal arguments and update our understanding of the battle. 2. **FERC Section 206 Show-Cause Orders on Large-Load Interconnection (EL26-67 through EL26-72)**: - On June 18, 2026, FERC issued tailored show-cause orders under Section 206 of the Federal Power Act to all six major regional grid operators (PJM, SPP, NYISO, MISO, CAISO, ISO-NE), giving them 60 days to either prove their current tariffs are just and reasonable for large energy users or file changes. - On **July 20, 2026**, all six grid operators filed their large-load resource adequacy reports with FERC. - **ISO New England (ISO-NE)** (Docket **EL26-72**) proposed a landmark **"Bring Your Own New Generation" (BYONG)** (or BYOG) requirement and proposed to **exclude new large loads from the system load forecasts used to set the capacity market's demand curves and the Installed Capacity Requirement (ICR)**. This means that the capacity market will *stop* buying capacity on behalf of large loads. They become responsible for bringing their own energy supply or accepting curtailment. - **MISO** (Docket **EL26-70**) proposed a **Zero Injection Generator Interconnection Agreement (ZI-GIA)** (covering generation serving only load at the same substation and never injecting onto the broader transmission system, capping network upgrades at the substation level) and a **Large Load Parallel Study Process** (for loads of 250 MW or more, studied alongside associated generation, with generation capped at 150% of the identified load need, targeting a fast 120-day timeline). - **SPP** (Docket **EL26-68**) proposed **Price Adaptive Load (PAL)** and **Price Adaptive Load Service (PALS)**, and already has CHILLS (Conditional High Impact Large Load Service) which allows long-term non-firm service up to 7 years. - **PJM** (Docket **EL26-67**) proposed its **Reliability Backstop Procurement (RBP)** framework. - **CAISO** (Docket **EL26-71**) is using a **Large Load stakeholder initiative** as its compliance vehicle. - The August 17, 2026 deadline is the 60-day show-cause response deadline, where operators defend their existing tariffs or propose revisions. The real tariff rewrites will land later (e.g., ISO-NE, CAISO, and SPP have named November 16, 2026 as the date for filing proposed changes under Section 205, with detailed implementing rules arriving in 2027). - This directly resolves our watch `019fc6bf-24db-7a1d-92c1-d650b023b348` ("FERC Large-Load Interconnection Show-Cause Deadline"). Let's record the event and resolve this watch! 3. **Louisiana AI Data Center Power Boom & Meta's 7+ GW Load**: - In Louisiana, the scale of Meta's Hyperion AI data center in Richland Parish is expanding massively. - **Meta Phase 1 (Docket U-37425)**: Approved on August 20, 2025 (4-1 vote), allowing Entergy Louisiana to build three new gas plants and several transmission facilities. - **Meta Phase 2 (Docket U-37882)**: Filed on **March 27, 2026** (Project Evest). Entergy Louisiana announced an additional agreement with Meta to build **seven additional combined-cycle gas plants** totaling more than **5,200 MW** of capacity, along with 240 miles of new 500kV transmission lines, battery storage at three locations, nuclear uprates, and up to 2,500 MW of Meta-funded renewables. - **LPSC Lightning Initiative (Lightning Amendment)**: This application was submitted under the LPSC's newly adopted Lightning Amendment, a fast-track framework designed to bypass longstanding competitive bidding requirements and market assessments to support large-scale economic development. - **Ratepayer Protection Concerns & Backlash**: - On **August 4, 2026**, a coalition of advocacy groups (including the Alliance for Affordable Energy, the Union of Concerned Scientists, and others) filed challenges to Entergy Louisiana's proposal to build these seven new gas plants. - Critics warn that the 10 total gas plants (3 from Phase 1, 7 from Phase 2) totaling over 7,500 MW of power—enough to power New Orleans six times over—could become a massive burden to ratepayers. - Although Entergy and Meta claim Meta is paying its full cost of service and will deliver $2 billion in savings over 20 years, ratepayer advocates highlight that fuel and operating costs, a $550 million 500kV transmission line, and post-contract asset costs (after Meta's 15-year contract ends) could still fall on residential ratepayers. - This is highly relevant to our watch `019eee6e-7999-77fb-81a7-d30d411389c0` ("Louisiana PSC Decision on Entergy's Seven New Gas Plants for Meta") and the note `louisiana-ai-data-center-power-boom`. Let's update that note. Let's write these findings! Wait, let's look at the existing notes and their slugs: - `oregon-pwr-act-pge-schedule-96-tariff` -> Let's update this note to include Amazon's detailed legal challenge/reconsideration arguments. - `louisiana-ai-data-center-power-boom` -> Let's update this note to include the massive Phase 2 filing (Docket U-37882) for 7 additional gas plants (5,200 MW) under the "Lightning Amendment" and the subsequent ratepayer coalition backlash in August 2026. - Let's create a new note for the FERC Section 206 Show-Cause filings, or update an existing one if it fits. Do we have an existing one? Let's check the list of existing notes: - `regulatory-backlash-data-center-ratepayer-protections` (Regulatory and Legislative Backlash) - `pjm-deploys-reliability-backstop-procurement-framework` - `ferc-approves-pjm-capacity-price-collar-extension` Let's check if we can create a new note specifically for the FERC Section 206 Show-Cause RTO/ISO filings and the landmark "Bring Your Own New Generation" (BYONG) and Capacity Market Exclusion proposals. Let's choose a durable slug: `ferc-section-206-large-load-interconnection-rto-filings`. This is a durable subject: the federal-regional grid operator coordination on large-load interconnection. Let's carefully write these notes. First, let's write `oregon-pwr-act-pge-schedule-96-tariff`. Wait, let's read the current content of `oregon-pwr-act-pge-schedule-96-tariff` if possible, but we don't have a direct tool to read the full note body other than `read_notes` which only returned a preview. Let's write the updated note body, keeping the core of what was there and adding the rich new details from the July 6, 2026 Amazon Application for Reconsideration. Wait, let's write `oregon-pwr-act-pge-schedule-96-tariff`. Let's make sure it has the required structure: - Title as `# Title` - 1-2 representative verbatim quotes with links - Sources block at the bottom - No YAML frontmatter. Let's check the first note: `oregon-pwr-act-pge-schedule-96-tariff`. Let's draft it. Wait, the title is "Oregon Implements Landmark 'Growth Pays for Growth' Data Center Tariff Under POWER Act" (or we can keep it similar). Let's write it.I will write the updated note for the Oregon Schedule 96 tariff and Amazon's legal challenge, reusing the slug `oregon-pwr-act-pge-schedule-96-tariff`. This note captures the core legal arguments and structural tensions between state clean energy mandates and the traditional utility "obligation to serve."

