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.

Bridging the Divide: How Data Centers Are Addressing Community Concerns
Vantage Data Centers and other industry leaders at Data Center World urged greater community engagement and coordinated policy on data center development.
- Main announcement: At Data Center World in Washington, DC, panelists including John Stephenson (Vantage Data Centers) and Ernest Popescu (Metrobloks) called for earlier community engagement, clearer communication about tax revenue, infrastructure investment, and the scale of projects (historical requests of 64 MW vs current requests of 500 MW to multiple gigawatts). The panel emphasized that developers are making multibillion-dollar decisions years in advance and face permitting timelines measured in years (e.g., transmission and generation buildouts), prompting consideration of self-generation solutions.
- Background and details: Panelists noted rising public concern over electricity rates, utility pricing, and perceived tax incentives (example cited: $100 million tax abatement for major hyperscalers). They urged coordination across federal, state, and local government, and a consortium of developers and hyperscalers to demystify misinformation and align policy, zoning, and community outcomes.

FERC Targets Grid Rules for Data Centers and Large Loads
The Federal Energy Regulatory Commission has ordered the nation’s six largest grid operators to justify or rewrite rules governing how large power users connect to the grid.
- Main action: FERC issued show-cause orders to PJM, MISO, Southwest Power Pool, CAISO, ISO New England, and NYISO, requiring them to explain within 60 days why existing tariffs remain just and reasonable or to propose reforms, and directing each operator and its transmission owners to file a resource adequacy report within 30 days. The orders affect markets serving roughly 200 million Americans across more than 30 states and the District of Columbia and target five reform areas (transmission study processes; cost-allocation; co-location/behind-the-meter generation; new transmission services for flexible large loads; evaluation of proximate generation).
- Context and details: The action builds on a Department of Energy large-load interconnection proceeding, follows review of more than 3,500 pages of comments, and is prompted by AI-driven data center demand. FERC said reforms should apply prospectively (not disturb finalized large-load arrangements) and left the broader DOE large-load docket open for potential additional action.

New York Confronts the Data Center Boom: Balancing Growth and Grid Reform
Democratic legislators introduced a bill for a three-year moratorium on new large data centers, and Governor Kathy Hochul directed the New York State Public Service Commission to open a regulatory proceeding to reform large-load interconnections.
- Three-year moratorium introduced by Democratic legislators: The bill would freeze state and local approvals for any new data center exceeding 20 MW for three years, require the Department of Environmental Conservation (DEC) to conduct a comprehensive environmental review and issue regulations, and direct the state utility regulator to adopt rules preventing residential ratepayers from shouldering energy cost increases attributable to data centers.
- Governor Hochul directed PSC to institute a proceeding under “Energize NY Development”: The PSC issued an Order Instituting Proceeding and Soliciting Comments (Case 26-E-0045) noting 11.9 GW of pending large-load projects in the NYISO queue (more than 8.3 GW entered in 2025); the Order lists six core objectives and sets initial comments due May 13, 2026 and reply comments due June 15, 2026, with a technical conference by Dec 31, 2026 and a white paper due Feb 12, 2027.

Demand-response programs can lower utility bills, but beware of on-site power restrictions, experts say
Virginia lawmakers enacted a law directing Dominion Energy and Appalachian Power to create demand-response programs for large energy customers and to expand utility procurement of energy storage.
- Main action: The law requires utilities Dominion Energy and Appalachian Power to offer demand-response programs for customers with an electric load of 25 megawatts or more, and directs utilities to procure more than 21,000 megawatts of power from facilities’ energy storage systems by 2045; the Virginia State Corporation Commission will work with an independent auditor to develop procurement criteria and review requests.
- Background and constraints: The article explains federal EPA limits (100-hour annual use for non-emergency generator operation with a 50-hour cap for non-testing/maintenance) and an EPA interpretive letter that prevents generators in RTO/ISO territories (e.g., PJM Interconnection) from using generators for demand response under the 50-hour cap; retrofitting to Tier 4 emissions can cost $100,000 to $500,000 or more per engine, and EPA enforcement can impose penalties in the hundreds of thousands of dollars; the piece also notes a lawsuit threat from the Southern Environmental Law Center against xAI for on-site generator emissions (three dozen natural gas generators, capacity 421 MW, potential >2,000 tons NOx/year).

Local Data Center Backlash Signals a Shift in How the Grid Must Evolve
The article highlights state and local regulators escalating restrictions and mandates on large-scale data center development in response to grid strain.
- Regulatory actions: Maine lawmakers advanced (then saw a veto) a temporary halt on new data center projects above 20 megawatts; Monterey Park voters approved a permanent citywide ban on data center construction; New Jersey officials unveiled a framework requiring mega-scale data centers to source their own clean energy and directly fund grid upgrades to avoid passing infrastructure costs to residents.
- Context and evidence:Electricity demand is projected to grow 15%-20% over the next decade (DOE), and an OBM survey found 64% of energy professionals say data center growth is accelerating flexible load management initiatives. The piece is an analytical overview calling for earlier utility coordination, flexible load management, automation, and transparency from developers and operators.

