ISO-NE GridWorks presents Millinocket thermal-storage pilot and load-shifting economics
Source: GridWorks Energy Consulting · Sep 23, 2026GridWorks Energy Consulting’s 9/23/2026 presentation says its Millinocket, Maine thermal-storage pilot is “Now 6, moving to 8 homes,” is “Sponsored by Efficiency Maine Trust,” and has “Plans and funding to scale up starting next summer.” The deck also says Millinocket sits behind the ISO-NE “Keene Road Constraint,” described as “the most congested node on the ISO-NE electric grid,” and that the nearby wind farms cause ISO-NE to curtail them about “10% of the hours during the heating season.” It further claims the homes have avoided buying electricity during monthly coincident peak hours over two heating seasons.

ISO-NE cites FERC large-load integration show-cause order and new interconnection deadline (June 2026)
Source: ISO New England · Sep 24, 2026ISO New England says FERC’s large-load integration action may force tariff reform because “existing tariffs may be unjust and unreasonable due to lack of clear large load provisions.” ISO-NE also notes a Nov. 16 deadline for changes to the region’s interconnection processes to account for “large and co-located loads,” and identifies reform areas including faster transmission-study processes, cost allocation, co-location treatment, flexible load services, and generator interconnection reforms.

Update on Recent and Upcoming Regional Activities
Source: ISO New England · Jul 31, 2026ISO New England’s July 31, 2026 memo says the region filed an informational report on July 20 “in compliance with a June 18 order issued by the Federal Energy Regulatory Commission (FERC) related to the integration of large loads and co-located loads, such as data centers,” and that ISO-NE has opened “a six-month engagement period on transmission cost allocation” under FERC Order 1920. The memo also says the Transitional Cluster Study interim report covered “23 interconnection requests totaling approximately 4,800 MW,” and that ISO expects to issue the final report on August 6 before tendering draft interconnection agreements later in August.

Maine OPA – Proposed Amendments to the ACR Process
Source: ISO New England · May 28, 2026ISO New England’s “Maine OPA – Proposed Amendments to the ACR Process” (dated 2026-05-28) is a policy document about transmission planning and cost allocation, not a specific data-center project. It says the proposed amendment would “restrict the asset condition project designation” to damaged or destroyed facilities and warns that “substantial upgrades” should instead go through regional planning; it also explains that the Transmission Cost Allocation process can keep non-regional upgrade costs out of regional rates. These points indicate regulatory and cost-allocation risk for transmission-related development in Maine, but the document does not identify a data-center queue, site, operator, or project.

Lewiston City Council shoots down data center proposal
The Lewiston City Council unanimously rejected a proposal by MillCompute LLC to convert part of the Bates Mill No. 3 building into an A.I. data center and innovation office space.
- Main action: The Lewiston City Council unanimously voted to reject the proposal from MillCompute LLC to use 85,000 square feet of Bates Mill No. 3 for an A.I. data center / modern office/innovation space; the developer had requested a 20-year TIF / credit enhancement returning 90% of property taxes for years 1–10 and 85% for years 11–20, which was opposed by residents.
- Background and details: The proposal was public for about one week before strong public opposition surfaced on social media and at a standing-room-only council meeting; speakers cited environmental concerns and potential utility rate spikes, City Administrator Bryan Kaenrath had previously supported the project but said future data center proposals will be reviewed “very carefully”.

Letter: Maine must consider big down sides of AI
John M. Mishler (letter author) urges Mainers and their lawmakers to carefully weigh the benefits of artificial intelligence against concrete risks, notably workforce displacement and the resource demands of AI data centers.
- Main announcement: The author warns Mainers to be concerned about AI and calls on lawmakers to evaluate workforce restructuring and the environmental/resource costs of AI data centers; cites Frank Wilczek: “What worries me is not so much artificial intelligence but natural stupidity.” The letter references reporting of potential loss of employment for thousands of skilled workers (Business Insider) and the energy and water needs of AI facilities (Pew Research, BBC). The author previously wrote the column “Trump: King of the Unthinking” (Storm Lake Times Pilot, Oct. 24).
- Background and supporting details: Photo credit notes the Stargate artificial intelligence data center complex in Abilene, Texas (AP photo, Sept. 22, 2025); linked sources include New Scientist (Wilczek), Business Insider (job-loss reporting), Pew Research (data-center energy use), and the BBC (cooling water impacts). The letter is an opinion/appeal rather than a policy proposal; it urges deliberation rather than prescribing specific legislative actions.

Lewiston mill eyed for $300M AI data center
Lewiston officials will be asked next week to green light a $300 million artificial intelligence data center at Bates Mill No. 3.
- Project details: The proposal is for a $300 million Tier III AI data center at Bates Mill No. 3 in phased construction; the first two floors (~85,000 square feet) will host the data center with the upper two floors converted to office/innovation space. The development includes a planned 20–24 megawatt natural gas co-generation system in the Boiler House (phase two) and a 20-year tax increment financing (TIF)/credit enhancement that returns 90% of property taxes to the developer for years 1–10 and 85% for years 11–20, with the city receiving $798,250 in property taxes annually for the first 10 years. The developer expects 20–30 jobs and describes cooling as efficient closed-loop systems to minimize water use.
- Background and conditions: The building owner Bill Johnson partnered with MillCompute LLC after TD Bank’s 2020 departure; the city memo requires the project to not adversely impact water quality, water supply, environmental conditions, or create local/regional power shortages. City staff cite robust fiber connectivity, ample natural gas, and Central Maine Power reports of adequate excess electricity for the near- and medium-term. The council will be asked to approve a joint development agreement to start the project.