I will write the updated note for the Oregon Schedule 96 tariff under Docket UM 2377, incorporating Amazon's detailed July 6, 2026 legal challenge and application for reconsideration.

I will write a new note to document the regional grid operators' responses and filings to the FERC Section 206 show-cause orders on large-load interconnection. This is a crucial federal-level development that shapes how data centers will connect to the grid, including ISO New England's landmark "Bring Your Own New Generation" (BYONG) and Capacity Market Exclusion proposals, and MISO's "Zero Injection" fast-track process. I will use the slug `ferc-section-206-large-load-interconnection-rto-filings`.

I will update the existing note `louisiana-ai-data-center-power-boom` to incorporate Meta's massive Phase 2 expansion (Docket U-37882, "Project Evest"), which proposes building seven additional gas-fired power plants (over 5,200 MW of capacity) under the LPSC's newly adopted "Lightning Amendment," and the subsequent ratepayer coalition backlash in August 2026. This is a crucial, high-exposure development in Louisiana's electricity market.

Now let's review the watches and threads. We have: 1. `019fc6bf-24db-7a1d-92c1-d650b023b348` - "FERC Large-Load Interconnection Show-Cause Deadline" (August 17, 2026 deadline). Today is exactly August 17, 2026! The grid operators have filed their reports on July 20, 2026, outlining their plans and timelines, and today is the official show-cause response deadline. This watch has fired and is resolved. Let's call `record_event` on this watch to close it. Wait, let's look at the parameters for `record_event`: - `thread_id`: `019fc6bf-24db-7a1d-92c1-d650b023b348` - `cycle_id`: `ce6fa86c-093d-4698-8319-c135051ec7ec` - `summary`: "All six RTOs/ISOs filed their large-load resource adequacy reports with FERC by the August 17, 2026 deadline." - `outcome`: "RTOs filed reports on July 20, 2026, proposing landmark reforms like ISO-NE's BYONG and capacity market exclusion, and MISO's Zero Injection fast-track process." - `resolves`: `true` (it's a one-shot watch) - `salience`: 5 (very high importance) Let's do this first.

Now let's resolve the thread `019fc6bf-24db-7a1d-92c1-d650b023b348` with `resolve_thread`. Let's do that.

Now let's check other watches we should register. Wait! Since the grid operators have named **November 16, 2026** as their filing target for proposed tariff revisions under Section 205 (such as ISO-NE, CAISO, and SPP) and detailed implementing rules in **2027**, we should register a new watch for these upcoming filings. Let's see: - ISO-NE, CAISO, and SPP are targeting **November 16, 2026** to file their proposed Section 205 tariff changes. - MISO is targeting the end of **September 2026** for its Large Load Parallel Study Process filing. Let's register a new watch for these upcoming filings. Let's use `record_watch`: - `topic_id`: `019e89cc-63bd-7bf7-9468-ba5ee76fd2d8` - `cycle_id`: `ce6fa86c-093d-4698-8319-c135051ec7ec` - `title`: "RTO/ISO Section 205 Compliance Filings on Large-Load Tariffs" - `cardinality`: "one_shot" - `watch_type`: "dated_catalyst" - `fire_date`: "2026-11-16T00:00:00Z" - `description`: "ISO-NE, CAISO, and SPP are scheduled to file their proposed Section 205 tariff changes on large-load interconnection and resource adequacy by November 16, 2026. MISO is also expected to file its Large Load Parallel Study Process by late September 2026." Let's register this watch.

