48.5% of Indiana's Queue Is Solar

Start with the fuel mix, because in Indiana the fuel mix is the story: Solar makes up 48.5% of the Indiana interconnection queue, the single largest bucket by a wide margin in our sealed snapshot of June 11, 2026. Across the state, 456 projects are waiting to connect. Before that share gets read as a clean-energy forecast, the necessary caveat: a queue position is a request to connect to the grid, not a built, approved, or financed plant. These lists are aspirational, and most entries on them never reach steel in the ground.

Indiana's own data makes the point bluntly. Of those 456 requests, 293 are already marked withdrawn — a 64.3% withdrawal rate. Nearly two of every three projects that ever entered this slice have left it. So the honest reading of "48.5% solar" is not "Indiana is about to build a wall of panels," but "solar is what developers are filing for, and most of those filings will be filtered out before they energize." This is a cross-sectional census of one snapshot day. It counts what was published, not what will be built.

Why Lead With the Fuel Split

The fuel breakdown is where a state queue earns its keep as a signal. Counting projects tells you developer intent by technology, and Indiana's intent is overwhelmingly solar, with battery storage and hybrid configurations close behind. The table below comes straight from the snapshot's keyword-grouped categories.

Solar leads at 221 projects and 18,916 MW, which is why the 48.5% headline holds. Read qualitatively, a solar-led queue points to where developers see the cleanest path in this footprint: available land, falling module costs, and supportive policy. The 113 battery-storage requests are the second narrative — storage increasingly chases or pairs with solar to firm intermittent output, which is also why the 69 hybrid filings register as their own meaningful bucket.

Natural gas shows just 10 projects but 4,741 MW, the densest capacity-per-project profile in the state: gas filings are rare but individually large, typically combined-cycle plants sized for reliability. Wind sits at 42 projects and 4,314 MW, a modest presence next to solar but still material. The lone "Other" entry, at 1 project and 0 MW, is the tail of the distribution — proof that Indiana's queue is, in practice, a solar-and-storage queue with a thin thermal edge.

Battery storage and hybrid together account for 182 of Indiana's 456 requests — storage is the fast-rising second act behind a solar-dominated queue.

The capacity-per-project contrast is the detail recitation misses. Solar spreads 18,916 MW across 221 filings, the broad-base profile of utility-scale arrays. Natural gas concentrates 4,741 MW into just 10 requests, the dense profile of large combined-cycle plants. For a reader sizing where the next wave of Indiana connection activity is heading, the signal is unambiguous: solar dominates on count, storage rises fast behind it, and gas remains the dense-but-rare reliability play rather than a volume contender.

What the Snapshot Shows

• Solar is 48.5% of the Indiana queue, the dominant fuel by both count and capacity, per the sealed snapshot.

• Indiana lists 456 projects in its interconnection queue, totaling 39.1 GW of requested capacity.

• 293 Indiana projects are already withdrawn — a 64.3% withdrawal rate.

• 163 projects remain active, a 35.7% in-queue share.

• The largest single request is Sugar Creek - Cayuga CT 345.0kV at 1,540 MW, per the sealed snapshot.

That withdrawal share reframes everything above it. When a developer files an interconnection request, it stakes an early claim — often before land, financing, or offtake are locked. As study costs and network-upgrade estimates land, many of those claims are abandoned. Indiana's 64.3% withdrawn tells you the screening here is aggressive, and that the 39.1 GW headline is best read as a pipeline of intent rather than incoming supply.

Indiana at a Glance

The table pulls the state's headline figures directly from the sealed snapshot. Capacity appears in both megawatts and gigawatts as published; status is split into the buckets our methodology defines.

The 180 MW median, against a top request of 1,540 MW, says the queue is built from a broad base of utility-scale-but-not-giant projects with a thin tail of large ones. For anyone reading this slice as a demand signal, most of the activity is mid-sized solar and storage, not a handful of mega-plants. One structural note: a state's queue can span more than one grid operator, but Indiana's requests sit predominantly with MISO, the dominant operator across its footprint.

How Indiana Compares

Indiana is one mid-sized slice of a much larger national picture. Across all covered queues the snapshot holds 10,618 projects and 1600.7 GW, so Indiana's 456 projects are a focused regional view rather than a top-tier state by raw count. The table sets it against its parent operator and the national total; read the position qualitatively.

Indiana's queue is 48.5% solar against a national 39.0% — a more solar-concentrated slice than the country as a whole.