What to Do With Remaining BEAD Funds, a.k.a 'Non-Deployment'?
The National Telecommunications and Information Administration (NTIA) issued the BEAD Restructuring Policy Notice prioritizing lowest-cost bids, voiding previously approved state plans, and rescinding authorization for non-deployment activities.
- Main action and effects: NTIA’s June 6 BEAD Restructuring Policy Notice requires states to resubmit plans within 90 days, eliminates scoring criteria for labor practices, climate resilience, and affordability, and replaces multi-criteria evaluation with a single metric—total BEAD cost per location; NTIA now estimates roughly $21 billion in BEAD “savings” across 56 states and territories.
- Background and specifics: States had planned to use non-deployment funds for workforce development, digital literacy, telehealth, device subsidies, and community anchor institution connections (examples: Louisiana $510 million, Florida ~$200 million); litigation risk and Congressional pushback (bipartisan letters, proposed RECAPTURE Act) are active, and NTIA has promised guidance in early 2026. The draft White House executive order would link eligibility for remaining funds to state AI regulatory frameworks, adding a legal and political dimension.

Top Environmental Victories of 2025
The Sierra Club announces a roundup of its top environmental victories in 2025.
- Major announced actions: The article catalogs specific legal, legislative, and advocacy wins including: stopping a proposed public-lands sell-off after Congressional withdrawal; passage of the Climate Change Superfund Act in New York (following Vermont in 2024) and introduced bills in California, New Jersey, Maryland, Massachusetts, and Maine; legal victories blocking Commonwealth LNG (coastal use permit terminated) and two lawsuits creating guardrails on data centers in Kansas and Michigan; NEVI program restart unlocking $2.7 billion for EV charging; and a $744 million jury verdict against Chevron for coastal damages in Louisiana.
- Background and additional details: The piece lists species and land protections (Northern Rockies wolves, Colorado bison, Rice’s whales), closure of Merrimack Station (final New England coal plant) and repeal of an Ohio coal-bailout that would have cost nearly half a billion dollars, passage of Utah’s balcony solar law allowing small plug-in systems without utility approval, a coalition delivering ~500,000 public comments to defend the Roadless Rule (including 40,000 from Sierra Club advocates), and a world-record origami action sending more than 86,000 paper fish to oppose Enbridge’s Line 5.

The Five Types of Electro-Industrial States
Rocky Mountain Institute presents a typology classifying US states into five electro-industrial archetypes.
- Main announcement/action: RMI authors classify states into five archetypes — Momentum Hubs (Arizona, California), Fast‑Track Builders (Texas, Georgia, South Carolina, Florida, Colorado, Utah, Nevada, New Mexico, Oklahoma, Tennessee, Ohio, Idaho), Policy Champions (New York, Michigan, Virginia, Oregon, Washington, North Carolina, Wisconsin, Illinois, Maryland, Minnesota, Massachusetts, Pennsylvania), Open‑Door Starters (Vermont, Wyoming, Nebraska, Kansas, North Dakota, South Dakota, Mississippi, Iowa), and Early‑Stage Starters (Missouri, New Hampshire, Kentucky, Maine, Alabama, Louisiana, Indiana, West Virginia, Montana, Arkansas). The typology is based on policy reliability, regulatory ease, economic capacity, physical infrastructure (power and interconnection), and market momentum.
- Background and details: The analysis highlights that market momentum and policy reliability should operate in tandem; low regulatory burdens accelerate short-term investment but may strain local housing and infrastructure without accompanying policy ambition. The authors reference the report GREASE Lightning as a policy playbook for designing investment-led, state-driven electro-industrial strategies.

Hurricanes in 2024 led to the most hours without power in the United States in 10 years
U.S. Energy Information Administration reports that U.S. electricity customers experienced an average of 11 hours of electricity interruptions in 2024, nearly twice the annual average of the previous decade.
- Main finding: The EIA’s Electric Power Annual 2024 shows U.S. customers averaged 11 hours of interruptions in 2024; Hurricanes Beryl, Helene, and Milton accounted for 80% of hours without electricity, and interruptions attributed to major events averaged nearly 9 hours in 2024 versus nearly 4 hours (2014–2023). The report uses industry metrics SAIDI and SAIFI to characterize outages.
- Details & state impacts: The report cites South Carolina averaged nearly 53 hours without power in 2024; Hurricane Beryl left 2.6 million Texas customers without power (July), Hurricane Helene left 5.9 million customers across 10 states (with at least 1.2 million in South Carolina), and Hurricane Milton left 3.4 million Florida customers without power; Hawaii averaged 4.4 interruptions, while several states (Arizona, South Dakota, North Dakota, Massachusetts) averaged less than 2 hours of interruptions.
