Connecticut

Energy/Power is the dominant stress point: the debate is overwhelmingly about grid upgrades, interconnection, electricity prices, and whether data centers should bring their own power or reimburse ratepayers (CT Mirror). Capital Flows/Insurability is secondary: lawmakers and candidates are weighing whether Connecticut’s high power prices and cost-allocation rules will deter investment or protect consumers from stranded infrastructure costs (CT Mirror).

U.S. Senate: Sen. Richard Blumenthal (D) has made data-center rate insulation a federal campaign/policy issue through the bipartisan GRID Act, while Gov. Ned Lamont’s third-term campaign is being framed around electricity affordability and data-center cost shifting; state Rep. Josh Elliott (D) said he would take a tougher approach to data centers than Lamont or Republican challenger Ryan Fazio, who both said developers should pay their share of grid costs (CT Mirror, CT Mirror).

No statewide moratorium, ban, or pause has been enacted as of May 2026. Two 2026 bills meant to slow large-scale data centers — S.B. 245, which would have eliminated the 2021 tax incentives, and H.B. 5469, which would have regulated co-located data centers near power plants such as Millstone — died without a vote when lawmakers ended the session without taking them up (CT Mirror, Connecticut Public).

At the federal level, Sen. Richard Blumenthal’s bipartisan GRID Act would require new 20 MW+ data centers to secure their own power sources outside the grid, require existing facilities to cover costs otherwise shifted to customers, and impose "zero rate effect credits" for grid-upgrade costs attributable to data centers; it was introduced in February 2026 (CT Mirror). In Connecticut, lawmakers also considered repealing the 2021 data-center tax incentives via S.B. 245, but that bill died without a vote (CT Mirror).

None identified.

1) NE Edge, Waterford/Millstone Nuclear Power Station — proposed 300 MW co-located data center by developer Tom Quinn; prominent because it was cited in federal rate-insulation debate and would sit at the Millstone site, status: proposed/contested (CT Mirror). 2) A similar Quinn project next to a gas-fired power plant in Killingly — proposed, status: exploratory/proposed (CT Mirror). 3) Cigna data center renovation, Windsor — existing facility and the only company to qualify for the state incentive program; status: planned $386 million renovation, not a new hyperscale fight (CT Mirror).

No single statewide anti-data-center coalition clearly dominates in Connecticut. The most visible opposition comes from policymakers and aligned advocacy voices around electricity affordability, including Gov. Ned Lamont’s office, state Sen. Josh Elliott, and environmental groups that have pushed the governor on energy policy such as the Connecticut League of Conservation Voters and the Connecticut Sierra Club (their focus in the cited reporting is broader energy policy, not a dedicated data-center campaign) (CT Mirror).

None identified at the state political-surface layer as of May 2026. Talent and workforce dynamics in Connecticut surface primarily at the sub-state and labor-market level — county and municipal proceedings on named projects, regional building trades council positions, and utility commission workforce testimony — which are out of scope for the tracker's state-political-surface read.

Minimal to emerging. Connecticut already has "a few dozen smaller data centers," but CT Mirror reports the state has not yet seen major hyperscale AI campuses; the clearest named project is the proposed 300 MW NE Edge facility at Millstone in Waterford (CT Mirror).

"The deal for us and everybody else is we’re not doing any new major data centers if they suck energy, drive up prices," Gov. Ned Lamont said in February 2026 (CT Mirror).