New York Assembly Approves One Year Pause on Large Data Centers
The New York Assembly has passed legislation to impose a one-year moratorium on permits for large-scale data centers, pending signature by Gov. Kathy Hochul.
- Main action: The bill, titled the Responsible Data Center Development Act, would impose a one-year moratorium on new permits for data center facilities requiring 20 megawatts or more, create a new electric and water rate class for data centers over 20 MW, require increasing percentages of renewable energy sourcing (on-site or via PPAs), and establish a host community benefit program for operators with peak loads over 20 MW. The bill also sets labor standards for construction projects with peak loads over 5 megawatts (prevailing wage, apprenticeships, workforce training) and requires all iron/steel used in construction to be made in the U.S.
- Context and background: The legislation is an omnibus combining provisions from at least four bills sponsored by Sen. Kristen Gonzalez (chair, Senate Internet and Technology Committee); it would become effective if signed by Gov. Kathy Hochul. The article notes Maine Gov. Janet Mills vetoed an 18-month moratorium in April, moratorium proposals exist in at least a dozen states, and New York is home to 132 data centers (clustered in Manhattan and Buffalo) according to Data Center Map.

Data center developers ousted from Monterey Park as voters approve permanent ban
Monterey Park has permanently banned data centers via Measure NDC.
- Measure NDC approved: More than 86% of voters approved a permanent ban on data centers in Monterey Park, codifying a moratorium in effect since late January; the ban bars any new computing facilities inside city limits and can only be overturned by another citywide vote. Key local facts: city population ~62,000, a proposed 250,000-square-foot data center by HMC Capital had its application withdrawn in April.
- Context and background: The article documents broader regional and state-level resistance — mentions a massive Box Elder County project backed by investor Kevin O’Leary, states that have introduced moratoriums or bans (Georgia, Michigan, New York, Pennsylvania, South Carolina, Vermont), and notes Maine’s legislature passed a statewide moratorium bill that was vetoed by Gov. Janet Mills.

Targeted Pressure: How Chinese Manufacturing Competition Impacts US States
The Information Technology and Innovation Foundation (ITIF) has published a report finding Chinese industrial policy is reshaping global manufacturing and harming industries across every U.S. state.
- Main finding & method: The ITIF report (June 1, 2026) analyzes one “national power industry” per state using County Business Patterns employment data, HS/SITC export proxies, and global market-share series to conclude that state-backed Chinese subsidies, export pushes, and overcapacity are driving down prices and pressuring U.S. producers in sectors such as semiconductors, batteries, aircraft, and fabricated metals.
- Key facts, numbers, and timelines:China plans ~$150 billion in semiconductor investment through 2030 vs. $52 billion under the U.S. CHIPS funding; the report cites $63.3 billion Chinese semiconductor spending in H1 2025, TSMC’s $165 billion U.S. investment announcement, GE Appliances’ $490 million Appliance Park investment (2025), and state/national export shares and HS-code trade series used throughout the analyses.

PFAS phase-out and liquid cooling: What US data center operators must do now
The Environmental Protection Agency (EPA) has designated PFAS as “forever chemicals” and under TSCA has delayed but maintained reporting requirements, with the reporting deadline pushed to January 31, 2027.
- Main announcement: The EPA/TSCA reporting requirement for PFAS use affects data center operators who must report PFAS use once requirements take effect; the EPA has extended the reporting deadline to January 31, 2027 after three prior extensions. The article frames this as a compliance shift that is already halting growth in two-phase immersion cooling and encouraging migration to PFAS-free options.
- Background and details: The piece notes 3M has phased out Novec, several U.S. states (New Jersey, Maine, Massachusetts, Minnesota, Washington) have reporting or ban plans, and market data shows single-phase DTC holds a 55% market share in 2026, using a 75% water / 25% glycol coolant; Schneider Electric (with Motivair) is promoting PFAS-free single-phase DTC solutions.

Fiber Industry Confronts Marathon of BEAD Compliance, Data Center Backlash
Panelists at Fiber Connect 2026 warned that the broadband buildout has shifted from a sprint into a marathon, citing BEAD compliance, surging hyperscaler demand, tripling pole make-ready costs, and rising local opposition to data centers.
- Main announcement/action: Panelists at Fiber Connect 2026 (Orlando, Fla., May 18, 2026) said the industry now faces a prolonged delivery cycle driven by BEAD milestone-based reimbursements, surging hyperscaler demand, and sharply higher pole make-ready costs; speakers noted roughly 300% increase in pole make-ready costs and that rural per-mile build costs rose from $20,000–$25,000 to about $100,000 per mile.
- Background and details: The panel (BroadbandLive session hosted by Broadband Breakfast) highlighted that NTIA→state→subgrantee milestone reimbursements will slow cash flow, state broadband offices are stretched as ARPA projects wind down, and local opposition / moratoria (citing Maine Gov. Janet Mill’s veto and Georgia water-rate dispute) are driving calls for more deliberate siting and coordination with environmental/permitting agencies.
