I. How the fund actually works
The Texas Energy Fund grew out of Senate Bill 2627 from the 2023 legislative session and the constitutional amendment voters approved that November. Its largest piece is a loan program for the ERCOT region: long-term, low-interest loans, at last public report around a 3 percent rate, for new or upgraded plants of roughly 100 megawatts or more. There are also completion bonus grants, which are extra money paid out if a plant comes online on schedule.
To qualify, a project has to be dispatchable. The PUCT's rules, following the statute, treat dispatchable as generation that can be told to run when the grid needs it and that does not lean on wind or sun. Battery storage, which stores power and releases it on command, is written out of the loan program by name at last public report. So is solar. The result is plain to state: the loan window is, in practice, a gas plant window.
II. The honest math on who waits in line
Look at what is actually trying to connect. ERCOT publishes an interconnection queue, the running list of projects seeking permission to plug into the grid, and for several years that queue has been dominated by solar and battery storage, with gas a smaller share. The exact totals move month to month, but the shape has held steady: tens of thousands of megawatts of solar and batteries, waiting, much of it on the coast near Houston.
Set that against the fund. The PUCT has advanced a first round of loan projects into due diligence, on the order of ten thousand megawatts of new gas capacity, per the commission's own announcements. None of it is the solar or storage sitting in the queue. The cheaper capacity, the kind that needs no fuel and can often be built faster, does not get the state's low-interest money. It waits in the same line it was already in.
III. Who holds the pen
Rules come from the PUCT, so the commission is where the definition lives and where it could change. Its three commissioners are appointed by the governor. The Legislature set the fund in motion and controls whether it grows, shrinks, or gets new categories, which means the next real fight over what counts as dispatchable is as likely to happen in Austin in 2027 as in a docket.
Developers sit on both sides. Gas plant builders have a reason to defend the current line. Solar and storage developers, many of them with projects around Houston and along the coast, have a reason to argue that a battery able to discharge on command is dispatchable by any plain reading. This desk is not aware of a final resolution; the rules as written still favor gas, and that is the honest state of play.
IV. Worth watching this month
1. Watch the PUCT's Texas Energy Fund page for any new round of loan or completion-bonus awards, which would show whether the gas-only pattern holds, and this is the one that actually matters.
2. Watch ERCOT's monthly interconnection queue report for the running split between solar, storage, and gas, a routine release that still tells you what is waiting.
3. Watch PUCT open-meeting agendas for any Texas Energy Fund rule item, since a change to the dispatchable definition would start there.
4. Watch early filings and interim charges ahead of the 2027 Texas legislative session for any move to let storage into the fund, which would be the clearest signal of change.
5. Watch your own bill and any ERCOT or utility notice about reliability charges, routine most months, worth a second look if a rate case opens.
Questions readers ask
Does the Texas Energy Fund ban solar and batteries outright?
Not from the grid, only from this pot of money. The loan and bonus programs are built around a dispatchable definition that, at last public report, leaves out solar and standalone storage. Those projects can still be built, just without the state's low-interest help.
Where does the money come from?
From the state, authorized when voters approved Proposition 7 in November 2023 and funded through Senate Bill 2627. It is public money, which is why the definitions are worth your attention. The pool for the ERCOT region is on the order of five billion dollars.
Why does ERCOT's queue being mostly solar and storage matter here?
Because it shows the cheaper capacity is already lining up on its own. If the state's goal is reliability at low cost, routing the help to gas while that queue waits is a choice, not a necessity.
Could the rules change to let storage in?
They could. The PUCT can amend its rules and the Legislature can rewrite the statute. Nothing public suggests an imminent change, so treat any such news as news when it comes.
