Voters back data center limits in 40 of 41 local ballot measures across 10 states
Baxtel, citing Ballotpedia's tally, reports voters limited data centers or rejected pro-development proposals in 40 of 41 local measures on Nov 3, with 21 in Ohio. Examples include bans in Hubbard and Granville, Ohio, a permanent ban above 10 MW in Emporia, Kansas, and moratoriums in Wells and Wiscasset, Maine. Results are unofficial, and the Washington Post counted a lower figure (at least 38 jurisdictions). Upcoming votes: Clarksville, Arkansas (Dec 1) and Mandan, North Dakota (Dec 15).

Trenton, Ohio voters approve a 25 MW cap on data centers, blocking annexation for a 1,000 MW Amazon campus
Trenton voters approved Issue 17 on Nov 3 with about 80% support in unofficial Butler County results (results not yet certified). The charter amendment bars data centers above 25 MW in city limits, which blocks the city's plan to annex about 600 acres for a 1,000 MW Amazon campus. WVXU reports a 250 MW Prologis project in the city's industrial park is now in question; the article does not say what happens to it. Prologis helped fund the opposition campaign.

The buildout in Ohio
We track 4 data center campuses of 100 MW or more in Ohio (3 under construction, 1 operating and expanding). Together they announce 14,000 MW at full buildout; weighted by build stage, we expect about 4,740 MW to be running by 2030. That load lands on the PJM grid. Named power suppliers: AEP Ohio + on-site gas. The largest expected load is PORTS Technology Campus (2,400 MW by 2030, under construction). Added natural gas burn, from grid-supplied and on-site generation, comes to about 383.1 MMcf/d on an average day.