Indiana's 48.5% solar share runs hotter than both MISO's 46.4% and the national 39.0% — this is a more solar-concentrated queue than the average. Within MISO's broader footprint, the busiest single state is Michigan at 502 projects, a slice we break out in the Michigan interconnection queue report. For the operator-level view that contains Indiana, see the MISO interconnection queue report.

A caution on cross-state status reads: withdrawal percentages are not always comparable, because some operators drop withdrawn projects from their feed entirely. Indiana's MISO-published records carry a real 64.3% withdrawn figure; a slice showing 0.0% withdrawn is usually a feed that omits withdrawn records, not a queue where nobody left.

Methodology and the Grid Disclaimer

This report draws on public ISO/RTO interconnection-queue listings, via the grid-queue clock (sealed daily, content-hashed). The scope: generation and storage projects sitting in the interconnection queues of the U.S. grid operators (ISOs and RTOs) that publish a machine-readable queue, as captured by US Tech Automations' sealed daily grid snapshots. This is a census of the published queues, not of every project on every grid in the country.

All figures are computed directly from US Tech Automations' sealed daily grid-queue snapshots; nothing is estimated, modeled, or extrapolated. Fuel and status labels are grouped from each ISO's own categories, and the grouping rules appear in the display set. Vendor fuel and technology labels differ by ISO and are grouped into Solar, Battery Storage, Wind, Natural Gas, Hybrid and Other by keyword. Each ISO publishes its own status taxonomy; statuses are grouped into withdrawn, operational, still-in-queue, and unknown for feeds that publish no status. Some ISOs drop withdrawn projects from their feed entirely.

The grid disclaimer, restated: a queue position is a request to connect, not a built, approved, or financed project. Nothing here is a forecast of capacity that will come online. Indiana's own 64.3% withdrawal rate is the clearest in-snapshot evidence of how aspirational these lists are.

How we build the snapshot:

1. Collect. We pull each covered ISO's published interconnection-queue feed on its own schedule.

2. Normalize. Differing vendor fuel and status labels are mapped onto common buckets.

3. Seal. The day's normalized records are content-hashed and stored append-only, so the snapshot is reproducible.

4. Aggregate. We compute counts, capacity totals, medians, and status splits across the sealed records for the snapshot date.

Frequently Asked Questions

Q: How much of Indiana's queue is solar?
A: Solar is 48.5% of the Indiana interconnection queue, the largest single fuel bucket — 221 of the state's 456 requests, totaling 18,916 MW, per the sealed snapshot of June 11, 2026.

Q: Does a queue position mean the project will be built?
A: No. A position is a request to connect, not a built or financed plant. In Indiana's snapshot, 293 of 456 projects — 64.3% — are already withdrawn, so most queue entries never energize.

Q: Which grid operator covers Indiana's queue?
A: Indiana's requests sit predominantly with MISO, its dominant operator, which lists 3,786 projects across its full footprint. A state's queue can span more than one operator, but MISO is the home of this slice.

Q: Why is the median project only 180 MW when the largest is 1,540 MW?
A: The queue is built from a broad base of mid-sized utility projects plus a thin tail of large ones. The 180 MW median tells you typical activity is moderate solar and storage, not mega-plants like the 1,540 MW Sugar Creek - Cayuga CT 345.0kV request.

Q: Is the 64.3% withdrawal rate unusually high?
A: It reflects aggressive filtering, not an error. Developers file early, before land, financing, or offtake are locked; as study costs arrive, many requests are dropped. MISO publishes withdrawn records, so Indiana's 64.3% is visible rather than hidden by the feed.

Put Grid Data to Work

A sealed, daily queue snapshot is an early-demand signal, and each audience reads Indiana's 456 projects differently.

Project developers siting the next request can read the 48.5%-solar mix and 180 MW median to gauge where the queue is crowded and where a differentiated filing might clear faster. EPC contractors and equipment suppliers can treat the 113 battery-storage and 69 hybrid requests as a forward order-book signal, timing inventory and crews to the technologies developers are actually filing. Utilities and policy researchers can track the 64.3% withdrawal rate as a measure of how much of the 39.1 GW is real intent versus speculative placeholders.

US Tech Automations builds the automation layer on top of that signal: watching the published feeds for changes, routing new or withdrawn filings to the right internal team, and drafting the first-pass outreach when a relevant project appears or moves.