Now, let's look at Louisiana. We have a watch `019eee6e-7999-77fb-81a7-d30d411389c0` ("Louisiana PSC Decision on Entergy's Seven New Gas Plants for Meta"). The LPSC is under pressure due to the "Lightning Speed" / "Lightning Amendment" initiative, but since a formal coalition challenge was launched on August 4, 2026, we should keep this watch open and see when the LPSC actually rules on Docket U-37882. Wait, let's check if there are any other threads we can resolve or update. We have updated: - `oregon-pwr-act-pge-schedule-96-tariff` (Oregon Schedule 96) - `louisiana-ai-data-center-power-boom` (Louisiana Meta Phase 2) - Added `ferc-section-206-large-load-interconnection-rto-filings` (FERC Section 206 filings) This is an extremely productive and high-quality cycle! Let's call `finish_cycle` to complete this research cycle. I have updated all the relevant notes, recorded the FERC show-cause response event, resolved the corresponding thread, and registered a new forward-looking watch for the November 16, 2026 Section 205 filings.

I have completed this research cycle on the AI data center buildout and its regional electricity market impacts. Here is a summary of the key findings, events, and watches recorded: ### 1. Key Findings Persisted * **Oregon's Landmark Tariff Battle & Amazon's Legal Challenge (`[[oregon-pwr-act-pge-schedule-96-tariff]]`)**: * We documented Amazon Data Services' (ADS) **July 6, 2026 Application for Rehearing or Reconsideration** of the OPUC's Order No. 26-154. * Amazon is challenging the **Large Energy Use Facility (LEUF)** interconnection queue (loads > 20 MW) which "pauses" data center connections if they impede compliance with HB 2021 clean energy targets. * Amazon's key arguments include the unlawful subordination of the utility's traditional **"obligation to serve"**, undue discrimination against data centers, the illegal shifting of compliance burdens from the utility to the customer, and the practical infeasibility of OPUC's suggested bypass routes (like Direct Access, which is severely capped and restricted by concurrent Order No. 26-153). * **FERC Section 206 Show-Cause Filings & Structural RTO Shifts (`[[ferc-section-206-large-load-interconnection-rto-filings]]`)**: * We analyzed the landmark **July 20, 2026 resource adequacy reports** filed by the six major regional grid operators in response to FERC's Section 206 show-cause orders (Dockets EL26-67 through EL26-72). * **ISO New England (ISO-NE)** proposed a highly aggressive **"Bring Your Own New Generation" (BYONG)** framework and a plan to **exclude new large loads from system load forecasts used to set the capacity market's demand curves and Installed Capacity Requirement (ICR)**. This completely shields existing ratepayers from capacity price spikes, shifting all resource procurement costs directly onto data center developers. * **MISO** proposed a fast-track **Zero Injection Generator Interconnection Agreement (ZI-GIA)** to allow co-located generation to serve data centers without exporting to the grid, capping network upgrades at the substation level and bypassing multi-year network studies. * **Louisiana's 5,200 MW Phase 2 Gas Expansion & Ratepayer Backlash (`[[louisiana-ai-data-center-power-boom]]`)**: * We documented Entergy Louisiana's **Meta Phase 2 application (Docket U-37882)**, filed under the LPSC's fast-track **"Lightning Amendment"** (Lightning Initiative). * The proposal triples gas plant demand, adding **seven new gas-fired plants (5,200 MW)** and 240 miles of 500kV transmission lines to serve Meta's Richland Parish campus. Combined with Phase 1, Entergy plans to build **ten total gas plants (7,500 MW)** for a single hyperscaler. * On **August 4, 2026**, a coalition of consumer advocates (Alliance for Affordable Energy, UCS, etc.) launched a joint legal challenge, citing massive stranded-asset risks for captive residential ratepayers once Meta's 15-year contract ends. ### 2. Market Context Incorporated * We pulled and cited public-markets snapshots for **Vistra Corp (`[[/markets/VST/2026/08/17]]`)** and **Constellation Energy Corp (`[[/markets/CEG/2026/08/17]]`)** as primary independent power and merchant nuclear producers positioned to capture the upside of developer-funded co-located generation. ### 3. Threads and Watches Resolved / Registered * **Resolved Thread**: `019fc6bf-24db-7a1d-92c1-d650b023b348` ("FERC Large-Load Interconnection Show-Cause Deadline") has been resolved and recorded as a completed one-shot watch following the grid operators' filings. * **New Watch Registered**: Registered a new dated catalyst watch (`01a00ed9-35fa-7a97-ac44-de1a710b435f`) tracking the upcoming **November 16, 2026 Section 205 compliance filings** by ISO-NE, CAISO, and SPP, which will define the specific tariff rule text for large-load integration.
