A Northshore Gen public evidence review

Facts over fear.Hobart data center.

How this page worksIndependent analysisPublic records firstCorrections in public

The current public record supports allowing the Hobart data center to move forward through its remaining reviews, with enforceable permit conditions, transparent operating records and continued public oversight.

That conclusion rests on approved utility agreements, planned generation and transmission resources, and Amazon’s air-permit application now under IDEM review.

Confirmed by record

Confirmed, with important operating context.

The submitted application lists 766 critical emergency generators and 16 support emergency generators. It describes them as backup equipment for interruptions in electrical service, not as the planned everyday power supply.

Project facts in context

The scale is real. The infrastructure plan is, too.

Amazon’s proposed backup fleet and the separately documented utility pathway are both necessary to understand the project.

Open the approval-path and oversight evidence

Why the project has a credible pathway

Infrastructure is being planned separately from backup power

IURC approved the NIPSCO customer contract and GenCo arrangements.
GenCo’s 3,000 MW portfolio includes a 400 MW battery resource supporting reliability and planning reserves.
MISO documents a separate 345-kV Hobart load-addition project.
Service is expected to begin in 2027 and ramp through 2032.

What should remain visible

A responsible path forward keeps oversight public.

The Amazon document is a submitted application, not an issued permit.
Amazon requested a FESOP/synthetic-minor permit—not a Title V permit.
Requested emission caps are not final permit conditions yet.
The proposed fleet is substantial; transparent operating records and enforceable conditions still matter.
Sound, operating records and future permit changes should remain public.

The documented power and permit pathway

Six roles that should not be blurred together

The diesel backup fleet, retail utility service, new generation, transmission planning and air-permit review are related—but they are not the same project or approval.

What residents should be able to verify

These updates separate active work, planned milestones, approved agreements and attributed public statements.

Construction and civil-plan reviewMass grading is active as of July 26, 2026, while vertical construction is reported scheduled for later in 2026. The submitted drawings show six future SBN520 building pads, approximately 115 acres of planned disturbance, mapped wetland buffers and stormwater controls. Indiana DHS also lists a July 21 Standard design release for Project 462383; that state record is not a local building permit or certificate of occupancy. Review the evidence →

Official IDEM processing statusIDEM lists Amazon Data Services Permit 089-50590-00739 as Initial Processing and records the application as received July 24, 2026. No draft, final or issued air permit is shown. Review the permit status →

Current court docket updateMyCase currently shows 45D11 as “Pending (active)” and records August motions, a response and a September 22 hearing on pending motions to dismiss. The related 45D10 summary is labeled “Decided,” but no public disposition or merits order was identified. Review the court status →

Latest City agenda trailThe August 17 Redevelopment Commission agenda lists an engineering-support agreement for data-site developments, while the September 3 Plan Commission agenda labels Hobart Tech Park item 26-18 “Tabled” and describes a proposed one-lot subdivision. Agendas show scheduled or considered business, not proof of approval. Review the source records →

Mayor’s construction updateHobart Mayor Josh Huddlestun’s January 2026 update tied a city payment to the first building going vertical and described 2026 as the expected construction year. It supports a planned milestone—not proof that vertical construction has already begun. Watch the video ↗

Community-agreement contextThe approved incentives include a 10-year real-property abatement and a 35-year qualified IT equipment exemption. The same public record schedules $175 million in community contributions, per-building impact payments and annual compliance review. Review accountability →

March 2026 community webinarAmazon and City leaders presented additional information about the power plan, water, generators, sound, site design and community programs. The recording is an attributed promise log—not an IDEM permit or independent study. Watch and review the evidence →

Public participationIf IDEM publishes a Hobart draft permit, its formal written-comment period is usually 30 days. The official notice—not a social-media post—will set the deadline, project contact and submission method. See the public-comment steps →

A living public record

Track what gets approved—not rumors.

Northshore Gen will reassess its current conclusion if public records show:

A new bridge-power or temporary-generation application
An IDEM permit or modification expanding operating authority
A confirmed utility-delay notice affecting planned service
A temporary-generation contract or material plan change
